Answer:
the slope of the line is 4/5
Step-by-step explanation:
an equation parallel to that is y= 4/5 - 3
Slopes are the same = parallel
Answer:
4/5 is the slope of the other line parallel to this y=4/5x+1

What does the office manager do to support his thinking? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. He does a calculation to find the cost of 400 chairs and compares the amount to $ nothing. (Type a whole number.) B. He does a calculation to find the cost of the additional equipment. C. He does a calculation to find the cost of 72 chairs. D. He does a calculation to find the difference between the cost of 400 chairs and the cost of the additional equipment and compares the amount to $ nothing. (Type a whole number.)
Answer:
A. He does a calculation to find the cost of 400 chairs and compares the amount to $11,000Step-by-step explanation:
Step one:
given data
total money =$11,000
number of chairs to be purchased= 400
cost per chair=$72
Step two:
the cost of 400 chairs will be
400*72= $28,800
there will be a deficit of
=28,800-11,000
=$17,800.
This shows that the office manager does not have enough funds for the purchase.
Hence to support his thinking,
A. He does a calculation to find the cost of 400 chairs and compares the amount to the amount he has.
The value of 7 dimes and 1 nickel is
% of a dollar help
Answer:
Answer:
Step-by-step explanatinon:
percent is per hundred
4 dimes is 40 cents or $0.40 or 40/100 of a dollar which is40%
1 nickel and 3 pennies or 8 cents or $0.08 Or 8/100 or 8%
5 quarters and one dime is 135/100 or $1.35 or 135/100 which is 135%
Step-by-step explanation:
Answer:
75%
Step-by-step explanation:
7 dimes and 1 nickel = 7*10 + 5 = 75 cents.
A dollar has 100 cents
75 cents * 1 dollar/100 cents * 100 =
0.75 * 100 = 75%

Ms Tyler has a rectangular patio that she would like to decorate with string lights as shown in the diagram. If she plans to string the lights around the perimeter and across both diagonals how many feet of lights will she need? (READ CAREFULLY)
A: 47 feet
B: 60 feet
C: 80 feet
D: 13 feet
Answer:
the answer is b
Step-by-step explanation:
the answer would be b because you add 12+12 then 5+5 and if you add those together it would be 34 then you would add the diagonal lines together which would be 20 so then you would add 34 plus 26 and then you would get 60 which is b

PLEASE HELP SOON! ALSO INCLUDE A SMALL EXPLANATION as well as the answer ! I am rewarding 100points if you answer quickly
Answer:
the answer is B
f(x)=-2x+3
Step-by-step explanation:
to get the -2x I did --->
pick two points I used (0,3) and (1,1) and used the equation [tex]\frac{y2-y1}{x2-x1}[/tex]
where y2 would be 1 and y1 would be 3
and where x2 would be 1 and x1 would be 0
so you would put the numbers in the equation which would look like[tex]\frac{1-3}{1-0}=\frac{-2}{1}[/tex] and equal -2 which would be -2x in the answer
And the +3 is the y-intercept
Help even tho it’s multiple choice make sure you are correct... I beg you lol
Answer:
The equation of the line is:
[tex]y=(-\frac{1}{2})x+1[/tex]
Therefore, option a is the correct answer.
Step-by-step explanation:
Given the points
(-2, 2)(4, -1)Finding the slope
[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:2\right),\:\left(x_2,\:y_2\right)=\left(4,\:-1\right)[/tex]
[tex]m=\frac{-1-2}{4-\left(-2\right)}[/tex]
[tex]m=-\frac{1}{2}[/tex]
As the point-slope form of the equation of the line is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
substituting the values [tex]m=-\frac{1}{2}[/tex] and the point (-2, 2)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-2=\frac{-1}{2}\left(x-\left(-2\right)\right)[/tex]
[tex]y-2=\frac{-1}{2}\left(x+2\right)[/tex]
[tex]y-2=-\frac{1}{2}\left(x+2\right)[/tex] ∵[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]
Add 2 to both sides
[tex]y-2+2=-\frac{1}{2}\left(x+2\right)+2[/tex]
[tex]y=(-\frac{1}{2})x+1[/tex]
Hence, the equation of the line is:
[tex]y=(-\frac{1}{2})x+1[/tex]
Therefore, option a is the correct answer.

