The sum of 4 consecutive integers is 130

gogolik [260]

x + x + 1 + x + 2 + x + 3 = 130

Combine like terms.

4x + 6 = 130

Subtract 6 from both sides.

4x = 124

Divide both sides by 4.

x = 31

Which number should come next in the series?<br> 1 - 1 - 2 - 3 - 5 - 8 - 13

Darya [45]

This is part of the Fibonacci sequence. The next number is 21. Look at how much each number increases and the number before it.

1+1=2 (the number after 1 and 1)
1+2=3 (the number after 1 and 2)
2+3=5 (the number after 2 and 3)

So to solve we add 13+8=21

Please Help! Algebra 2!

Answer:

The interest rate of the account is $3\%$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=14\ years\\ P=\$1,863\\ A=\$2,830.97\\n=4$

substitute in the formula above and solve for r

$\$2,830.97=\$1,863(1+\frac{r}{4})^{4*14}$

$(2,830.97/1,863)=(1+\frac{r}{4})^{56}$

$(2,830.97/1,863)^{1/56}=(1+\frac{r}{4})$

$[(2,830.97/1,863)^{1/56}-1]=\frac{r}{4}$

$r=4*[(2,830.97/1,863)^{1/56}-1]\\ \\r= 0.03$

Convert to percent

$r= 0.03*100=3\%$

A square 20 cm long and a rectangle 24 cm long have the same perimeter. Find the area of the rectangle.

Nitella [24]

20 * 4 = 80 = perimeter of the square 24*2 = 48, the length of two sides of the rectangle. Deducting from 80 we are left with 32 and dividing by 2 we know the rectangle is 24 x 16 Area = L * W, so you can calculate the area of the rectangle.
