26. An electronic game store is offering a 20% discount on all items in the store.
If the original price of a game is $55, how much will it cost after the discount?
Answer:
11$
Step-by-step explanation:
20% is equivalent to 0.20, so if we multiply that by 55, it will take off 20% of the price, giving us 11$.
0.20 × 55 = 11

The triangles are similar.
What is the value of x?
Answer: The answer is 13, read on to find out
Step-by-step explanation: The traingles are simliar so the values are similar as well. Find a lowest common factor of the values.
The lowest common factor is 4 because all the numbers can be divided by the number 4.
20 divided by 4 is 5 which is already shown on the graph
48 divided by 4 is 12
All we have to do now is 52 divided by 4

Answer:
x = 14.14 and y = 10
Step-by-step explanation:
Using trigonometric ratios;
10/x = cos 45
x = 10/(cos 45)
x = 14.14
y/10 = tan 45
y = 10 * tan 45
y = 10

A right triangle has legs measuring 18 in. and 26 in.
What is the length of the hypotenuse?
Round to the nearest tenth.
18.8 in.
31.6 in.
44.0 in.
100.0 in.
i know the answer but I need someone to explain to me how to do this, I do a^2+b^2 +c^ and i keep getting 26
Answer:
The answer is 100 in
Step-by-step explanation:
The pythagorean theorm states that, for any right triangle where a and b are the legs and c is the hypotenuse, a^2 + b^2 = c^2. So, we can substitute and solve.
18^2 + 26^ 2 = c^2
324 + 676 = c^2
1000=c^2
Square root of 1000 = c
100.0=c

jacobs paints the outside of the rectangular primsim below, except for thr bottom the length is 9 cm and the width is 4/3. What is the total area that he paints?
Answer:
the area of triangle formula is A = B*H / 2
so it means 16 square = (x+4) x /2
so x²+4x -32=0, D' = 2²- (-32)= 36, sqrt of D' = 6
so x = -2 -6 = -8 or x= -2 +6 = 4
x must be positive so x = 4

Find the area of the figure
A: 14 cm2
B: 50 cm2
C: 60 cm2
D: 64 cm2
Answer:
64 cm^2
Step-by-step explanation:
Split the figure into two parts (top and bottom rectangle)
TR : 2 x (12-5)*
2 x 7 = 14
*= Since there are a few ways to split it up but I chose to make the top one shorter so you have to subtract 5 from 12
BR : 10x5 = 50
Add together
14 + 50 =
64 cm^2
Hope this helps :)

A parallelogram has an area of 10square feet.
a.Complete the table that shows the relationship between the dilated area ( ) and
the scale factor ( y).
All answers are listed below:
For A = 0 ft², the scale factor is 0.For A = 40 ft², the scale factor is 2.For A = 160 ft², the scale factor is 4.For A = 360 ft², the scale factor is 6.For A = 640 ft², the scale factor is 8.How to determine the dilated area of a parallelogram
The area of the parallelogram (A), in square feet, is equal to the product of the base (b) and the height (h), both in feet. By applying the rigid transformation of dilation on each side, we have the following formula:
A = k² · b · h (1)
Where k is the scale factor.
And we can derive a scale factor by comparing two areas:
[tex]k = \sqrt{\frac{A}{A_{o}} }[/tex] (2)
Where [tex]A_{o}[/tex] is the original area, in square feet.
If we know that [tex]A_{o} = 10\,ft^{2}[/tex], then the scales factors are shown below:
For A = 0 ft², the scale factor is 0.
For A = 40 ft², the scale factor is 2.
For A = 160 ft², the scale factor is 4.
For A = 360 ft², the scale factor is 6.
For A = 640 ft², the scale factor is 8.

Answer:
x = 1
Step-by-step explanation:
Using Definition of Logarithm
7 ^(4x−6) = 1/49
Use the rules of exponents and logarithms to solve the equation.
7 ^(4x−6) = 1/49
Take the logarithm of both sides of the equation.
log(7^4x-6) = log(1/49)
The logarithm of a number raised to a power is the power times the logarithm of the number.
(4x-6)log(7) = log(1/49)
Divide both sides by log(7).
4x-6 = log(1/49)/log(7)
By the change-of-base formula log(a)/log(b) = log(small b under) (a).
4x-6 = log(small 7 under) (1/49)
Add 6 to both sides of the equation.
4x=−2−(−6)
Divide both sides by 4.
x = 4/4 which is the same as x = 1

