The price of an item yesterday was 85 . Today, the price rose to 136. Find the percentage increase.

Answer: y = 1.2

Step-by-step explanation:

1.5(3y+2) - y = 2(8y-6)

4.5y + 3 - y = 16y - 12

3.5y + 3 = 16y - 12

-3. -3

3.5y = 16y - 15

-16y. -16y

-12.5y = -15

—— —— <—fraction symbol to divide

-12.5. = -12.5

y. =. 1.2

Answer:

5y=6

Step-by-step explanation:

4.5y+3-y=2(8y-6

16y-12

3.5y+3-16y=-12

12-3

-12.5y=-12-3=15

-125y=--150

Answer:

Volume = 9424.78 cubic centimeters

Capacity = 9.425 liters

Step-by-step explanation:

Volume of a cylinder given r = radius and h = height is
V = πr²h

Given r = 10 and h = 30

V = π (10)² . (30) ≈ 9424.78  cubic centimeters

1 liter = 1000 cubic centimeters this works  out to
9424.78/1000 = 9.42478 ≈ 9.425 liters

Answer:

The factor which is used to convert feet per minute into miles per minute is:

1 ft per minute=0.000189 miles per minute.

( since, 1 ft.= 0.000189 miles )

Step-by-step explanation:

Conversion factor--

A conversion factor is a factor which is used to convert one unit to another by multiplication or division by a specified number.

We know that:

1 miles= 5280 ft.

This means that:

1 ft.=1/5280 miles

i.e. 1 ft.= 0.000189 miles.

Hence, 1 ft per minute=0.000189 miles per minute.

Ching Weng spend 39.75 less then she budgeted on the personal items for the month of January.

We have Ching Weng's budget and expenses for personal items.

We have to determine how much more or less did she spend than she budgeted.

A budget is an estimation of revenue and expenses over a specified future period of time.

According to the question -

The total amount kept by Ching Weng as budget = $95 + $15 + $20 = $130

The total expenses of Ching Weng = $60.75 + $7.85 + $21.65 = $90.25

Since, expenses are less than budget, she spend less than she budgeted. Thee amount saved by her is =

Total budget - total expenses = 130 - 90.25 = $39.75

Hence, Option A is the correct alternative.

The cost of the membership after a discount of $ 136 will be $ 204.

We are given that:

a local gym is giving a discount for the promotional offer it has to make.

Discount percentage = 40 %

Cost of the annual membership = $ 340

Discount = 40 % of $ 340

Discount = 40 / 100 × $ 340

Discount = 0.4 × $ 340

Discount = $ 136

So, the cost of annual membership after discount will be:

Cost = $ 340 - $ 136

Cost = $ 204

Therefore, the cost of the membership after a discount of $ 136 will be $ 204.

Answer:

y = 3x + 9

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 )

y = 3x + 4 ← is in slope- intercept form

with slope m = 3

• Parallel lines have equal slopes , then

y = 3x + c ← is the partial equation of the parallel line

to find c substitute (1, 12 ) into the partial equation

12 = 3 + c ⇒ c = 12 - 3 = 9

y = 3x + 9 ← equation of parallel line

For less than 6 hours, Hank's Movers charge less.

Acme movers charge $210 plus $20 per hour, so if they work for x hours they charge:

A(x) = $210 + $20*x

Hank's movers only charge $55 per hour, so here the linear equation is:

H(x) = $55*x

They charge the same amount when:

A(x) = H(x)

$210 + $20*x = $55*x

Now we can solve that to get:

$210 + $20*x = $55*x

$210 = $55*x - $20*x = $35*x

$210/$35 = x = 6

So, for 6 hours, both companies charge the same amount.

For less than 6 hours, Hank's Movers charge less.

Answer:

Step-by-step explanation:

Account Y would earn Monica about $62.70 more interest than account X.

Given Monica deposits $3000.

Bank offers two different savings accounts.

Account X pays 2.1% simple annual interest and Account Y pays 2.4% compounded annually, both for 5 years.

For account X, we have:

Principal (P) = $3000

time (t) = 5 years

rate of interest (r) = 2.1%

we need to calculate simple interest:

Simple interest = P×t×r/100

= 3000c5×2.1/100

= $315

simple interest for 5 years is $315

For account Y, we have:

Principal (P) = $3000

time (t) = 5 years

rate of interest (r) = 2.4%

we need to calculate Compound interest:

compound interest = P×(1₊rate)^time ₋ P

= 3000(1₊2.4/100)⁵ ₋ 3000

= 3000(1.024)⁵ ₋ 3000

= 3000(1.12589907) ₋ 3000

= 3377.69 ₋ 3000

= $377.69

The compound interest for 5 years is $377.7

compound interest of account Y ₋ simple interest of account X

= 377.7 ₋ 315

= $62.70

hence the right option is that account Y would earn Monica about $62.70 more interest than account X.

8 liters of 30 percent vinegar solution was mixed.

Percent or percentage is defined as the value for every 100. the simple way to calculate percentage is by dividing the data with the whole data and multiplying it by 100.

4 liters of 15 percent vinegar solution contains:

(15/100)×4 liters of vinegar=0.6 liters

x liters of 30 percent vinegar solution contains:

(30/100)× x liters of vinegar=0.03x liters

Therefore the total vinegar in the 25 percent solution is (0.6+0.3x) liters.

Total volume of the solution is (x+4) liters

(x+4) liters of 25 percent solution contains:

(25/100)×(x+4) liters =(0.25x+1) liters

Now we can equate both values to calculate the value of x from a linear equation:

(0.6+0.3x)=(0.25x+1)

or, 0.05x=1-0.6

or, x= 8 liters

Hence 8 liters or 30 percent solution was mixed.

The perimeter of the right angled triangle is 24 units.

The perimeter is defined as the sum of all sides of a polygon. To calculate the perimeter of a triangle we add the length of all the 3 sides of the triangle.

The given side lengths are 6 and 8 units.

We know from Pythagorean theorem that for a right angled triangle the sum of the squares of the legs is equal to the square of the hypotenuse of the triangle.

Hypotenuse is the longest side in a right angled triangle.

Therefore the hypotenuse in this triangle is given by:

Hypotenuse² = 6² + 8²

or, hypotenuse = √(36 + 48) units

or, hypotenuse =√100

or, hypotenuse= 10 units

Now perimeter = (6 + 8 + 10) units = 24 units.

Hence the perimeter of the given right angled triangle is 24 units.
