The pair of triangles that are similar are △DEF ~ △GHI and △JKL ~ △ABC

Given:

△ABC

length = 20

Base = 14

length / base = 20/14

= 10/7

△DEF

length = 10

Base = 8

length / base = 10/8

= 5/4

△GHI

length = 12

Base = 15

length / base = 15/12

= 5/4

△JKL

length = 10

Base = 7

length / base = 10/7

Therefore, the pair of triangles that are similar are △DEF ~ △GHI and △JKL ~ △ABC

Answer:

5th choice) a , c , b

Step-by-step explanation:

Find the last angle measurement. Note that the total angle measurement of the interior angles of a triangle = 180°.

It is given that two of them are 50 & 60. Find the last measurement:

180 - (50 + 60) = 180 - 110 = 70.

Note that to find the sides without proper measurements, the angles OPPOSITE of the sides determine the value. The greater the angle's value, the greater the opposite side's measurement value.

In this case, side a will be the least as it is opposite of 50°, side c will be next as it is opposite of 60°, and side b will be the greatest as it is opposite of 70°.

Step-by-step explanation:

f(x) = -x-2

in finding x we need to implies that we already know f(x) = 12

therefore:

f(x) = -12 - 2

we need to know this laws that - × - is = +

this give us to the final answer:

12 + 2 = 14

Answer:

117.45 in²

Step-by-step explanation:

Given that:

Diameter of circular pizza = 10 inches

Length of square box = 14 inches

Area of a square = a²

Where a = side length

Area of square = 14² = 196 in²

Area of circle :

pi * r²

Pi = 3.142 ; r = d/2 = 10/2 = 5 inches

Area of circle = 3.142 * 5² = 78.55 in²

Amount of the box which is empty :

196 in² - 78.55 in² = 117.45 in²

Answer: t=0.4

Step-by-step explanation: 22t+3t=12-5t

25t=12-5t

30t=12

t=0.4

In this question, we multiply the equation and calculate the value by adding/subtraction, and the further calculation can be defined as follows:

Given:

[tex]\bold{2(11t+1.5t) = 12- 5t}[/tex]

To find:

Solve the equation=?

Solution:

[tex]\to \bold{2(11t+1.5t) = 12- 5t}\\\\\to \bold{22t+3.0t = 12- 5t}\\\\\to \bold{22t+3.0t +5t= 12}\\\\\to \bold{30t= 12}\\\\\to \bold{t= \frac{12}{30}}\\\\\to \bold{t= \frac{4}{10}}\\\\\to \bold{t= 0.4}\\\\[/tex]

Therefore the final answer is "0.4"

Answer:

5/4

Step-by-step explanation:

the equation for slope is:

y² - y¹

m= x² - x¹ , except the ones and twos are at the bottom by the x. if you plug into the equation you get:

-7 - 8

m= 5 - (-7) = 5 + 7. that equation equals

-15. 5

m = 12 = 4

Slope of the line passing through the points (-7, 8) and (5, -7) is  [tex]\frac{-5}{4}[/tex]

The slope of a straight line between two points says ([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex], [tex]y_{2}[/tex])can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter 'm'.

As we know that slope of line (m)  passing through ([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex], [tex]y_{2}[/tex]) is given as

m = [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

As the line passing through the points (-7, 8) and (5, -7)

m = [tex]\frac{-7-8}{5-(-7)}[/tex]

m = [tex]\frac{-15}{12}[/tex]

m = [tex]\frac{-5}{4}[/tex]

Hence, slope of the line passing through the points (-7, 8) and (5, -7) is  [tex]\frac{-5}{4}[/tex]

m=9--8/-7--8= 16/15

y-b=m(x-a)

y--8=16/15(x--8)

y+8=16/15(x+8)

Answer:

So, first you need to set up a proportion and cross multiply. This allows you to  get an equation which you can solve for x.

Step-by-step explanation:

[tex]\frac{4}{5}[/tex] × [tex]\frac{17}{x}[/tex]  

Cross multiply to get 4x = 85

Next, isolate the x variable by dividing the 4 on both sides. This leaves you with x = 21.25.
