please help me answer this math question​

Answer:

620

Step-by-step explanation:

Answer:

Kayla ran longer miles yesterday than today

Step-by-step explanation:

Distance  Kayla ran  yesterday be x

Then x =   [tex]\frac{9}{10}[/tex] mile

That is  x =  0.9 miles

The Distance she ran today be y

Then y  =  [tex]\frac{8}{9}[/tex]  of the distance she ran yesterday

So the distance Kayla  ran today

=   [tex]\frac{8}{9}[/tex]  [tex]\times \text { the distance she ran yesterday }[/tex]

On substituting the value

y = [tex]\frac{8}{9} \times\frac{9}{10}[/tex]

y = [tex]\frac{8}{10}[/tex]

y = 0.8 miles

x is greater than y

0.9 > 0.8

The initial amount of fish released would be the number shown in the equation.

The answer is 7

Final answer:

The initial number of fish released into the lake is 7, which is calculated by substituting t = 0 into the provided exponential growth function, P(t) = 7bt.

Explanation:

The growth of the fish population in the lake is modeled by the exponential function P(t) = 7bt, where t is the time in weeks after the release, and b is a positive unknown base. To find out how many fish were released initially, we need to consider the population at time t = 0. When we substitute t = 0 into the exponential function, we get P(0) = 7b0, and since any number raised to the power of 0 is 1, P(0) = 7. Therefore, the initial number of fish released was 7.

She will need 7 rolls of lace

Step-by-step explanation:

The given is:

We need to find how many rolls she will need

∵ The diameter of the table is 72 inches

- Change the inches to feet because the length of the lace in

   the rolls by feet

∵ 1 foot = 12 inches

∴ 72 inches = 72 ÷ 12 = 6 feet

∵ She plans to sew lace around the table

∴ The length of the lace is equal to the circumference of the table

∵ The circumference of a circle = π d, where d is its diameter

∴ The length of the lace = π(6)

∴ The length of the lace = 18.84955592 feet

∵ The lace comes in 3-foot rolls

- Divide the length of lace by 3 to find the numbers of the rolls

∴ The number of rolls = 18.84955592 ÷ 3

∴ The number of rolls = 6.283185

∴ She must buy 7 rolls

She will need 7 rolls of lace

The answer is D

Step-by-step explanation:

Answer:

D. $9x + $32 < $122

Step-by-step explanation:

given :

x is the number of visits

$9 is the cost per visit

$32 is the monthly dues

the amount she pays each month

= monthly dues + (cost per visit x number of visits)

= 32+ 9x  (rearrange)

= 9x + 32

given that she does not wish to spend more than $122, that means she wants to spend LESS than $122, i.e

amount spent < $122

or

9x + 32 < 122   (answer D)

Laura received 144 orders over the first year

Solution:

Given function is:

f(n) = 2n - 1

Where, "n" is the month

In the first month she put up her website she had only a single T-shirt order

f(1) = 2(1) - 1 = 2 - 1

f(1) = 1

There are 12 months in a year

For the second month, and third month and so on, substitute n = 2, 3 and so on

f(2) = 2(2) - 1 = 4 - 1 = 3

f(3) = 2(3) - 1 = 6 - 1 = 5

f(4) = 2(4) - 1 = 8 - 1 = 7

f(5) = 2(5) - 1 = 10 - 1 = 9

f(6) = 2(6) - 1 = 12 - 1 = 11

f(7) = 2(7) - 1 = 14 - 1 = 13

f(8) = 2(8) - 1 = 16 - 1 = 15

f(9) = 2(9) - 1 = 18 - 1 = 17

f(10) = 2(10) - 1 = 20 - 1 = 19

f(11) = 2(11) - 1 = 22 - 1 = 21

f(12) = 2(12) - 1 = 24 - 1 = 23

Thus total orders received over first year:

Total orders = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23

Total orders = 144

Thus she received 144 orders over the first year

Answer:

They need $2655 to raise to cover the costs of the printing and meet their goal.

Step-by-step explanation:

Consider the provided information.

As a fundraiser it cost them $155 to print the tickets and they would like to make at least a $2500 profit

Let x (in dollar) represents the fund raised.

The money spent on printing ticket is $155.

