Answer:

c 12/15

Step-by-step explanation:

Because you have to multiply 3 to the denominator and what ever you do to the denominator u have to do to the numerator so If u did 3 time 5 it would be 15 but if u do 5 time 2 it would be 10 not 12 because the unit rate fraction is 2/3 so u multiply 3 to each denominator and numerator since 2/3 is the unit rate fraction

Step-by-step explanation:

There ya go. The numbers of possible amounts of mangos he could buy without exceeding his budget.

The possible values of mangos if, The cost of peaches is $2, The cost of the mangos is $1.25, and the Total money is $20, are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

A formula known as an equation uses the equals sign to denote the equality of two expressions. In other terms, it is a mathematical statement stating that "this is equivalent to that."

Given:

The cost of peaches =$2,

The cost of the mangos = $1.25,

Total money = $20,

Write the equation, if Henry buys 10 peaches,

10 × 2 + 1.25x = 20

Here, x is the number of mangos,

1.25x =  20 - 20

x = 0

Write the equation when Henry buys 4 peaches,

4 × 2 + 1.25x = 20

8 + 1.25x = 20

x = 20 - 8 / 1.25

x = 9.6 or 9 mangos

Thus, Henry can buy a maximum of 9 mangos if he buys at least 4 peaches.

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c (m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (6, 0)

m = [tex]\frac{0-6}{6-0}[/tex] = [tex]\frac{-6}{6}[/tex] = - 1

Note the line crosses the y- axis at (0, 6 ) ⇒ c = 6

y = - x + 6 or y = 6 - x ⇒ B

Answer:

A= 24 ounces and B= 36 ounces.

Step-by-step explanation:

Given: Solution A contain 30% salt= 0.30 salt.

           Solution B contain 55% salt= 0.55 salt.

           New mixture should be of 60 ounces with 45% salt.

Let x be the amount of mixture for solution A. Let y be the amount of mixture of solution B.

Scientist need to to obtain 60 ounce of mixture from solution A and B.

∴ [tex]x+y= 60\ ounces[/tex]

y= [tex]60-x[/tex]         equation 1

Now, solving to get final solution.

∴ [tex]0.3x+0.55y=0.45\times 60\ ounces[/tex]

Substituting the value of y from equation 1

⇒ [tex]0.3x+ 0.55\times (60-x)= 27[/tex]

⇒ [tex]0.3x+33-0.55x= 27[/tex]

⇒ [tex]-0.25x= -6[/tex]

∴ x= 24 ounces

Next, finding y

y= 60-x

∴ y= [tex]60-24= 36\ ounces.[/tex]

y= 36 ounces.

Now, we can say scientist would require 24 ounces of solution A and 36 ounces of solution B to obtain mixture of 60 ounces with 45% salt.

Answer:

Nathan's estimate would be greater than the actual product.

Step-by-step explanation:

Let a, b, c, d be natural numbers such that a<c and b<d

Multiplying a positive number on both sides doesn't affect the inequality

⇒a×b < c×b and c×b < c×d

⇒a×b < c×d

Here 67<70 and 36<40

∴67×36<70×40

Hence, Nathan's estimate would be greater than the actual product.

Mr. Jackson invested $800 at 6% per year and $ 2400  at 4 % per year

Mr. Jackson invested a sum of money at 6% per year, and 3 times as much at 4% per year.

Let the sum invested be ‘a’ and ‘3a’ at 6% per year and 4 % per year respectively

Also, his annual return totaled $144

We can form following equation on the basis of question:-

[tex]\begin{array}{l}{\text { Then, } \frac{a \times 6 \times 1}{100}+\frac{3 a \times 4 \times 1}{100}=\$ 144} \\\\ {\frac{6 a}{100}+\frac{12 a}{100}=144} \\\\ {\frac{6 a+12 a}{100}=144} \\\\ {\frac{18 a}{100}=144} \\\\ {18 a=14400} \\\\ {a=14400 \div 18}\end{array}[/tex]

a = $800

The amount of money invested at 6% = a = 800

The amount of money invested at 4 % = 3a = 3(800) = 2400

So, the amount of money invested at 6% is $800 and the amount of money invested at 4% is $ 2400

To determine the amounts Mr. Jackson invested, the problem was solved by setting up a simple equation and solving for x, which represents the amount at 6% interest. Mr. Jackson invested $800 at 6% and $2400 at 4% to receive a total annual return of $144.

The question involves solving a system of linear equations to find how much Mr. Jackson invested at two different interest rates if his total annual return is $144. To solve the problem, let's define the amount invested at 6% per year as x and the amount invested at 4% as 3x, since the latter is three times as much.

The interest from the investment at 6% would be 0.06x, and the interest from the investment at 4% would be 0.04 × 3x. Since these add up to $144, we can write the equation:

0.06x + 0.04 × 3x = 144

Solving this equation:

Since x represents the amount at 6%, Mr. Jackson invested $800 at 6% and $2400 at 4% because the investment at 4% is three times as much.

