Answer:
It is unequal because PEMDAS states that exponents are above multiplication. In this case, it can be simplified to -1 * 7^2, which is -49.
Carolyn was asked to solve the following system of equations. Her work is shown.
What error did Carolyn make? Identify her mistake and explain the error.
1. Carolyn did not subtract 4 from both sides of the equation.
2. Carolyn did not distribute the -2 to both terms
3. Carolyn did not substitute x + 2 for y
4. Carolyn did not substitute 3 for x to find the value of y for the solution
Answer:
Carolyn did not distribute the -2 to both terms
Step-by-step explanation:
This was how Carolyn solved the second step:
[tex]3x-2(x+2)=7\\3x-2x+4=7[/tex]
She did multiply both terms in the parentheses by 2, but she did not change the sign for the 4. It should instead be -4 since a negative number multiplied by a positive number will always make a negative number.
Here is the correct way of solving it:
[tex]3x-2(x+2)=7\\3x-2x-4=7[/tex]

Length of TV is 12π in. The diameter is?
Answer:
Diameter = 54 units
Step-by-step explanation:
Given:
Angle θ = 80'
Length of arc TV = 12π
Find:
Diameter
Computation:
Length of arc = [θ/360][2πr]
So,
12π = [80/360][2πr]
54 = 2r
r = 27
Diameter = 2r
So,
Diameter = 54 units

A salesman earns 7% commission on all the merchandise that he sells. Last month he sold $6000 worth of merchandise. How much commission (in dollars) did he earn last month?
Answer: $420
Step-by-step explanation:
Percentage on commission earned = 7%
Amount of merchandise sold = $6000
Amount of commission earned = Percentage on commission earned × Amount of merchandise sold
= 7% × $6000
= 7/100 × $6000
= 0.07 × $6000
= $420
He earned $420 as commission last month.
A bag contains 25 kg of flour. A baker used 80% of it to bake bread. How much flour,in kg,remained ?
Answer:
5 kg flour remains
Step-by-step explanation:
80% of the original 25 kg comes to 0.80(25 kg), or 20 kg. We convert 80% to its decimal equivalent, 0.80, to get this result
The amount of flour remaing is then (1.00 - 0.80)(25 kg), or 0.20(25 kg) = 5 kg.
5 kg flour remains.
Answer:
25 - 20 = 5 kg
Steps:
25×80/100 = 25×8/10 = 200/10 = 20 kg
25 - 20 = 5 kg

Answer:

Step-by-step explanation:
sin = adjacent ÷ hypotenuse.
sin 45 = x ÷ 23
0.71 = x ÷ 23
0.71 × 23 = x
x = 16.26
~ 16.
Answer:
Step-by-step explanation:
using the Pythagorean theorem a² + b² = c²
in this triangle a = x and b = x so x² + x² = c² c is the hypotenuse
x² + x² = c²
2x² = c² since c = 23 solve for x
x² = c² / 2
x = ± √(c² / 2)
x = ± √(23² /2)
= ± √(529 /2)
= ± √(264.5)
= 16.26 x can't be negative
That is correct but it doesn't answer the question
x = ??? / √xx
sin 45 = √2 / 2 which equals x / 23
√2 / 2 = x / 23
x = 23 (√2 / 2)
= 23 (√2) / 2 divide the √2 numerator and demenator
= 23 (√2)/√2 / (2 / √2)
= 23 / (2 / √2)

Fourteen percent of the town's population is over the age of 65. If there are 320
residents over the age of 65, approximately what is the town's population?
Answer:
2,285.7143
Step-by-step explanation:
There are two ways of doing this.
#1: Take 320, and divide it by the 14%. This should get you how many people are eqivlelent to 1 percent. When I did it out, 320/14 is equal 22.857143...
Remember this is 1%, and we need to find 100%. So we need to multiply the 1%, which was 22.857143, by 100.
This should get you 2,285.7143.
#2 Take your 100%, and divide it by the 14% that make up the 65+ population. This should get you 7.1428571.
Now you just have to multiply this number by the amount of 65+ residents, which is 320. So you should multiply 320x7.1428571.
This should get you the same exact answer, 2,285.7143

Find the volume of the cone.
Either enter an exact answer in terms of 7 or use 3.14 for .
6
5
units
Answer:
[tex]V=471\ \text{units}^3[/tex]
Step-by-step explanation:
Given that,
Radius of the cone, r = 5 units
Height of the cone, h = 6 units
We need to find the volume of the cone. The formula for the volume of the cone is given by :
[tex]V=\pi r^2 h[/tex]
Substitute all the values,
[tex]V=3.14\times 5^2\times 6\\\\V=471\ \text{units}^3[/tex]
So, the volume of the cone is [tex]471\ \text{units}^3[/tex].

Table of height versus width a = , b = , c = , d = , e =
Answer:
a= 6
b= 7
c= 8
d= 7
e= 6
Step-by-step explanation:
The table of height versus width shows that the values represented will be 6, 7, 8, 7, and 6.
How to calculate the values?From the given information, a = 6. Therefore, the value of b will be: = a + 1 = 6 + 1 = 7
The value of c will be:
= a + 2 = 6 + 2 = 8.
The value of d is also the value of b which will be 7. Lastly, the value of e will be 6.