Find an expression which represents the sum of (-3x-4y)(−3x−4y) and (x+3y)(x+3y) in simplest terms
Answer:
The sum of (−3x−4y) and (x+3y) in simplest terms will be:
[tex]\left(-3x-4y\right)+\left(x+3y\right)=-2x-y[/tex]
Step-by-step explanation:
Given
(−3x−4y)(x+3y)Finding the sum of (−3x−4y) and (x+3y)
[tex]\left(-3x-4y\right)+\left(x+3y\right)[/tex]
[tex]=-3x-4y+x+3y[/tex]
[tex]=-3x+x-4y+3y[/tex]
[tex]=-2x-4y+3y[/tex]
[tex]=-2x-y[/tex]
Therefore, the sum of (−3x−4y) and (x+3y) in simplest terms will be:
[tex]\left(-3x-4y\right)+\left(x+3y\right)=-2x-y[/tex]

6. An ostrich cannot fly, but it is able to run fast. Suppose an ostrich runs east for 7.95 s and then runs 161 m south, so that the magnitude of the ostrich's resultant displacement is 226 m. Calculate the magnitude of the ostrich's eastward component.
Answer:
159 m
Step-by-step explanation:
From the information given:
It was stated that if the ostrich ran towards the east direction in 7.95 s, let say the distance from the starting point is O towards the east side E, let called the distance towards the east side to be OE.
Again, the ostrich then runs in the south direction for 161 m, let the distance be OS.
Also, let the magnitude of the resultant displacement between the east direction to the south direction be ES = 226m.
We are to find, the magnitude of the ostrich's eastward component.
i.e. The distance traveled from the center to the east direction within the time frame of 7.95 s.
Using the Pythagoras rule:
ES² = OE² + OS²
226² = OE² + 161²
226² - 161² = OE²
OE² = 226² - 161²
OE² = 51076 - 25921
OE² = 51076 - 25921
OE² = 25155
[tex]OE = \sqrt{25155}[/tex]
OE = 158.60 m
OE ≅ 159 m
Thus, the magnitude of the ostrich's towards the eastward component. = 159 m.
What is the solution to the linear equation? d – 10 – 2d + 7 = 8 + d – 10 – 3d d = –5 d = –1 d = 1 d = 5
Answer:
1,1/7 or 0.85
Step-by-step explanation:
d-10-2d+7=8+d-10-3d=-5d=-d=d=5
in mathematics there is nothing like 1d,it is d
re-arrange
d-2d-d+3d+5d+d-d=10-7+8-10+5
7d=6
d=6/7
d=1,1/7 or 0.85
Answer:
D=1

Step-by-step explanation:
3(m + 4) = 36
What is m
Answer:
m = 8
Step-by-step explanation:
Step 1: Write the equation neatly. {3 (m + 4) = 36}
Step 2: Distribute 3 to m and 4. {3 x m = 3m} {3 x 4 = 12}
Step 3: Write the new equation. {3m + 12 = 36}
Step 4: Subtract 12 from both sides. {12 - 12 = 0} {36 - 12 = 24}
Step 5: Write the new equation. {3m = 24}
Step 6: Divide 3 from both sides. {3m / 3 = m} {24 / 3 = 8}
Step 7: Write the new equation and you get your answer. {m = 8}
16. Crayola makes 2400 crayons in 4 minutes. How many crayons can they make in 15 minut es? pls help U_U
Answer:
9000
Step-by-step explanation:
they make 600 every minute so in 15 minutes they would make 9000
Answer:
They can make 9000 crayons in 15 minutes.
Step-by-step explanation:
Figure out the ratio:
[tex]\frac{2400}{4}[/tex]
Simplify it to get the total number of crayons that they can make in one minute.
2400/4 = 600
They can make 600 crayons per minute.
Now, you should have a proportion.
[tex]\frac{600}{1}[/tex]
Now, multiply the denominator and numerator by 15 because whatever you do to the denominator you have to do to the numerator.
You should now have your answer.
[tex]\frac{9000}{15}[/tex]
Crayola can make 9000 crayons in 15 minutes.

Can you tell me what X=
Answer:
x = 21 degrees!
Step-by-step explanation:
3x + x + 96 = 180
4x +96 = 180
Subtract 96 from both sides!
4x = 84
Divide by 4 from both sides!
x = 21 degrees
Answer:
x=21°
Step-by-step explanation:
3x+x+96°=180°
4x=180°-96°
4x=84°
x=84°/4
x=21°
