Answer:

80%

Step-by-step explanation:

% is out of 100 so make the denominator of 4/5 to be 100:

4/5 times 20/20 = 80/100 = 80%

Answer:

80%

Step-by-step explanation:

4 divided by 5 equal .8

.8 x 100 equals 80

It's multiplied by 100 because usually percentages are out of 100.

OR

You can move the decimal in .8 to 2 space to the right

Step-by-step explanation:

In ΔACE & ΔBCD,

   ∠A ≅ ∠B      {Given}     Angle

  AC = BC           {Given}    Side

  ∠ACE = ∠BCD    { Reflexive property} Angle

ΔACE ≅ ΔBCD      ------>A S A Property

Since its 10^-3, the decimal point moves to the left 3 times. hope this helped :)

Answer:

x=4

Step-by-step explanation:

It's a parallel line so the equation is

100+19x+4=180

19x=180-100-4

19x=76

x=76/19

x=4

Answer: x = 4

Step-by-step explanation: The 2 angles are same-side interior angles, which are supplementary, and supplementary angles add up to 180, so we know that 19x + 4 = 80.

- 4. -4

19x = 76

/19. /19

X = 4

Step-by-step explanation:

C=r^2(3.14)

C=d(3.14)

78.8/3.14=d

Square root diameter to get radius.

Answer:

x intercept: 10, y intercept: -8

Step-by-step explanation:

make into y = mx + b

4x = 5y + 40

4x - 40 = 5y

y = 4/5x - 8

plug in 0 for x, to find y intercept

y = -8

plug in 0 for y, to find x intercept

0 = 4/5x - 8, x = 10

Answer:

The indifference point is 200 miles

Step-by-step explanation:

First, we need to establish the total cost formula for each company:

Pack and Go:

Total cost= 39.95 + 0.45x

x= miles driven

U-Drive:

Total cost= 59.95 + 0.35x

x= miles driven

Now, we equal both formulas and isolate x:

39.95 + 0.45x = 59.95 + 0.35x

0.1x = 20

x= 200 miles

The indifference point is 200 miles

Answer:

A is answer 1/ 39.95 + .45x = 59.95 + .35x

B is answer 3/ miles driven

C is 3 /200

Step-by-step explanation:

Step-by-step explanation:

Answer:

April took out a loan of $600 and paid it back with simple interest of $60 after 5 years. The formula to calculate interest is  given the principal  and the time   and the interest rate  is . For this problem we have to find the interest rate   given  . To archive that , we can just solve the equation making the interest rate the subject of the formula as shown below,

I= Prt

=> r= I/Pt

=> r= 60/600x5 = 1/50

The interest rate is 1/50 or 0.02 as a decimal. The interest rate is 2% as a percentage.

Answer:

25.) Slope of AB = 5

Slope of CD = -1/5

Perpendicular

26.) Slope of EF = -3/5

Slope of GH = -3/5

Parallel

Step-by-step explanation:

Use this formula to find slope. [tex]\frac{y2 - y1}{x2 - x1}[/tex]

Parallel lines have the same slope

Perpendicular lines have the opposite reciprocal and sign

25.)

Plug in AB slope is 5

2 - 7/ 3 - 4 = -5/-1 = 5

Plug in for CD slope is -1/5

3 - 4/ 2 - -3 = -1/5 = -1/5

The lines AB and CD are perpendicular because they have opposite reciprocals and opposite signs.

26.)

Plug in EF slope is -3/5

1 - 4/ 3 - -2 = -3/5 = -3/5

Plug in GH slope is -3/5

-5 - -2/ 4 - -1 =  -3/5 = -3/5

The lines EF and GH are parallel lines because they have the same slopes.

Hope this helps ya!

Answer: 7238.28

Step-by-step explanation:

Answer:

Number of students who do not know = 24

Step-by-step explanation:

Year II students = 240

15% of the students want to go to college.

Number of year II students who wants to go to college = 15% of 240

= 15/100 × 240

= 0.15 × 240

= 36

¾ of the students want to stay at school.

Number of students who wants to stay at the school = 3/4 × 240

= (3 × 240) / 4

= 720 / 4

= 180

Number of students who do not know = Total year II students - Number of year II students who wants to go to college - Number of students who wants to stay at the school

= 240 - 36 - 180

= 24

Number of students who do not know = 24

Answer:

Hiiiiiii
