Answer:
122 employees
Step-by-step explanation:
So, first you have to find 22% OF 100 WHICH IS 22. (100x0.22= 22) Then, since they have to lay off 22% more people you add the 22% of 100 (22) to the 100. (100+22=122) This means that they have laid off 122 employees this year. I hope this helps!
Of all 840 sixth grade students in a math school, 700 participated in the math Olympiad. Of all 910 fifth grade students, 745 participated in it.From which grade did more students participate in the Olympiad?
Answer:Sixth grade
Step-by-step explanation:
Given
There are [tex]840[/tex] sixth grade students out of which [tex]700[/tex] Participated in math olympiad
also no of fifth grade students[tex]=910[/tex]
Fifth graders who participated in math olympiad [tex]=745[/tex]
Since [tex]745>740[/tex]
There are more fifth graders in Olympiad [Numerically]
Percentage wise
Percenteage of sixth graders who participated in Math olympiad[tex]=\dfrac{700}{840}\times 100=83.33\ \%[/tex]
Percenteage of Fifth graders who participated in Math olympiad[tex]=\dfrac{745}{910}\times 100=81.86\ \%[/tex]
So, a greater Population of Sixth graders participated in math olympiad compared to Fifth graders as [tex]83.33\ \%>81.86\ \%[/tex]

Albert uses 4One-half ounces of paint on a sculpture. His cousin Tony uses 0.8 as much paint as Albert on a portrait.
Together, how much paint do Tony and Albert use?
3.6 ounces
5.3 ounces
8.1 ounces
8.2 ounces
PLEASE AWNSER ASAP WITH GIVE BRAINLEST IF U DO
Answer:
3.6 ounces.
Step-by-step explanation:
4 one half ounces = 2 ounces of paint.
So Albert uses 2 ounce and Tony uses 2 * 0.8 = 1.6 ounces.
So together they use 2+ 1.6 = 3.6 ounces.
Answer:
8.1 ounces

if a cylinder has a volume of approximately 125.6 cubic cm and has a height of 10cm what is the length of the radius
Answer:
radius = 4 cm
Step-by-step explanation:
To find the length of the radius, we will follow the step below;
First, write down the formula for finding the volume of a cylinder
v=πr²h
where v is the volume of a cylinder
r is the radius and
h is the height of the cylinder
from the question given,
v=125.6 and h = 10 cm
we can now proceed to insert the values into the formula and solve for r
note that π is a constant which is equal to 3.14
v=πr²h
125.6 =3.14×r×10
125.6 =31.4 r
Divide both-side of the equation by 31.4
125.6/31.4 =31.4 r/31.4
4 = r
r =4 cm
The length of the radius = 4 cm

What expression represents the amount of money Brittney has? What expression represents the amount of money that Brittney and Sun have together? What is the equation described in this problem?
Sun's money = x
Brittney's money = 2x
x + 2x = $60
3x = $60
3x/3 = 60/3
x = 20
So amount that Brittney has is 2x.
The amount they have together is 3x
The equation that describes the problem is 3x = $60
Answer:
Brittney has twice as much money as Sun. Together, they have $60. Let x represent the amount of money Sun has.

while hiking you see a 100ft observation tower on top of a 1100ft hill. The angle of elevation to the top of the tower is 6. How far away is the tower?.
Answer:692.82 ft
Step-by-step explanation:
Given
Height of tower is [tex]h=100\ ft[/tex]
Tower is mounted at the top of [tex]H=1100\ ft[/tex] hill
angle of elevation [tex]\theta =60^{\circ}[/tex]
Using figure we can write
[tex]\tan \theta =\dfrac{h+H}{\text{Distance}}[/tex]
[tex]\tan 60^{\circ}=\dfrac{100+1100}{\text{Distance}}[/tex]
[tex]Distance =\frac{1200}{\tan 60^{\circ}}[/tex]
[tex]Distance=\frac{1200}{\sqrt{3}}[/tex]
[tex]Distance=692.82\ ft[/tex]

x < - 5 → A
An angle measuring 32 degrees has a complement that measures ( 2x-16 ) degrees. What is the value
Answer:
x=37
Step-by-step explanation:
Complementary angles add up to 90 degrees.
Let's first find the measure of the complement.
90-32=58
Now we can set the numerical value of it equal to the expression it gave us.
2x-16=58
We have to isolate x.
Lets add 16 to both sides
2x=74
Divide both sides by 2.
x=37
what is the next term of the geometric sequence? 5,10,20
Answer:

A 48-inch board is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece. The shorter piece is ______
inches long.
Answer:
12 inches long
Step-by-step explanation:
So you have the ratio x : 3x
4x = 48
x = 12
Plug in:
12 * 1 = 12
The length of the shorter piece is 12 inches if the 48-inch board is cut into two pieces. One piece is three times the length of the other.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
A 48-inch board is cut into two pieces. One piece is three times the length of the other.
Let x and y be the length.
x = 3y
x + y = 48
3y + y = 48
y = 12 inches
x = 36 inches
Thus, the length of the shorter piece is 12 inches if the 48-inch board is cut into two pieces. One piece is three times the length of the other.
