Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is [tex]\frac{1}{2}[/tex] x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + [tex]\frac{1}{2}[/tex] x - 30 = 180, that is
[tex]\frac{3}{2}[/tex] x - 30 = 180 ( add 30 to both sides )
[tex]\frac{3}{2}[/tex] x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and [tex]\frac{1}{2}[/tex] x - 30 = [tex]\frac{1}{2}[/tex] (140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
If two radio stations start conmercials at 10am, when will the stations have commercials at the same time? One station plays every 12 minutes the other every 8 minutes.
Answer: If two radio stations start commercials at 10 AM , then at 10:24 AM the stations will have commercials.
Step-by-step explanation:
Given: One station plays every 12 minutes the other every 8 minutes.
The minimum time at which both stations have commercials = lcm (12 and 8 )
12 = 2 x 2 x 3
8 = 2 x 2 x 2
LCM( 12 and 8)= 2 x 2 x 2 x 3 = 24
The minimum time at which both stations have commercials = 24 minutes
If two radio stations start commercials at 10 AM , then at 10:24 AM the stations will have commercials.

Answer:
[tex]\frac{1}{3}[/tex] feet
Step-by-step explanation:
The area of a rectangle is represented by the formula [tex]A = l[/tex] ×[tex]w[/tex], in which [tex]A[/tex] is the area, [tex]l[/tex] is the length, and [tex]w[/tex] is width.
Let's put in what we already know into the formula. We know that the area is [tex]\frac{5}{18}[/tex], so let's substitute that for [tex]A[/tex]. We know that the length is [tex]\frac{5}{6}[/tex], so let's substitute that for [tex]l[/tex]. This gives an equation that looks like this:
[tex]\frac{5}{18} = \frac{5}{6}[/tex] × [tex]w[/tex]
To find the width, all we need to do know is isolate [tex]w[/tex]:
[tex]w = \frac{5}{18}[/tex] × [tex]\frac{6}{5}[/tex]
[tex]w = \frac{30}{90}[/tex]
[tex]w = \frac{1}{3}[/tex]
Thus, the width is [tex]\frac{1}{3}[/tex].

Rebecca bought candy boxes in the shape of a square pyramid to use for party favors. The side length of each box is 3.6 inches, and the height is 4 inches. Rebecca wants to fill each box with 20 pieces of candy. If each piece of candy is 0.8 in.³, will Rebecca be able to fit 20 pieces of candy into each candy box?
Answer:
Yes maybe.
Step-by-step explanation:
Well basically if we find the volume of 20 pieces of candy in all, that would be= 20*0.8= 16 cu.inches
And then if we find the volume of the square based pyramid, that would certainly be= 3.6*3.6*4 that is 51.84
Then lastly, if we do, 51.84 ÷16 the final answer will be 3.24. Which might actually be the answer as the pieces of candy certainly can't pass the limit 20 according to me.

A truck has traveled 75 miles in 1.5 hours of driving. At the same speed, which proportion can be used to determine how long, T (in hours), it would take the truck to travel 325 miles.
Answer: 6.5 hours
Step-by-step explanation:
From the question, we are given the information that a truck has traveled 75 miles in 1.5 hours of driving. The miles pee hour travelled will be:
= 75 / 1.5
= 50 miles per hour
The number of hours that the truck will use to travel 325 miles will be:
= 325/50
= 6.5 hours

Malcolm is filling bags with rice. He starts with a 5 1/4 pound container of rice and fills each bag with 5/8 pound of rice. How many bags of rice can malcolm fill??
Answer:
part 1: Divide 5 1/4 pound by 5/8 pound
part 2: 8 bags
part 3: 2/5 of another bag
Step-by-step explanation:
total number of bags that can be filled equals total rice divided by the amount of rice per bag
=5 1/4 divided by 5/8
=(21/4)/(5/8) turn the mixed number into improper fraction
=(42/8)(5/8) common denominator
=42/5
=8.4 bags, but can only fully fill 8 bags
2/8 pounds of rice are left over after filling 8 bags, and 2/8 pounds is equal to
2/5 of another bag
(2/8)/(5/8)
=2/5 simplify
slope , m = 3 .y -intercept , b =7
Answer:
The slope is 3 and the y-intercept is 7. The equation of the line is 3y - 7.
Step-by-step explanation:
The equation of the line works such that y = mx + b where m is the slope and b is the y-intercept. Thus,
slope = m
= 3
y-intercept = b
= 7

Step-by-step explanation:
Since triangles ABC and DEF are congruent,
Angle D = Angle A.
=> (2y - 5)° = 65°, 2y - 5 = 65, y = 35.
Also side EF = side BC.
=> 2x + y = 90.6, 2x = 90.6 - (35) = 55.6, x = 27.8.
Answer: Y = 35, X = 27.8
Step-by-step explanation:
First you need to find Y. So, you do 2y - 5 = 65. First you add 5 to both sides, this will give you 2y = 70. Then divide both sides by 2 to get y = 35. Then in order to find x we do 2x + y = 90.6. First we change Y to the 35, as that is what y equals, then subtract both sides by 35 to get 2x = 55.6. Then you divide both sides by 2 to get x = 27.8.
Find the slope each line.
5)
Answer:
y=-3/4x + 2
Step-by-step explanation:
Since you already picked up the 2 points in the line, all we have to do is count the number of squares for the rise/run
To get the rise, you go down the first point by -3 (since you are moving down its negative 3) then for the run, you go right by 4 (Since you are moving right you get positive 4)
rise = -3
run = +4
y=mx+b
y = -3/4x + b
Now to find the y intercept, which is "b" in the equation above, you just look at the graph and find out where the y intercept is, in this case, I'd say its about 2.
y = -3/4x + 2

Calculate the total to be repaid on a loan of $4600.00 for 18 months at a
rate of 5%.
Answer:
$4945
Step-by-step explanation:
the interest on the loan can be found by using this formula:
I = P · r · t P = principal, r = interest rate, t= time (in years)
I = 4600(.05)(1.5)
I = 345
Total Amount = Principal plus Interest
Total Amount = 4600 + 345 = $4945

11. The price of a bottle of water at a store decreases from $1.65 to $1.40. Rounded to the nearest
tenth of a percent, what is the percent decrease in the price of the bottle of water?
A. 15.2%
B. 17.9%
C. 45.9%
D. 54.1%
Answer:
A. 15.2%
Step-by-step explanation:
Subtract the new price from the old one to find the dollar amount that the water bottle price was reduced.
[tex]1.65-1.40=0.25[/tex]
The price was reduced by 25 cents, but we need to find the percentage. To do that, we divide the price reduction by the original price.
[tex]0.25/1.65=0.152[/tex]
And then move the decimal place over two spots (multiply by 100)
15.2
Percent decrease in the price of the bottle of water is 15.2% (Approx.)
Given that;Older price of bottle = $1.65
New price of bottle = $1.40
Find:Percent decrease in the price of the bottle of water
Computation:Percent decrease in the price of the bottle of water = [(1.65 - 1.40) / 1.65]100
Percent decrease in the price of the bottle of water = [(0.25) / 1.65]100
Percent decrease in the price of the bottle of water = [(0.25) / 1.65]100
Percent decrease in the price of the bottle of water = 15.2% (Approx.)
