What does estimate mean?

1 answer:

8 0

Estimate means to give a guess kinda. When you estimate lets say someone has 4 cookies and they also have $20 and the cookies are $6 a dozen. Take 20 divide it by 6 which would be 3.3333. That person can buy 3.3333 dozens. If you estimate that person can buy a total of 3 dozen. Hope this helped ;)

Two angles form a linear pair the Measure of one angle is 2.6 times the measure of the other angle find the measure of each angl

Sedaia [141]

Answer:

The measures of the angles are 50° and 130°

Step-by-step explanation:

Let

x ----> the measure of one angle

y ----> the measure of the other angle

we know that

If two angles form a linear pair , then their sum is equal to 180 degrees

$x+y=180$ -----> equation A

$x=2.6y$ ----> equation B

substitute equation B in equation A

$2.6y+y=180$

solve for y

$3.6y=180$

$y=50^o$

Find the value of x

$x=2.6(50)=130^o$

The measures of the angles are 50° and 130°

Help me?<br> 185/100 + 50% + 4%=?

Taya2010 [7]

Answer:

2.39

Step-by-step explanation:

Convert everything to a decimal.

To do that with a fraction divide the numerator by the denominator.

185 divided by 100 = 1.85

185/100 = 1.85

To convert a percent to a decimal divide the number by 100.

50 divided by 100 = 0.5

50/100 = 0.5

4 divided by 100 = 0.04

4/100 = 0.04

Now add:

1.85 + 0.5 + 0.04 = 2.39

I'm stuck on this one! Help please?

zepelin [54]

Expand

(4a + 12 = 12 + 4a)

Cancel 4a on both sides

12 = 12

Since both sides are equal there are infinitely many solutions

Process of elimination, cross out d) no solution. But I would best go with C)

If 25% of the students in elementary algebra courses receive a grade of A, and there are 300 students enrolled in elementary alg

djyliett [7]

Answer:

Total number of students receiving A grade = 75

Step-by-step explanation:

Total number of students enrolled in elementary algebra this year =300

Percentage of students receiving a grade of A = 25%

To find number of students that will receive a grade of A.

Solution:

In order to find the number of students that will receive a grade of A, we will find the percentage students receiving A grade of the total number of the student.

Number of students receiving A grade = $25\%\ of\textrm{ Total number of students}$

⇒ $25\%\ of\ 300$

Writing 25% as fraction and multiplying.

⇒ $\frac{25}{100}\times 300$

⇒ $\frac{7500}{100}$

⇒ $75$

∴ Total number of students receiving A grade = 75 (Answer)
