The sum of eight times a number and negative four exceeds twelve.

Answer: 8

Step-by-step explanation:

32/2 (50%)  = 16

32/4 (25%)  = 8

Add these together and you'll get 24. Subtract that from the initial amount and you'll have 8.

The salesman's commission for selling a car at Sal's car shop is $901.50.

To calculate the salesman's commission for selling a car at Sal's car shop, we must first determine the sale price's profit margin over the dealership's purchase price. The profit is found by subtracting the purchase price ($16,235) from the selling price ($22,245).

Profit = Selling Price - Purchase Price
Profit = $22,245 - $16,235
Profit = $6,010

Next, we calculate the commission by taking 15% of the profit:

Commission = Profit * Commission Rate
Commission = $6,010 * 0.15
Commission = $901.50

Therefore, the salesman's commission for selling the car is $901.50.

Answer:

She makes $60 per hour

Step-by-step explanation:

There are 5 days in a week and 40 divided by 5 is 8 and 8x10=80 and 80 subtracted by 20 gives you 60.

Final answer:

After deducting childcare expenses, Sally's actual hourly wage is $7.50 per hour.

Explanation:

The original question is about calculating Sally's actual hourly wage after accounting for childcare expenses. Sally works 40 hours a week and earns $10 per hour. However, she incurs a cost of $20 per day for childcare. Assuming she works 5 days a week, her weekly childcare expenses are $20 x 5 = $100. Therefore, her weekly take-home pay after childcare is (40 hours x $10/hour) - $100 = $400 - $100 = $300. Now, to find Sally's actual hourly wage after childcare expenses, divide her take-home pay by the number of hours worked: $300 / 40 hours = $7.50 per hour.

Answer:

106

Step-by-step explanation:

Given:

Thirteen fewer than three times his thinking number is 305.

Question asked:

What number is Tomás thinking ?

Solution:

Let Toma's thinking number be [tex]x[/tex]

As 13 fewer than 3 times his thinking number is 305.

The equation will be:

[tex](3 times of x) - 13 = 305[/tex]

[tex]3x - 13 = 305[/tex]

Adding both side by 13

[tex]3x = 318\\[/tex]

Dividing both side by 3

[tex]x = 106[/tex]

Thus,  Tomàs was thinking of a number is 106

Final answer:

To find the radius of the volleyball given its surface area, use the formula for the surface area of a sphere (4πr²) and solve for r. The approximate radius of the volleyball would be 4.25 inches based on a surface area of 227 square inches.

Explanation:

The surface area of a sphere formula is 4πr², where r is the radius. Given that the volleyball's surface area is about 227 square inches, we can find the radius by rearranging the formula as follows:

Answer:

Answer is B. (4,0)

Step-by-step explanation:

2x - y = 8

x + y = 4

solve the equation

2x - y = 8

y = 4 - x

substitute the value of y into the equation

2x - (4 - x) = 8

solve the equation

x = 4

substitute the value of x into an equation

y = 4 - 4

solve the equation

y = 0

answer is (4,0)

Step-by-step explanation:

To complete the square, take half of the second coefficient, square it, then add the result to both sides.

(-8/2)² = (-4)² = 16

x² − 8x + 16 = 9 + 16

Solving:

(x − 4)² = 25

x − 4 = ±5

x = 4 ± 5

x = -1 or 9

Answer:

part 1: x^2 + -8 x=9

part 2: Add 16 to each side

part 3: (x-4)^2 =25

part 4: -1 and 9

[tex]\bf \cfrac{cot(A)}{tan(A)}\implies \cfrac{~~\frac{1}{tan(A)}~~}{tan(A)}\implies \cfrac{~~\frac{1}{tan(A)}~~}{\frac{tan(A)}{1}}\implies \cfrac{1}{tan(A)}\cdot \cfrac{1}{tan(A)} \\\\\\ \cfrac{1}{[tan(A)]^2}\implies \cfrac{1}{tan^2(A)}\implies \cfrac{1^2}{tan^2(A)}\implies \left( \cfrac{1}{tan(A)} \right)^2\implies cot^2(A)[/tex]

Final answer:

To simplify cotA/tanA, we recognize that cotA is the reciprocal of tanA. The expression simplifies to cosA^2/sinA^2, which can also be written as cotA^2.

