72 is what percent of 45​

Answer:

D. 1 square/ 4 meters = 12 square/48 meters

Step-by-step explanation:

You scale down by simplifying the fraction of 12/48. You would divide both 12 and 48 by 12, since it is the highest divisor. And once you divide the two you get 1/4.

Answer:

1/6

Step-by-step explanation:

since area is l*w=a that means 3 1/3*2 1/5 is teh same as 3.333333*2.5 which is 8.33333333333 or 8 1/3 since you are multiply using the square method we just need to do 1/2 *1/3 this gives us 0.166666666667 or 1/6  

hope this helps this is 100% correct

Answer:

-2

Step-by-step explanation:

When 2 lines are parallel that means they have the same slope but diffrent y-intercepts. You can also double check this by counting what the slope is on the graph itself, the red line's equation is y=-2x + 2 while the green line's in y = -2x - 4.

Hope this helps!! :)

Answer:

P≈14.14

Step-by-step explanation:

Diagonal

5

Using the formulas

P=4a

d=2a

Solving forP

P=22d=2·2·5≈14.14214

Answer:

About 14

Step-by-step explanation:

The diagonal BD is the hypotenuse of the triangol ΔBCD. You can find the lenght of the side BC (BC = BD × cos α = 5 × cos 45° = 3.54) or the lenght of the side CD (CD = BD × sin α = 5 × sin 45° = 3.54). Now you can multiply 3.54 by four to find the perimeter (P = 3.54 × 4 = 14.16).

Answer: 14.16 (I don't know the unit of measurement).

I hope I helped you :D

Answer:

first you find the common denominator, it is 6.

so the numbers would stay the same. now that our denominators are the same we shall add.

1+2 = 3

3/6.

You can simplify by thinking what multiplication table is 3 and 6 in? its 3 so simplify

3/6 divide both by 3

you get 1/2 so your final answer shall be 1/2

Answer:

y=-3

Step-by-step explanation:

First, you want the slope.

The slope is

[tex]\frac{-3-(-3)}{-3 - 5} = \frac{0}{-8}\\[/tex]

0/-8 = 0, so the line is horizontal.

the y-intercept must be -3 because it never changes.

So the equation must be

y=-3

Slope:-

[tex]\\ \rm\hookrightarrow m=\dfrac{-3+3}{-3-5}=0[/tex]

Equation of line in point slope form

[tex]\\ \rm\hookrightarrow y+3=0(x-5)[/tex]

[tex]\\ \rm\hookrightarrow y+3=0[/tex]

[tex]\\ \rm\hookrightarrow y=-3[/tex]

Answer:

2m/3-4n

Step-by-step explanation:

Answer:

a. Total field goal points scored in the first two quarters, in simplest linear expression form is: 3x - 4.

b. The total points scored in the game, in simplest linear expression form is: 6x - 1.

a. The goal points scored in the first two quarters are expressed in linear forms as: 2x - 6 and x + 2.

The total field goal points in the first two quarters = 2x - 6 + x + 2

Add like terms

3x - 4

b. The total points scored in the game = 2x - 6 + x + 2 + 2x + x - 6 + 9

Add like terms and simplify the expression

2x - 6 + x + 2 + 2x + x - 6 + 9

6x - 1

Step-by-step explanation:

Work Shown:

[tex]\frac{\sin(a)}{a}=\frac{\sin(b)}{b}\\\\\frac{1}{10}=\frac{\sin(b)}{9}\\\\\frac{\sin(b)}{9} = \frac{1}{10}\\\\\sin(b) = 9*\frac{1}{10}\\\\\sin(b) = \frac{9}{10}\\\\[/tex]

Answer:3

Step-by-step explanation:

250-3= 247,

If each classmate has to get a whole cookie then

247/3= 3.38

You cannot give more than you have (she can’t give 3.38 cookies because those aren’t whole cookies, she cannot also give 4 cookies because she doesn’t have enough to give 4 one person will probably get only 3 or something) so the only option is to give 3 cookies to each classmate.

