Each table in a library can seat up to 5 people. There are enough tables for 75 people. How many tables are there in the library?

Answers

Answer:

15 tables

Step-by-step explanation:

75/5 = 15

Answer:

There are 15 tables in the library.

Step-by-step explanation:

You know this because you know the library holds 75 people and you know how many people can sit at a table so to find the answer you divide 75 by 5 and you get 15. To check this you can multiply 15 by 5 and you will get 75.

write an equation represented by the graph shown !

Answers

Answer:

y = |x+1.5|

Step-by-step explanation:

Start with the graph of y = |x|. To shift it left by 1.5 units, replace x with x+1.5.

General rules for shifting graphs:

Shift y = f(x) up by a units: y = f(x) + aShift y = f(x) down by a units: y = f(x) - aShift y = f(x) left by a units: y = f(x + a)Shift y = f(x) right by a units: y = f(x - a)

Answer:

y=abs(x+1.5)

THE FASTEST AND MOST ACCURATE GETS THE BRAINLIEST NO LINKS PLS. Hannah and Harold are making cookies for a bake sale, and they need to make a lot of them. They need to make 70 baggies of cookies that each have 4 cookies in them. The recipe they are using says that one batch will make 2 dozen cookies.

Answers

Answer:

They need to make at least 12 batches.

Step-by-step explanation:

First, we need to find how many cookies in total, so we multiply 70 by 4.

70*4 = 280.

Secondly, 1 batch makes 2 dozen cookies, or technically 24 cookies. So we need to find how many batched with 280 divided by 24. This results in 11.6 repeating. But if you round it up, you get 12.

Time to check:

12 * 24 = 288. So it's the amount of cookies needed with 8 remaining.

Hope this helps.

Lily had 95 inches of yarn. After cutting 4 pieces that were each the same length, she had 15 inches of yarn left.
How long was each of the 4 peices of yarn that Lily cut?

Answers

Each was 10 inches because she had 95 and 95-15=40 divided by 4 = 10

Answer:

20 inches

Step-by-step explanation:

Step 1: Subtract the total from what was left

[tex]95 - 15 = 80[/tex]

Step 2: Divide the result into the 4 pieces

[tex]80 \div 4[/tex]

[tex]=\frac{80}{4}[/tex]

[tex]= 20[/tex]

What is wrong with this solution? -6t + 16 = -8 Step One: -6t + 16 = -8 - 16 Step Two: -6 • -6t = -24 • -6 Solution: t = 144

Answers

Answer:

t = 4

Step-by-step explanation:

In step two, instead of multiplying by -6 on both sides, you need to divide by -6 to isolate t.

-6t = -24

÷-6 ÷-6

t = 4

When you multiply by -6 on both sides, the equation would be 36t = 144, which is not what we want. The opposite of multiplication is division, and in order to get the answer, you divide by the number multiplied.

Four equivalent forms of a quadratic function are given. Which form displays the zeros of function h?

Answers

Answer:

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

Step-by-step explanation:

Given

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

[tex]h(x) = -2(2x^2 - 8)[/tex]

[tex]h(x) = -4(x^2 - 4)[/tex]

[tex]h(x) = -4x^2 + 16[/tex]

Required

Which shows the zeros of h(x)

To determine the zeros of a function, the function must be written as:

[tex]h(x) = n(x \± a)(x \± b)[/tex]

Where

[tex]n \ne 0[/tex]

[tex]\± a,\± b[/tex] are the zeros

Of options (a) to (d), only (a) is written in the form:

[tex]h(x) = n(x \± a)(x \± b)[/tex]

i.e.

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

Other options do not show the zeros

Again, this is a first-time event, a breakthrough, and that's why I believe this treaty will not only lessen the threat of war, it can also speed along a process that may someday remove that threat entirely.Indeed, this treaty, and all that we've achieved during this summit, signals a broader understanding between the United States and the Soviet Union. B) It is an understanding that will help keep the peace as we work toward the ultimate goal of our foreign policy: a world where the people of every land can decide for themselves their form of government and way of life.Yet as important as the INF treaty is, there is a further and even more crucial point about the last 3 days and the entire summit process: Soviet-American relations are no longer focused only on arms control issues. They now cover a far broader agenda, one that has, at its root, realism and candor. C) Let me explain this with a saying I've often repeated: Nations do not distrust each other because they're armed; they are armed because they distrust each other. And just as real peace means the presence of freedom and justice as well as the absence of war, so, too, summits must be discussions not just about arms but about the fundamental differences that cause nations to be armed.Dealing then with the deeper sources of conflict between nations and systems of government is a practical and moral imperative. D) And that's why it was vital to establish a broader summit agenda, one that dealt not only with arms reductions but also people-to-people contacts between our nations and, most important, the issues of human rights and regional conflicts.

If you have 20 balls, and 1 is blue, you can say that 5% (or 5 out of 100 balls) is blue. Similarly, if a solution is 5% KI by mass, you can say that 5 g per 100 g solution is KI. When mass percent is used as a conversion factor, it can be expressed in the units required to solve the problem provided that the ratio remains constant. If the numerator is divided by 100, the denominator must also be divided by 100.
