Explain how to use the combine place values strategy to find 223-119

Answers

Answer 1

Answer: Combine place value strategy is useful if you try to subtract a number with bigger digits from a number with a smaller digit in the same place... such as now, where 3 is smaller than 9 in the ones place.

Then we can combine two place values: 23 and 19 and subtruct those. 23-19 is 4 (you can just count up from 19 to 23), so you know that the two will give the result of 04, and then you can proceed to the left: 2-1=1.

so the final result will 104.

Hope I helped:P

A clock tower has a circular clock face with an area of 144pi square feet. What is the diameter of the clock face? Teacher wants to see method using square root and showing step by step work. Please help.

Answers

Answer:

d = 24

Step-by-step explanation:

The area of a circle is given by A = π * r²

We are told the area of the clock is 144π.

Let's clear the formula for the radius:

r² = A / π

r² = 144π / π

r² = 144

r = √144

r = 12

The diameter is two times the radius, d = 2r = 2*12 = 24.

Final answer:

To find the diameter of the clock face, we can use the formula A = πr² and solve for r using the given area. The diameter can then be found by multiplying the radius by 2.

Explanation:

To find the diameter of the clock face, we need to find the radius of the clock first. The area of a circle is given by the formula A = πr², where A is the area and r is the radius. Given that the area of the clock face is 144π square feet, we can set up the equation as follows:

144π = πr²

To solve for r, we divide both sides of the equation by π:

144 = r²

Taking the square root of both sides, we find:

r = √144 = 12

Since the diameter is twice the radius, the diameter of the clock face is 2 times 12, which is 24 feet.

72 - (blank) + 20 = 70 what number is the blank

Answers

$72-x+20=70 \n \n 92-x=70 \n \n -x=-22 \n \n x=22 \n \n blank=22$

$72-x+20=70 \n -x+92=70 \n -x+92-92=70-92$

Divide both sides by -1

$(-x)/(-1) = (-22)/(-1) =22$

Shawn’s pay is $123 for 20 hours of work. Find hourly wage and then calculate the amount of pay for 31 hours.

Answers

Hi hope I help, so first 123×20 which = 2,460 then, 2,460×31 and the answer is 76,260

Final answer:

To find Shawn's hourly wage, divide his total pay by the number of hours worked. To calculate the pay for 31 hours, multiply the hourly wage by 31.

Explanation:

To find Shawn's hourly wage, we divide his total pay by the number of hours worked. Therefore, the hourly wage is $123/20 = $6.15 per hour.

To calculate the amount of pay for 31 hours, we multiply the hourly wage by the number of hours worked. Therefore, the amount of pay for 31 hours is $6.15 * 31 = $190.65.

Convert 7qt/min into gallons per hour

Answers

we first need to turn every thing into the same unit of measure ment

1 gallon=4 quarts
60 minutes=1hour

7*60=420 420 is how many quarts per hour but we want gallons so we want to divide by 4
420/4=105
105 gallons per hour

so
qt=quart
4 quart=1 gallon
1 quart=1/4 gallon
min=minute
60 minutes in 1 hour
1 minute=1/60 hour

so 7 quarts=7 times 1/4 gallons=7/4 gallons
1 minute=1 times 1/60 hours=1/60 minutes

7/4 gallons per 1/60 minutes
(7/4gal)/(1/60h)
we don't really need to divide so multiply the whole thing by (1/60)/(1/60) to clear bottom fraction
(7/4 times 60/1)/(1/60 times 60/1)=(420/4)/(60/60)=(420/4)/(1) =420/4=210/2=105/1=105 gallons per hour

the asnwer is 105 gallons per hour
