C
[tex]4 \ \frac{1}{2} [/tex]

D
[tex]2 \ \frac{1}{4} [/tex]

Answers

Answer:

D. 2 1/4

Step-by-step explanation:

3/4 inch = 8 feet

24 divided by 8 = 3

(meaning you would multiply eight three times in order to get to 24)

So....

3/4 x 3 = 2 1/4

Answer: 2 1/4

Hope this helps :)

Answer: D - 2 1/4”

Step-by-step explanation:

8 feet goes into 24 feet 3 times

Eg. 24/8 = 3

If 3/4” = 8 feet, then 3 x 3/4” = 24 feet

3 x 3/4” = 2 1/4”

C) neither even nor odd

Answers

Answer:

B is correct option

Step-by-step explanation:

The graph of an even function is symmetric about the y-axis. The graph of an odd function is symmetric about the x-axis. It is possible that the use of these two words originated with the observation that the graph of a polynomial function in which all variables are to an even power is symmetric about the y -axis.

WHAT IS THE LENGTH OF AC? ROUND TO ONE DECIMAL PLACE. DONT HAVE TO SHOW WORK​ helpppp

Answers

Answer:

AC ≈ 5.5

Step-by-step explanation:

Angle bisector theorem states that "angle bisector of an angle divides the opposite side into two segments which are proportional to the other two sides of the triangle."

By applying this theorem in the given ΔABC,

AD is the angle bisector of ∠CAB which divides the opposite side of the angle into two segments BD and CD.

Therefore, [tex]\frac{AB}{BD}=\frac{AC}{CD}[/tex]

[tex]\frac{5.1}{4}=\frac{AC}{4.3}[/tex]

[tex]AC=\frac{5.1\times 4.3}{4}[/tex]

AC = 5.4825

AC ≈ 5.5 units

Angle ABC and angle CBD or a complementary what is the value of X

Answers

Answer:

26degrees

Step-by-step explanation:

Find the diagram attached

From the diagram, Angle ABC and angle CBD are complementary hence;

<ABC + <CBD = 90

Given

<ABC = 2x

<CBD = 38

Substitute

2x + 38 = 90

2x = 90 - 38

2x = 52

x = 52/2

x = 26degrees

Hence the value of x is 26degrees

In a spot check of cartons of eggs, Matilda found that 6 out of 200 eggs were cracked.

In 200 eggs cracked =6

in 1 egg cracked =[tex]\dfrac{6}{200}[/tex]

According to the question,

If the store has 3,000 eggs for sale, how many can expect to be cracked.

In 3000 eggs cracked=[tex]\dfrac{6}{200}×3000[/tex]

90 eggs

Therefore:-

If the store has 3,000 eggs for sale, 90 eggs can expect to be cracked

If the store has 3,000 eggs for sale, 90 eggs can expect to be cracked.

What is Proportion?

A proportion is an equation in which two ratios are set equal to each other.

For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4)

Given that :

In a spot check of cartons of eggs, Matilda found that 6 out of 200 eggs were cracked.

In 200 eggs cracked = 6 / 200 in 1 egg cracked

According to the question,

If the store has 3,000 eggs for sale, how many can expect to be cracked.

In 3000 eggs cracked = 6 / 200 x 3000

= 90 eggs

Hence, If the store has 3,000 eggs for sale, 90 eggs can expect to be cracked.

A tree is 15 feet tall and casts a shadow of 9 feet. How long is the shadow of a tree 25 feet tall?

Answers

I’m not sure if this is right but I would try to think of the question as a ratio. 15ft casts a 9ft shadow (15:9). But u want to find out the length of the shadow when the tree is 25ft. The initial ratio can be divided by 3 (5:3) this makes it easier to get the 25ft tree and it’s shadow equivalent. 25/5=5 so a 25ft would cast a 15ft shadow

Answer:15ft shadow

Answer:

The shadow is 15 feet long.

Step-by-step explanation:

This is a proportion question.  Build a proportion using two fractions.

Angle a and b are supplementary angles, and a is x-3 and b is x+14 what are the measures of angle a and b

Answers

Answer:

a = 81.5

b = 98.5

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

a = x-3

b = x+14

In supplementary angles , the formula are as follows,

a + b = 180

By putting the value, we get

x - 3 + x + 14 = 180

2x + 11 = 180

2x = 180 - 11

2x = 169

x = 169 ÷ 2

x = 84.5

So, a = 84.5 - 3

= 81.5

b = 84.5 + 14

= 98.5

Raja drove from A to B at an average speed of 50mph

The distance between A to B is 10 Miles

Raja took 30 minutes to drive from A to C

He drove from A to C at an average speed of 62mph

Work out Raja’s average speed as he drove from B to C

Answers

Answer:

44.7

Step-by-step explanation:

Speed = distance / time

speed from distance a to b = 50 = 10 / time

time = 10/50 = 12 minutes

Speed from a to c = 62 = distance / 30 minutes

distance = 62 x 0.5 = 31 m

diatance from b to c = 31 - 10 = 21

time = 30 - 12 = 28 minutes

speed = 21 / 28 minutes
