Explain how to find the product 3^5 x 3^2 using rules for exponents.

Answer:

Add 2 to each side

x=1/2

Step-by-step explanation:

(3√8x - 2 )= 4

Add 2 to each side

(3√8x - 2 +2= 4+2

3√8x = 6

Divide each side by 3

3/3√8x = 6/3

√8x = 2

Square each side

(√8x)^2 = 2^2

8x = 4

Divide each side by8

8x/8 = 4/8

x = 1/2

Answer:

this would not not be a valid conclusion because only that class was included In the poll not the entire school. Another method to determine the most popular subject is to include every class(the entire school)in the poll

Answer:

1) biased sample

2) random sampling

Step-by-step explanation:

Since the results are based on feedback of students in only one class, it's not a good representative of the entire student body.

Also, since it's a math class there will be a bias.

Better method would be randomly selecting students from the entire school students list and take their feedback

The inequality x / 3 ≤ 6 models the situation where a student shares a bag of fruit snacks equally with two friends and they each get at most 6 snacks. Solving the inequality, we find that there were at most 18 fruit snacks in the bag.

Explanation:

The inequality given for the scenario where the student shares fruit snacks with two friends is x / 3 ≤ 6. To solve this inequality, we multiply both sides of the inequality by 3 to isolate x on one side. This gives us x ≤ 18.

Therefore, the total number of fruit snacks that could have been in the bag is at most 18. This means if each person got exactly 6 fruit snacks, there would be 18 in the bag. But since the inequality allows for each person to have gotten at most 6 snacks, there could have been fewer than 18 snacks in the bag.

To find the value of x that results in a mean of 117 for the data set, sum the known values, multiply the mean by the total number of data points, and solve the resulting equation. In this case, the value of x is 149.

The question asks us to find the value of x so that the mean of the data set 102, 119, 107, 115, 110, and x is 117. To calculate the mean of a data set, you sum all the values and divide by the number of values.

First, we sum the known values: 102 + 119 + 107 + 115 + 110 = 553. Since the mean is given to be 117 and we have 6 values including x, the total sum of all the values should be 117 times 6, which is 702. Now we set up the equation to solve for x: 553 + x = 702.

To find x, subtract 553 from both sides of the equation:

553 + x - 553 = 702 - 553

x = 149

Therefore, the value of x that makes the mean of the data set 117 is 149.

Answer:

Sunflower=$900

4WD=$1090

Step-by-step explanation:

Wheareas 2WD costs $29,115 but when converted to 4WD it costs $30,205 then it means the cost of 4WD will be $30205-29115=$1090

The total cost of converting 2WD to 4WD with inclusion of sunroof is $31,105

Therefore, the total cost of 4WD and sunroof will be $31105-$29115=$1990

To get the amount for sunroof, we deduct the total cost that includes 4WD and sunroof from $1090

Cost will be $1990-$1090=$900

Answer:

The measure of arc MN is 88 degrees

Step-by-step explanation:

The complete question in the attached figure

we know that

The measure of the interior angle is the semi-sum of the arches that comprise it and its opposite

so

[tex]m\angle NQM=\frac{1}{2}(arc\ MN+arc\ LP)[/tex]

we have

[tex]m\angle NQM=103^o[/tex]

substitute

[tex]103^o=\frac{1}{2}(arc\ MN+arc\ LP)[/tex]

[tex]206^o=arc\ MN+arc\ LP[/tex] ----> equation A

Remember that

The measure of arc LP is 30 degrees more than the measure of arc MN

so

[tex]arc\ LP=arc\ MN+30^o[/tex] ----> equation B

substitute equation B in equation A

[tex]206^o=arc\ MN+arc\ MN+30^o[/tex]

[tex]2arc\ MN=206^o-30^o\\2arc\ MN=176^o\\arc\ MN=88^o[/tex]

The measure of MN is 88 degrees

From the diagram shown, the formula expressed below will be used to determine the measure of MN.

<NMQ = 1/2(arcLP + arcMN)

If the measure of LP is 30 degrees more than the measure of MN, then;

arcLP = 30 + arcMN

<NMQ = 1/2(30 + arcMN + arcMN)

2(103) = 30 + 2arcMN

206 - 30 = 2arcMN
arcMN = 88 degrees

Hence the measure of MN is 88 degrees

Answer:

The surface area of the composite solid = 480 square feet

Step-by-step explanation: Given that the rectangular prism is of length of 10 feet, width of 10 feet, and height of 6 feet.

