Answer:

26$

Step-by-step explanation:

10+ (5x3) +1= 26$

Answer:

26

Step-by-step explanation:

10+($5x3)+1

the first thing you would want to do is 3x5 because you have 3 5 dollar bills

and the answer for that is 15 then you add 10+15 which is 25 plus the 1 we have left which is 26

so 26 is your finally answer

Answer

2nd and last

Step-by-step explanation:

Answer:

the third option is the answer, y= 1/4x-1

Step-by-step explanation:

graph line in standard form:

[tex]y = mx + c[/tex]

where m = slope and c = y-intercept

1) find the slope

slope formula:

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

use the two coordinates given in the graph

i/ (0,-1)

x1 = 0

y1 = -1

ii/ (4,0)

x2 = 4

y2 = 0

substitute the values into the formula

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

[tex] \frac{0 - ( - 1)}{4 - 0} [/tex]

[tex] \frac{1}{4} [/tex]

thus, m = 1/4

2) find the y-intercept

* y-intercept is the value of y that cuts through the y-axis

based on the graph, the y-intercept is -1

thus, c = -1

3) substitute the value of m and c into the standard form formula

[tex]y = mx + c[/tex]

[tex]y = \frac{1}{4} x - 1[/tex]

Step-by-step explanation:

Answer:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

Answer: 400=12.50x+50

400-50=12.50x

350=12.50x

350÷12.50=x

28=x

Step-by-step explanation:

a²+b²=c² is pythagorean theorem :)

Pythagorean theorem

in the right angle triangles there is a relationship that governs the length of the three sides. if we knows the length of any two sides, the third side may be calculated by the use of the Pythagorean theorem.

This theorem states that the square on the hypotenuse of a right angled triangle is equal to the sum of the squares on the remaining two sides.

we only use Pythagorean theorem to find the length of the missing side of a right angled triangle only.

Answer:

The correct answer is indeed C. Rotation and dilation :)

The similarity transformation that maps ΔDEF to ΔDEF is rotation and dilation.

Dilation involves scaling an object by multiplying the distance between all of its points and a fixed point, called the center of dilation, by a constant factor.

The factor can be greater than 1, in which case the object gets larger, or it can be between 0 and 1, in which case the object gets smaller.

The center of dilation can be located anywhere in the plane.

We have,

Rotation and dilation are both transformations in geometry that can be used to change the size and shape of an object.

Rotation involves rotating an object around a fixed point, called the center of rotation.

The object remains the same size and shape, but its orientation changes.

Dilation involves scaling an object by multiplying the distance between all of its points and a fixed point, called the center of dilation, by a constant factor.

Now,

We see that,

There is rotation and dilation on ΔDEF.

Thus,

The similarity transformation that maps ΔDEF to ΔDEF is rotation and dilation.

so 4 + x < 22

Answer: $720.47

Step-by-step explanation:

Answer:

The coordinates are (0,b)

Step-by-step explanation:

Here, we want to find the coordinates of the midpoint F

as we can see, F is between A and B

we proceed to use the midpoint formula

The midpoint formula is;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

(x1,y1) = (-3a, b)

(x2,y2) = (3a, b)

The substitution of these values will thus yield;

(-3a + 3a)/2, (b + b)/2

= (0/2), (2b/2)

= (0, b)

Blank1= C:12.593

Blank2= C:593

Step-by-step explanation:

First we need to remember the equation for future value of annuity

FV=C(((1+i)ⁿ-1)/i

PV is 500

i=0,05/12=0,004

n=24 months

FV=500((1+0,0041)²⁴-1)/0,004

FV=12.593

If the total of payments were 500x24=12.000

it means for interest is 593

Answer:

100 i belive

Step-by-step explanation:

you add 4+46=50x2=100

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is 4 gal of pure ethanol is added to 46 gal of 2% ethanol.

In 46 gal of 2% ethanol, we have (46 x 0.02) = 0.92 gallons of pure ethanol.

When 4 gal of pure ethanol is added, total ethanol in the mixture = 4 + 0.92 = 4.92 gallons

Total mixture quantity in gallons = 46 + 4 = 50 gallons

The percentage of the ethanol in the mixture will be -

(4.92/50) x 100 = 9.84%

Therefore, the percentage of the ethanol in the mixture will be 9.84%.
