Answers

Answer:

1+2x=y

Step-by-step explanation:

X: Number of sticks

Y= number of cakes

There is already one cake, so you must add one to the equation. You multiply x by two since 1 stick of butter (x) makes two cakes.

[tex]Opposite =- \frac{4}{5}[/tex]

Step-by-step explanation:

Given

[tex]Number = \frac{4}{5}[/tex]

Required

Determine its opposite

To get the opposite of a number, we simply subtract it from 0.

So, we have:

[tex]Opposite =0 - \frac{4}{5}[/tex]

[tex]Opposite =- \frac{4}{5}[/tex]

Hence, the opposite is -4/5

Step-by-step explanation:

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

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

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

the three angles of a triangle are in the ratio 1:3:5 find the angles​

Answers

Answer:

The ratio 1:3:5 by doubling each number is the same as 2:6:10 and the big one 10 is 10/(2+6+10) = 10/18 of the total, so multiplying top and bottom by 10 gives 100/180, so the biggest angle is 100° since the sum of all angles must be 180°.

Way to do

a. 17 out of 85 how many percentage?

17/85 × 100 = 20%

b. what is 17% of 90?

? /90 × 100 = 17? /90 = 17 : 100? /90 = 0.17? = 90 × 0.17 ? = 15.3

c. 1026 out of ? = 54%

1026/? × 100 = 541026/? = 0.54? = 1026 : 0.54? = 1900

d. 8.1% of 90 = ?

90 × 8.1/100 = 7.29

e. ?% of 50 = 90

50 × ?/100 = 90?/100 = 90:50?/100 = 9/5? = 9/5 × 100? = 180

f. 88% of ? = 154

? × 88/100 = 154? = 154 : 88/100? = 175
