Answer 1

Answer: x = 2.16

Step-by-step explanation:

Answer 2

The solution of the expression is, x = 2.16

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 3.5x/9 = 4.2/5

Now, We can simplify for x as;

⇒ 3.5x/9 = 4.2/5

⇒ 3.5x = 4.2 × 9 / 5

⇒ 3.5x = 7.56

⇒ x = 2.16

Thus, The solution is, x = 2.16

The number of apples required to bake a pie varies directly with the square of the diameter of the pie tin. If 4 apples are required for a pie tin with a diameter of 8 inches, how many apples are required for a pie tin with a diameter of 10 inches?

Answers

Answer:

5 apples

Step-by-step explanation:

Solution,

4 apples are required for a pie tin with a diameter of 8 inches

For 1 inch of the pie tin 8/4=2 apples are required.

For 10 inches 10/2=5 apples are required.

Answer:

6.25 apples

Step-by-step explanation:

Let the number of apples be a and diameter be d.

The relationship is:

a = kd², where k is he coefficient of proportionality

We have a = 4 when d = 8.

Find k:

4 = k*8²4 = 64kk = 4/64k = 1/16

The equation is now:

a = d²/16

Find a when d = 10:

a = 10²/16a = 100/16a = 6.25 apples

13. Raj and Eric went to lunch. Raj's total lunch bill was $9.53. This was 14%
higher than Eric's lunch bill. Which expression represents the amount of
Eric's lunch bill?
a.9.53-0.14
b.9.53/0.86
c.9.53•0.86
d.9.53/1.14

Answers

Answer:

C: $9.53*(0.86)

Step-by-step explanation:

To find Eric's lunch bill, we have to work backwards. Since Raj's bill is 14% higher, we have to make it 14% lower to get Eric's lunch bill. We can do this by multiplying the original price by 1-0.14.

$9.53*(1-0.14)=$9.53*(0.86)

Myra has a remote-controlled toy boat. She runs the toy boat on a lake at a constant speed. The graph of a function representing the toy boat’s distance, y, in feet, from the shore of the lake after x seconds includes the points (1, 8) and (1.5, 10.1).
Which statements are TRUE? Select all that apply.
A
The initial value of the function is 8.
B
The rate of change of the function is 4.2.
C
The equation for the function is y=3.8x+4.2 .
D
The toy boat’s speed on the lake is 4.2 feet per second.
E
The toy boat is originally 3.8 feet from the shore of the lake.

Answers

The coefficients of the linear equation are:

Rate of change = 4.2Initial value = 3.8

This means that the correct options are B and E.

How we can find the linear equation?

First, a general linear equation is written as:

y = a*x + b

Where a is the rate of change (also called slope) and b is the y-intercept (also called initial value).

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), then the rate of change is given by:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

In this case, we know that the line passes through:

(1, 8) and (1.5 , 10.1)

Then the rate of change is:

[tex]a = \frac{10.1 - 8}{1.5 - 1} = 4.2[/tex]

So the line is something of the form:

y = 4.2*x + b

To find the value of b we can use one of the given points, I will use (1, 8).

This means that when x =1, we have y = 8, replacing that we get:

8 = 4.2*1 + b

8 - 4.2 = b

3.8 = b

So we have:

Rate of change = 4.2Initial value = 3.8

Then the correct options are:

B and E.

Answer:

radius  = 11.00 yd (to the nearest hundredth)

Step-by-step explanation:

Volume of a cylinder = [tex]\pi r^2h[/tex],  where [tex]r[/tex] = radius and [tex]h[/tex] = height

Therefore, for this problem:  volume = 6458.98, [tex]\pi[/tex] = 3.14, [tex]h[/tex] = 17

Substituting these values into the above formula:

Volume = [tex]\pi r^2h[/tex],

6458.98 = 3.14 x [tex]r^2[/tex] x 17

6458.98 = 53.58 x [tex]r^2[/tex]

[tex]r^2[/tex] = 6458.98 ÷ 53.58 = 121

[tex]r[/tex] = √121

[tex]r[/tex] = 11

someone pls help me!!

Answers

Answer:  21

==============================================

Explanation:

x = the unknown number

x/3 = one third of the number

(x/3)+3 = added 3 to the previous result

(x/3)+3 = 10

x/3 = 10-3

x/3 = 7

x = 3*7

x = 21

------------

original number = 21

one third of it = 21/3 = 7

add on 3 to the previous result = 7+3 = 10

This confirms the answer.

Find the 21st term of the sequence 15,8,1,-6

Answers

Answer:

-125

Step-by-step explanation:

Each term is 7 less than the previous term.

1st term: 15

2nd term: 15 - 7

3rd term: 15 - 7 - 7 = 15 - 2(7)

4th term = 15 - 7 - 7 - 7 = 15 - 3(7)

Notice that each term is 15 minus a multiple of 7. The multiple is obtained by multiplying 7 by 1 less than the term number.

The formula is:

[tex] a_n = 15 - 7(n - 1) [/tex]

For the 21st term, multiply 7 by 20, and subtract from 15.

7 × 20 = 140

15 - 140 = -125

Using the formula:

[tex] a_{21} = 15 - 7(21 - 1) = 15 - 7(20) = 15 - 140 = -125 [/tex]

Answer: -125
