How many desserts are at the bake sale in all?

Answers

Answer:

300

Step-by-step explanation:

120÷40=3

3×100=300

dividing 120 by 4 will get you 1% so then to find 100% you multiple by 100

Answer:

300

Step-by-step explanation:

The total number of desserts is x. we don't know what it is.

40% of all the desserts are cookies.

That is 40% of x.

We are told that 120 of the desserts are cookies.

That means that 40% of all desserts amount to 120.

40% of x = 120

0.4x = 120

Divide both sides by 0.4

0.4x/0.4 = 120/0.4

x = 300

Answer: In all there are 300 desserts.

What percent of 180 is 45?
4.5
18
22
25

Answers

Answer:

it is 25 hope this helped

Step-by-step explanation:

Hi there! :)

Answer:

The answer is D. 25% of 180 is 45.

Step-by-step explanation:

Let's replace "what percent" with the letter "x" because it's what we are looking for.

The word "of" is the same thing as a multiplication sign, which means that the sentence "What percent of 180 is 45?" can turn into "x times 180 is 45".

The word "is" is the same thing as an equation sign, wich means that you can write this as an equation:

x × 180 = 45

180x = 45

Now all you have to do is solve this equation by isolating "x" to find your answer:

180x = 45

Divide each side of the equation by 180 → 45 ÷ 180 = 0.25

x = 0.25

0.25 = 25 ÷ 100 = 25%

There you go! I really hope this helped, if there's anything just let me know! :D

こんにちは！ :)

回答：

答えはDです。180の25％は45です。

ステップバイステップの説明：

「何パーセント」を文字「x」に置き換えましょう。これが私たちが探しているものだからです。

「of」という単語は乗算記号と同じです。つまり、「180の何パーセントが45ですか？」という文です。 「x×180は45」になります。

「is」という単語は方程式の記号と同じものです。これは、これを方程式として記述できることを意味します。

x×180 = 45

180x = 45

今、あなたがしなければならないのはあなたの答えを見つけるために「x」を分離することによってこの方程式を解くことです：

180x = 45

方程式の各辺を180→45÷180 = 0.25で割ります

x = 0.25

0.25 = 25÷100 = 25％

What is the coordinates

Answers

Answer:

on a graph here is the answer

Step-by-step explanation:

Answer:

(0, 3 )

Step-by-step explanation:

Given the 2 equations

- x - 6y = - 18 → (1)

- 8x + y = 3 → (2)

Multiplying (2) by 6 and adding to (1) will eliminate the y- term

- 48x + 6y = 18 → (3)

Add (1) and (3) term by term to eliminate y , that is

- 49x + 0 = 0

- 49x = 0 , thus

x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (2)

- 8(0) + y = 3

y = 3

solution is (0, 3 )

F (3,5)
H (4,9)
G (9, 17)
J (6, 11)​

Answers

Answer:

H

Step-by-step explanation:

Answer: H

Explanation:

The format is (x,y) ; (4,9) Therefore, you plug in 4 for x then 9 for y. Which will give you “9=2(4)-1” and then simplify, which will give you.. “9=8-1 AKA 9=7” which is not accurate. Therefore that is NOT a solution to the equation...

STEP-BY-STEP:

y = 2x - 1

9 = 2(4) - 1

9 = 8 - 1

9 = 7

^^^^ NOT TRUE

So, therefore the answer IS H (4,9) because it’s asking what is NOT a solution.

What is the measure of ∠ACV shown in purple?

Answers

Using the angle addition postulate, the measure of angle ACV shown in purple is given by:

<ACV = 224º.

What is the angle addition postulate?

The segment addition postulate is a geometry axiom that states that an angle, divided into a number of smaller angles, has the measure given by the sum of the measures of the smaller angles.

For this problem, angle ACV is divided into:

Angle ACD.Angle DCV.

Hence:

<ACV = <ACD + <DCV.

The measures are given as follows:

<ACD = 136º.<DCV = 88º.

Hence the measure is given as follows:

<ACV = <ACD + <DCV = 136º + 88º = 224º.
