The amount spends on rent is $750.

In order to show mathematical issues, the "pie chart," often referred to as a "circle chart," divides the circular statistical visual into sectors or portions. A proportionate amount of the entire is indicated by each sector. The Pie-chart is now the most effective method for determining the composition of something. Pie charts typically take the role of other graphs, such as bar graphs, line plots, histograms, etc.

Given a pie chart shows,

spent on food = 20% of salary = 1/5 of salary

spent on utilities = 3/10 of salary

and rest on rent let be x

salary  = $1500

so 1500 = spent on food + spent on utilities + spent on rent

1/5 of 1500 + 3/10 of 1500 + x = 1500

1/5 of 1500 = $300

3/10 of 1500 = $450

300 + 450 + x = 1500

x = $750

Hence the amount spent on rent is $750.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

The parallel sides are DG and EF.

The non-parallel sides are DE and GF.

The slope of DG.

Two points pass through by DG.

(-2, 2) and (1, 2)

Slope = (2 - 2) / (1 + 2) = 0/3 = 0

The slope of EF.

Two points pass through by EF.

(-4, -3) and (3, -3)

Slope = (-3 + 3) / (3 + 4) = 0 / 7 = 0

The length of DE.

D = (-2, 2)

E = (-4, -3)

Length of DE = √(-4 + 2)² + (-3 - 2)² = √(4 + 25) = √29

The length of GF.

G = (1, 2)

F = (3, -3)

Length of GF = √(3 - 1)² + (-3 - 2)² = √(4 + 25) = √29

Thus,

The slope of the parallel sides is equal.

The translation is done to the right 5 units and up two units.

Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.

Given that vertices of ΔABC are A(2, 1), B(4, 4) and C(4, 1).

And vertices of ΔDEF are D(7, 3), E(9, 6) and F(9, 3).

Translation towards left or right changes the x coordinate and translation towards up or down changes the y coordinate.

Translation toward right and up results in positive translation and towards left and down results in negative translation.

A(2, 1) becomes D(7, 3) when D(2 + 5, 1 + 2).

Similarly,

B(4, 4) becomes E(9, 6) when E(4 + 5, 4 + 2)

C(4, 1) becomes F(9, 3) when F(4 + 5, 1 + 2)

So the translation is 5 units right and 2 units up.

Hence the translation is 5 units right and 2 units up.

The solution of the two simultaneous equations given in the graph is; (-6, -3)

We are given the simultaneous equations as;

y = ³/₂x + 6   ------(1)

y = -¹/₂ - 6    -----(2)

Now, the solution of this 2 simultaneous equations would be the coordinate of the point on the graph where the two graphs meet each other.

Let us first solve the equations by elimination method;

Subtract eq 2 from eq 1 to get;

0 = 2x + 12

Subtract 12 from both sides to get;

2x = -12

x = -12/2

x = -6

Put -6 for x in eq 1 to get;

y = ³/₂(-6) + 6

y = -3

The number of bottles of soda be 8 and the the number of bottles of juice be 10 when Piper to the grocery shop and purchased Coke and juice bottles.

Given that,

Piper to the grocery shop and purchased Coke and juice bottles. Each soda bottle contains 50 grams of sugar, whereas each juice bottle contains 40 grams.

Piper bought 2 more bottles of juice than soda, and they all have 800 grams of sugar in total.

We have to determine out how many bottles of juice and soda were bought, y, and x, respectively.

We know that,

Let the number of bottles of soda be x.

And the the number of bottles of juice be y.

So,

We get the system of equation as

y = x+2 ----------->equation(1)

50x+ 40y=800 ------------->equation(2)

Substitute y =  x+2 in equation(2)

50x+ 40(x+2) =800

50x+40x+80 =800

90x= 800-80

90x =720

x=720/90

x=8

Now substitute x=8 in equation(1)

y= x+2

y=8+2

y= 10

Therefore, The number of bottles of soda be 8 and the the number of bottles of juice be 10 when Piper to the grocery shop and purchased Coke and juice bottles.

because 7.21 is twice the number 3.605

Two angles and a side of a triangle are equal in these two triangles thus these triangles are congruent.

Angles in a right triangle are easily calculated. A right triangle has a right angle, often known as a 90 angle. The angle sum formula, which asserts that the sum of the angles in a triangle is always equal to 180 degrees, can be used to quickly determine the missing angle given one other angle of the triangle is known.