The profit they would like to make at least is $2500.

Therefore, the required inequality is:

[tex]x-155\geq 2500[/tex]

Simplify the inequality.

[tex]x\geq 2500+155\\x\geq 2655[/tex]

Therefore, they need $2655 to raise to cover the costs of the printing and meet their goal.

The tall of the tree is 23.048 ft.

Solution:

Given data:

Angular size of a tree =  [tex]\left(\frac{1}{2}\right)^{\circ}[/tex]

Distance = 0.5 miles = 2640 feet

To find the tall of the tree:

Formula to calculate the height of the tree is

[tex]$\text{Physical size}= \text{Angular size}\times\frac{2\pi\times \text{distance}}{360^{\circ}}[/tex]

                    [tex]$ = \left(\frac{1}{2}\right)^{\circ}\times\frac{2\pi\times 2640}{360^{\circ}}[/tex]

                    [tex]$ = \left(\frac{1}{2}\right)^{\circ}\times\frac{44\pi}{3^{\circ}}[/tex]

                    [tex]$ = 23.048[/tex]

Physical size = 23.048 ft

Hence the tall of the tree is 23.048 ft.

The solution of the equation is [tex]x=3[/tex] and [tex]y=1[/tex]

Explanation:

The equations are [tex]y=x-2[/tex] and [tex]y=-2 x+7[/tex]

First we shall solve the equation graphically.

The image of the graph is attached below.

This contains the solution to the system of equations.

The equations [tex]y=x-2[/tex] and [tex]y=-2 x+7[/tex] are plotted on the graph.

The intersection of these two equations are the solutions of the system of equations.

Thus, the intersection of the two equations are [tex]x=3[/tex] and [tex]y=1[/tex]

Now, we shall solve the equation algebraically.

Let us solve the equation using substitution method.

Let us substitute [tex]y=x-2[/tex] in [tex]y=-2 x+7[/tex], we get,

[tex]x-2=-2x+7[/tex]

Adding both sides by 2x, we have,

[tex]3x-2=7[/tex]

Adding both sides by 2, we get,

[tex]3x=9[/tex]

Dividing both sides by 3,

[tex]x=3[/tex]

Thus, the value of x is 3.

Substituting [tex]x=3[/tex] in [tex]y=x-2[/tex], we get,

[tex]y=3-2\\y=1[/tex]

Thus, the value of y is 1.

Hence, The solution of the equation is [tex]x=3[/tex] and [tex]y=1[/tex]

Answer:

The option [tex](\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2[/tex] is correct

Step-by-step explanation:

Given equation is [tex]\frac{1}{3}(33-y)=135.2[/tex]

The option shows correct usage of distributive property is

[tex](\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2[/tex]

( by distributive property [tex]a(x+y)=ax+ay [/tex] here [tex]a=\frac{1}{3}[/tex], x=33 and y=-y )

Therefore the option [tex](\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2[/tex] is correct.

The correct use of the Distributive Property for the equation 1/3(33 - y) = 135.2 is to apply multiplication to each term inside the parentheses by 1/3, resulting in (1/3 * 33) - (1/3)y = 135.2.

The question is asking for the correct use of the Distributive Property when solving the equation 1/3(33 - y) = 135.2.

The correct application of the Distributive Property to solve the equation would involve multiplying both terms inside the parentheses by 1/3. Here's how the property is correctly applied:

(1/3 * 33) - (1/3 * y) = 135.2

(33/3) - (1/3)y = 135.2

11 - (1/3)y = 135.2

Hence, the correct option that uses the Distributive Property properly is:

(1/3 * 33) - (1/3)y = 135.2

It’s been nice gnawing you

Step-by-step explanation:

While beavers don't 'speak' to trees in human terms, they interact with them by using their teeth to fell trees for food and building materials.

The question, 'what did the beaver say to the tree?', is somewhat humorous due to its anthropomorphic implication of a beaver communicating with a tree in human language. But, from a biological perspective, we could interpret this as asking about the interactions between beavers and trees. Beavers, as known dentition specialists, utilize trees for building dams and lodges and as a source of food. So, if a beaver could 'speak', it might 'tell' the tree that it's hungry, or that it needs materials for its dam. Of course, this is all figuratively speaking.
