Answer:

A = 5

B = 9

C = 32

Step-by-step explanation:

a. if the width of the scale factor 1 is 10, then the width of the scale factor 1/2 is 1/2 of 10. so 5.

b. same thing as a. the length for scale factor of 1 is 18 so the length for scale factor of 1/2 is 9.

c. width of scale factor 1 is 10, so width of scale factor 3.2, 10 times 3.2, is 32

The slope of the line representing number of tests on the y-axis and the time in weeks on the x axis is 0.75.

As per the given question;

The total number of week is 36 weeks.

The total test conducted is 27.

As, number of tests are represented on the y-axis and the time in weeks on the x axis.

The slope is constant for the text and weeks.

Thus, slope (m) is determined  as;

m = Δy/Δx

m = number of tests/time in weeks

Put the values.

m = 27/36

m = 0.75

Therefore, the slope of the line representing number of tests on the y-axis and the time in weeks on the x axis is 0.75.

Step-by-step explanation:

5/100*4000=200+4000=4200*12=50400

Answer:

$4,368

Step-by-step explanation:

At the beginning of the first year, the principal (amount deposited) is $4000 at 4% interest.

The rate of interest in decimal is r = 4%/100 = 0.04

Interest for 1 year = P x r = 4000 x 0.04 = $160

So at the end of the first year, Marty's 4000 deposit will have grown to $4,000 + $160 = $4, 160

He deposits this amount into a new account at 5% interest
Interest rate r = 5%/100 = 0.05
Interest = 4160 x 0.05 = $208.00

Total money at the end of the second year = 4160 + 208 = $4,368

B rents for $1.62 per sq. feet is much cheap and better as compared to A

Yard and feet are used to estimate the length. Both of the units are used in the royal and US customary system of measurements. The value of one yard is equal to three feet.

To compute Square yard to Square Feet, where Square yard is equal to 9 Square Feet, multiply the value in Square yard by 9. one can also use the Square yard to Square Feet calculator.

1 yard² = 9 feet²

A rents for $27 per yard squared

hence A rents $27 for 9 feet squared

hence A rents $3 per feet squared( $27/9) which is costlier than $1.62 per feet squared

Hence B is better as it is cost effective.

The height of a tree that can cast a shadow of 28. 16 ft is 35. 2 ft

From the information given, we have that;

To determine the proportion we represent the expression as;

If 3ft casts a shadow of 2. 4ft

Then x ft can cast a shadow of 28. 16ft

cross multiply

x = 28. 16 × 3/ 2. 4

Multiply the numerators

x = 84. 48/ 2.4

x = 35. 2 ft

Thus, the height of a tree that can cast a shadow of 28. 16 ft is 35. 2 ft

the net change in the rainfall was that it was above the normal by 4.79 inches.

We are given that,

the end of June, the rainfall was above the normal by 8.2 inches.

Above the normal = + 8.2 inches.

Also, after that, it was below the normal by 3.41 inches.

Below the normal = - 3.41 inches.

Now, we need to find the net change in the rainfall

net change in the rainfall = + 8.2 inches - 3.41 inches

net change in the rainfall = 4.79 inches.

Therefore, the net change in the rainfall was that it was above the normal by 4.79 inches.

There are total 77 students in the sixth grade.

Given, there are 28 students that have braces.

out of which there are 4 students with braces for every 7 students.

Therefore, 4 ₊ 7 = 11, which means every 11 member has 4 members with braces.

Therefore, based on the given conditions, formulate:

28 × (4 ₊ 7) ÷ 4

28 × 11 / 4

now cross out the common factors.

The perimeter of tr8angle DEF that is similar to triangle ABC is: 18 cm.

If two triangles are similar to each other, and the perimeter of one is A with a side length of a, and the perimeter of the other is B with a side length of b, then, the following below is the ratio of their perimeters.

Perimeter of A/perimeter of B = a/b

Given that triangles ABC and DEF are similar triangles, we have the following:

Perimeter of triangle ABC = x

One side length of triangle ABC = 4 cm

Perimeter of triangle DEF = 12 + 6 + 9 = 27 cm

One side length of triangle DEF = 6 cm

Therefore:

x/27 = 4/6

Cross multiply

6x = (27)(4)

6x = 108

6x/6 = 108/6

x = 18

Thus, the perimeter of tr8angle DEF that is similar to triangle ABC is: 18 cm.

The proportion of the bag of sweets are smarties is 1/6.

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

Now it is given that,

There are 3 types of sweets in the bag.

Let s be number of the smarties sweet that Dan picks

c be the number of cola bottles  that Dan picks

and m be the number of marshmallows sweet that Dan picks

Now since, He picks 3 times as many cola bottles as smarties

Thus,

c = 3s

And, He picks twice as many marshmallows as smarties.

m = 2s

Now the total sweets in the bag = c + s + m

Substituting the value of c and s in the total sweets we get,

3s + s + 2s = 6s

Now, To find out the proportion of the bag of sweets that are smarties, divide the number of smarties by the total of sweets

Thus, the proportion of the bag of sweets are smarties = s/6s = 1/6

this is the required proportion of smarties in the bag.

Thus, the proportion of the bag of sweets are smarties is 1/6.
