The width of a rectangle measures (4.4d-4.3)(4.4d−4.3) centimeters, and its length measures (7.6d+4.7)(7.6d+4.7) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer:
Perimeter, P = (24d+0.8) cm
Step-by-step explanation:
Given that,
Width of rectangle, B = (4.4d−4.3) cm
Length, l = (7.6d+4.7)
Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,
Perimeter = 2(L+B)
P = 2[(7.6d+4.7)+(4.4d−4.3)]
Collecting like terms
P = 2[(7.6d+4.4d)+(4.7−4.3)]
P=2(12d+0.4)
⇒ P = 24d+0.8
So, the expression for the perimeter of the rectangle is (24d+0.8) cm.

The total distance from earth to the sun would be written as 1.0346 x 1022 7 points
miles from earth. What would this be in standard notation? *
Answer:
1.0346 x [tex]10^{22}[/tex]
Since the exponent of the scientific notation is positive, move the decimal point 22 places to the right.
10,346,000,000,000,000,000,000
The standard notation will be 10346000000000000000000.
It is given that total distance from earth to sun is 1.0346 × [tex]10^{22}[/tex]miles.
What will be the standard notation for this ?
What do you mean by the standard notation of a number ?
Standard notation of a number is when a number is written with only number digits i.e., the standard notation for 2 × [tex]10^{2}[/tex] will be 200.
The total distance from earth to the sun would be written as ;
1.0346 x [tex]10^{22}[/tex] miles.
We need to put the decimal point 22 places right ;
So , It can be written as ;
10346000000000000000000
Thus , standard notation will be 10346000000000000000000.

Given that 2 x − 2 y = 23 Find x when y = 9
Answer:
[tex]x=41/2=20.5[/tex]
Step-by-step explanation:
So we have the equation:
[tex]2x-2y=23[/tex]
And we want to find x when y is 9.
So, substitute y for 9 and solve for x:
[tex]2x-2(9)=23[/tex]
Multiply:
[tex]2x-18=23[/tex]
Add 18 to both sides:
[tex]2x=41[/tex]
Divide both sides by 2:
[tex]x=41/2=20.5[/tex]
So, our answer is 20.5
Answer:
20.5
Step-by-step explanation:
2x - 2y = 23
2x - 2(9) = 23
2x - 18 = 23
2x = 23 + 18
2x = 41
x = 20.5

A 525 gram rock contains 25.0% gold.How many grams are gold?
Answer:
131.25 gram is gold
Step-by-step explanation:
Rock = 525 gram
Gold = 25.0% of the rock
To determine how many grams of the rock are gold,
Find 25.0% of 525 gram
= 25/100 × 525
= 0.25 × 525
= 131.25 gram
Gold = 131.25 gram of the rock
Therefore,
131.25 gram of the rock is gold

What is the solution to this equation?
-8x + 4 = 36
O A. x= -4
O B. x = 4
O c. x= -5
O D. x = 5
Answer:
A
Step-by-step explanation:
So we have the equation:
[tex]-8x+4=36[/tex]
Subtract 4 from both sides:
[tex]-8x=32[/tex]
Divide both sides by -8:
[tex]x=-4[/tex]
And we're done!
The answer is A
Answer:
A. x = -4
Step-by-step explanation:
We are given the equation:
-8x+4=36
We want to solve for x. Therefore, we must isolate x on one side of the equation.
4 is being added to -8x. The inverse of addition is subtraction. Subtract 4 from both sides of the equation.
-8x+4-4=36-4
-8x=36-4
-8x=32
x is being multiplied by -8. The inverse of multiplication is division. Divide both sides of the equation by -8.
-8x/-8=32/-8
x= 32/-8
x=-4
Let’s check our solution. Plug -4 in for x and solve.
-8x+4=36
-8(-4)+4=36
32+4=36
36=36
This checks out, so we know our solution is correct.
The solution to the equation is A. x=-4

If six times a number is decreased by fourteen, the result is 124. What is the number
Answer:
[tex]\large\boxed{23}[/tex]
Step-by-step explanation:
Six times a number is decreased by fourteen, the result is 124.
Write an equation that represents this
(6 * x) - 14 = 124
Multiply 6 by x to remove the parenthesis
6x - 14 = 124
Add 14 to both sides of the equation
6x = 138
Divide both sides of the equation by 6
x = 23
The unknown number is [tex]\large\boxed{23}[/tex]
Hope this helps :)
Answer:
138
Step-by-step explanation
6x-14=124
6x=124+14
x=138/6 138/6=23

Edward has deposited $847 in a savings account that earns interest at a rate of 2.2% compounded daily. What will the account balance be in 18 years
Answer:
$1,257.63
Step-by-step explanation:
A= p(1+r/n)^nt
P = principal = $847
r= interest rate = 2.2%
n= 360 per year
t= 18 years
A= p(1+r/n)^nt
= 847(1+0.022/360)^360*18
= 847(1+0.000061)^6,480
= 847(1.000061)^6,480
=847(1.4848)
= $1,257.63
Total balance in 18 years = $1,257.63

Answer:
x = 6
One-fourth x + one-half = one-third x

A full-time employee who works 40 hours per week earns $20.50 per hour. Estimate that person's income. Round 52 weeks to 50 weeks per year, and round the hourly wage to the nearest dollar for the estimate. What is the estimated of annual income?
Given :
Full-time employee who works 40 hours per week earns $20.50 per hour.
To Find :
The weekly income and annual income after round off .
Solution :
Weekly income is given by :
[tex]C =40\times 20.50\\\\C=\$ 820[/tex]
Now , round off of hourly in come to nearest dollar is $21 .
So , new weekly income is :
[tex]C'=40\times 21\\\\C'=\$ 840[/tex]
Now , annual income is :
[tex]A=C'\times 50\\\\A=\$840\times 50\\\\A=\$42000[/tex]
Therefore , weekly income and estimated of annual income is $42000 .
Hence , this is the required solution .
