Reviewrship10These figures are similar. The area ofone is given. Find the area of the other.Help ResourcesArea = 100 in.2ㅁ nSkip8 in.10 in.[? ] in.2Enter
SOLUTION:
Step 1:
Since the two figures are similar, it means that they have properties in common.
Step 2:
In the bigger figure, the side given is 10in and its area is 100 square inches meaning (10 in x 10 in).
Step 3:
In the smaller figure, the side given is 8in, and from step 1, we can see that the two figures are similar, so the area of the smaller figure will be (8 in x 8 in) = 64 square inches.
CONCLUSION:
The area of the smaller figure is 8in x 8in = 64 square inches

step 1
Find the unit rate
divide the total miles by the total gallons of gas
so
476/14=34 miles/gal
Let
y ------> the distance in miles
x -----> the number of gal
we have that
the linear equation is equal to
y=34x
part 2
If y=578 miles
Find the value of x
substitute in the equation
578=34x
solve for x
x=578/34
x=17 gallons
find the circumference and area of the circle round to the nearest whole number
Here, we want to find the circumfrence and area of the circle
To find either of this, we need the value of the radius of the circle
The radius of a circle is the distance btetween the center of the circle and the circumfrence of the circle. In this question, this distance is 20 ft
Mathematically, we can calculate the area with the formula;
[tex]\begin{gathered} A\text{ = }\pi\text{ }\times r^2 \\ A\text{ = }\frac{22}{7}\text{ }\times20^2 \\ \\ A\text{ = }\frac{22\text{ }\times\text{ 400}}{7} \\ \\ A\text{ = 1257.1429} \\ \\ A=1257ft^2\text{ to the nearest whole number} \end{gathered}[/tex]To calculate the circumfrence of the circle, we use the formula below;
[tex]\begin{gathered} C\text{ = 2 }\times\text{ }\pi\text{ }\times\text{ r} \\ \\ C\text{ = 2 }\times\text{ }\frac{22}{7}\text{ }\times\text{ 20} \\ \\ C\text{ = }\frac{880}{7} \\ \\ C\text{ = 125.71} \\ \\ C\text{ = 126 ft to the nearest whole number} \end{gathered}[/tex]In the diagram,ABCD is a rectangular wall that casts a shadow CDEF, on the ground. The wall has a height of 4 feet. The shadow is a parallelogram that has a height, FG, that is twice the height of the wall. If the area of the wall is 29.2 square feet, find the area of the shadow.
We know that the height of the rectangular shape is BC=AD= 4 feet and the the area is A=29.2 ft^2. Since the area of our rectangle is given by
[tex]A=(DC)\times(BC)[/tex]we get
[tex]29.2=DC\times4[/tex]By moving the number 4 to the left hand side, we have
[tex]\begin{gathered} \frac{29.2}{4}=DC \\ \text{then} \\ DC=7.3 \end{gathered}[/tex]which also is the lenght of one side of our parallelogram.
Now, the area of our parallelogram is given by
[tex]A_P=\text{base}\times height[/tex]where the base is given by segment DC=7.3 ft and the height FG=2 BC. Then, we get
[tex]\begin{gathered} A_P=DC\times FG \\ A_P=DC\times2BC \end{gathered}[/tex]by substituting our previous result and BC=4 ft, we obtain
[tex]\begin{gathered} A_P=7.3\times2(4) \\ A_P=7.3\times8 \\ A_P=58.4ft^2 \end{gathered}[/tex]Then, the answer is 58.4 ft^2

What is the distance between two points?Let one point be (x, y) and another point be (h, k). Then the distance between the points will be
D² = (x - h)² + (y - k)²
Two companions drive off this way and from a similar spot. One travels North at 40 miles each hour, while different travels East at 25 miles each hour.
The equation for the distance between the friends after t hours is given as,
Let the x-axis as east and the y-axis as north. Then the coordinate after t hours will be (25t, 0) and (0, 40t). Then the distance between them is given as,
D² = (25t - 0)² + (0 - 40t)²
D² = 625t² + 1600t²

