Whats is the slope of line that is perpendicular to the line y= -9x + 7
Answer: 1/9
Step-by-step explanation:
The slope of this line is -9. The slope of the perpendicular line is the opposite reciprocal. The reciprocal of -9 is -1/9, the opposite of that is 1/9
The volume of a cylinder is 225π cm³ and its height is 9 cm.
What is the length of the cylinder's radius?
Enter your answer in the box.
cm
Answer:
5cm
Step-by-step explanation:
Given data
volume = 225π cm³
Height= 9cm
r= ???
Volume of cylinder
v=πr^2h
substitute
225π= π*r^2*9
225= r^2*9
r^2= 225/9
r^2= 25
r= √25
r= 5cm
Hence the radius is 5cm
If you are making a cake for a work potluck, and the recipe calls for 2 cups of flour to serve 8 people, how many cups of flour will you need in order to make a large enough cake to serve 30 people?
Answer:-
7.5 cups of flour is required for 30 people
Step-by-step explanation:-
2 cups = 8 people
x cups = 30 people
[ Cross multiply ]
=> 2×30 = x × 8
=> (2 × 30)/8 = x
=> 60/8 = x
=> 7.5 cups = x
Thus, for 30 people 7.5 cups of flour is required.
Hope this helps you.

Step-by-step explanation:
67 × 100 = 6700
67 × (10 x 10) Yes
10 × 10 = 100
67 × 100 = 6700
67 × (10 × 10 × 10) No
10 × 10 × 10 = 1000
67 × 1000 = 67000
670 × 10³ No
10³ = 1000
670 × 1000 = 670000
670 No
670 ≠ 6700
6700 Yes
6700 = 6700
67000 No
67000 ≠ 6700

Translate the sentence into an equation. Five more than the quotient of a number and 6 is equal to 2. Use the variable w for the unknown number.
Answer:
The equation that represents the sentence is W + 6 + 5 = 2.
Step-by-step explanation:
Since it is required to propose an equation that reflects that five more than the quotient of a number and 6 is equal to 2, using the variable W for the unknown number, the following equation must be performed to determine what the unknown number is:
W + 6 + 5 = 2
W = 2 - 5 - 6
W = -9
Therefore, the unknown number is -9.

68-3x=84-7x
simplify by adding 7x to each side
68+4x=84
simply further by subtracting 68 from each side
4x=16
divide both sides by 4
x=4
angle WXU=68-3x
substitute for x
angle WXU=68-3(4)=68-12=56 degrees

Find the probability.
There are three nickels, four dimes, and five quarters in your pocket. You randomly pick
a coin. It is a nickel or a dime.
Answer:
0.583
Step-by-step explanation:
You have a total of 12 coins in your pockets (3 nickels + 4 dimes + 5 quarters).
There are 7 nickels/dimes (3 + 4), meaning you have a 7/12 chance of picking either a nickel or a dime.
7/12 simplifies to 0.583.
You have a 0.583% chance of picking either a nickel or a dime.

Evaluate the following expression for b = -10.
2 (b - 5) + 4
Answer:
−26 and (−1)×2×13=-26
Step-by-step explanation:
2(−10−5)+4
Subtract 5 from −10 to get −15.
2(−15)+4
Multiply 2 and −15 to get −30.
−30+4
Add −30 and 4 to get −26.
−26
Answer:
-26
Step-by-step explanation:
We substitute b for -10, so 2 ((-10) - 5) + 4
Using PEMDAS, we do the parenthesis first: 2 ((-10) - 5) + 4 = 2 (-15) + 4
Then we multiply: 2 (-15) + 4 = (-30) + 4
And finally, we add: (-30) + 4 = -26

Write an equation of the line that passes through the pair of points.
(0, – 4), (5, – 4)
Answer:
[tex]y = -4[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (0, -4)[/tex]
[tex](x_2,y_2) = (5, -4)[/tex]
Required
Determine the equation
First, calculate the slope using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-4 - (-4)}{5 -0}[/tex]
[tex]m = \frac{-4 +4}{5}[/tex]
[tex]m = \frac{0}{5}[/tex]
[tex]m = 0[/tex]
The equation is then calculated using:
[tex]y = m(x -x_1) + y_2[/tex]
This gives:
[tex]y = 0(x - 0)-4[/tex]
[tex]y = 0-4[/tex]
[tex]y = -4[/tex]

A student investigates force and motion. She measures the mass of four wood blocks and places the blocks on a smooth surface. She will push each block with an equal amount of force and measure how far each moves with a ruler. Then, she will place the blocks in order based on how far they move when pushed. Which best predicts her results in order, from the block that moves the farthest to the block that moves the least?
Block Mass (g)
1 45
2 25
3 35
4
Answer:
4, 2, 3, 1
Step-by-step explanation:
Blocks that weigh heavier won't go as far because friction will get to much and the weight and air resistance is bigger on a bigger block, therefore it would slow to a stop further behind te lesser weight ones

Five increased by the quotient of x and six is what?
Answer:
[tex]5+\frac{x}{6}[/tex]
Step-by-step explanation:
When we say the quotient of x and six, that means x divided by 6, or x/6, and since is says 5 is increased by this amount, we must add x/6 to 5 and get 5+x/6.
Answer:
i think 6 is divider
6 divide by a one number it give as 5

Use the table to write a linear function that relates Y to X
Answer:
y = 3/4x + 10
Step-by-step explanation:
The equation of a line is y = slope * x + y-intercept
To find the slope, you choose two points and do (y1-y2)/(x1-x2): Point 1 can be (4,13) and point 2 can be (8,16) so, slope = (13-16)/(4-8) = -3/-4 = 3/4
The y-intercept is the value of y when x is 0, so it would be 10.
Put it together and you get y = 3/4x + 10
