Answer:

3 stamps were left over

Step-by-step explanation:

Division

When a number m divides evenly by n the remainder is 0. For example, 120 divides exactly by 30 because 120/30=4 and the remainder is 0.

But 120 does not divide exactly by 50 because 120/50 = 2 and leaves a remainder of 20.

Jeff divided his 1,200 stamps equally among 7 stamp albums. If the division of 1,200 by 7 was exact, there won't be any stamp left over. Let's test it.

1,200/7 is 171.4, obviously is not exact, thus There were stamps left over.

How many?

Multiply the lower integer of division 171 by 7 to get: 171*7 =1,197. This means that 1,200-1,197= 3 stamps were left over

Answer:

21000

this is the answer

The value of the account is to reach $34,000 in 13 years with a rate of 3.7 compounded monthly is $ 21,000.

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

Brody is going to invest in an account paying an interest rate of 3.7% compounded monthly.

The rate of interest yearly will be

[tex]\rm Yearly \ rate = \dfrac{3.7}{12}\\\\Yearly \ rate = 0.308 \%[/tex]

The value of the account is to reach $34,000 in 13 years.

Amount (A) = $ 34,000

Time (t) = 13 years

Rate (r) = 0.308 %

Then the principal amount will be

[tex]\begin{aligned} A &= P (1 + \dfrac{r}{100})^{12*t}\\\\34000 &= P (1 + \dfrac{0.308}{100}) ^{13 * 12}\\\\34000 &= P (1.00308)^{156}\\\\P &= 21,044 \approx 21,000 \end{aligned}[/tex]

The principal amount is $21,000.

Answer: 4

Step-by-step explanation:

first you remove the parentheses it should look like this (4x+8-3x=12) then you collect the like terms (like terms have the same variable to the same power) it should look like this(x+8=12). then you move the constant to the right then last you calculate it should look like this x=12-8). then you subtract 12 by 8 and 4 is what you get.

Answer:

x= 5; Segment QR is the mid segment and YW is the base of the triangle. Mid segments are half the length of the base.

Step-by-step explanation:

2x - 3 = (x + 9) ÷ 2 Multiply both sides by 2

(2x - 3) • 2 = x + 9

4x - 6 = x + 9 Add 6 to both sides

4x = x + 9 + 6

4x = x + 15 Subtract x from both sides

4x - x = 15

3x = 15 Divide 3 on both sides

x = 15/3

x = 5

Answer:

4

Step-by-step explanation:

bc 4 times 4 is 16 plus 2 is 18

The rule of the pattern follows that each successive number is 3 lesser than the preceeding Value.

The first term = 65

Second term = 65 - 3 = 62

Third term = 62 - 3 = 59

Fourth term = 59 - 3 = 56

Fifth term = 56 - 3 = 53

Sixth term = 53 - 3 = 50

Therefore, each successive number is reduced by 3.

Step-by-step explanation:

No

Carbon monoxide concentrations sample in air from a large city are not normally distributed. This is often so because of the time of the day and that of the night. There exists different concentrations during the day, with respect to during the night. The companies and factories work during the day, so does most vehicles. This means that there tend to be a higher concentration during the day, than there will be during the night.

b)

Assuming that Y' is approximately normal, we can say that

P(Y' > 14) = P(Z > [√100(14 - 12)/9]) and this is equal to

Answer:

A=x2 - 2x -35

Step-by-step explanation:

x+5 x-7

The solution is Option D.

The area of the rectangle is A = x² - 2x - 35

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the value of A is

The length of the rectangle L = x + 5

The width of the rectangle is W = x - 7

And ,

The area of rectangle = L x W

Substituting the values in the equation , we get

The area of rectangle = Length of rectangle x Width of rectangle

The area of rectangle = ( x + 5 ) ( x - 7 )

On simplifying the equation , we get

The area of rectangle A = x ( x - 7 ) + 5 ( x - 7 )

The area of rectangle A = x² - 7x + 5x - 35

The area of rectangle A = x² - 2x - 35

Therefore , the value of A is x² - 2x - 35

Hence , the area of rectangle is x² - 2x - 35

Answer: z = 5/4

Step-by-step explanation: First simplify the equation by subtracting 2z from both sides and adding 7 to both sides to get 4z = 5.

Step by step below

6z -7 = 2z -2

-2z        -2z

4z = 5

Now divide both sides by 4 to get z = 5/4

4z/4 = 5/4

z = 5/4