Lyle uses a streaming service to watch movies. Last month he paid $26.91 and watched 9 movies. If he watches 11 movies this month, how much will he pay the steaming service?
A. $32.89
B. $26.91
C. $2.99
D. 3.68
Answer:
A. $32.89
Step-by-step explanation:
Take the amount and divide by the number of movies watched
26.91 / 9 =2.99
Now multiply by the new number of movies he wants to watch, 11
2,99 *11
32.89
Answer:
A) $32.89
Step-by-step explanation:
We divided 26.91 by 9 to find how much it is per movie
26.91/9
2.99
It is 2.99 for 1 movie so now we multiply by 11 to find all 11 movies price
2.99x11

The area A of a portion of a circle is:

[tex]38=\pi\cdot r^2\cdot\frac{1}{2\pi}\cdot\frac{7}{5}\pi[/tex]We can cancel the pi on the left of 'r' with the one on the right (the one that's dividing):
[tex]38=r^2\cdot\frac{7\pi}{2\cdot5}[/tex]So, now we clear 'r':

The area of a triangle is 40
the length is x+4 and the height is x
what is the value of x
Answer:
16
Step-by-step explanation:
Area of a triangle = 1/2(b×h)
b or l = x+4
h = x
a = 40
1/2(x+4 × x) = 40
1/2(x+4 × x) = 40x + 4 × x / 2 = 40
4 × x = 4x
4x + x = 5x
5x/2 = 40
cross-multiply
40 × 2 = 5x
40 × 2 = 5x80 = 5x
divide both sides by 5
5x/5 = 80/5
5x/5 = 80/5x = 16

It is stretched horizontally by a factor of 2 and translated up 3 units.
It is compressed horizontally by a factor of 2 and translated up 3 units.
It is stretched vertically by a factor of 2 and translated up 3 units.
It is compressed vertically by a factor of 2 and translated up 3 units.
The correct option B. It is compressed horizontally by a factor of 2 and translated up 3 units.
What is meant by the term translation?The translated shapes appear to be the same size as that of the original shape, and thus the shapes are congruent. They were simply shifted in one or even more directions. There isn't any change in the form because it is simply moved from one location to another.For the given question;
The image function is defined as ; y = ㏒(2x) + 3
The parent function is; y = ㏒(x).
The first graph, X, is multiplied by 2 (2x), compressing it horizontally by a factor of 2.The number 3 is then added, which moves the graph up three units.Thus, the image function y = ㏒(2x) + 3 is obtained by the process as,compressed horizontally by a factor of 2 and translated up 3 units.

Step-by-step explanation:
the image of the point (-9, 9)under a translation is (-5, 13). find the coordinates of the image of the point (-6, "-7)" under the same translation.
The coordinates of the image of the point (-6, -7) after translation is (-20,-3).
What are coordinates?a pair of figures used to specify a point's location on a coordinate plane using the horizontal and vertical separations from the two reference axes. They are typically expressed by the x-value and y-value pair (x,y). Always, the x-coordinate comes before the y-coordinate.
An ordered group of numbers known as coordinates is used to specify a point's location. In the event that the point is on a plane, two numbers are used.
The horizontal and vertical addresses of a point in any two-dimensional (2D) space, such as a sheet of paper or a computer display screen, are called the X and Y coordinates, respectively. These coordinates work as a pair to pinpoint a point's precise location.
A point located at (x,y), translated by (a,b) maps to the point (x+a,y+b).
If we know the location of the point (x,y) and the location of its image (x',y'), we can know the values of (a,b) by subtracting:
(a,b) = (x',y') - (x,y)
We know the coordinates of the point (9,9) and the coordinates of its image (-5,13). Calculate the translation:
(a,b) = (-5,13) - (9,9) = (-14,4)
If the point (-6,-7) is translated under the same conditions, then it will map to the point (-6,-7) + (-14,4) = (-20,-3).
The coordinates of the image are (-20,-3)
