Answer:
2 hours
Step-by-step explanation:
Given
[tex]Contractor: 81x + 108[/tex]
[tex]Electronic\ Store: 103x + 64[/tex]
Required
Determine the hours when the charges are the same
To do this, we simply equate both expressions:
[tex]Contractor = Electronic\ Store[/tex]
[tex]81x + 108 = 103x + 64[/tex]
Collect Like Terms
[tex]81x - 103x = 64 - 108[/tex]
[tex]-22x = -44[/tex]
Divide both sides by -22
[tex]x =2[/tex]

Write a real world problem for the following equation:
80-3x=53
Answer:
x=9
Step-by-step explanation:
Step 1: Simplify by both sides of the equation.
80-3x=53
80+-3x=53
-3x+80=53
Step 2: Subtract 80 from both sides.
-3x+80-80=53-80
-3x=-27
Step 3: Divide by both sides by 3.
-3x/-3 = -27/-3
x=9

Find tan 0, where 0 is the angle shown.
Give an exact value, not a decimal approximation.
Answer:
[tex] \frac{12}{5} [/tex]
Step-by-step explanation:
In order to find tan of theta, we need to find the side that is opposite of the angle and the side adjacent to the angle.
We are given the side that is adjacent to the angle which is 5.
We are not given the side opposite of the angle.
We can use the pythagorean theorem to find the missing side since we have a right angle.
13 is the hypotenuse and 5 and the missing side are legs so our equation look like
[tex] {5}^{2} + {x}^{2} = {13}^{2} [/tex]
[tex]25 + {x}^{2} = 169[/tex]
[tex] {x}^{2} = 144[/tex]
[tex]x = 12[/tex]
so our missing side length is 12.
Now using tan formula,
[tex] \frac{opp}{adj} [/tex]
our exact value is
[tex] \frac{12}{5} [/tex]

A grocery store clerk put only packages of glazed donuts and packages of chocolate donuts on a shelf. The ratio of the number of packages of chocolate donuts to the total number of packages on the shelf was 5 to 12. Which number could be the number of packages of glazed donuts the clerk put on the shelf?
Answer:
7 packages of glazed donuts
Step-by-step explanation:
A grocery store clerk put only packages of glazed donuts and packages of chocolate donuts on a shelf. The ratio of the number of packages of chocolate donuts to the total number of packages on the shelf was 5 to 12.
From the ratio that is given as
The number of packages of chocolate donuts = 5
The total number of packages = 12
The number could be the number of packages of glazed donuts the clerk put on the shelf is calculated as
Total number of packages - Number of chocolate donuts
= 12 - 5
= 7 packages of glazed donuts

What are the coordinates of the image D(0.5, R) (3, 5) where R(1, –3) is the center of dilation?
Answer:
(2 , 1)
Step-by-step explanation:
dilation center: (1 , -3)
scale factor: 1/2 (0.5)
Final coordinate (x' , y') is the mid-point of segment (3 , 5) and (1 , -3)
x' = (3+1)/2 = 2
y' = (5 + -3) / 2 = 1

Answer:
b=12
Step-by-step explanation:
3b +24= b +48
-24 -24
3b = b+ 24
-b -b
2b = 24

Choose THE correct option. 25. Write the elements of the given set A A= { x|x is a square number less than 5}
1) 2
2) 4
3) 1
Answer:
A = (1, 4)
Step-by-step explanation:
Given :
Square numbers include : 1² = 1 , 2² = 4 , 3² = 9 , 4² = 16 ,...
x|x square numbers less than 5
1² = 1
2² = 4
Therefore all square number less Than 5 are ; 1, 4
Hence,
Set A = (1, 4) where, x|x square numbers less than 5
A = (1, 4)

Betsy has $4.25 and her brother has $16.00 they want to buy two water guns that cost $12.99 each and a bag of water balloons that cost $4.79. Do they have enough money if so how much money will they have left over. If not how much more money will they need?
Answer:
No they don't have enough money, they need $10.52
Step-by-step explanation:
So first, you will add 4.25+ 16.00 = $20.25 < This is the amount they have.
Second, they want two water guns so 12.99 x 2 = 25.98 < This is the price for the water guns.
Then, add the price of the water ballons to the guns which is $30.77 < This is the cost for everything they want to buy.
Subtract $30.77 from $20.25 to recieve the answer of $10.52
Hope this helps!
Help me please just need this last one and I’ll be done please help me if you can
Answer:
58°
Step-by-step explanation:
Start with the equation 2x + 2 + 90 = 148
( I got the 90 from Angle B since it is a right angle.)
Combine like terms 2x + 92 = 148
( 90 and 2 didn't have variables so you could add them together.)
Subtract 92 from both sides 2x + 92 = 148
-92 -92
(The opposite of addition is subtraction.)
Now write out the new equation 2x = 56
Divide both sides by 2 [tex]\frac{2x}{2}[/tex] = [tex]\frac{56}{2}[/tex]
You'll end up with... x = 28
To find the measure of angle BAC, plug in 28 where the x value is 2(28) + 2
This gives you the answer 58°

Colin, Sara and Gordon share some sweets in the ratio 4:3:3. Colin gets 48 sweets. How many
did Gordon get?
Answer:
36
Step-by-step explanation:
So to find the answer we know that the ratio is 4:3:3 if colin gets 48 the ration will be 48:?:?
We have to find the ?
to find the ? we need to divide 48 with 4 and we get 12
now we know that it is 12 we have to multiply all of it with 12 to find Gordon and Sara
So 3 x 12 = 36
So the new Ratio is 48:36:36
Gardon is at the end and the number at the end is 36
So we now know the answer
Please mark as brainliest
Have a great day, be safe and healthy
Thank u
XD
Answer:
36
Step-by-step explanation:
Colin : Sara : Gordon = 4 : 3: 3
Colin's share = 4x
Sara's share = 3x
Gordon's share = 3x
Colin's share = 48
4x = 48 {Divide both sides by 4}
x = 48/4
x = 12
Gordon's share = 3x = 3*12 = 36
