Answer:Integer Numbers?

Step-by-step explanation:

Answer:

The savings were changed by $88

Step-by-step explanation:

1 backpack costs 8 dollars and they bought 8 of them, you have to multiply 8 dollars by 8 cause there is 8 backpacks which is 64 , pen and pencils for 1 backpack costs 3 dollars , so you have to multiply 3 by 8  cause there are 8 backpacks which is 24. then you add 64 and 24 which is 88

Answer:

The answer is 410 5/8

Answer:

a) -99

b) -12

c) -105

d) -46

Answer:

a) | -81 - 17 | = 98

b) | 8 - 20 | = 12

c) | -76 - 25 | = 101

d) | -91 + 45 | = 46

Remember, absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative.

The three possible sets of integers whose product is -7 are:

1. (1, 1, -7) (least to greatest)

2. (-1, 1, 7) (least to greatest)

3. (-1, -1, 7) (least to greatest)

To find the three possible sets of integers whose product is -7, we need to consider all the combinations of three integers whose product results in -7. Keep in mind that each set should use unique integers. Let's explore the options:

1. Set 1: [tex]\(1 \times 1 \times -7 = -7\)[/tex]

2. Set 2: [tex]\((-1) \times 1 \times 7 = -7\)[/tex]

3. Set 3: [tex]\((-1) \times (-1) \times 7 = -7\)[/tex]

The three possible sets of integers whose product is -7 are:

1. (1, 1, -7) (least to greatest)

2. (-1, 1, 7) (least to greatest)

3. (-1, -1, 7) (least to greatest)

Each set consists of unique integers, and the product of all three integers in each set is -7.

Answer:

your answer would be 7285.63

Having two periods means it has two groups of digits separated by a comma.

6 digits would be xxx,xxx

An 8 worth 80 means the 8 is in the tens place.

And you have a 2 in the hundreds place.

All other digits can be any number.

Hi :)

Rate of change is the change in the y divided by the change in x

Here's the formula

R = (∆y / ∆x )

R = rate of change

∆y = change in y

∆x = change in x

Irrational

Step-by-step explanation:

Because irrational numbers are defined as a subset of real numbers, all irrational numbers must be real numbers.

Answer: x+5/8 = 1 is the equation where x is the remaining coffee.

Step-by-step explanation:

he drank = 5/8

whole coffee = 1

so

let coffee remaining be x

1-5/8 = x

x+5/8 = 1

The required equation, for the remaining cup of coffee, is x = 1+(- 5/8).

To determine the addition equation of coffee remaining in the cup, for the condition Kelly bought a cup of coffee and drank 5/8 it.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the coffee remaining in the cup be x,
Now, according to the question,
1 = x + 5/8
x = 1 - 5/8
For the addition equation,
x = 1 +(-5/8)

Thus, the required equation, for the remaining cup of coffee, is x = 1+(- 5/8).

Answer: Thrid choice. 4

Step-by-step explanation:

Given equation

(-3/4)m - (1/2) = 2 + (1/4)m

The least common multiple of the denominator

First three multiples of 2: 2, 4, 6

First three multiples of 4: 4, 8, 12

Since 4 is the first common multiple, 4 is the least common multiple of 2 and 4.

By multiplying [tex]\boxed{4}[/tex] on both sides, the fraction can be eliminated.

Answer:

81

Step-by-step explanation:

it can be expressed as a product of two smaller numbers 9×9

Step-by-step explanation:

a) is really easy, right ?

the surface area consists of 6 rectangles (as you know, every die has 6 sides). they are 3 pairs of equally sized rectangles.

there are 2 rectangles 7×1, 2 rectangles 7×2, and 2 rectangles 2×1

SA = 2×7×1 + 2×7×2 + 2×2×1 = 14 + 28 + 4 = 46 in²

the volume is just length×width×height

V = 7×2×1 = 14 in³

b)

a little bit more difficult, but with a little trick just as easy.

the surface area consists of the 2 circle areas and the mantle "coating".

the area of a circle is pi×r².

we have to be careful as the given 10 ft is the diameter of these circles. the radius is half of it : 5 ft.

the area of the "mantle" we can calculate by imagining we simply slice it open with one straight line from top to bottom. and then we cut it off the two circles and put it flat on the table.

now we see it is just a rectangle. one side is 12ft. the other is the circumference of the previously attached circles.

circumference of a circle is 2×pi×r

so the surface area is 2×circle + (circumference circle)×12

SA = 2×pi×5² + (2×pi×5)×12 = 50pi + 120pi = 170pi =

≈ 534.07 ft²

the volume is one base area (circle) times height

V = pi×5²×12 = 300pi ≈ 942.48 ft³

Answer:

No, they are not.

Step-by-step explanation:

A ratio can be written as a fraction. So 3:5 is the same as 3/5 and 2:4 is the same as 2/4.

3/5 = 2/4

0.6 = 0.5 INCORRECT

As you can see, the both don't equal the same numbers, so they aren't equivalent.

they're the same triangle, but one is bigger. the 2,5 and 5 sides are equivalent, so with that we are able to know the big triangle is exactly 2x bigger. u multiply the 2 side (because it's equivalent to the x side) by 2 (bc the triangle is 2 times bigger) and you get 4 = x

Answer:

7

Step-by-step explanation:

3/5(t+18)  = -3(2-t)                   Distribute

3/5t + 10 4/5 = -6 + 3t            Subtract 3/5t in both sides

10 4/5 = -6 + 2 2/5t                Add 6 on both sides

16 4/5 = 2 2/5t                       Divide

t = 7