Explanation:

To simplify the expression cotA/tanA, we can use the fundamental trigonometric identities that relate the cotangent and tangent functions. The cotangent function, cotA, is the reciprocal of the tangent function, tanA, which means cotA = 1/tanA. Therefore, when we simplify cotA/tanA, we are effectively dividing the reciprocal of the tangent function by the tangent function itself.

The simplification would thus be:

Step-by-step explanation:

The sale price of the top after the 50% off discount is $8.44.

To calculate the sale price of the top with a 50% discount, follow these steps:

Step 1: Find the discount amount. The discount amount is 50% of the original price. To calculate this, multiply the original price by 0.50 (50% as a decimal):

Discount amount = 16.88 * 0.50 = 8.44

Step 2: Subtract the discount amount from the original price to find the sale price:

Sale price = Original price - Discount amount

Sale price = 16.88 - 8.44 = 8.44

When the customer applies the 50% off discount, they will pay $8.44 for the top, which is half of the original price of $16.88. This means they are getting a 50% discount on the original price.

[tex]b_n=\dfrac{2}{3}\cdot (9)^{n-1}[/tex]

Step-by-step explanation:

Given the geometric sequence

[tex]a_1=\dfrac{2}{3}\\ \\a_n=3a_{n-1},[/tex]

then

[tex]a_1=\dfrac{2}{3}\\ \\a_2=3a_1=3\cdot \dfrac{2}{3}=2\\ \\a_3=3a_2=3\cdot 2=6\\ \\a_4=3a_3=3\cdot 6=18\\ \\a_5=3a_4=3\cdot 18=54\\ \\...[/tex]

Hence,

[tex]b_1=a_1=\dfrac{2}{3}\\ \\b_2=a_3=6=\dfrac{2}{3}\cdot 9\\ \\b_3=a_5=54=\dfrac{2}{3}\cdot 9^2\\ \\...[/tex]

Answer:

There are 38 vocab. words in both weeks

Step-by-step explanation:

There are a few steps to this problem:

First, we know that there are 15 vocab. words in week 1.

Then, in week 2 there are 8 more words than in week 1. So that means 15+8 which equals 23.

Finally, we know that there were 15 words in the first week, and 23 in the second week. So now how many words were there in both weeks? To answer that, you add the number of words in the first week, to the number of words to the second week.

23 + 15 = 38 words total in both weeks

It would take [tex]1\frac{9}{91}[/tex] hour to complete the entire trip.

Step-by-step explanation:

Given,

Distance covered = [tex]30\frac{1}{3}[/tex] = [tex]\frac{91}{3}[/tex] miles

Time taken =[tex]\frac{1}{3}[/tex] hour

We know that;

Distance = Speed * Time

[tex]\frac{91}{3} = Speed*\frac{1}{3}[/tex]

Multiplying both sides by 3

[tex]3*\frac{91}{3} = Speed*\frac{1}{3}*3[/tex]

91 = Speed

Bob was driving at 91 miles per hour.

Now,

Distance to cover = 100 miles

Time required = x

Distance = Speed * Time

[tex]100=91x\\91x=100[/tex]

Dividing both sides by 91

[tex]\frac{91x}{91}=\frac{100}{91}\\x=1\frac{9}{91}[/tex]

It would take [tex]1\frac{9}{91}[/tex] hour to complete the entire trip.

To solve the 31st one just imagine and add all the cubes.

Start from the left side and keep on counting in your mind.

You will end with 25 cubes

For the 32nd one you can just draw a chart to know it.

Since this man has no bro or sis he is a single child.

The man in the picture is himself.

He is pointing to his picture and saying that 'that guys dad is my dad' and since he's a single child therefore its him itself.

So the answer is that man itself.

For the last one again try to draw a chart and connect the dots with the information.

So Lakisha had a bull dog. Since she has a bull dog she can't have Paul as her brother because paul is the brother of that girl who has her pet as horse.

This means paul is the brother of either Angela or Jessica. But its given that the brother of Angela is Ken therefore Paul is the brother of Jessica.

So the relations are

Lakisha-Bull dog, Stephen

Angela-Ken,XXXXX

Jessica-horse,Paul