Given, two triangles in the figure. Where we can see that one side of that triangle is the same that is 4. and one angle is 90 degrees in both triangles and one angle is the same as shown in the figure.

Thus we can say that one side and two angles of the given triangle are equal.

Since Triangles are said to be congruent if two of one triangle's angles and one of its sides are equal to those of another triangle. This indicates that we are given a triangle's two given angles as well as one side that is not the side next to the two supplied angles. Such a triangle can be resolved by utilizing the Law of Sines to determine each of the other two sides and the Angles of a Triangle to determine the other angle.

Therefore, These two triangles are congruent because they have two equal angles and one equal side.

The answer to this equation using the rule of three is 68.

Let the time taken by the first team to finish the building be T. Since the teams are identical, the time taken by the second team to finish the building would also be T.

After 8 workers move from the second team to the first team, the first team has 16 + 8 = 24 workers and the second team has 25 - 8 = 17 workers.

Let the time taken by the first team after the worker change be T1 and the time taken by the second team after the worker change be T2.

Since both teams finish the construction at the same time, we can say that T1 = T2.

By the rule of three, we know that T/16 = T1/24 and T/25 = T2/17.

Cross multiplying and equating we get, 16T = 24T1 and 25T = 17T2.

So T1 = (24/16)T = 3/2T and T2 = (25/17)T.

The ratio of the time spent working by the teams after the worker change to the time spent working by the original teams is (3/2T + (25/17)T) / T = (3/2 + 25/17) = (317 + 252)/(2*17) = 51/17.

Therefore, p + q = 51 + 17 = 68.

The provided statement states that the equation's slope intercept form is y = -2x + 1.

A line's slope is the measure to the amount y increases when x increases by a specific amount. The a line's slope describes its steepness or the rate at which y climbs as x rises. The slope is consistent wherever along the line (the same).

The following is a representation of the slope intersect form equation:

y = mx + b

where

m = slope

b = y-intercept

Consequently, using the known locations,

(3, -5)(-2, 5)

m = 5 - (-5) / -2 - 3 = 10 / - 5 = -2

Consequently, let's use b to find (3, -5)

y  = -2x + b

-5 = -2(3) + b

-5 = -6 + b

b = -5 + 6

b = 1

y = -2x + 1

The following is how we can employ the equation to work out whether x = 1 and x = 2:

The first scenario is where T4 beats T1,73 beats T2, and T4 beats T3, and the second scenario is where T4 beats T1, T2 beats T3, and T4 beats T2.

Considering the first scenario:

The probability of T4 beating t1 is 4/(4+1).

The probability T3 beats T2 is 3/(3+2).

The probability T4 beats T3 is 4/(4+3).

Therefore the first scenario happens with probability 4/(4+1)*3/(3+2)* 4/(4+3)

Considering the second scenario:

The probability of T4 beating t1 is 4/(1+4).

The probability T2 beats T3 is 2/(2+3).

The probability T4 beats T2 is 4/(4+2).

Therefore the second scenario happens with probability 4/(1+4)*2/(2+3)* 4/(4+2)

By summing these two probabilities, the probability that T4 wins is 4/(4+1)*3/(3+2)* 4/(4+3) + 4/(1+4)*2/(2+3)* 4/(4+2) which is equal to 256+525 = 781.

There are 5 significant figures in the number 57,030 joules.

Step-by-step explanation:

In general, significant figures are all the digits in a number that are used to express precision, including all digits except:

Leading zeros (zeros that come before the first non-zero digit).

Trailing zeros (zeros that come after the last non-zero digit but before the decimal point).

Trailing zeros that are after a decimal point, if the decimal point is not at the end of the number.

In the number 57,030, all of the digits are used to express precision, so all of the digits are significant figures. The zeros between the 5 and the 7, and between the 3 and the 0, are not leading zeros or trailing zeros, so they are also significant figures. The zero after the 3 is a trailing zero, but it is after a decimal point (even though the decimal point is not written), so it is not a significant figure.

Therefore, there are 5 significant figures in the number 57,030 joules.

We can then use this ratio to convert the height of the model, which is 10 inches, to the corresponding height of the actual sailboat. To do this, we multiply the height of the model by the conversion factor, which is 1.5 feet/inch:

10 inches * 1.5 feet/inch = 15 feet
