Triangle ABC Is Similar To Triangle DEF. What Is The Value Of X ?

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AC}{DF}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values

[tex]\frac{45}{x+8}[/tex] = [tex]\frac{30}{25}[/tex] ( cross- multiply )

30(x + 8) = 1125 ( divide both sides by 30 )

x + 8 = 37.5 ( subtract 8 from both sides )

x = 29.5 → A

Whats the area of the rectangle?
Length: 2 1/7
width: 3 1/3

I dont need an explanation just the simplified answer

Answers

Answer:

The area of rectangle is "31 units²".

Step-by-step explanation:

The given values are:

Length of rectangle,

= [tex]\frac{21}{7}[/tex]

Width of rectangle,

= [tex]\frac{31}{3}[/tex]

As we know,

The area of rectangle is:

=  [tex]Length\times width[/tex]

On substituting the values, we get

=  [tex]\frac{21}{7}\times \frac{31}{3}[/tex]

=  [tex]\frac{217}{7}[/tex]

=  [tex]31 \ units^2[/tex]

ok ik but i need help with this i think i got it tho -275=2x -50

Answers

Answer:

-112.5

Step-by-step explanation:

2x - 50 = -275

2x = -225

x = - 112.5

Answer:

x = -225/2 (or) -112.5

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ -275 = 2x - 50

Then the value of x will be,

→ -275 = 2x - 50

→ 2x - 50 = -275

→ 2x = -275 + 50

→ 2x = -225

→ x = -225/2

→ [ x = -112.5 ]

Hence, value of x is -112.5.

Three of the paths in a city park form a right triangle, as shown on the map. Each unit on the map represents 10 meters. The city plans to plant trees along these paths.

Answers

The perimeter of the triangle is 188.1 m

How to find the perimeter of the triangle?

The perimeter of a triangle can be determined by adding the three lengths of the triangle.

From the image, the coordinates of vertices of the triangle are:

(-3, 3), (-3, -2) and (3, 3)

distance between (-3, 3) and (-3, -2) is:

3-(-2) = 5  (we use y coordinates only because x are the same)

       = 50 m  (Each unit on the map represents 10 meters)

distance between (-3, 3) and (3, 3) is:

3-(-3) = 6    (we use x coordinates only because y are the same)

       = 60 m

distance between (3, 3) and (-3, -2) is:

= √(50² + 60²)     (Pythagoras)

= 78. 1 m

Perimeter = 50 + 60 + 78.1 = 188.1 m

(08.03 MC) The dot plot below shows the hourly rate of some babysitters in a city: Which statement best describes the shape of the data? (1 point) Question 7 options: 1) It is symmetric and has no gaps. 2) It is not symmetric and has a peak at $5.00. 3) It is a cluster from $1.00 to $5.00 and has gaps. 4) It is a cluster from $1.00 to $5.00 and has a peak at $5.00.

Answers

Answer:

A. It is symmetric and has no gaps.

Step-by-step explanation:

Given

See attachment for dot plot

Required

Select the true statement

From the attached plot, we can see that

The plot is bell shaped (by tracing the number of dots on each dataset) There is no gap between each dataset (from 4 to 7)

Since (1) all bell shaped distribution are symmetric and (2) there is no gap between the dataset, then (a) is correct.

The spinner is shown has eight congruent sides the spinner is spun 200 times. What is a reasonable prediction for the number of times the spinner will land on 2 or 3

Answers

Answer:

50 times

Step-by-step explanation:

Total number of faces = total possible outcomes = 8

Number of 2 or 3 on spinner = required outcome = 2

Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes

P(2 or 3) = 2 / 8 = 1/ 4

From 200 ; prediction for the number of 2 or 3

1/4 * 200
