Answer:

Fraction of jokes of Brandon that are funny = [tex]\frac{3}{10}[/tex]

Step-by-step explanation:

We are given that, 30% of the Brandon's jokes are funny.

Now, to convert percent into fraction, we will multiply it by [tex]\frac{1}{100}[/tex]

Now,

[tex]30\%=30\times\frac{1}{100}=\frac{30}{100} = \frac{3}{10}[/tex]

∴ [tex]\frac{3}{10}[/tex] of the Brandon's jokes were funny.

Final answer:

Using the properties of isosceles triangles, the acute base angle of the isosceles trapezoid, which is part of an isosceles triangle with a 46° vertex angle, is found to be 67°.

Explanation:

To find the measure of an acute base angle of the isosceles trapezoid that is part of an isosceles triangle with a 46° vertex angle, we can apply the properties of isosceles triangles. By the Isosceles Triangle Theorem, we know that the angles opposite the equal sides are equal.

Since the given triangle is isosceles, the two base angles must also be equal. Additionally, we know that the sum of all angles in any triangle is 180°.

Let's call each of the base angles B. Then, the sum of all angles in the triangle is:

46° + B + B = 180°

Now we solve for B:

2B = 180° - 46° = 134°

B = 134° / 2 = 67°

Thus, each base angle of the isosceles triangle is 67°. Next, considering the isosceles trapezoid, we know the adjacent angles must be supplementary because they are on the same line. This means that one base angle of the isosceles trapezoid equals:

180° - 67° = 113°

However, since the student is looking for the measure of an acute base angle of the trapezoid and 113° is an obtuse angle, the acute base angle is the original 67° angle that we found. This is because the acute and obtuse angles in the trapezoid are adjacent angles around the same vertex, and the acute angle is the angle that's interior to the triangle.

Therefore, the measure of an acute base angle of the trapezoid is 67°.

Answer:

15C is 59F

Step-by-step explanation:

As an equation, F = (1 4/5)C + 32. 1 and 4/5 is the same as 9/5.

Substitute 15 for C.

F = (9/5)C + 32

F = (9/5)(15) + 32   Multiply 15 by the top number in 9/5

F = 135/5 + 32       Convert 32 to a fraction over 5

F = 135/5 + 160/5     Add the numerators under the same denominator

F = 295/5        Divide

F = 59              Degrees in Farenheit

Therefore 15°C is 59°F.

Answer:

13.

Step-by-step explanation:

2g + 7

= 2(3) + 7

= 6 + 7

= 13.

Answer: 13

Step-by-step explanation: In this problem, we have the xpression 2g + 7 and we want to evaluate the expression when g is equal to 3.

To evaluate an expression, we simply plug the value of the variable into the expression and solve. So here, since g is equal to 3, we have 2 (3) + 7. 2 × 3 is equal to 6 so we have 6 + 7 which is equal to 13.

So the value of our expression when g is equal to 3 is 13.

Remember, when we see a variable like g next to a number, it means multiplication so you want to multiply by the value of the variable.

Grace is 9 years old. We found this by setting up a system of equations with the information given and solving for Grace's age.

We are given two pieces of information about Ava and Grace's ages:

To find Grace’s age, we can set up a system of equations based on the information provided:

The first equation can be written as:

A + G = 35

From the second piece of information, we can write:

A = 3G - 1

Now, we can substitute the expression for A into the first equation:

3G - 1 + G = 35

Combine like terms:

4G - 1 = 35

Add 1 to both sides:

4G = 36

Divide by 4:

G = 9

So, Grace is 9 years old.

Approximately $ 31419 profit is earned from selling books in entire month

Solution:

Given that Jodie had sold 885 copies of her new book

At the end of the month, she had sold 1,364 copies of her book

We have to determine the profit earned in the entire month

From given information,

Start of month sale = 885 copies

End of month sale = 1364 copies

Total copies of books sold = Start of month sold + end of month sold

Total copies of books sold = 885 + 1364 = 2249

Also given that each book profit is $ 13.97

Profit of 1 book = $ 13.97

Therefore for 2249 books, profit earned is given as:

Profit of 2249 books = $ 13.97 x 2249 = 31418.53

Therefore approximately $ 31419 profit is earned from selling books in entire month

Answer:

is it 8 apples to her mother or 10 since I had this exact problem?

Step-by-step explanation:

Ashe started with 32 apples in the basket initially.

To find the half of something just multiply 1/2 with the given value.

According to the given question Linda picked a basket of apples.

Assuming she had x apples initially.

She gave half of the apples to the neighbour,Therefore she now has            (x - 1/2x) apples which is = 1/2x apples.

Then she gave 10 to her mother,So the remaining apples she has now is

= ( 1/2x - 10 ) apples

= (x - 20)/2.

