Answer:

t = 9/10. Try to substitute the t value into all the t's to see if the answer is correct. Ex: 2t+2, 2(9/10) + 2

Step-by-step explanation:

First you are going to multiply the 2 with the t+1, which is 2t+2. Then you are going to do the same with the other side of the equation. 102 times t+1 is 102t+102.

Now the equation is 2t+2 = 102t+102 = 10

You are now going to combine like terms, 2t - 102t = 102 - 2  = 10

-100t = 100 = 10.

Now subtract 100 from 100 and 10, which makes it: -100t = -90

Then you are going to make the -100t = -90 to -10t = -9, finally it is t = 9/10

Answer:

An integer, a, cannot be divided by an integer, b, when [tex]b=0[/tex]

Step-by-step explanation:

There is only one limitation when dividing two numbers. This is that you cannot divide a number by 0 as it is impossible to divide something into 0 groups.

As the integer, b, is the number that symbolized the number of groups something is divided into, this value cannot be 0.

2000 -637=1,363-1300=63

Step-by-step explanation:

Answer:

20%

Step-by-step explanation:

Let x represent the initial value of the stock at the beginning of 2006. And y the value at the end of 2006.

When it went up by 25% in 2006;

y = x + 25% of x = x + 0.25x = 1.25x

For the value to go back to the original price, it has to decrease from y to x;

y = 1.25x

The percentage decrease from y to x is;

= (y-x)/y × 100%

Substituting the values;

= (1.25x -x)/1.25x × 100%

= 0.25x/1.25x × 100%

= 0.2 × 100%

= 20%

Therefore, it will have to go down 20%

Step-by-step explanation:

The equation would be 99=1200(r)(0.75). You would solve the equation to get the answer 11/100. Then you could convert it to a decimal to get 0.11, Then multiply the decimal by 100 to get 11.

Answer:

5.9× 10^4

Step-by-step explanation:

I'm assuming that by "104" you actually meant "10^4," which reads "fourth power of 10."  Please be sure to use the symbol " ^ " to express exponentiation.

The sum of 2.5 × 10^4 and 3.4 × 10^4 is (2.5 + 3.4)×10^4

or

5.9× 10^4

Answer:

You need to add 12 pint of yellow.

Step-by-step explanation:

This is the method I used:

There is 4 pint of Yellow (Y) and 4 pint of Blue (B)

because they said is in equal amounts, so they are 50% each.

We need 80% Y and 20% B

so 4:20 = x=80   (4 pints is 20% as "how many pints" is 80%)

So x = 16

We already have 4 pint of Yellow, so we need more 12.

6.4 pint of yellow paint we need to add to the mixture.

"A percentage is a number or ratio that can be expressed as a fraction of 100."

"It is a statement which consists of equal symbol between two mathematical expressions."

For given example,

8 pint mixture of paint that is made up of equal amounts of yellow paint and blue paint.

Let we need 'x' amount of yellow paint.

To create a certain shade of green, you need a paint mixture that is 80% yellow.

So, we get an equation [tex]\frac{x}{8}\times 100 =80[/tex]

We solve above equation.

[tex]\Rightarrow \frac{x}{8}\times 100 =80\\\\\Rightarrow \frac{x}{8} = \frac{80}{100}\\\\ \Rightarrow x = 0.8\times 8\\\\\Rightarrow x = 6.4~~pints[/tex]

Therefore, 6.4 pint of yellow paint we need to add to the mixture.

Step-by-step explanation:

Here is the complete question:

Last month, a cafe had 3200 customers. 600 of them ordered gluten-free meals. What percentage of the customers ordered gluten-free meals?

To find the percentage of the customers who ordered gluten-free meals, we will divide the number of people who ordered glutton free meal by the total number of customers and then multiply by 100. This will be:

= 600/3200 × 100

= 0.1875 × 100

= 18.75%

Answer: 0.0625

Step-by-step explanation:

From the question, Steven rolled a 1-6 number cube four times. This means the 1-6 number cube has numbers 1, 2, 3, 4, 5 and 6. There are 3 odd numbers which are 1, 3 and 5. If the 1-6 number cube is rolled once, the probability will be:

3/6 = 1/2

Since Steven rolled the 1-6 number cube four times, the probability of getting an odd number on all four rolls of the die will be:

= 1/2 × 1/2 × 1/2 × 1/2

= 1/16

= 0.0625

Answer:

Step-by-step explanation:

Given the length of a rectangle = 3x+10

Width of the rectangle = x+12

Perimeter of the rectangle = 76ft

For us to get the area of the rectangle we need to get the value of its length and width.

Given the perimeter of a rectangle P = 2(L+W) where;

L is the length and W is the width, on substitution

76 = 2(3x+10+x+12)

76 = 2(4x+22)

76 = 8x+44

8x = 76-44

8x = 32

x = 32/8

x = 4

Substituting x = 4 into the function of the length and width we have;

Length = 3(4)+10

Length = 22feet

Width = 4+12

width = 16feet

Area of the rectangle = Length * Width

Area of the rectangle = 22feet * 16feet

Area of the rectangle = 352ft²