The value remains under the radical is 8 ⇒ last answer

Step-by-step explanation:

Let us revise how to write the exponent as a radical

Example:

Now let us solve your problem

∵ [tex]1250^{\frac{3}{4}}=\sqrt[4]{1250^{3}}[/tex]

- Factorize 1250 to its prime factors

∵ 1250 = 2 × 5 × 5 × 5 × 5

∴ [tex]1250=2*5^{4}[/tex]

∴ [tex]\sqrt[4]{(2*5^{4})^{3}}=\sqrt[4]{2^{3}*5^{12}}[/tex]

∵ 2³ can not go out the radical because 3 < 4 and not divisible by it

- [tex]5^{12}[/tex] can go out the radical because 12 can divided by 4

∵ 12 ÷ 4 = 3

∴ [tex]5^{12}[/tex] can go out the radical as 5³

∴ [tex]\sqrt[4]{1250}=5^{3}\sqrt[4]{2^{3}}[/tex]

∴ [tex]\sqrt[4]{1250}=125\sqrt[4]{8}[/tex]

∴ The value remains under the radical = 8

The value remains under the radical is 8

Step-by-step explanation:

THe markup is the difference between the Selling Price and Cost.

As a percentage, we would get the markup in terms of cost.

First,

Selling Price = 4.50

Cost = 3.00

So,

Markup = SP - Cost = 4.50 - 3.00 = 1.50

As a percentage, we would divide the markup by cost and then multiply the answer by 100. That's:

1.50/3 = 0.5 * 100 = 50%

This is a mathematics problem involving the calculation of the slope of a line graph. The machine produces 20 soda bottles per minute as concluded from the given coordinates (4,80) and (7,140).

The subject of this question falls under Mathematics, specifically the topic of linear relationships or functions. The task is to calculate the rate at which soda bottles are made per minute using the given coordinates of the graph, (4,80) and (7,140).

First, we need to calculate the slope of the line represented by these points since the slope corresponds to the number of soda bottles produced per minute. In a linear relationship, the slope of the line can be found using the formula: slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

In this case, (x1, y1) is (4,80) and (x2, y2) is (7,140). Plugging these values into the slope formula, we get: slope = (140 - 80) / (7 - 4) = 60 / 3 = 20.

So, the machine produces 20 soda bottles per minute.

Answer:

The value in box of circle B is 3 and the value in box which belongs in both circle B and S is 6 and value which belongs in circle S is 1 and the value of box outside both the circle is 2.

Step-by-step explanation:

In given Venn diagram

ε = class of 12 pupils

pupils who have brother B = 9

pupils who have sister S = 7

pupils who have neither brother nor sister = 2

Hence the Venn diagram is drawn in the attachment for your reference.

n(E) =12

n(neither B nor S) = 2

So, n(B or S)= n(E) - n(neither B nor S)= 12-2=10

n(B) = 9

n(S) = 7

Now, addition theorem,

n(B or S) = n(B) + n(S) - n(B and S)

[tex]10=9+7-n(B\ and \ S)\\n(B\ and \ S) = 6[/tex]

So the value in box which is in both circle B and S is 6.

So the Box which contains only brothers = n(B) - n(B and S)  = 9 - 6 = 3

Value in box of circle B is 3.

So the Box which contains only Sisters = n(S) - n(B and S)  = 7 - 6 = 1

Value in box of circle S is 1.

There are 12 pupils in a class so, the number of pupils having both brother and sisters are 6 and the pupils had either brother or sister are 10.

Given :

Given that there are pupils in a class that is, n(E) = 12

Pupils who have brother, n(B) = 9

Pupils who have sister, n(S) = 7

Pupils who have neither brother nor sister, n(neither B nor S) = 2

So,  n(B or S) = n(E) - n(neither B nor S)

                      = 12 - 2 = 10

n(B or S) = 10

Now, through the addition theorem:

n(B or S) = n(B) + n(S) - n(B and S)

10 = 9 + 7 - n(B and S)

n(B and S) = 6

The system of linear inequalities for Kayla's fruit purchase is x + y ≥ 15 to represent the quantity of fruit, and 0.65x + 0.78y < 20 to represent the budget constraint.

Explanation:

The student's question is asking for a system of linear inequalities that would model the situation in which Kayla wants to buy at least 15 fruits consisting of apples and oranges, without spending more than $20. Given that apples (x) are $0.65 each and oranges (y) are $0.78 each, we can set up the following inequalities:

x + y ≥ 15

0.65x + 0.78y < 20

The first inequality represents the requirement that Kayla needs to buy at least 15 pieces of fruit. The second inequality represents the constraint that she needs to spend less than $20 on her purchase.

Answer:

B. $336.09

Step-by-step explanation:

Monthly payment = $876.09

Interest rate = 4.8%

Convert the annual interest rate to monthly rate = 4.8% / 12

Monthly rate = 0.4% or 0.004

Amount going towards interest payment = 0.004* loan amount

Interest = 0.004 * 135,000

Interest = $540
