A.30:50
B.21:28
C:15:28
D.9:15

Answers

Answer 1

Answer:

B.

Step-by-step explanation:

Since 21 is divided by 3 you might think that it is equivalent but remeber you have to divide by both sides, so if you divide 21 by 7 it works but 28 by seven does not! Hope this helps!

Miss Allen read for 3/4 of an hour less than the student who read the most. How long sis Miss Allen read for?

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Allen = \frac{3}{4}hr[/tex] less than the most hour

Required

Hours read by Miss Allen

The question is incomplete, as the hours read by each student is not given.

To solve this, I will assume that the longest hours read by a student is x.

So, the expression for Miss Allen will be:

[tex]Allen = x - \frac{3}{4}hr[/tex]

Assume that [tex]x = 1hr[/tex]

The expression becomes

[tex]Allen = 1hr - \frac{3}{4}hr[/tex]

Take LCM and solve

[tex]Allen =\frac{4 - 3}{4}hr[/tex]

[tex]Allen =\frac{1}{4}hr[/tex]

A fair spinner has 10 equal sections: 3 red, 3 blue and 4 green. It is spun twice. What is the probability of getting not green then green?

Answers

Answer:

0.24

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome. The probability that an even will happen or not happen is 1.

Given that the spun has 10 sections 3 red, 3 blue and 4 green, the probability of not getting green

= (3 + 3)/(3 + 3 + 4)

= 6/10

The probability of getting green

= 4/10

Hence the probability of getting not green then green

= 6/10 * 4/10

= 24/100

= 0.24

The expression shown is the cost a customer pays for an item,where c is the cost the store pays for the item and 0.85c is the 85% price increase the store adds to the item. Which expression is equivalent to c+0.85c

Answers

Answer:

D. 1.85c

Step-by-step explanation:

The expression shown is the cost a custom pays for an item, where c is the cost the store which expression is equivalent c+0.85c?

A. 0.15c B. 0.85c C. 1.15c D. 1.85c

Given:

c + 0.85c

c standing alone has a coefficients of 1

The coefficients of 0.85c is 0.85

The two terms have the same variable c

Add both terms together

c + 0.85c

= 1.85c

Therefore,

c + 0.85c = 1.85c

D. 1.85c

The radius of a circle is 8 meters. What is the length of a 180° arc?

Answers

Answer: 8 meters

Explanation:

Calculate arc length of 180 degree

Formula: arc length = 2 x pi x r x ø/360°

pi = 3.14
r = 8m
Ø = 180°

=> Arc length = 2 x 3.14 x 8 x 180°/360°
Arc length = 2 x 3.14 x 8 x 1/2
Arc length = 3.14 x 8
Arc length = 25.12meters
