Answer:
56,000
Step-by-step explanation:
The scale drawing is a 1/40 ratio so you multiply 5 by 40 and you get 200. You do 200x280 and you get 56,000.
Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).

Step-by-step explanation:
12 - 3/4 (d + 16) = negative 5
Answer: d=20/3
Step By Step:
Step 1, Simplify:
12-3/4(d+16)=-5
(-3/4)d+(12-12)=-5
(-3/4)d=-5
Step 2, Multiply each side by 4/(-3)
(4/-3)*(-3/4)d=(4/-3)*-5
d=20/3
Answer:
[tex]\bold{d=\frac{20}{3} \ or \ 6.66666666667}[/tex]
Explanation:
[tex]\bold{12-\frac{3}{4}\left(d+16\right)=-5}[/tex]
[ Subtract 12 From Both Sides ]
[tex]\bold{12-\frac{3}{4}\left(d+16\right)-12=-5-12}[/tex]
[ Simplify ]
[tex]\bold{-3\left(d+16\right)=-68}[/tex]
[ Divide Both Sides By -3 ]
[tex]\bold{\frac{-3\left(d+16\right)}{-3}=\frac{-68}{-3}}[/tex]
[ Simplify ]
[tex]\bold{d+16=\frac{68}{3}}[/tex]
[ Subtract 16 From Both Sides ]
[tex]\bold{d+16-16=\frac{68}{3}-16}[/tex]
[ Simplify ]
[tex]\bold{d=\frac{20}{3}}[/tex]
Ann works in a supermarket for $15.00 per hour. If her pay is increased to $18.00, then what is her percent increase in pay?
Answer:
previous salary of Ann=$15
Present salary of Ann=$18
The increase in salary=$18-$15
=$3
%increase in salary=increase in salary/previous salary
=($3/$15)×100%
=20%
Determine the constant of proportionality, k, and interpret it in the context of each problem. 3) The graph shows the relationship between the weight of an object on Earth and the weight of the same object on Venus. (Hope you can see the picture well)
I am pretty sure it would be k=50 (pounds) because it goes up 50 each point goes by 50 pounds between each one. (as seen in the edited graph I made)
Answer:
it would be k=50 (pounds) because it goes up 50 each point
Solve the system x+y=0 −2x−y=8 *Answer should be in ( x , y ) form, will give 40 points *
Answer:
x = -8 and y= 8
(-8,8) is the answer
Answer:
(2,4) (-4,16)
Step-by-step explanation:
Subtract 2 x from both sides of the equation.
y = 8 − 2 x
Substitute 8 − 2 x for y into x ^2 − y = 0 then solve for x .
x = 2 , − 4
Substitute 2 for x into x 2 − y = 0 then solve for y .
y=4
Substitute − 4 for x into x 2 − y = 0 then solve for y .
y=16
Equation form
x = 2 , y = 4
x = − 4 , y = 16
Bryce is making a model building. He raises the walls of the building by 2 centimeters, five times.
By how many centimeters does Bryce raise the walls altogether?
Answer:
10 cm!
I think...it's really basic math so...maybe?
Answer:
10 cm
Step-by-step explanation:
(2 cm)×5 = 10 cm
Bryce raises the walls 10 cm altogether.
__
You could add the raises, but multiplication is easier.
(2 cm) +(2 cm) +(2 cm) +(2 cm) +(2 cm) = 10 cm
A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people prefer eating out?
Answer:
400 people
Step-by-step explanation:
15 = 12
500 = x
Cross multiply
15x = 12 × 500
Divide both sides by 15
[tex]\frac{15x}{15}[/tex] = [tex]\frac{12 * 500}{15}[/tex] (* means multiplication if you do not know)
[tex]\frac{12 * 500}{15}[/tex] = 100 × 4= 400 people
need help ASAP with this ^-^
Answer:
10
Step-by-step explanation:
All you're doing is [tex]\frac{5}{8}[/tex] ×[tex]\frac{16}{1}[/tex] or [tex]\frac{5}{8}[/tex] ×[tex]16[/tex]
-
[tex]\frac{5}{8}[/tex] ×[tex]\frac{16}{1}[/tex]
so 5 × 16 = 80
and
8 × 1 = 8
The fraction becomes
[tex]\frac{80}{8}[/tex]
then you simplify ( in this case divide by the botton number/denominator) to get :

The figure below is made of two identical triangular prisms. What is the volume of the figure?
Answer:
A triangular prism is 1/2 the volume of a rectangular prism with the same dimensions.
V = BH (Base x Width) of a triangular its 1/2BH
The base is 10 x 5, 50 is the base.
The height is 6, and that would be 300 / 2 since it's triangular so its 150 inches squared for one. Since there are 2.
The total volume is 300 inches squared.

How i know is because i did it the other day
Can anyone help me with this answer
Answer:
18
Step-by-step explanation:
If you take a look at it, its quite similar to the example
Since they are using the same dimensions (1.5) you multiply 1.5 x number x 1.5 again
1/8 as a reciprocal is 8
so you do 1.5 x 8 x 1.5 which gives you 18