A square pyramid with triangular sides with a height of 7 feet.

The base of the pyramid = width of the rectangular prism.

Pyramid base = 10 feet

A pyramid has 4 triangular faces

Area of a triangle = 1/2bh

Area = 1/2 × 10 ×7 = 35 square feet

Total surface area = 35 × 4 = 140

Rectangular prism has 6 faces

But we will be calculating for 5 faces

Total surface area = 2(10×6) + 2(10×6) + (10×10)

= 120 + 120 + 100

= 340

The surface area of the composite solid = pyramid surface + rectangular prism surface

= 140 + 340

= 480 square feet

Final answer:

The new rectangle formed by tripling the size of the original 13 feet by 4.3 feet rectangle has an area of 503.1 square feet, which is nine times larger than the original area.

Explanation:

To understand the scaling of the area of a rectangle when its dimensions are tripled, we need to recognize that the area of a rectangle is calculated by multiplying its length by its width.

The original rectangle has a length of 13 feet and a width of 4.3 feet, thus the area can be found by multiplying these two dimensions: 13 feet × 4.3 feet = 55.9 square feet.

When we triple both the length and width to create a new rectangle, the new dimensions will be 13 feet × 3 = 39 feet (length) and 4.3 feet × 3 = 12.9 feet (width). To find the new area, simply multiply these new dimensions: 39 feet × 12.9 feet = 503.1 square feet.

Therefore, the area of the new rectangle is 503.1 square feet, which is nine times larger than the original area because the area is proportional to the square of the scaling factor (3² = 9).

Answer:

It should cost $1.2 for 1 pound of apples.

Step-by-step explanation:

To find the unit rate, divide 3.60 by 3. This gives us 1.2, which shows that for every pound you would pay $1.2.

If 3 pounds of apples cost $3.60 then costs $1.20 for 1 pound of apples.

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b.

Given that,

Price for 3 pounds of apples = $3.60.

To find the cost of 1 pound of apple,

Use ratio property,

3 pounds cost = $3.60

1 pound cost = $3.60 / 3

1 pound cost = $1.20

The required cost of 1 pound of apples is $1.20.

Step-by-step explanation:

Answer: cup is $2.55

Saucer $0.55

Step-by-step explanation:

Cost of cup and saucer is $3.10

Let the cup be x

And saucer be y

I.e

X+y= 3.10......equation 1

Cup which is X is $2 more than the saucer

I.e x=2+y......equation 2

Substitute for X in equation 1

(2+y)+y=3.10

2+2y=3.10

2y=3.10-2

2y=1.10

Y=1.10/2

Y=$0.55

Substitute for y in equation 2

X=2+y

X=2+0.55

X=$2.55

Therefore

The cup is $2.55

The saucer is $0.55

Answer:

The arc is one-third of the circumference.

Step-by-step explanation:

The area of a circumference = 2πr

C = 2πr ... (1)

If an arc subtends a central angle measuring 2π/3 rad,

The length of the arc = rθ

Given θ = 2π/3

Length of the arc L = r(2π)/3

L = 2πr/3... (2)

L = 1/3(2πr)

Since C = 2πr

L = 1/3C

This shows that the arc is one-third of the circumference.

Given:

One interior angle is 50°.

Exterior angle is 95°.

To find:

The value of x and y.

Solution:

Exterior angle property of triangle:

The measure of an exterior angle is equal to the sum of the measures of the opposite interior angles.

⇒ 50° + y = 95°

Subtract 50° from both sides.

⇒ 50° + y - 50° = 95° - 50°

⇒ y = 45°

Sum of the adjacent angles in the straight line is 180°.

⇒ x + 95° = 180°

Subtract 95° from both sides.

⇒ x + 95° - 95° = 180° - 95°

⇒ x = 85°

The value of x is 85° and y is 45°.

Without additional context such as an equation, the problem to solve for x and y cannot be completed. In mathematics we need the relationship between the variables to solve for them.

The question seems to be incomplete as it does not provide the relationship between x and y or any equations for these values.

Normally in mathematics, we need an equation or a system of equations to solve for these variables. For instance, if we were given that x + y = 90 degrees (which is a complementary angle situation), we could subtract the known angle from 90 to find the other.

Without additional information, we are unable to solve this problem. Please make sure you provide all the necessary context when asking questions.
