96=4x

x=24

Answer:

Step-by-step explanation:

the triangle on the left has dimensions 1.25x greater than the one on the right, because the bottom side of the triangle measures 45 units, but it measures 60 on the right. knowing this you can find that the side length on the left of the right triangle is 27, so x + 3 must be 27. x=24

Answer:

8 because if you take a row away from the total, you have 8, and that's how many are hidden

Step-by-step explanation:

Answer: there are eight blocks hidden in the cup.

Step-by-step explanation:

seeing that we don’t know how many blox are in the cup The cup would be a variable in this situation.

x + 4 = 12 cubes

to find your answer you would’ve solve for X, a.k.a. the cup.

x + 4 = 12 cubes

first you would do the inverse operation of addition so instead of adding four you subtract four from four, so that it cancels out. Whatever you do to one side you have to do to the other side so you would have to subtract 4 from The previous 12 cubes.

X = 12 - 4

and your final answer would be 8 cubes

x = 8

there are eight blocks/cubes hidden in the cup

z = - 300

z= -300

Step-by-step explanation:

Flip the equation so it looks like: 0.07z = -21

Then, divide it by 0.07 on both sides, which gets you -300.

You could also divide it by 7 and then multiply that answer by 100 if you want an extra step

The temperature in degrees Fahrenheit, F, is related to the temperature in degrees Celsius, C, by the equation
F=9/5 C+32
1.In the Sahara desert, temperatures often reach 50 degrees Celsius. How many degrees Fahrenheit is this?

2.In parts of Alaska, the temperatures can reach -60 degrees Fahrenheit. How many degrees Celsius is this?

3.There is one temperature where the degrees Fahrenheit and degrees Celsius are the same, so that C=F. Use the expression from the equation, where F is expressed in terms of C, to solve for this temperature.

Answers

1 is 122
2 is -51.1111F
3 is F=9/5c+32

The temperatures are in 50° Celsius, -60° Celsius and -40° Celsius when the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit respectively.

What is the temperature?

Temperature is a measurement of an object or material's warmth or coldness and an expression of thermal energy.

Given, the conversion expression of degrees Fahrenheit to degree Celsius.

The expression is,

F = (9/5)C + 32

For the option 1,

C = 50° Celsius

Then F = 9 x 50/5 + 32

= 90 +32

= 122° Fahrenheit

For the option 2,

C = -60° Celsius

Then F = 9 x -60/5 + 32

= -108 + 32

= -76° Fahrenheit

For the option 3,

C = F

Then F = 9F / 5 +32

F - 9F/5 = 32

-4F / 5 = 32

F = -160/4

F = -40° Celsius.

Therefore, the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit when the temperatures are in 50° Celsius, -60° Celsius and -40° Celsius respectively.

Answers

1. P is the principal amount, $630.00.
r is the interest rate, 6.5% per year, or in decimal form, 6.5/100=0.065.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 630 × 0.065 × 4 to get that:
The interest is: $163.80

2. =8000 x 9 x 18
=12,960
Total amount = 12960 +8000=
$20,960
3. annual interest rate = 15.9 %
initial charge = $126
to get the annual interest paid = 15.9% of $126
= 0.159 * $126 = $20.03
monthly interest paid would be = annual interest / 12 months
= 20.03 / 12 = $1.67
hence in 2 months Rita will pay = initial charge + monthly interest * 2
= $126 + $ 1.67 *2 = $ 126 + $3.34
= $ 129 .34

4. To find the amount of money in the account after 8.5 years we will first turn 5.6% into a decimal. We'll do that by moving the decimal within the percentage two places to the left. That leaves us with 0.056.
Next, we'll multiply our factors to help us find out how much interest will be accrued within the 8.5 years.
500 x 0.056 x 8.5 = 238.
Margarito will earn $238 within an 8.5 year time frame.
Since her original deposit was $500 and assuming no other deposits/withdrawls occur within the time frame, we will add $238 of interest to the original deposit.
500 + 238 = 738.
This means, that Margarito will have $738 in her savings account after 8.5 years of just accruing interest.

5. $18,260 divided by (/) $220,000 = .083 or .08. The interest is 8%.
Because Kelli is earning $18,260 a year, you need to get the number down to a decimal (which would be the interest) So, you have to divide the smaller number by the larger number. I use
x 18260
____ _______
100 % 220000
multiply 100x18260 and then divide by 220000. You get 8.3, or 8.3%, but if you round up, you get 8%.

1. 163.80
2. 12,960
3. 3.34
4. 738
5. 8.3%