A. 4.69 pounds
B. 8.88 pounds
C. 18.75 pounds
D. 75.00 pounds
The weight of sand in the mixture when the weight of the clay in the mixture is 6.25 pounds is 4.69 pounds.
The equation can be represented as follows:
3c = 4s
How to find the variable in an equation?3c = 4s
where
c = weight of the clay in the mixtures = weight of sand in the mixtureHence,
3c = 4s
4s = 3c
let's make s the subject of the formula, since, we want to find s when c = 6.25 pounds
s = 3 / 4 c

Find measure of the angle UTW
Step-by-step explanation:
Since radii of a circle are congruent, UT is congruent to WT.
Since angles opposite congruent sides in a triangle are congruent, angles UWT and WUT are congruent.
This means the measure of UTV is 180-57-57=66 degrees
A graph shows the preimage and image of a shape that has undergone one transformation. If the preimage and image are not congruent what transformation was applied?
A. reflection
B. rotation
C. dilation
D. translation
Answer:
C. dialtion
Step-by-step explanation:
A dialtion either reduces or enlarges the dimensions of a shape, causing for them to no longer be congruent.
A reflection wouldn't change the congruency of the shape since it is just reflecting it across whatever axis. The dimensions stay the same.
A rotation would simply rotate/turn the shape. The dimensions would not be changed.
A translation would slide the shape elsewhere whether it be vertically, horizontally, or diagonally. The dimensions would not change.
Therefore, we can conclude that option C makes the most sense.

Answer:
For all of these triangles apply the formula;
A = BH x 1/2
Where 'B' represents the base, 'H' stands for the height, and 1/2 just means to divide the product of the two lengths (base x height) by 2.
1.
Base = 9.1
Height = 31.2
Plug into formula:
A = BH x 1/2
A = 9.1(31.2) x 1/2
A = 283.92 x 1/2
A = 283.92/2
A = 141.96 square centimetres.
2.
Base = 5
Height = 3 3/4 which can be considered 3.75
Plug into formula:
A = BH x 1/2
A = 5(3.75) x 1/2
A = 18.75 x 1/2
A = 18.75/2
A = 9.375 square kilometres.
3.
Base = 2.4
Height = 3.2
Plug into formula:
A = BH x 1/2
A = 2.4(3.2) x 1/2
A = 7.68 x 1/2
A = 7.68/2
A = 3.84 square inches.
4.
Base = 11
Height = 60
Plug into formula:
A = BH x 1/2
A = 11(60) x 1/2
A = 660 x 1/2
A = 660/2
A = 330 square millimetres.
5.
Base = 10
Height = 13 1/2 which can be considered 13.5
Plug into formula:
A = BH x 1/2
A = 10(13.5) x 1/2
A = 135 x 1/2
A = 135/2
A = 67.5 square feet.
Answer:
1. 141.96 cm²
2. 9⅜ km²
3. 3.84 in
4. 10.39mm
5. 66.67 ft
Step-by-step explanation:
Formula of Area of Triangle : ½ × base × height
1. = ½ × 9.1 × 31.2
= 9.1 × 15.6
= 141.96 cm²
2. = ½ × 3¾ × 5
= ½ × 15/4 × 5
= 15/8 × 5
= 75/8 = 9⅜ km²
3. = ½ × 3.2 × 2.4
= 3.84 in
4. = tan c = AB/BC
c = tan -¹ (AB/BC)
c = tan -¹ (60/11)
c = 79.61
A = 90 - 79.61 = 10.39mm
5. = ½ × 13⅓ × 10ft
= 66.666 ≈ 66.67 ft

A triangle has side lengths of (5n+3p)(5n+3p) centimeters, (9n+8q)(9n+8q) centimeters, and (6q+9p)(6q+9p) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
The expression that represents the perimeter of the given triangle in centimeters is; 14n + 10p + 14q
What is the perimeter of the triangle?We are given the side lengths of the triangle as;
5n + p; 9n + 8q; 6q + 9p
Now, the formula for perimeter of a triangle is;
Perimeter = a + b + c
where a, b and c are side lengths of the triangle. Thus;
Perimeter = 5n + p + 9n + 8q + 6q + 9p
Perimeter = 14n + 10p + 14q
In conclusion, we can sa that the perimeter of the given triangle is 14n + 10p + 14q.
