3+(55-111)/25 equals what

Answers

Answer:

0.76

Step-by-step explanation:

3+(55-111)/25

=3+(-56)/25

=3+ (-2.24)

=0.76

Answer:

3+(55-111)/25= 0.76

Step-by-step explanation:

Using PEMDAS, you solve 55-111 which is -56

Then you divide -56 by 25 because it is the fourth step, you get -2.24

Add three to -2.24 to get 0.76

If you round UP to the nearest tenth, it will be 0.80

If you round DOWN to the nearest tenth, it will be 0.70

Last year, Greg got a new job managing the gift shop at the Bern Valley Zoo. One of his responsibilities was to track the shop's total sales each day. This box plot shows the results. Gift shop sales ($) 200 250 300 350 400 450 What percent of the time did the gift shop have sales of $350 or less? %

Answers

Answer:

Step-by-step explanation:

There were 4 days when sales were 350 or less out of 6 days so

100(4/6)=400/6=[tex]66\frac{2}{3}\% $ or rounded to 66.67% $ [/tex]

The percentage of the time did the gift shop have sales of $350 or less should be considered as the 66.67%.

Calculation of the percentage:

Sinceas we can see that there are total 6 things out of which 4 should be within 350 or less than 350

So here the percentage be like

[tex]= 4\div 6[/tex]

= 66.67%

Hence, The percentage of the time did the gift shop have sales of $350 or less should be considered as the 66.67%.

18% of the the students at a school are in year 8 and 16% of the students are in year 9. If the school has 126 tera 8 students, determine the number of year 9 students.

Answers

Answer:

112

Step-by-step explanation:

The general form of all percentage questions is: the chunk= (some percentage) (of the whole), or c=p*w

We know that 18% of students are 8th grade and that is 126 students, so p = 0.18 and c=126 (126 students are 18% of the whole school)

126 = (0.18)w, divide both sides by 0.18

126/(0.18) = w = 700

9th graders are 16% of the school or 16% of 700 students

c = (0.16) 700 = 112 students

All I want to know is the formula and I will do the rest...pls someone help me with the formula...

Answers

Hey in this type of questions there's no formula, you need to use your logic.

#Note that the full degree or a triangle is 180°

#The L in triangle is 90°

I see that you want to try to do it by yourself, i will give you the tips. to get the <BAD

#since <DAC is 90°, The ADB is 90° (180°-90°)

<BAD = 180° - 90° - 25° = 65°

Now, try to find <BCA yourself.

Tell me if you give up, i will tell you lol.

The angles of a triangle add up to 180 degrees.

The second angle is 20 degrees larger than the smallest angle.

The third angle is 3 times as big as the smallest angle.

Find the measure of the smallest angle (in degrees)

Answers

Answer: 32 degrees

Step-by-step explanation:

small angle : x

middle angle: x + 20

large angle: 3x

Form an equation: 5x + 20 = 180

5x = 180 - 20

5x = 160

x = 160/5

x = 32

Answers

Answer:

$9.86

Step-by-step explanation:

Frist you read the problem and you see that she pays $1.89 for one drink

so you write down $1.89

then 3 cookies for $0.99 so you multiply $0.99 by 3 and you get $2.97

so you write down $2.97

next 2 slices of pizza for $2.50 so you multiply 2 by $2.50 and you get $5.00

so you write that down

lastly you and the answers you wrote down and you get $9.86

Answer:

2 dollars for kids

5 dollars for adults

Step-by-step explanation:

We will let x= children

y= adult

we know that

33x+42y=276

46x+40y=292

There are a lot of ways you can solve this but I think it's easiest if we use (what I think is called elimination)

we will start by mulitiplying the second equation by 1.05 to get

48.3x+42y= 306.6

We will subtract the first equation from the second to get

15.3x= 30.6

Solve for x and get 2

Now that we know what x equals we can plug that into any equation and solve for y

we have

33(2)+42y=276

y=5
