Answer:

56°

Step-by-step explanation:

180 = 40 + (2x) + (3x)

180 - 40 = 40 + 5x - 40

140/5 = 5x/5

x = 28

2(28)

= 56

Answer:

m∠A = 56°

Step-by-step explanation:

A triangle contains 180°. So

180 - 40 = 140

2x + 3x = 140

5x = 140

x = 28

Now, plug in the value for x.

2(28) = 56

Check your work.

40 + 56 + 84 = 180

Answer:

a) 15.866%

b) 0.68268

Step-by-step explanation:

The scores for all the sixth graders at Roberts School on a statewide test are normally distributed with the mean of 76 and a standard deviation of 10.

We solve the above question using z score formula

= z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 76

σ is the population standard deviation = 10

a) What percent of the scores were below 66?

x < 66

Hence,

z = 66 - 76/10

z = -1

Probability value from Z-Table:

P(x<66) = 0.15866

Converting to Percentage =

0.15866 × 100

= 15.866%

b) What is the probability that a student earned a score between 66 and 86?

For x = 66

Hence,

z = 66 - 76/10

z = -1

Probability value from Z-Table:

P(x≤ 66) = 0.15866

x = 66 = 0.15866

For x = 86

Hence,

z = 86 - 76/10

z = 1

Probability value from Z-Table:

P(x≤ 86) = 0.15866

x = 66 = 0.15866

Probability value from Z-Table:

P(x = 86) = 0.84134

The probability that a student earned a score between 66 and 86 is calculated as:

P(x = 86) - P(x = 76)

= 0.84134 - 0.15866

= 0.68268

If you could explain/upload the centimeter grid it'd be explain.

But generally, what you should do is: calculate the number of centimeters on the longer side (length (l)) and note that, now calculate the number of centimeters on the shorter side (breadth(b)).

Use the formula, Area of a rectangle = l×b to solve your math problem

Answer: 197.82mm³

Step-by-step explanation:

Volume of a cylinder = πr²h

where,

π = 3.14

r = Diameter/2 = 6mm/2 = 3mm

h = 7mm

Volume = πr²h

= 3.14 × 3² × 7

= 3.14 × 9 × 7

= 197.82mm³

The volume of the cylinder is 197.82mm³

Answer:

A rectangle is a parallelogram because parallelograms have to have exactly 2 pairs of parallel sides. A rectangle has 2 parallel sides, therefore it is considered a parallelogram.

Answer: Rose used 2.075 pints of blue paint for her bedroom walls

Step-by-step explanation:

Amount of white and blue paint used for bedroom walls=8.3 pints

Amount of white paint used =3/4 x8.3 pints =6.225 pints

Amount of blue paint used = Amount of white and blue paint used for bedroom walls-Amount of white paint used

8.3 pints - 6.225 pints=2.075 pints

Answer: A. -6=n

-6=n

The weight for mom's boxes is obtained as 41.41 pounds.

What is weight?

Weight gauges how much gravity is pulling on a body.

The weight formula is provided by -

w = mg

Since weight is a force, it has the same SI unit as a force, which is the Newton (N).

Use a proportion to solve this problem.

Since the weight of the art projects is directly proportional to the number of art projects, we can set up the following proportion -

weight of 11 art projects / 11 = total weight / 24

Solving for the total weight -

total weight = (weight of 11 art projects / 11) x 24

total weight = 2.18 x 24

total weight = 52.32 pounds

So the total weight of the 11 art projects is 24 pounds, and if mom gets 7 of them, 4 art projects will be left weighing a total of -

weight of 4 art projects = (weight of 11 art projects - weight of 7 art projects)

weight of 4 art projects = (24 - (7/11) x 24)

weight of 4 art projects = 10.91 pounds

So, mom would be receiving 7 art projects weighing a total of -

weight of 7 art projects = (total weight - weight of 4 art projects)

weight of 7 art projects = (52.32 - 10.91)

weight of 7 art projects = 41.41 pounds

Therefore, mom's box would weigh 41.41 pounds.

Answer:

the mean of A and C is 10

Step-by-step explanation:

Given that

The mean of A and B is 20

The mean of B and C is 24

And, the mean of A, B and C is 18

We need to find out the mean of A and C

Since the mean of A and B is 20

So, a + b = 20 × 2

= 40

Likewise for B and C it is 48

And, for A, B and C, it is 54

So,

a + b = 40

b + c = 48

a + b + c = 54

So if we put the value of b + c in the above equation

a + 48 = 54

a = 6

b = 34

c = 14

Now the mean of the A and C is

= (6 + 14) ÷ 2

= 10

Hence, the mean of A and C is 10

Answer:

1261.1 revolutions

Step-by-step explanation:

Given

[tex]d = 16in[/tex] --- the diameter

[tex]Distance = 5280ft[/tex]

Required

The number of revolution completer

First, calculate the circumference (c) of the tire

[tex]c = \pi d[/tex]

[tex]c = 3.14 * 16[/tex]

[tex]c = 50.24[/tex]

Let the number of revolutions be n.

The product of n and the circumference equals to the total distance travelled.

So:

[tex]c * n = 5280 ft[/tex]

[tex]50.24in* n = 5280 ft[/tex]

Make n the subject

[tex]n = \frac{5280 ft}{50.24in}[/tex]

Convert feet to inch

[tex]n = \frac{5280 *12in}{50.24in}[/tex]

[tex]n = \frac{63360in}{50.24in}[/tex]

[tex]n = \frac{63360}{50.24}[/tex]

Solve for n

[tex]n = 1261.14649682[/tex]

Approximate

[tex]n = 1261.1[/tex]

Answer:

The area of the circle is 113.0 ft²

Step-by-step explanation:

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 6ft

π = 3.14

a = π * r²

we replace with the known values

a = π * (6ft)²

a = π * 36ft²

a = 113.04ft²

The area of the circle is 113.04ft²

round to the nearest tenth

a = 113.04ft²  = 113.0 ft²