Answer:

Answer is 6.40 units

Step-by-step explanation:

Pythagorean theorem

a^2+b^2=c^2

fill in the sides for a and b

4^2 + 5^2 = c^2

simplify

16+25 = c^2

41 = c^2

Sqrt both sides

c = 6.4

Answer:

6.40 units

Step-by-step explanation:

You can use the equation a^2+b^2=c^2 for this. C is the unknown and the hypotenuse.

In this case, 4^2+5^2=c^2.

16+25=c^2

41=c^2

sqrt{41}= c

Approximately 6.40312

Let the numbers be: x and y

Now, we will set up the equation with the variables and given info..

[tex]x \times y = 36 \\ x + y = - 15[/tex]

Solve using the substitution method

[tex]x \times y = 36 \\ x = - 15 - y[/tex]

[tex]( - 15 - y)\times y = 36[/tex]

[tex]y = - 12[/tex]

[tex]x = - 15 - ( - 12)[/tex]

[tex]x = - 3[/tex]

➪ Therefore, The two numbers are: -12 and -3

Answer:

x = 17

Step-by-step explanation:

2x = 5x - 51

51 = 5x - 2x

51 = 3x

x = 51/3

x = 17

2x = 5x -51

2x + 5x = -51

7x = -51

7x ÷ 7 = -51 ÷7

x = -7.2

Answer:Richter scale measures intensity of earthquake as power of 10. The intensity of the Chilean earthquake( year 1960) was approx 316.23 times greater than the earthquake in Haiti (year 2010)How to measure the greatness of earthquakes from Richter scale's intensities?Suppose that the first measured earthquake was of  intensity (on Richter scale)Suppose the second measured earthquake was of   intensity(on Richter scale).It is a fact that each unit of the the Richter scale measurement increases as the power of 10.So if b = a + 1, then the second earthquake was 10 times greater than the first earthquake.If we have b = a + x, then we have:Second earthquake was  times greater than the first earthquake.As it was given that the earthquake in Haiti was of 7.0 intensity on Richter scale, and that the Chilean earthquake was about 9.5 intensity on Richter scaleThe difference is 9.5 - 7 = 2.5

Answer:

C.35 cm

Step-by-step explanation:

[tex] (\frac{21}{3} ) \times 5 = \\ 7 \times 5 = 35[/tex]

The length of the longer part of the second segment is 35cm.

"Proportion is explained majorly based on ratio and fractions. A fraction, represented in the form of a/b, while ratio a:b, then a proportion states that two ratios are equal. Here, a and b are any two integers."

"Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion"

Given here,

length of the shortest line segment is 21cm.

and ratio in which the length segment are been divided is 3:5

the length of the longest segment will be 21/3 * 5 = 35

Hence the length of the longest side will be 35cm.

Answer:

If the mother (red line) cycles at 12 mph, it means that in half an hour (x=0.5) she cycled for 6 miles.

The daughter (blue line) walks at 1/3 of her speed, or 4 mph. It means that in half an hour she traveled 2 miles, and 4 miles after an hour.

Assuming that they start at the same point at distance zero, it's just joining the dots.

Answer:

x = 20

y = -7

z = -11

Step-by-step explanation:

Sum of interior angles of a rhombus = 360°

The opposite angles of a rhombus are equal to each other.

The adjacent angles are supplementary (add up to 180°)

Therefore,

66 + (6x - 6) = 180

⇒ 66 + 6x - 6 = 180

⇒ 6x = 180 - 66 + 6

⇒ 6x = 120

⇒ x = 120 ÷ 6

⇒ x = 20

66 + (-10z + 4) = 180

⇒ 66 - 10z + 4 = 180

⇒ -10z= 180 - 66 - 4

⇒ -10z = 110

⇒ z = 110 ÷ -10

⇒ z = -11

(6x - 6) + (-10y - 4) = 180

⇒ 6x - 6 - 10y - 4 = 180

⇒ 120 - 6 - 10y - 4 = 180

⇒ -10y = 180 - 120 + 6 + 4

⇒ -10y = 70

⇒ y = 70 ÷ -10

⇒ y = -7
