A rectangular wall in Andrew's house has the dimensions shown. If
Andrew plans to hang two rectangular paintings that each measure 4.5
feet by 3 feet, find the area of the wall that will not be covered by the
paintings
12 ft
18 ft
a. 216 square feet
b. 189 square feet
c. 243 square feet
d. 156 square feet
Answer:
b. 189 square feet
18 X 12 = 216 square feet
4.5 X 3 = 13.5
13.5 X 2 = 27
216 - 27 = 189 square feet

Jamie is helping out in the school library. He needs to figure out how many shelves the library staff should order for a new reading corner. There are 378 books for the reading corner. Each shelf holds 50 books. The librarian wants to put all the books on shelves. How many shelves should the library order?
Answer:
8 shelves
Step-by-step explanation:
First do 378 divided by 50 then you when you get your answer (with remaining numbers) you add one more book case so 378 divided by 50 is 7 then you have a remainder 28 so add another shelf which is now 8 shelves!
if two angles form a linear pair and the measure of one angle is 47 degrees, what is the measure of the other angle
Step-by-step explanation:
Since we know that as the angles are in linear pair then their sum equals to 180°
Given
One angle = 47°
Let the other angle be x then
x + 47° = 180° {being linear pair }
x = 180° - 47°
Therefore x = 133°
The measure of the other angle is 133°
Hope it will help :)❤
Answer:
133°
Step-by-step explanation:
they form 180° together, so 180-47=133°
On a road map with a scale of 1 cm. : 110 mi., the distance between two cities measures 4.5 cm. What is the actual distance between these two cities?
Answer:
465 miles
Step-by-step explanation:
So you have the ratio 1 cm: 110 mi, so you can multiply both sides of this ratio by 4.5 to get
4.5 cm: 465 mi
14. Two sides of a parallelogram are in the ratio 5 : 3 and its perimeter is 48 cm. Find
the length of each of its sides.
Perimeter of the parallelogram = 2( length + breadth)
Solution :-Let the length and breadth be 5x and 3x
2(5x + 3x) = 48cm
2(8x) = 48cm
x = 48/16
x = 3cm
Length = 5x = 5×3cm = 15cm
Breadth = 3x = 3×3cm = 9cm
We know that,
In parallelogram Opposite sides are equal
Hence, The sides of the Parallelogram are 15cm, 9cm, 15cm and 9cmFind the value of x.

Can someone please help me?
Answer:
Answer choice D
Step-by-step explanation:
So we need to get r to the right side. First we can multiply by 3 to get rid of the fraction:
3V=4[tex]\pi[/tex][tex]r^{3}[/tex]
Then we can divide both sides by 4[tex]\pi[/tex] to get r by itself:
[tex]\frac{3V}{4\pi } = r^{3}[/tex]
Then cube both sides:
[tex]\sqrt[3]{\frac{3V}{4\pi } } =r\\[/tex]

?
Answer
22
Step-by-step explanation:
24%=24/100, she finished 24% of her run and of means to multiply so 24/100 x93= 22.32. 22.32 rounded to the nearest tenth is 22 so 22 minutes is the amount of time that has gone by :)
write an equation perpendicular to 4x + 8y = 3 and contain the point (5,7) in slope-intercept form
Answer:
y=2x-3
Step-by-step explanation:
The slope-intercept form of the original equation would be y=3/8−x/2
Therefore, the slope of the perpendicular line would be m=2
Then, the y-intercept would be 7=(2)x(5)+a
A=-3
Answer:
y=2x+3

Sophie had two different coupons for the book store, 15% off coupon or the $2.50 off coupon. The store only allows you to use one coupon at time. The book she wanted was $12. Which is a better coupon for sophie to use and why
Answer:
$2.50 coupon is better as it gives a cheaper sale price.
Step-by-step explanation:
Price of good = $12
Sale price = price of good - coupon
Coupon 1 :
$2.50
Sale price = $12 - $2.50 = 9.50
Coupon 2:
15% off
Sale price =. (100 - 15)% * 12
= 0.85 * 12
= $10.2
Two glasses of milk and 3 snack bars have a total of 63 carbohydrates (carbs), and 4 glasses of milk and 2 snack bars have a total of 82 carbs. Determine how many carbs are in one glass of milk and in one snack bar.
Answer:
Glass of milk=15 carbs
One snack bar=11 carbs
Step-by-step explanation:
×2 2m+3s=63.......................1
×1 4m+2s=82..............2
4m+6s=126
4m+2s=82
Cancel out the 4ms
6s=126
2s=82
minus top and bottom equations and remain with
4s= 44
s=44/4
s=11 ∴ one snack bar is 11 carbs
subs s=11 into equation 1
2m+3s=63
2m+3(11)=63
2m+33=63
2m=63-33
2m=30
m=30/2
m=15 ∴one glass of milk is 15 carbs

Answer:
If [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we get [tex]\mathbf{f(a+2)=\frac{3a^2+27a+46}{a+2}}[/tex]
Step-by-step explanation:
We are given the function: [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we need to find the value of f(a+2)
For finding the value of f(a+2) we will put x= a+2
We have [tex]f(x)=3(x+5)+\frac{4}{x}[/tex]
Put x = a+2
[tex]f(a+2)=3(a+2+5)+\frac{4}{a+2}\\Solving:\\f(a+2)=3(a+7)+\frac{4}{a+2}\\Taking\:LCM\\f(a+2)=\frac{3(a+7)(a+2)+4}{a+2}\\f(a+2)=\frac{3(a^2+2a+7a+14)+4}{a+2}\\f(a+2)=\frac{3(a^2+9a+14)+4}{a+2}\\f(a+2)=\frac{3a^2+27a+42+4}{a+2}\\f(a+2)=\frac{3a^2+27a+46}{a+2}[/tex]
So, If [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we get [tex]\mathbf{f(a+2)=\frac{3a^2+27a+46}{a+2}}[/tex]
