PLEASE HELP!!! asappp i dont understand
Answer:
x = 80°
Step-by-step explanation:
100° and x° are adjacent angles on a straight line and sum to 180° , that is
100° + x = 180° ( subtract 100° from both sides )
x = 80°

PLEASE ANSWER THIS QUESTION!!!
The power, P (watts), of a car engine is proportional to the square of its speed, s (m/s).
When s=35, P=2200.
Work out the power (to 1 DP) when the speed is 40 m/s
Answer:
THE ANSWER!!!!!!!!!!
Step-by-step explanation:
The power, P (watts), of a car engine is proportional to the square of its speed, k%28m%2Fs%29; it means if you have two different powers and speeds, you will have a proportion
P%3Ak%5E2=P%5B1%5D%3Ak%5B1%5D%5E2 or
P%2Fk%5E2=P%5B1%5D%2Fk%5B1%5D%5E2
When given:
k=35, P=2200
Work out the power P%5B1%5D (to 1DP) when the speed is k%5B1%5D=40%28m%2Fs%29
so,
P=2200
k=35
k%5B1%5D=40
and you need P%5B1%5D
2200%2F35%5E2=P%5B1%5D%2F40%5E2
2200%2F1225=P%5B1%5D%2F1600
1.79592=P%5B1%5D%2F1600
1.79592%2A1600=P%5B1%5D
P%5B1%5D=2873.5 watts
Explain why the exponents cannot be added in the products 12 to the third power times 11 to the third power
Answer:
Because the exponent rule that let's the base to the sum of the exponents power equal the base too the x power times the base to the y power states that the bases must be the same. And the bases 12 and 11 are not equal.
1.If P ={ a, b, c, d, e,f g}
Q = { a, c, d, f} and R = { d, e ,f, g, h, i,j}
Then ( P Q) =
2.T ={p,q,r,s,t} . The number of subsets of T is?
Answer:
I think it would be ( a , b , c , d , e , f , g , )
Step-by-step explanation: It is combining both P and Q together in one set but don't add the same member if they are in both set

Lesson 14 Introduction
Solutions of Linear Equations
Use What You Know
You've learned how to solve linear equations and how to check your solution. In this
lesson, you'll learn that not every linear equation has just one solution. Take a look
at this problem.
Jason and his friend Amy are arguing. Jason says that a linear equation always has just one
solution. Amy says that some linear equations have more than one solution. Who's right?
Amy asked Jason to explore solutions to the following equation
2x + 1 + x = 3x - 2)+7
Use the math you already know to solve this problem.
Remember that a solution to an equation is a number that makes the equation true.
To check to see if a number is a solution to this equation, replace x with its value.
a. Is 6 a solution to the equation? Show your work
b. Is -2 a solution to the equation? Show your work. 2X
c. Is 0 a solution to the equation? Show your work.
2(-2) + 1 + (-2) = 3(-2 - 2) + 7
-4 + 1 -2 = 3(-4) + 7
-3 - 2 = -12 + 7

The ratio of Jay age to Hena's age to Sally age is 4:3:6.Jay is 24 years old
(a)Find Sally's age.
(b)What is their total age?
Answer:
1. Write It Out:
Jay 4: Hena 3 : Sally 6
Jay is 24 years old.
2. Solve
So first you find 24/4 to get 6. This means Jays age was divided by 6 to get his ratio number. Showing that Hena's and Sally's is divided by 6 as well to get there ratios. Now what you need to do is mulitipy Hena and Sallys ratio by six to find there age's.
Hena: 3x6= 18 years old
Sally: 6x6= 36 years old
(Jay: 4x6= 24 years old)
Now to find there total age add them up...
18+36+24= 78
A. Sally is 36
B. 78
Answer:
Sally is 36 years old.
their total age is 78 years.
Step-by-step explanation:
[tex]4 + 3 + 6 = 13[/tex]
that's the total ratio
Jay is 24 years old and his ratio is 4
so assume the total age to be
[tex]x[/tex]
[tex]4 \div 13 \times x = 24[/tex]
[tex]4x \div 13 = 24[/tex]
[tex]4x = 24 \times 13 \div 4[/tex]
[tex]x = 78 \: total \: age[/tex]
t
[tex]sally \: age = 6 \div 13 \times 78[/tex]
[tex]sally \: is \: 36years \: old[/tex]

Solve the inequality for the smallest integer that would satisfy the given inequality
-x+2<3x-6
Step-by-step explanation:
-x+2<3x-6
-x-3x< -6-2
-4x < -8
-x < -2
When sign changes , inequality sign changes
x > 2
Step-by-step explanation:
-x + 2 < 3x - 6
8 < 4x
2 < x
so, the smallest integer that makes that true is therefore x = 3.

