Ms. Romero runs a house cleaning business. To save money, she bought a 1-gallon container of concentrated cleaner. She mixed the cleaner with 10 gallons of water. Then, she filled as many 1-pint spray bottles as she could. How many spray bottles did she fill?

Answers

Answer:

88

Step-by-step explanation:

The number of 1-pint spray bottles she can fill with 11 gallons is 88.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 km = 1000 m

1 hour = 60 minutes

We have,

The quantity of cleaner and water mixed.

= 1 gallon + 10 gallons

= 11 gallons

Now,

1 gallon = 8 pint

Multiply 11 on both sides.

11 gallon = 88 pints

Thus,

The number of 1-pint spray bottles is 88.

Delaney has $28.00 and buys a shirt for 14.00. Delaney used the equation 14x = 28 to model her scenario, where x represents the amount of money she has left.

After solving her equation, Delaney says the solution x = 2, means that she has $2.00 left. Is she CORRECT? Why or why not?

Answers

She is incorrect because 14 multiplied by 2 equals 28, which means she wouldn’t have any money left over.

Freddy says that 3/6 - 1/3 - 2/3 because all you have to do is subtract the
numerators and subtract the denominators. Is Freddy correct or incorrect? You may draw
a fraction model to support your thinking.
3. What is the answer to this subtraction problem?
Ovation

Answers

Answer:

Incorrect

The correct answer is 1/6

Step-by-step explanation:

Freddy is incorrect. You are not supposed to subract the denominators. When you are solving the equation you have to find a common denominator. You can only subtract the numerator, and the denominator is the same.

Find the LCM. The LCM in this case is 6.

[tex]\frac{3}{6} -\frac{2}{6}[/tex]

Remember, only subtract the numerators. The denominator will still be 6.

[tex]\frac{1}{6}[/tex]

1/6 is the correct answer. I hope this helps you!

lins family has completed 70% of a trip they have traveled 35 miles how long is the whole trip

Answers

Answer:

The distance of the whole trip is 50 miles.

Step-by-step explanation:

Let the distance of the whole trip be x.

70% x = 35 miles

(70/100)x = 35 miles

x = 35 * (100/70) miles

x = 50 miles

Therefore, the distance of the whole trip is 50 miles.

Hope this helped!

Answer:

50

Step-by-step explanation:

Percantage Lin's family covered = 70 %

The distance they had travelled= 35 miles

The total distance of the trip = 70 / 100 x X = 35

( explanation :  the formula to find the percentage of something is "percentage/ 100 of the total " so we used linear equation.... and so we made use of [this much percentage of "x" or something is this much] )

Line l is a straight line.

Line l is a straight line. 2 line intersect line l to form 4 angles. From top left, clockwise, the angle are: x, y, z, w.

Which statements are true about the angles in the figure? Select two options.
Angle x and angle y are supplementary angles.
Angle W and angle Z are a linear pair.
Angle W and angle Y are adjacent angles.
Angle X and Angle Z are vertical angles.
Angle Z and angle Y are complementary angles angles.

Answers

∠x and ∠y are supplementary angles, ∠w and ∠z are a linear pair, and ∠z and ∠y are complementary angles. Then the correct statements are A, B, and E.

What is an angle?

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

Alternate angle - If two lines are parallel then the third line will make a z-angle and z-angles are equal angles with the parallel lines.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

Line l is a straight line. 2 lines intersect line l to form 4 angles.

From the top left, clockwise, the angle is; x, y, z, w.

Angle x and angle y are supplementary angles. This is correct.

Angle w and angle z are a linear pair. This is correct.

Angle w and angle y are adjacent angles. This is incorrect.

Angle x and Angle z are vertical angles. This is incorrect.

Angle z and angle y are complementary angles. This is correct.

What is the quotient of 5/12 and 1 and 1/6?

Answers

Answer:

5/14

Step-by-step explanation:

The quotient of the given numbers 5 / 12 and 1(1/6) will be ( 5 / 14 ).

What is a quotient?

A quotient in mathematics is the amount created by dividing two numbers. The term "quotient" is used frequently in mathematics and is sometimes known as the integer portion of a division, a fraction, or a ratio.

Given fractional numbers are 5 / 12 and 1(1/6). The quotient will be calculated as below:-

Quotient = ( 5 / 12 ) ÷ ( 1 ( 1 / 6)

Quotient = ( 5 / 12 ) ÷ ( 7 / 6 )

Quotient = ( 5 / 12 ) x ( 6 / 7 )

Quotient = 5 / 14

Therefore, the quotient of the given numbers 5 / 12 and 1(1/6) will be ( 5 / 14 ).
