Can Someone Explain Thoroughly How I Am Meant To Solve This?

Answers

Answer 1

Answer:

I got x<equal to -11 or x>equal to4

Step-by-step explanation:

x^2+15x+44=0

(x+4)(x+11)=0(Factor left side of equation)

x+4=0 or x+11=0(Set factors equal to 0)

x=−4 or x=−11

Check intervals in between critical points. (Test values in the intervals to see if they work.)

x<−11(Works in original inequality)

−11<x<−4(Doesn't work in original inequality)

x>−4(Works in original inequality)

Answer:

x<−11 or x>−4

When someone donated 14 gallons of paint to Rosendale Elementary School, the fifth grade decided to paint a mural. They split the gallons equally among the four classes.
b. how much paint will three classes use?
c. If 4 students share a 30-square footwall equally, how many square feet of the wall will be painted by each student?
d. what fraction of the wall will each student paint?

Answers

Answer:

Step-by-step explanation:

So, first we can do 14/4 which is 3.5

Each class uses 3.5 gallons

For (B), we can do 3.5 * 3 which equals 10.5 gallons

For (C), we can do 30÷4 which is 7.5 square feet

For (D) they each paint 1/4 of the wall

Given a normal distribution with a mean of 120 and a standard deviation of 12, what percentage of values is within the interval 96 to 144

Answers

Answer:

0.9545

Step-by-step explanation:

Given that :

Mean (m) = 120

Standard deviation (s) = 12

what percentage of values is within the interval 96 to 144

P(96 < x < 144)

P(x < 96)

obtain the standardized score (Z) :

Z = (x - m) / s

Z = (96 - 120) / 12 = - 2

p(Z < - 2) = 0.02275 ( Z probability calculator)

P(x < 144)

obtain the standardized score (Z) :

Z = (x - m) / s

Z = (144 - 120) / 12 = 2

p(Z < - 2) = 0.97725 ( Z probability calculator)

p(Z < - 2) - p(Z < 2) = 0.97725 - 0.02275 = 0.9545

In an election for school president, the loser received 70% of the winner's votes. If 969 votes were cast, how many did each receive?

Answers

Answer:

The ans would be 291 (however we can round this off to 290 as no can partially vote as 0.1)

Step-by-step explanation:

We can easily find the loser's vote by-

70% of 969= 678.9

now, all we need to do is find the winners vote

we know that the total no. of votes= 969 & we know the no. of votes loser got

so, subtracting the losers vote from 969 would give us the remaining no. of votes (the winner's votes)....so,

969-678.9=290.1

we can round this off to 290

TS is an angle bisector. If m∠RTS=x+10 and m∠UTS=2x+5, find m∠RTU.

answer choices below


30°30 degrees

15°15 degrees

80°80 degrees

5°

Answers

Answer:

m∠RTS= 15°, m∠UTS= 15°, m∠RTU= 30°

Step-by-step explanation:

Since TS bisects RTS and UTS, that means the two angles are equal to each other. So let's find x first.

x+10=2x+5, subtract x to both sides

10=x+5, subtract 5 to both sides

x=5

Since RTU is basically RTS plus UTS, let's add the two angles together

x+10+2x+5, combine like terms

3x+15

Then we can plug in 5 for x

3(5)+15

15+15

=30

So, RTU is 30 degrees
