ab      ac        bc          40     50       60     4    4    4

c)they are similar because all sides break down to ¾  

Step-by-step explanation: i did this on my test

a) The pairs of proportional triangle is

AB and YZ,

AC and XY,

BC and XZ

b) The fraction of side is

YZ / AB = XY / AC= XZ / BC = 3/4.

c) Yes the similarity of Triangle.

Similar triangles are triangles that have the same shape but differ in size. Similar items include all equilateral triangles and squares with any side length. In other words, if two triangles are identical, their corresponding angles and sides are congruent and in equal proportion. The " sign here denotes the resemblance of triangles.

In Triangle ABC and YZX

a) So, the pairs of proportional triangle is

AB and YZ,

AC and XY,

BC and XZ

b) The fractions with your side pairs is

YZ / AB = 30 / 40 = 3/4

XY / AC = 37.5 / 50 =  3/4

XZ / BC = 45/ 60 = 3/4.

c) As, the ratio of sides are proportion.

So, by SSS similarity criteria the triangles are similar.

Answer:

it may be V ≈ 4191.6 cm3 so sorry if i'm wrong!!!

Step-by-step explanation:

Answer: V ≈ 2514.9 cm3

Step-by-step explanation:

To find the volume of the prism, first calculate the area of the base.

To find the apothem of the hexagonal base, recognize that the sum of the measures of the interior angles in a hexagon is (6−2)⋅180°=720°. So, the interior angle has measure 720°6/=120°.

The base angle of the triangles with the hexagon's sides as their base is one-half of 120°, or 60°. The apothem bisects these triangles to form two right triangles with the short leg length of 5.5 cm.

By the definition of tangent, tan 60°=?/5.5.

Solve for ?.

?=5.5 ⋅ tan 60°

Therefore, the apothem length equals 5.5 ⋅ tan 60°.

The area of a hexagonal base.

B=6⋅(12⋅11⋅?)

Substitute 5.5⋅tan60° for ?.

B=6⋅(12⋅11⋅5.5 ⋅ tan60°)

Simplify.

B=181.5 ⋅ tan60° cm2

The volume of a prism.

V=Bh

Substitute 181.5 ⋅ tan60° for B and 8 for h.

V=(181.5 ⋅ tan60°)⋅8

Multiply 181.5 by 8.

V=1452 ⋅ tan60°

Use a calculator to approximate.

V≈2514.9 cm3

Therefore, the volume of the hexagonal prism is approximately 2514.9 cm3.

Answer:

Your answer would be 11.

Step-by-step explanation:

This is because area = length x width.

16 x 11 = 176 :) Hopefully this helps!

Answer:

x = 11 units.

Step-by-step explanation:

Area = x * 16 = 176

x = 176/16

= 11.

Answer:

The average movie ticket prices in 2020 was $ 10.25.

Step-by-step explanation:

If (0 , 4) and ( 8, 6) are two points on a line, the slope of the line is:

m= y2 - y1/ x2 - x1

m= (6 - 4) / (8 - 0)

m= 1 / 4

The y-intercept is $ 4, meaning it is the average movie ticket price in 1995.

Therefore,

Y = mx + b

Y = 1/4 x + b

It is m= 1/4, interpreting the slope we have that for every additional 4 years the average movie ticket price will increase by $ 1.

The year 2020 is 25 years after 1995, then

Y= 1/4 (25) + 4

Y = $ 10.25

The average movie ticket price was $10.25 in 2020.

