How does an underestimate relate to rounding factors before estimating?

Answers

Answer 1
when both factors in a multiplication problem are rounded up to estimate the product, the estimate is an overestimate.
Answer 2

When you round up, you overestimate because now numbers are bigger than before rounding. In a similar way, when you round down, you underestimate. And, when you round down some factors and round up others, it is hard to tell whether the estimate is an overestimate or an underestimate.

A real world problem for the equation 0.75x - 18.50 = 0.65x

Answers

Diana had chocolate, and ate some, leaving 0.75 of it for Sarah. 

Sarah ate 18.5 grams of it and return the rest to Diana, which was 65% of the original chococate. 

how much chocolate did Diana have at the beginning?

and the solution is: 

0.75x-18.50=0.65x 

0.75x-0.65x=18.50
0.1x=18.50
x=185

so Diana had 185 grams of chocolate.

Answers

x^2 = 36...take the square root of both sides, eliminating the ^2
x = (+-) square root 36
x = (+-) 6

so x = -6 and x = 6

answer is : its the one where a dot is shown on 6 and another dot on -6, and are labeled as p and q ,respectfully
Sorry for the late answer but the answer is B because 6 x 6 is 36. The reason I thing its B is because the question is only asking for positive 36.

7.24 divided by 7 rounded to the nearest tenth

Answers

Final answer:

To divide 7.24 by 7 and round to the nearest tenth, you divide 7.24 by 7, which gives you approximately 1.034285714. The final answer, rounded to the nearest tenth, is 1.0.

Explanation:

To divide 7.24 by 7 and round to the nearest tenth, we divide 7.24 by 7, which gives us approximately 1.034285714. To round to the nearest tenth, we look at the digit in the hundredths place, which is 4. Since 4 is less than 5, we do not round up. Therefore, the final answer, rounded to the nearest tenth, is 1.0.

Final answer:

The division of 7.24 by 7 results in 1.0342857. Rounding this to the nearest tenth, considering the value in the hundredths place is less than 5, the final answer is 1.0.

Explanation:

The question of 7.24 divided by 7 rounded to the nearest tenth deals with basic division and rounding numbers. When you divide 7.24 by 7 using a calculator, you get 1.0342857. To round this to the nearest tenth, we look at the number directly after the tenths place, which is 3 (in the hundredths place). Since 3 is less than 5, we do not round up. Therefore, the answer is 1.0 when rounded to the nearest tenth.

A mechanic repairs Mr. Estes car the amount for parts is $48 and the rate for the mechanic is $40 per hour. Write and solve an equation to find the total cost of repairs to Mr. Estes car if the mechanic works for 1.5 hours

Answers

y = 48 + 40h....where y is the total cost and h is the number of hrs worked

so if he worked 1.5 hrs....h = 1.5

y = 48 + 40(1.5)
y = 48 + 60
y = 108 <===

Final answer:

To calculate the total cost of repairs to Mr. Estes's car, add the fixed cost of parts ($48) to the labor cost ($40 per hour for 1.5 hours), resulting in a total cost of $108.

Explanation:

To find the total cost, we need to consider both the fixed cost (cost of parts) and the variable cost (mechanic's labor charged per hour).

The fixed cost for parts is $48, and the mechanic charges $40 per hour.

If the mechanic works for 1.5 hours, we can calculate the total cost using the equation:

Total Cost = Cost of Parts + (Hourly Rate × Hours Worked).

Substituting the given values into the equation, we get:

Total Cost = $48 + ($40 × 1.5)

= $48 + $60

= $108

Therefore, the total cost of repairs to Mr. Estes's car is $108.

determine translation

Answers

The translation moved point B(-5, -2) to B'(6, -5). Although a graph isn't necessary, it helps visualize what happened.

What happened to the x-coordinate of B?  It changed from -5 to 6, an INCREASE of 11.  So point B moved 11 units to the RIGHT.

What happened to the y-coordinate of B?  It changed from -2 to -5, a DECREASE of 3.  So point B moved 3 units DOWN.

what is the exact length of the diagonal of a 10 cm by 15 cm rectangle?

Answers

To solve this, use pythagorean theroem:

a^2 + b^2 = c^2

Since the diagonal is across from the right angle, it is represented as c.

10^2 + 15^2 = c^2
100 + 225 = c^2
325 = c^2
sqrt 325 = c

Converting to simplest radical form:
5 * sqrt 13 = c

336.752 divided by 31

Answers

it    is   originally 10.829677419 so rounding to the nearest tenth would be 10.9

Answer:

Round to the nearest tenth  336.752 divided by 31 is 10.9

Step-by-step explanation:

Consider the provided information.

336.752 divided by 31

This can be written as:

336.752 ÷ 31

Divide the number as shown:

[tex]\frac{336.752}{31}[/tex]

[tex]10.862968[/tex]

Now we need to round it to the nearest tenth.

According to the place value:

Tens   Ones   Decimal point   Tenths   Hundredths

 10         1                    .                0.1           0.01

According to place value tenths place is just after the decimal point so round the number to just after decimal point.

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, then no need to change the rounding digit.

If 5, 6, 7, 8, or 9 follow the number, round it up by one number.

Here, the number at the hundredths place is 6 so round it up.

Thus, the  round to the nearest tenth is 10.9

a farmer made a square chicken coop with a length of 6 and a half metres. determine the area of the chicken coop

Answers

Final answer:

The area of the chicken coop is 42.25 square meters

Explanation:

To determine the area of the chicken coop, we need to know the length of one side of the square. In this case, the length is given as 6 and a half meters. To find the area of a square, we square the length of one side. So, in this case, the area of the chicken coop is (6.5) * (6.5) = 42.25 square meters.

The process involves squaring the length of one side of the square to find the area. This fundamental formula is applicable not only to squares but also to rectangles, where the area is calculated as the product of the length and width. Understanding these basic geometric principles allows for accurate measurements and calculations in various real-world scenarios, such as determining the area of structures like the chicken coop in your example.
