The perimeter of a rectangle is 48 inches. The rectangle is twice as long as it is wide. What is the length of the rectangle?
Α: 8 inches
B: 16 inches
C: 32 inches
D: 24 inches
Answer: B
Step-by-step explanation:
l = 2
2 ( l + w ) = 48 , or , l + w = 24
w = 8 , & , so , l = 2 w = 16 inches.
How to factor binomials?
Answer:
Let us consider a binomial expression
For example,
x²+(a+b)x+ab
x²+ax+bx+ab
x(x+a)+b(x+a)
(x+a)(x+b)
Therefore, the above binomial expression has two factors (x+a) and (x+b).
Now by numericals
Consider, x²+12x+35
[tex] {x}^{2} + 12x + 35\\Factors\:of\: 35\: is\: 5\: and\:7 \\ {x}^{2} + 5x + 7x + 35 \\ x(x + 5) +7(x + 5) \\ (x + 5)(x + 7)[/tex]
Here, (x+5) and (x+7) are the factors of the binomial expression x²+12x+35.
Answer:
Binomials are two-term expressions connected with a plus sign or minus sign, such as {ax+b}ax+b. The first term will always include a variable, while the second term may or may not. 1st: factoring is when you break a large number down into it's simplest divisible parts. Each one of these parts is called a "factor." So, for example, the number 6 can be evenly divided by four different numbers. 2nd: A binomial is simply the addition or subtraction of two numbers, at least one of which contains a variable. Sometimes these variables have exponents, like x^5 or 5y^6. 3rd :When first factoring binomials, it can help to reorder equations with ascending variable terms. This means you find the highest possible number that both parts of the binomial are divisible by. If you're struggling, simply factor both numbers on their own, then see what the highest matching number is.

The radius of a circular sign is 12 inches. Equal parts of the sign are painted red and yellow. How many square inches are painted in each color? Use 3.14 for Pi
Answer:
226.08 square inches
Answer:
Step-by-step explanation:
First we find Area
12^2* 3.14= 452.16
Then we know that half of the sign is painted red and the other half is painted yellow
452.16 / 2 = 226.08
226.08 square inches is painted yellow and 226.08 square inches is painted red

The cost of a game g with 7% sales tax can be represented by the expression g + 0.07g. Simplify the expression. Then determine the total cost of the game after sales tax if the original price is $52. (Remember that the coefficient of g is 1).
Answer:
$58.64
Step-by-step explanation:
The total cost of a game g with 7% sales tax can be represented by the expression
g + 0.07g
From the above question,
g = Original price of the game = $52.
The total cost of game g =
$52 + 0.07 × $52
$52 + $3.64
= $58.64

SAT/ACT If n is divisible by 2,5, and 14, which of
the following is also divisible by these numbers?
A n+7
D n + 20
B n + 10
E n + 70
C n + 14
Answer:
Option E : n+70 is the correct answer.
Step-by-step explanation:
Given that:
n is divisible by 2,5 and 14.
We have to add a number to n which will make the resulting number also a divisible of 2, 5 and 14.
Therefore,
We will add a number that is multiple of 2,5 and 14
Here,
7 is not a multiple of 2,5 and 14.
20 and 10 are multiples of 2 and 5 but not 14.
70 is a multiple of 2,5 and 14.
14 is a multiple of 2 and 14 but not 5.
Hence,
Option E : n+70 is the correct answer.
Find the value of x and y
I don’t know how
Answer:
x = 2√30, y = 2√21
Step-by-step explanation:
You can create the following equations:
(1) from the left triangle with sides x, y and 6:
y² + 6² = x²
(2) from the right triangle with sides y, 14 and... lets call it z:
y² + 14² = z²
(3) from the big triangle:
x² + z² = 20²
(4) Combine (2) and (3) to eliminate z:
x² + y² + 14² = 20²
combine (1) and (4) to eliminate x:
y² + 6² + y² + 14² = 20²
simplify
2y² = 20² - 6² - 14² = 168
y² = 84
y = √84 = 2√21
x² = y² + 6² = 84 + 36 = 120
x = √120 = 2√30

Step-by-step explanation:
Elaine opened a savings account with a deposit of $1000. The interest on her account is compounded each year at a rate of 2%. Elaine will not make any additional deposits to or withdrawals from her account. What will be the balance in Elaine's account at the end of 3 years? Round your answer to the nearest whole dollar.
Answer:
$1,061.21
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Present value (PV) = $1,000
Rate of interest compounded yearly (r) = 2%
Time period (n) = 3
So, we can calculate the future value (FV) by using following formula,
Future Value = PV(1 + r)^n
By putting the value, we get
FV = $1,000 ( 1 + 0.02)^3
= $1,000 ( 1.02)^3
= $1,000 ( 1.061208)
= $1,061.21

Arlene's register shows a deposit of 10/4 in the amount of $412.45, an ATM withdrawal on 10/5 in the amount of $80.00, and check #393 on 10/9 in the amount of $348.47. What should the balance be in Arlene's register? Use this bank statement.
A: $571.89
B: $588.49
C: $722.96
D: $726.03
Answer:
B.

Answer: B. $588.49
Step-by-step explanation:
Arlene's ending balance on 10/3 is $604.51
On 10/4 she makes a deposit (+) of $412.45
On 10/5 she makes an ATM withdrawal (-) of $80.00
And on 10/9 a check (-) of $348.47
$604.51+ $412.45- $80.00- $348.47= $588.49

On a highway, a random sample is taken of the speed, in mph, of 50 cars. A mean speed of 61.8 mph is calculated with a margin of error of +2.3 for a 95% confidence interval What is the interval estimate of the population mean?
A) 58.7 <h<64.9
B)59.5<h<61.8
C)59.5<h<64.1
D)61.8<h<64.1
The interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.
What is margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
The interval estimate of the population mean can be found out using the following formula:
[tex]\overline X\pm MOE[/tex]
Here, [tex]\overline X[/tex] is the average mean, and the MOE is the margin of error.
On a highway, a random sample is taken of the speed, in mph, of 50 cars.
A mean speed is 61.8 mphThe margin of error is +2.3 The confidence interval is 95%Put the values in the above formula as,
[tex]61.8\pm 2.3\\59.5,641[/tex]
Thus, the interval estimate of the population mean
[tex]59.5 < h < 61.8[/tex]
Hence, the interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.