Answer:

1/9

Step-by-step explanation:

Subtract them

5/9-4/9=1/9 Answer

Answer:

B, C, D

Step-by-step explanation:

7x + 1 + 105 = 180

7x = 74

x = 74/7

4y + 14 + 7y + 1 = 180

11y = 165

y = 15

m<A = 4y + 14 = 4(15) + 14 = 74°

m<B = 7x + 1 = 7(74/7) + 1 = 75°

m<C = 7y + 1 = 7(15) + 1 = 106°

Well formatted version of question :

Olga tried to solve an equation step by step

1/4(1/3k+9)=6

step 1- 1/3k+9=24

step 2- 1/3k=15

step 3- k=5

find olgas mistake

step 1

step 2

step 3

olga did not make a mistake

Answer:

Step 3

Step-by-step explanation:

Given the equation :

1/4(1/3k+9)=6

Step 1 : Olga multiplied both sides by 4

1/4(1/3k + 9) * 4 = 6* 4

1/3k + 9 = 24

Step 2 : Olga subtracted 9 from sides

1/3k + 9 - 9 = 24 - 9

1/3k = 15

Step 3 : Both sides should be multiplied by 3

1/3k * 3 = 15 * 3

k = 45

This is the step Olga made a mistake. Olga attempted to divide 15/3 = 5 instead of Multiplying 15 * 3 to obtain 45

Answer:

m=-4/3

Step-by-step explanation:

The equation for slope is y2-y1/x2-x1

m=(y2-y1)/(x2-x1)  

m=(12--4)/(1-13)  

m=16/-12

m=-4/3

Since a CAD is 4/5 of a Euro (just for this question) all we needed to do was to multiply 0.8 by 300.

Answer:

-5/2 or -2.5

Step-by-step explanation:

Find the slope using rise over run (y2 - y1) / (x2 - x1)

(y2 - y1) / (x2 - x1)

(33 - 8) / (-16 + 6)

25 / -10

= -5/2

So, the slope is -5/2 or -2.5

Answer:

We know that

Slope

[tex] \bf \: \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]

Where

y2 = 33

y1 = 8

x2 = -16

x1 = -6

33 - 8/-16 - 8

25/-24

Answer:

Midpoint for A is (1,5) and for B it is (2.5,4.5)

Step-by-step explanation:

To get the midpoint you add the x coordinates and divide by 2 and then the y coordinates and divide by 2.

X = (3 + -1)/2    y = (8+ 2)/2

   =2/2 = 1             10/2=5

Answer:

A= 314.16m^{2}

Step-by-step explanation:

if its a half a circle then we use the formula to find area of a circle and get half of it.

[tex]A=\pi r^{2}[/tex]

[tex]A=\pi 10^{2}[/tex]

[tex]A= 314.16m^{2}[/tex]  

Answer:

I think C

so it's kind of a process of elimination you have to see the order of the numbers and what order each number is in so for A you can see that it's 345 is greater than 354 which is inspect cuz 354 is greater than 345 for B that's an obvious answer is is 400 is less than 40 which is obviously wrong because 400 is greater has two zeros and 40 only has one 0 for C it has 4008 is less than 4080which is actually correct if you look at the way that the numbers are written you could see that 80 is greater than 8 D it's obviously not correct because it says 20090 is equal to 23009 which is incorrect because 90 is greater than 9

Answer:

Slope = 3

Y-intercept = -2

Step-by-step explanation:

Points on the line: (0, -2) and (1,1)

Slope:

m=(y2-y1)/(x2-x1)

m=(1+2)/(1-0)

m= 3/1

m = 3

Slope-intercept:

y - y1 = m(x - x1)

y + 2 = 3(x - 0)

y + 2 = 3x

y = 3x - 2

y = mx + b, where

m = slope

b = y-intercept

Answer:

4x^2-21x-18

Step-by-step explanation:

Answer:

the answer 4

Step-by-step explanation:

4 of each because (1.25x4) + (1.50x4) = 11.50

Answer:

Sally bought 6 sodas and 2 cups of coffee.

Step-by-step explanation:

Variable x = number of sodas

Variable y = number of coffees

$1.50x + $1.25y = $11.50

x + y = 8 drinks

$1.50(6) + $1.25(2) = $11.50

$9.00 + $2.50 = $11.50

I simply plugged in numbers that totalled to 8 drinks until I reached $11.50 as the total.

For example:

$1.50(5) + $1.25(3) = $11.50

$7.50 + $3.75 = $11.50

$11.25 = $11.50

This is not correct as they do not equal so this cannot be the answer.
