Answers

Answer 1

Answer:

x = 0

Step-by-step explanation:

In order to solve for x, first combine both fractions on the left

To add 4x-2/8 + 3+x/4 first find the least common denominator of 8 and 4

It's 8 so multiply the numerator and denominator of 3+x/4 by 8, you would get:

8x+24/32

Multiply 4x-2/8 by 4, you will get:

16x-8/32

Now you can add 16x-8/32 + 8x+24/32, you would get:

24x+16/32

Now you can start to solve for x

Your new equation is 24x+16/32 = 1/2

To solve for x, first multiply diagonally, then solve like a regular equation.

Multiply 24x+16 by 2 to get 48x+32

Then multiply 32 by 1 to get 32

Your new equation is 48x+32=32

Now subtract 32 by 32 to get 48x=0

Now divide 48 by 0 to get x=0

Left on together the cold and hot water faucets of a certain bathtub takes 6 minutes to fill the tub. If it takes the hot water faucet 15 minutes to fill the tub by itself , how long will it take the cold water faucet to fill the tub on its own ?

Answers

Answer:

10 minutes

Step-by-step explanation:

We have

1/ hot water faucet + 1/ cold water faucet = 1/6

= 1/15 + 1/c = 1/6

1/c = 1/6 - 1/15

Lowest Common Denominator

= 30

Hence:

1/c = 5 - 2/30

1/c = 3/30

1/c = 1/10

Cross Multiply

c = 10 minutes

Hence, it will take the cold water faucet 10 minutes to fill the tub on its own

Joe worked 3 hours overtime.

Step-by-step explanation:

Let t = number of hours overworked

425 + 20 × t = 485

425 + 20t = 485

20t = 485 - 425

= 60

[tex]\frac{20t}{20} = \frac{60}{20}[/tex]

t = 3

Della went to the market to buy 4.5 pounds of sliced fruit in a container. She paid with a $20 bill and a $5 and received $4.67 as change. She paid $1.62 in taxes and for the fruit. What was the cost for one pound of sliced fruit before taxes

Answers

Answer:

the cost for one pound before taxes is $4.52

Step-by-step explanation:

The computation of the cost for one pound before taxes is shown below:

= Paid a bill + amount - change amount

= $20 + 5 - $4.67

= $20.33

Now the cost of one pound would be

= Total amount ÷ number of pounds purchased

= $20.33 ÷ 4.5 pounds

= $4.52

Hence, the cost for one pound before taxes is $4.52

In a paint factory, an old conveyer line has filled 40 barrels of paint, and is filling more at a rate of 1 barrel per minute. A worker just switched on a newer line that can fill 3 barrels per minute. In a little while, the two lines will have filled an equal number of barrels. How many barrels will each line have filled?
Write a system of equations, graph them, and type the solution.

Answers

Answer:

5 minutes

Step-by-step explanation:

let the time after which two lines will have filled an equal number of barrels is 'X' minutes.

so, according to the question after 'X' minutes;

⇒ number of barrels in old conveyer line = number of barrels in new conveyer line

⇒ 40x + 2X = 10X

⇒ X = 5

Answer: for a the answer is 140° and for b x=25°

Step-by-step explanation:

for a, when you have 2 parallel lines cut by a transversal,the corresponding angles are congruent. and the angle140 is congruent to the corresponding angle as they are vertical angles are congruent.

for b, angle x is congruent to the angle that is supplementary to 155 therefore 180-155=25°

Alice has just discovered base 10 cake! She is delighted with how powerful it is. One day, after nibbling on the cake, Alice realizes she is 1 mile tall. Having her head in the sky makes her think about space travel. She decides she wants to visit the moon, which is about 239,000 miles from the earth. How many more ounces of base 10 cake should Alice eat so the top of her head just touches the moon? Give your answer to the nearest hundredth of an ounce.

Answers

Answer:

5.38 ounces

Step-by-step explanation:

Given that :

Alice height = 1 mile

Distance of earth to moon = 239000 miles

Number of base 10 cakes required so they Alice's head just touches the moon ;

Using the relation :

Distance = height per ounce * 10^number of ounces

Height per ounce = 1 mile ;

Let number of ounces = n

Hence,

239000 = 1 * 10^n

239000 = 10^n

Take log of both sides

Log(239000) = n

5.3783979 = n

5.3784 = n

Hence, Alice should take 5.38 ounces of base 10 cakes

m∠5 =

Answers

Answer:

40°

Step-by-step explanation:

180- (90 + 40) = 50°

Angle 1 = 50°

180 - 50 = 130°

Angle 2 = 130°

180 - 130 = 50°

Angle 3 = 50°

180 - (90 + 50) = 40°

Angle 5 = 40°

the two triangles are similar. Therefore, their angles are congruent. Since the tringle was only flipped and made slightly smaller, angles 9 and 5 are corresponding angles. (Both have the same measure of 40°)
