Thirteen more than three times a number is 25.

Answer:

d. 770

Step-by-step explanation:

35 gallons per min

after 12 mins there is 350 gallons of water

35 x 12 = 420

how much water was in the tank BEFORE the valve was opened

350 + 420 = 770

STORE B BECAUSE LOW RATES IS BETTER THAN HIGH

Answer:

False

Step-by-step explanation:

1/2 - 5/8 - 7/9 = 7/9 - 5/8 - 1/2

Add 5/8 to both sides.

1/2 - 7/9 = 7/9 - 1/2

Factor -1 out of the right side.

1/2 - 7/9 = -1(-7/9 + 1/2)

1/2 - 7/9 = -1(1/2 - 7/9)

1/2 - 7/9 and 7/9 - 1/2 are opposites. Opposites are not equal unless they are both zero.

Answer: False

Answer:

f(4) =11

Answer:

I think that the answer is B.

Step-by-step explanation:

Hope this helps :)

The situation which leads to a unit cost of $4 per hat is 12 hats for $48. Hence, option B is correct.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the data given in the question,

Cost of one hat = $4

Cost of 12 hat = $4 × 12 = $48.

Therefore, $48 is the price of 12 hats.

Answer:

Step-by-step explanation:

The perimeter is twice the sum of length and width. Then the sum of length and width is 90 yards. Their product is the area, so we have ...

  x(90 -x) = 2000 . . . . where x is length or width

  x^2 -90x +2000 = 0 . . . . rearrange to standard form

  (x -40)(x -50) = 0 . . . . . . . factor

  x = 40  or  x = 50

The dimensions of the rectangular plot are 40 yards by 50 yards.

Answer:

  x = 90 degrees

Step-by-step explanation:

There are several ways to go about this (as is often the case with math problems). Here, we'll use the fact that an inscribed angle is half the measure of the arc it intercepts.

  arc DE = 2×∠DFE = 60°

  arc EF = 2×∠ECF = 60°

  arc CF = 2×∠CEF = 60°

Then arc DEC is ...

  arc DEC = arc DE +arc EF +arc FC = 60° +60° +60° = 180°

Angle DBC is half the measure of this arc, so is ...

  ∠DBC = 180°/2 = 90° = x

Answer:

13 lbs

Step-by-step explanation:

to find 1/10 we divide by 10

This can be found by moving the decimal back by one

So 130/10=13

13 lbs were lost

The person lost 13 lbs of weight.

Weight is the measure of how heavy an object is. Weight is measured in standard customary units. The mass of an object is the amount of material it contains.

Given that, the person weight=130 lbs and he lost 1/10 of his weight.

We need to find how much weight was lost.

Now, weight lost [tex]=\frac{1}{10} \times 130=13[/tex] lbs.

Hence, the person lost 13 lbs of weight.
