Answer:

14.2 feet

Step-by-step explanation:

Use the Pythagorean Theorem to solve both parts.

Part 1.

35 is the hypotenuse and 21 is a leg.

[tex]a^{2} +b^{2} =c^{2} \\a^{2} +21^{2} =35^2\\a^2 + 441 = 1225\\a^2 +441-441=1225-441\\a^2 =784\\\sqrt{a^2} =\sqrt{784} \\a = 28 feet[/tex]

28 feet represents how far the base of the ladder is from the house.

Part 2.

Now move the ladder 4 feet farther from the house. 28 + 4 = 32 ft.

Now you have a leg that is 32 feet and the hypotenuse is still 35 feet. Solve for the other leg.

[tex]a^{2} +b^{2} =c^{2} \\a^{2} +32^{2} =35^2\\a^2 + 1024 = 1225\\a^2 +1024-1024=1225-1024\\a^2 =201\\\sqrt{a^2} =\sqrt{201} \\a = 14.177 feet[/tex]

Round to the nearest tenth and you have 14.2 feet

Answer: ? = 1/2

Step-by-step explanation:

Your question is a bad example, so let me come up with one.

2/8 = 1/4

This is done by dividing both the numerator and denominator by the same value: 2/8 / 2/2

or

2/2 = 1, 8/2 = 4

We now have 1/4

or 9/36

What can we divide 36 by, 9 by? We need to divide by both for it to work.

9/3 = 3

36/3 = 12

3/12 But we can divide this again

3/3 = 1

12/3 = 4

1/4, we could also have divided 9/36 by 6/6 to get 1/4

For 1/8 to get ?/4, we do

8/? = 4

? = 1/2

, so the answer is 1/2/4 = 1/2*4 = 1/8

Step-by-step explanation:

The quantity of teaspoons of syrup it would take to make just one strawberry milkshake is 1 29/35 teaspoons

This is the number which gives the comparison between two quantities. The ratio of teaspoons of strawberry to make strawberry milkshake is the comparison between the two quantities.

Equate the ratio of teaspoons of strawberry syrup to strawberry milkshakes

Teaspoons of strawberry : make strawberry milkshake

3 1/5 : 1 3/4 = x : 1

16/5 ÷ 7/4 = x/1

cross product

16/5 × 1 = 7/4 × x

16/5 = 7/4x

x = 16/5 ÷ 7/4

x = 16/5 × 4/7

= (16 × 4) / (5 × 7)

= 64 / 35

= 1 29/35 teaspoons

Answer:

simply divide 12.50 by 5. Therefore each bracelet costs $2.05 : 2$ and 5 cents.

Step-by-step explanation:

The cost of each bracelet will be $2.5.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The cost of 5 bracelets = $12.50

Now,

Since, The cost of 5 bracelets = $12.50

So, The cost of 1 bracelets = $12.50 ÷ 5

                                         = $2.5

Thus, The cost of each bracelet will be $2.5.

Assuming simple interest, the formula to calculate the interest Ms. Paul paid is:

In the problem, here are the given information:

Principal (Money borrowed) = $1,200

Rate = 18% or 0.18 in decimal form

Time = 9 months or 0.75 year.

(Take note that the time in the formula is measured in years.)

Let's plug in the given information to the interest formula above.

Then, solve.

Therefore, Ms. Paul paid interest of $162.

Minimum number of gallons pumped after 30 days = 24,192,000 gallons

The minimum amount of water pumped in 1 minute = 1120 gallons

The minimum number of hours used for pumping per day = 12 hours

Number of minutes in 1 hour = 60 minutes

Number of minutes in 12 hours = 12 x 60 = 720 minutes

The minimum amount of water pumped per day = 1120 x 720

The minimum amount of water pumped per day = 806400 gallons

Let the number of days used for pumping be x

Let the total number of gallons pumped x days after pumping begins = y

Since 806400 gallons is pumped per day:

y = 806400x

Minimum number of gallons pumped after 30 days, that is, x = 30

y = 806400 (30)

y = 24,192,000 gallons

Minimum number of gallons pumped after 30 days = 24,192,000 gallons

Based on the given task content; the amount of money the customer needs to pay if given a discount of $5 off the second item bought is $38.50

Item 1:

Headphones = $25

Item 2:

CD = $18.50

Amount paid on the second item = original cost - discount

= $18.50 - $5

= $13.50

Total amount the customer needs to pay = cost of item 1 + Amount paid on the second item

= $25 + $13.50

= $38.50

In conclusion, the total amount the customer needs to pay for headphones and CD is $38.50

Answer:

First option is correct.

Step-by-step explanation:

Normally, Pete's dad deposits $25 into his bank account every week.

Now, he wants to deposit x extra dollars for 8 weeks. So, the total deposits for these 8 weeks will be:

8*(25 + x)

He wants to keep the total deposits above 500. So

8*(25 + x) > 500

Now we solve the inequality similarly to how we would solve an equality.

8*(25 + x) > 500

200 + 8x > 500

8x > 500 - 200

8x > 300

x > 300/8

x > $37.50

So the first option is correct.

Equation: (1/6)(-1)+(1/6)(2)+(1/6)(-3)+(1/6)(4)+(1/6)(-5)+1/6(6) = 0.5

First, let's see the points on the coordinate plane:

Now, let's remember that a function has every element of it's domain related with only one element from it's image.

Therefore, x = 2 would create a set of ordered pairs that is not a function. Let's see it in the plane:

As we can see, x = 2 has two values on the image: f(2) = 6 and f(2) = 7, and this never can happen in a function.

The vertex has these following coordinates.

Considering the coefficient a, we have that the vertex can represent either a maximum or a minimum point, as follows::

For this problem, the function is:

h(t) = -16t² + 160t + 200.

Then the coefficients are:

a = -16, b = 160, c = 200.
