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°
Solve 4 x + 7) = 24.

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)
I need help on the second part where you identify if the examples are equal
Answer:
No equalStep-by-step explanation:
Let's make it simpler:
a/b = x, c/d = y, e/f = zWe have:
(x/y)/z = x/y*1/z = x / (yz) x/(y/z) = x*z/y = xz/yFurther steps
(a/b) / (ce/df) = (ace) / (bdf)(ae/bf)/(c/d) = (ae/bf)*(d/c) = (ade)/(bcf)As you see the end results are different
if r=3 cm,s=4cm find the area of the shaded area?
Answer:
hope it helps.............
Answer:
Step-by-step explanation:
π[tex]S^{2}[/tex]-π[tex]r^{2}[/tex] is equal to the area of the shaded area
π[tex]4^{2}[/tex]-π[tex]3^{2}[/tex]
(put this into your calculator)
this equals to 7π
which approximates to 21.99 [tex]cm^{2}[/tex]
and it rounds to 22 [tex]cm^{2}[/tex]

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.

Josh mixes blue and white paint to make a lighter shade of white. He needs the ratio of blue to white paint to be 3:2 to get the desired color. If he uses 15 drops of blue paint, how many drops of white paint does he need to use
Answer:
15 drops of blue to 10 drops of white paint.
Step-by-step explanation:
multiply 3 by 5 to get 15
multiply 2 by 5 to get 10
so 10 drops of white paint.
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
-5 = -5

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]
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.

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.

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".
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