Then she gave half of the apples to her best friend so the no. of apples she has now is (x - 20)/2×1/2 which is = (x - 20)/4 and she kept the remaining 3.

∴ (x - 20)/4 = 3

x - 20 = 12

x =32.

The amount of Simon's monthly payment, rounded to the nearest cent, is approximately $240.17.

To calculate the monthly payment for Simon's loan, we need to use the formula for an annuity, which is derived from the amortization formula for loans. The formula to find the monthly payment (M) is:

[tex]\[ M = \frac{P \times r \times (1 + r)^n}{(1 + r)^n - 1} \][/tex]

where:

- [tex]\( P \)[/tex] is the principal amount of the loan ($43,000)

- [tex]\( r \)[/tex] is the monthly interest rate (APR divided by 12)

- [tex]\( n \)[/tex] is the total number of payments (20 years times 12 months per year)

First, we need to convert the annual percentage rate (APR) to a monthly interest rate by dividing by 12:

[tex]\[ r = \frac{2.4\%}{12} = \frac{0.024}{12} = 0.002 \][/tex]

Next, we calculate the total number of payments:

[tex]\[ n = 20 \text{ years} \times 12 \text{ months/year} = 240 \text{ months} \][/tex]

Now we can plug these values into the formula:

[tex]\[ M = \frac{43000 \times 0.002 \times (1 + 0.002)^{240}}{(1 + 0.002)^{240} - 1} \][/tex]

[tex]\[ M = \frac{43000 \times 0.002 \times (1.002)^{240}}{(1.002)^{240} - 1} \][/tex]

Using a calculator, we find:

[tex]\[ (1.002)^{240} \approx 1.558 \][/tex]

Now we can calculate the monthly payment:

[tex]\[ M = \frac{43000 \times 0.002 \times 1.558}{1.558 - 1} \][/tex]

[tex]\[ M = \frac{43000 \times 0.002 \times 1.558}{0.558} \][/tex]

[tex]\[ M = \frac{134.034}{0.558} \][/tex]

[tex]\[ M \approx 240.17 \][/tex]

Therefore, the amount of Simon's monthly payment, rounded to the nearest cent, is approximately $240.17.

Step-by-step explanation:

1.

The equation to solve is:

[tex]Ax+4Ax=51+2Ax[/tex]

The variable is "x", so we take all the terms with x's and take the number to one side. Then we add up the like terms of x's and solve for x. Shown below:

[tex]Ax+4Ax=51+2Ax\\Ax+4Ax-2Ax=51\\x(A+4A-2A)=51\\x(3A)=51\\x=\frac{51}{3A}\\x=\frac{17}{A}[/tex]

x = 17/A

Correct answer is A

2.

The equation is:

[tex]10y=3x-11[/tex]

[tex]10y=3x-11\\10(0.5)=3(2)-11\\5\neq -5[/tex]

first point doesn't lie on the graph.

[tex]10y=3x-11\\10(1)=3(4)-11\\10 \neq 1[/tex]

second point doesn't lie on the graph.

[tex]10y=3x-11\\10(0.7)=3(6)-11\\7=7[/tex]

This point lies on the graph. So, this is the answer.

Correct answer is (6, 0.7)

Let Miguel buy D DVDs. Each costing 10.99, that would make the cost:

10.99D

Shipping cost entire order is 9.99, so this would be added to DVD cost. Total cost:

10.99D + 9.99

This total cost can be NO MORE THAN 100, so this expression would be equal to or less than 100, so we can write:

[tex]10.99D + 9.99 \leq 100[/tex]

If we take 9.99 to the right side and subtract, it becomes:

[tex]10.99D \leq 90.01[/tex]

First choice is correct.

Second choice, clearly, isn't correct.

Third choice, similarly, isn't correct as well.

Fourth choice, because of "+" sign on right side (of 9.99) is also incorrect.

Fifth choice is what we initially got, so this is correct.

First and Fifth Choice is right.

the ones I have highlighted, we will multiply them all together, except for a 2.

we didn't multiply one of the 2's because they both have a two, so we only keep one of them.

so it is 2 x 5 x 2 x 2

The expression √215x should be further simplified for (a) 35 as the value of x

How to determine the value of x

From the question, we have the following parameters that can be used in our computation:

√215x

Taking each value of x from the list of options, we have

√215x = √(215 * 35)

Expanding, we get

√215x = √(5 * 43 * 7 * 5)

This gives

√215x = 5√301

Next, we have

√215x = √(215 * 118)

Expanding, we get

√215x = √(5 * 43 * 2 * 59)

This gives

√215x = √(25370)

Next, we have

√215x = √(215 * 34)

Expanding, we get

√215x = √(5 * 43 * 2 * 17)

This gives

√215x = √7310

Next, we have

√215x = √(215 * 7)

Expanding, we get

√215x = √(5 * 43 * 7)

This gives

√215x = √1505

Hence, the value of x is 35
