Answer:

DE = 4cm.

Step-by-step explanation:

The Isoscles Triangle Theorem says that:

"If two sides of a triangle are congruent, then angles opposite those sides are congruent."

The converse of this theorem is

"If angles opposite those sides are congruent, then two sides of a triangle are congruent."

Therefore, since ∠F is congruent to ∠D and are opposite sides ED and EF

while EF = 4 cm and DF = 5 cm.

DE = 4cm.

Answer:

$337.50

Step-by-step explanation:

The computation of the number of miles need to drive for determining the same cost is given below:

Let us assume the miles be x

So for the first plan, the equation is

= $0.90x

And for the second plan, the equation is

= $75 + $0.70x

Now equate this

0.90x = $75 + 0.70x

0.90x - 0.70x = $75

0.20x = $75

x = $75 ÷ 0.20

= 375 miles

Now the same cost would be

For plan A and plan B

0.90x = $75 + 0.70x

0.90(375) = $75 + 0.70(375)

$337.5 = $75 + $262.50

$337.50 = $337.50

Answer:

D

Step-by-step explanation:

The slope always comes before the x, and the y-intercept comes last when in slope intercept form. In this case, you would get y=5x-1/2.

Answer:

0.4

Step-by-step explanation:

You need to divide the 6 by 15 in order to get 0.4.

Ratios, fractions, decimals, and percentages are all pretty much each other, as ratios are just fractions but sideways with the colon in between the numbers. Ratios are to show a relationship, as well as the others. Fractions and ratios are decimals, as you can just simplify them into decimals. Percentages are just decimals but with the decimal moved over to the left twice. So 0.43 becomes 43%.

1.49 becomes 149%

0.00432 becomes 0.432%

Answer:

80 in^2 or 80 square inches

Step-by-step explanation:

Area of the top triangle=

1/2*4*4

8 square inches,

Area of the square=

4*4

16 square inches

Area of the rectangle=

4*8

32 square inches

Area of both bottom triangles=

2(1/2*3*8)

24 square inches

add them up and you get

3x-12y=216

-3x. -3x

-12y=216-3x

÷-12. ÷-12

Y= -18+1/4x

Answer:

Step-by-step explanation:

Coordinates of the vertices of the triangle are,

M(-2, 5), N(3, 2) and L(-2, 1)

Rule for the rotation of a point (x, y) 90° counterclockwise about the origin ,

(x, y) → (-y, x)

That means coordinates of a point (x, y) becomes (-y, x) after the rotation of 90° counterclockwise about the origin.

Following this rule,

M(-2, 5) → M'(-5, -2)

N(3, 2) → N'(-2, 3)

L(-2, 1) → L'(-1, -2)

Now we can draw the image triangle M'N'L' with the help of these image points.

Answer: $3.49

Step-by-step explanation:

Earnings per share shows how much of the profit of the company every share will get.

You can use it to calcutae the P/E ratio through the following formula:

P/E ratio = Share price / Earnings per share

15.17 = 52.93 / EPS

EPS * 15.17 = 52.93

EPS = 52.93 / 15.17

= $3.49

Step-by-step explanation:

8 + 30 + 9 + 3 = 50

8 students will walk.

8/50

Brainlist pls!

Answer:

About 16%

Step-by-step explanation:

Out of the first 50 students surveyed, 8 of them walk to school. 8/50 is equal to 0.16 or 16% of the students asked. Based off of that sample size, that would be the probability of the next student walking to school.

Answer: Section A holds 27500 , Section B has 14100 and SEction C has 13400.

Step-by-step explanation:

Let x= Number of seats in section A.

y = Number of seats in section B.

z= NUmber of seats in sectionC.

As per given , we have

x+y+z=55000           (i)

x= y+z                (ii)

28x+16y+12z=1156400          (iii)

Substitute value of x from (ii) in (i), we get

[tex]x+x=55000\\\\\Rightarrow\ 2x=55000\\\\\Rightarrow\ x=27500[/tex]

From (i)

[tex]27500+y+z=55000\\\\\Rightarrow\ y+z=55000-27500\\\\\Rightarrow\ y+z=27500 \ \ \ (iv)[/tex]

From (iii), we get

[tex]28(27500)+16y+12z=1156400 \\\\\Rightarrow\ 770000+16y+12z=1156400\\\\\Rightarrow\ 16y+12z=386400\\\\\Rightarrow\ 4y+3z=96600 \ \ \ \ (v)[/tex]

Multiply 3 to (iv), we get

[tex]3y+3z=82500\ \ \ \ (vi)[/tex]

Eliminate (v) from (iv), we get

[tex]y=14100[/tex]

from (iv)

[tex]14100+z=27500\\\\\Rightarrow\ z=13400[/tex]

Hence, Section A holds 27500 , Section B has 14100 and SEction C has 13400.