What are the coordinates of the image of the point (−2, 6) after a clockwise rotation of 90° about the origin?
(−6, −2)
(6, 2)
(2, −6)
The rule is
(x,y)=(y,-x)So
Our coordinate is (-2,6)
Rotated point
(6,-(-2))(6,2)Option B
Answer:
(6, 2)
Step-by-step explanation:
Rotation rules about the origin:
90° clockwise (or 270° counterclockwise): (x, y) → (y, -x)180° clockwise (or 180° counterclockwise): (x, y) → (-x, -y)270° clockwise (or 90° counterclockwise): (x, y) → (-y, x)Therefore, to rotate (-2, 6) clockwise 90° about the origin:
⇒ (-2, 6) → (6, -(-2)) → (6, 2)

Janice buys four boxes of paper clips . She pays with a $ 10 bill and receives $ 6.08 in change . What is the price of one box of paper clips ?
Answer:
$0.73 per paper clip
Step-by-step explanation:
So to start off you want to find out how much she paid for the paper clips. We know that she paid with a 10 dollar bill and she got $6.08 in change. Now just subtract to find the amount.
10-6.08 which is 2.92
So she paid $2.92 for 4 boxes of paper clips.
The question asks for 1 box So you divide.
2.92/4 which is 0.73
The answer is $0.73 per box of paper clip.

Given that point is the midpoint of CD what additional information will allow for the conclusion that AB is a perpendicular
bisector of CD?
1. CE congruent ED
2. AE congruent EB
3. m
4. m
(< mean angle)
Answer:
CE congruent ED
Step-by-step explanation:
A perpendicular bisector is a line segment which perpendicularly intersects another line, thereby dividing it into two equal parts. In fact, the Perpendicular bisector theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the segment’s endpoints.
The perpendicular bisector, AB, bisects CD at a point E, that is, the length CE is equal to ED. And the angle formed between the two lines is 90 degrees.Therefore, the additional pertinent information that allows for the conclusion that AB is a perpendicular bisector of CD is that "CE congruent ED".
Which type of soil holds the most water?
silt
sand
loem
clay
Answer:
Clay
Step-by-step explanation:
Clay soil has small, fine particles, which is why it retains the most amount of water. Sand, with its larger particles and low nutritional content, retains the least amount of water, although it is easily replenished with water. Silt and loam, with medium-size particles, retain a moderate amount of water.

At a sale on winter clothing, Cody bought two pairs of gloves and four hats for $44.00. Tori bought two pairs of gloves and two hats for $28.00. Solve the system to determine the prices of the hats and gloves.
Answer:
$6.00 for pair of gloves and $8.00 for a hat
Step-by-step explanation:
the difference between Tori and Cody is $16.00 its two hats. Then one hat is $8.00
If two hats are $16, two pair of gloves must be $12.00
Then one pair of gloves is $6.00

Charlie is shopping for a jacket that he likes. The jacket, regularly priced at $200, is on sale at Clothes Are Us for $150. Jacket World is offering a 25% discount on the same jacket that regularly sells for $190 at that store. Which statements are correct for this situation?
A) Jacket World's price is $150.00
B) Jacket World has the better deal.
C) Clothes Are Us has the better deal.
D) Both stores are offering a 25% discount on the jacket.
E) The difference in the sale prices at the two stores is $7.50.
The correct options are:-
Choice B) Jacket world has the better deal.
Choice D) Both stores are offering a 25% discount on the jacket.
Choice E) The difference in sale prices at the two stores is $7.50
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
25% = 0.25
25% of $190 = 0.25*190 = 47.50
190 - 47.50 = 142.5
This indicates the price at Jacket World is $142.5 instead of $150
Therefore, choice A is false.
Choice B on the other hand is true because $142.50 at Jacket World is a lower price compared to $150 at Clothes Are Us. Jacket World has the better deal.
Because choice B was shown to be true, there's no way choice C can be true as well. Otherwise, we'd have a contradiction. So we can rule out choice C.
Let's find the percentage discount for Clothes Are Us.
The original price is $200 and its sale price is $150. So you save 200-150 = 50 dollars.
Divide that over the original price to find the discount: 50/200 = 0.25 = 25%
Therefore, Clothes Are Us has the same discount percentage as Jacket World. Both have a 25% discount. Choice D is true.
