Number 15 Part B
Help me Explain and Solve

Answer: 8 cupcakes.

Step-by-step explanation:

4 cupcakes every 5 hours implies that 4 cupcakes grow in the span of 5 hours. if this is a ten hour period as the question states, then you have 8 cupcakes, as 4 cupcake batches grew twice in that 10 hour span.

Answer:

  3 times

Step-by-step explanation:

We observe that both functions are vertically scaled versions of the parent quadratic y = x^2. The ratio of scale factors is 2.7/0.9 = 3. That is, ...

  g(x) = 3f(x)

This means that whatever vertical difference f(x) may show over the interval, g(x) will show 3 times that difference.

The average rate of change of g(x) is 3 times that of f(x).

Answer:

the answer is -352..........

Answer:

A=πr2

Step-by-step explanation:

Area of a circle is found by the following formula-

Area of Circle = πr^2

Where -

π = pie, value of 3.14 or 22/7

r = radius of a circle

Example -

A circle has a radius of 10 cm. Find the area of the circle.

Solution -

Area of Circle = A=πr^2

A = 3.14*10^2

A= 314 cm

Note - Most preferably, 3.14 is the most common value used for pie. You can also use 22/7, and would end up with roughly the same answer, but it takes more time to solve with a fraction like 22/7.

Answer:

z

Step-by-step explanation:

The Z score is the number of standard deviations a randomly selected value is from the population mean. Using a Z look-up table, the Z score can be converted into the probability of drawing the value from the population.

Answer:

[tex]x2=\frac{y2-y1}{m} +x1[/tex]

Step-by-step explanation:

Step 1: Multiply both sides by (x2-x1)

m(x2-x1)=y2-y1

Step 2: Divide both sides by m

x2-x1=(y2-y1)/m

Step 3: Add x1 to both sides

[tex]x2=\frac{y2-y1}{m} +x1[/tex]

Answer:

[tex] \frac{7}{72} [/tex]

Step-by-step explanation:

The question is :

[tex] \frac{1}{9} \div \frac{8}{7} [/tex]

We need to take the reciprocal which means invert the :

[tex] \frac{8}{7} [/tex]

So, it will be :

[tex] \frac{1}{9} \times \frac{7}{8} [/tex]

After that , do 1 × 7 on numerator and 9 × 8 on denominator....

After multiplication you'll get :

[tex] \frac{7}{72} [/tex]

1/9 divided by 8/7 is equal to 7/72.

To divide fractions, you can use the following rule: invert the second fraction and multiply it by the first fraction.

In this case, you have:

1/9 ÷ 8/7

To divide, we invert the second fraction:

1/9 × 7/8

Next, multiply the numerators (top numbers) together and the denominators (bottom numbers) together:

(1 × 7) / (9 × 8)

This simplifies to:

7/72

Therefore, 1/9 divided by 8/7 is equal to 7/72.

Answer:

No, it is not a solution

Step-by-step explanation:

First let's simplify 2x - 5 = 3

2x - 5 = 3                            (add 5 to both sides)

2x - 5 + 5 = 3 + 5

2x = 8                                 (divide both sides by 8)

2x ÷ 2 = 8 ÷ 2

x = 4

As you can see, 7 is not a solution for 2x - 5 = 3

We can double check by substituting 7 for x:

2(7) - 5 = 3

14 - 5 = 3

9 ≠ 3

Answer:

Integers such as 9 and 25, whose square roots are whole numbers, are called perfect squares.

hope it help mark as brainliest

Answer:

perfect squares

Step-by-step explanation:

Square roots are the reverse operation of squaring a value. Numbers whose square roots are Integers are  

called perfect squares. For example: √4 2. The square root sign (√ ) is called a radical. Use can use a  

calculator to determine the approximate value of a square root, estimate where the square root is on a

number line, or simplify square roots, as shown below

Answer:

4. B

5. D

Step-by-step explanation:

4. Draw a line at angle to the line segment JK.

Then make three arcs on the new line using a compass without changing the setting.

Join the last arc to the endpoint of the line segment (in this case, K) and draw two parallel lines originating from the other two arcs.

5. Recall, there are two lines a and b

where x is the geometric mean.

Draw a line.

Label a point on the line (say, R)

Construct a segment (or arc) with endpoint R and length "a".

Construct a segment (or arc) with length "b" adjacent to the previous segment.

Label the endpoints (say, S and T). The line segment from point RS is "a" and that from point ST is "b".

Construct the perpendicular bisected of segment RT.

Label the midpoint of segment RT.

Using the midpoint as the center and half the length of RT as the radius, construct a semicircle.

At S, construct the perpendicular to segment RT. Label the intersection between the semicircle and perpendicular (say, Y)

SY is the geometric mean.

a/x = x/b is RS/SY = SY/ST

-Chetan K

Answer:

1.40

Step-by-step explanation:

When we look at the diagram, we want to find what is opposite and adjacent as well as the hypotenuse to the given degree.

AB = hypotenuse

BC = opposite

AC = adjacent

Since we are looking to find BC and we are given 2 on AC. We have opposite and adjacent which means we are using TOA in SOH-CAH-TOA. So aftrr identifying these, we can set up our equation:

tan (35) = x / 2

Tan(35) is .7002 so we can replace that part of our equation.

.7002 / 1 = x / 2

The 1 is there as a place holder. We can then cross multiply.

1 × x = 1

.7002 × 2 = 1.4004

The answer we have now is 1.4004, but we have to round to the nearest hundredth. So then, our final answer is 1.40.

BC = 1.40

The area of a shape is the amount of space it occupies.

The largest garden you could make is 49 square meters

The perimeter is given as:

[tex]\mathbf{Perimeter = 28}[/tex]

This is calculated as:

[tex]\mathbf{2 \times (Length + Width) = 28}[/tex]

Divide by 2

[tex]\mathbf{Length + Width = 14}[/tex]

This means that, the sum of the dimensions must equal 14.

So, the possible dimensions are:

The garden with the largest dimension is: 7 by 7 meters.

So, the area of garden is:

[tex]\mathbf{Area = 7m \times 7m}[/tex]

[tex]\mathbf{Area = 49m^2}[/tex]

Answer:

3  3/11

Step-by-step explanation:

The best way to divide fractions is to not divide them at all.

Convert both mixed numbers into improper fractions.

4 times 2 is 8

8 + 1 is 9

I have 9/2 halves. Don't forget to put the negative back in.

1 times 8 is 8

8 + 3 is 11

I have 11/8 eighths. Dont forget to put the negative back in.

You will end up with

-9/2 ÷ -11/8

Flip the second fraction and change the division sign to a multiply sign

-9/2 × 8/-11

Multiply the numerators together and the denominators together

-9 x 8 and 2 x -11

-72 / -22

Dividing a negative by a negative will give us a positive
