The larger triangle is a dilation of the smaller triangle with a center of dilation at (1,−1)
What is the scale factor of the dilation? No Links and brainlest
18
14
4
8
Answer:
Scale factor = 4
Step-by-step explanation:
Scale factor = [tex]\frac{\text{Dimension of the larger (Image) triangle}}{\text{Dimension of the smaller (Preimage) triangle}}[/tex]
From the given triangle,
Length of one side of the larger triangle = 8 units
Length of the corresponding side of the smaller triangle = 2 units
By substituting the values in the formula of scale factor,
Scale factor = [tex]\frac{8}{2}[/tex]
Scale factor = 4
. Visually compare the dot plot of heights of field hockey players to the dot plots for softball and basketball players. Shape: Center: Spread:
Answer:
Kindly check explanation
Step-by-step explanation:
Using visual comparison :
SHAPE :
Both plots are fairly left skewed as their peaks are more shifted to the right and tails to the left of the distribution.
The centre :
Both softball and basketball plots are centered around the median of the distribution. With softball having a centre (median value) of 5'4'' and basketball has a value of 5'8''.
Spread :
The softball plot spread from 4'9'' through 5'6''
While basketball spreads from 5'2'' through 6'0''

Sarah downloaded two apps which were 7.48 kb total. If one app was 4.78 kb, how big was the other app?
Answer:
2.7 kb
Step-by-step explanation:
Total kb = 7.48
Total apps = 2
one app = 4.78
another app = x
> 4.78 + x = 7.48
x = 7.48 – 4.78
= 2.7 kb

Please help meee! (Solve area)
Answer:
First we can do (12*4)- thats the top rectangle. Remember area is base times height.
48
Next lets do (8*12)-thats the middle rectangle
48+ 96
Now the triangles.
you can just do 2*8/2 because a triangle is half of a rectangle.
48+ 96+ 8
add 8 again because theres 2 triangles-
48+96 + 8 +8
Your answer is 160
I hope this helps you!
Goodluck!

A bridge is supported by triangular braces. If the sides of each brace have lengths 63 feet, 46 feet, and 40 feet, find the measure of the angle opposite the 46 foot side. Round to the nearest degree.
Given:
The sides of each brace have lengths 63 feet, 46 feet, and 40 feet.
To find:
The measure of the angle opposite the 46 foot side.
Solution:
According to the Law of Cosines:
[tex]\cos A=\dfrac{b^2+c^2-a^2}{2bc}[/tex]
We need to find the measure of the angle opposite the 46 foot side. So, [tex]a=46[/tex] and the other sides are [tex]b=63,c=40[/tex].
[tex]\cos A=\dfrac{(63)^2+(40)^2-(46)^2}{2(63)(40)}[/tex]
[tex]\cos A=\dfrac{3969 +1600-2116}{5040}[/tex]
[tex]\cos A=\dfrac{3453}{5040}[/tex]
[tex]\cos A=\dfrac{1151}{1680}[/tex]
Taking cos inverse on both sides, we get
[tex]A=\cos^{-1}\dfrac{1151}{1680}[/tex]
[tex]A=46.75503[/tex]
[tex]A\approx 47[/tex]
Therefore, the measure of the angle opposite the 46 foot side is 47 degrees.

Use the distributive property to expand (simplify) 12(a-5)
Answer:
12a-60
Step-by-step explanation:
12(a-5)
=12a-12*5
Multiply 12 *5=60
=12a-60
Answered by NONE other than the ONE & ONLY #QUEEN herself aka #DRIPPQUEENMO!!!
HOPE THIS HELPED!!!
Answer:
[tex]\huge\boxed{\boxed{12a-60}}[/tex]
Step-by-step explanation:
Hello.
The Distributive Property states that
a(b+c)=ab+ac
Where
a, b, and c can be either constants or variables
we distribute a by multiplying it times b and c, and simplify if necessary.
In this case, we should distribute 12:
12(a-5)
12 times a and 12 times (-5):
12a-60
And we're done!
I hope it helps & have an outstanding day!

Finding angle measures between intersecting lines
Answer:
x = 47°
Step-by-step explanation:
From the picture attached,
CPD is a straight line.
Therefore, ∠CPB and ∠DPB is a linear pair of angles.
And linear pair of angles are supplementary.
By the property of linear pair of angles,
m∠CPB + m∠DPB = 180°
133 + x = 180
x = 180 - 133
x = 47°

a box contains 18 blue flashlights 3 red flashlights 7 silver flashlights ans 2 black flashlights. the flashlights are identical in size and shape. if one flashlight is chosen at random what is the probability that the flashlight will be either blue or black?
Answer:
The answer is 20/30 or in simplified form 2/3
Step-by-step explanation:
The way I do it is I take the probability of blue flashlights, 18/30, added to the probability of black flashlights, 2/30. Then, you simplify by dividing both numbers by 10.

The school orchestra sells carnations on Valentine's Day for $2 each. They buy the carnations that they sell from a local florist for $0.50 each plus a one-time $18 delivery charge. Write a system of equations that describes this situation and solve it using your preferred method.
Answer:
2x - (0.50x + 18) = profit
Step-by-step explanation:
x = number of carnations, for example if 3 carnations were sold, $6 from sales - (1.50 + 18) = profit. The 50 cents from each carnation that they bought to sell, plus 18 delviery fee. Hope this helped! Good luck!

A data set has a mean of 7, a median of 5, and a mode of 8. Which of the numbers (7, 5, or 8) must be in the data set?
7
5
8
Answer:
8 has to be included in the data set. Since 8 is the mode, and the mode is the number that is seen the most in a set of numbers, 8 has to be in the data set for it to be the mode. Therefore, the answer is 8.
