Given : A rectangular picture frame has a perimeter of 52 inches. The height of the frame is 12 inches.
To Find : The width of the frame .
Solution : Let us take the width of the frame be x . So , we know the formula to find the perimeter of rectangle as ;
[tex]\boxed{\red{\bf Perimeter_{rectangle}=2(l+b)}}[/tex]
Where , l is the length of the rectangle and b is the breadth of the rectangle .
⇒ Perimeter = 2 ( l + b ) .
⇒ 52 in. = 2 ( 12 + x ) in.
⇒ 52 in.= 24in. + 2x .
⇒ 2x =( 52 - 24 ) in
⇒ 2x = 28 in.
⇒ x = 28/2 in.
⇒ x = 14 in.
Hence the width of the rectangle is 14 inches.

a. How many had ridden the bus only?
b. How many had ridden the LRT only?
c. How many had ridden the jeep only?
d. How many did not ride on any of the three modes of transportation?
Answer:

[tex]Total =120[/tex]
[tex]B = 68 \to Bus[/tex]
[tex]L = 78 \to LRT[/tex]
[tex]J =33 \to Jeep[/tex]
[tex]n(B\ n\ L) = 40[/tex]
[tex]n(B\ n\ J) = 20[/tex]
[tex]n(L\ n\ J) = 19[/tex]
[tex]All = 15[/tex]
(a) Bus only
This is calculated using:
[tex]B\ only = B - n(B\ n\ L) - n(B\ n\ J) + All[/tex]
So, we have:
[tex]B\ only = 68 - 40 - 20 + 15[/tex]
[tex]B\ only = 23[/tex]
(b) LRT only
This is calculated using:
[tex]L\ only = L - n(B\ n\ L) - n(L\ n\ J) + All[/tex]
So,
[tex]L\ only = 78 - 40 - 19 + 15[/tex]
[tex]L\ only = 34[/tex]
(c) Jeep only
This is calculated using:
[tex]J\ only = J - n(B\ n\ J) - n(L\ n\ J) + All[/tex]
So, we have:
[tex]J\ only = 33 - 20 - 19 + 15[/tex]
[tex]J\ only = 9[/tex]
(d) None
Let x represents those that took none of the means of transport.
So, we have:
[tex]Total = B\ only + J\ only + L\ only + [n(B\ n\ L) -All] +[n(B\ n\ J) -All] +[n(L\ n\ J) -All] + All + x[/tex]
This gives
[tex]120= 34 + 23 + 9 + [40 -15] +[20 -15] +[19 -15] + 15 + x[/tex]
[tex]120= 115 + x[/tex]
Collect like terms
[tex]x = 120 - 115[/tex]
[tex]x = 5[/tex]

In the diagram, bisects ABC. Find mABD and mDBC
Answer:
mABD=24
mDBC=24
Step-by-step explanation:
First, set up x+15 and 4x-12 as equivalent equations
Subtract x from both sides to get 3x-12=15
Add 12 to get 3x=27
x=9
Plug 9 into the original equations representing the measurements of angles
You should get 24 for both because bisected means both are congruent

The density of a certain material is such that it weighs 5 kilograms for every 8.5 fluid
ounces of volume. Express this density in ounces per liter. Round your answer to the
nearest whole number.
Answer:
701 ounces per liter
Step-by-step explanation:
it's from delta math
The required density in ounces per liter is 140 onces per liter.
The density of a certain material is such that it weighs 5 kilograms for every 8.5 fluid ounces of volume.
To determine density in ounces per liter.
Volume is defined as the ratio of the mass of an object to its density.
As given that, t weighs 5 kilograms for every 8.5 fluid ounces of volume.
1 KG = 7.0474 ounces
5kg = 35.247
8.5 fluid of ounces = 0.251 liter
Density is given as,
= mass / volume
= 35.274 / 0.251
= 140 ounces per liter.
Thus, the required density in ounces per liter is s140 ounces per liter.

|10-4x|-2=9
Please help
I'm assuming you're asking for x.
Answer: -1/4 and 21/4
Step 1: Add 2 to both sides of the equation.
∣10−4x∣=9+2
Step 2: You can get two equations from this.
10−4x=11 and -(10-4x)=11−(10−4x)=11
Solve both equations.
1st equation:
−4x=11−10
−4x=1
x=-1/4
2nd equation:
−10+4x=11
4x−10=11
4x=11+10
4x=21
x=21/4
Answer:
[tex]x=-\frac{1}{4} , \frac{21}{4}[/tex]
Step-by-step explanation:
Isolate the absolute value signs by adding 2 to both sides of the equation.
[tex]|10-4x|=11[/tex]Create a positive and negative case to solve for absolute value problems.
[tex]10-4x=11 \\ 10-4x=-11[/tex]Subtract 10 from both sides of both equations.
[tex]-4x=1 \\ -4x=-21[/tex]Divide both sides of each equation by -4 in order to isolate and solve for x.
[tex]x=\frac{1}{-4} \\ x= \frac{-21}{-4}[/tex]Simplify these x-values by canceling out the negative sign (2 negatives = 1 positive).
[tex]x= -\frac{1}{4} \\ x = \frac{21}{4}[/tex]x = -1/4 and 21/4 are the solutions to this equation.
How many values are in the range 35 to 95?
A) 62
B) 61
C) 60
D) 59
Answer:
61
Step-by-step explanation:
==================================================
Work Shown:
a = smallest integer = 35
b = largest integer = 95
c = number of integers between 'a' and 'b' (including both endpoints)
c = b-a+1
c = 95-35+1
c = 61
The +1 is to count the starting value.
Consider the set {1,2,3,4,5}. If we don't have the +1, then we would have 5-1 = 4, but there are actually 5 items here. So we add 1 to fix this.

Answer:
20.75(8)+0.42(15)
Step-by-step explanation:
I did 0.42 because that is the cost per one pansy. While she is getting 8 trees so you multiply the cost of one tree by the number of trees total to get the total cost for all of the trees together. Then 0.42*15 is the total amount of money she will spend on pansies. Once she knows how much she will spend on pansies then she can by the six packs but if she was to buy 2 six packs she would still need to get half a pack of pansies to get 15 because 15 does not go into 6 evenly.

Are these ratios equivalent?
8 large rubber bands : 10 small rubber bands
16 large rubber bands : 20 small rubber bands
Group of answer choices
Yes
No
========================================================
Explanation
The ratio 8:10 simplifies to 4:5 when you divide both parts by 2.
The ratio 16:20 simplifies to 4:5 when you divide both parts by 4
Therefore the two ratios 8:10 and 16:20 are both equal 4:5, so they are equal to one another.
------------
Put another way,
(8 large)/(10 small) = (16 large)/(20 small)
8/10 = 16/20
8*20 = 10*16 ... cross multiply
160 = 160
We get a true equation, so the first equation is true as well.
This shows the ratios are equivalent.
-------------
Or you could have...
(8 large)/(16 large) = (10 small)/(20 small)
8/16 = 10/20
8*20 = 16*10
160 = 160
We get the same conclusion as before.
