The number of applicants to a university last year was 11,450. This year, the number of applicants grew by 2%. How many applicants are there this year?
11,679
13,740
20,610
23,900
Answer:
11679
Step-by-step explanation:
Increased by 229
First you need to find the 2%
So to find the 2%
2/100 * 11450=229
Now add 11450+229= 11679
Answer:
11,679
Step-by-step explanation:
Start off making the 2% into a decimal so you can multiply it with the full amount of applications for the year before. 2% in decimal is .02 because you move the decimal twice to the left. Now that you have .02, multiply it by 11,450. (11,450)*(.02) which should be 279. Now you have to add the 279 to the 11,450 because they were admitted as well. (11,450+279)= 11,679

Apply the distributive property to factor out the greatest common factor.
250-150x =
Answer:
[tex]50(5 - 3x)[/tex]
Step-by-step explanation:
The given expresion is
[tex]250 - 150x[/tex]
The greatest common factor is 50.
We rewrite using the distributive property to get;
[tex]50 \times 5- 50 \times 3x[/tex]We collect the highest common factor to obtain:
[tex]50(5 - 3x)[/tex]
Therefore when we factor out the greatest common factor from the given expresion we get;
[tex]50(5 - 3x)[/tex]
To apply the distributive property and factor out the greatest common factor from the expression 250-150x, we need to find the largest number that evenly divides into both numbers. In this case, the greatest common factor is 50, so the expression can be rewritten as 50(5 - 3x).
Explanation:To factor out the greatest common factor from the expression 250-150x, we need to find the largest number that evenly divides into both 250 and 150. In this case, the greatest common factor is 50. We can rewrite the expression as 50(5 - 3x).

Choose the constant that could be multiplied by each equation to create a system of equivalent equations with opposite terms.
2x + 3y = 1
5x + 2y = 8
The first equation can be multiplied by 5 and the second equation by 2.
The first equation can be multiplied by –5 and the second equation by –2.
The first equation can be multiplied by –5 and the second equation by 2.
Answer:
I think it's the third one. Because it will make both equation's x a opposite value (one is positive and one is negative).
Step-by-step explanation:
Because 2x+3y=1*5= 10x+15y=5 and then 5x+2y=8*-2 = -10x+4y=-16 both equations will cancel the Xs out and then you can solve for Y.

6/4 as a whole number or a mixed nimber
Answer: 1 2/6 which needs to be simplify which is 1 1/3.
We can see here that 6/4 as a mixed number is = 1 (1/2).
What is mixed number?A mixed number is a representation of a number that includes both a whole number and a fraction. It consists of an integer part and a fractional part. The integer part represents a whole number, while the fractional part represents a proper fraction.
To express 6/4 as a mixed number, you divide the numerator (6) by the denominator (4) and express the remainder as a fraction with the same denominator. In this case, 6 divided by 4 is 1 with a remainder of 2. So, 6/4 can be written as the mixed number 1 (2/4), which can be simplified to 1 (1/2).

Jose is driving to Denver. Suppose that the remaining distance to drive (in miles) is a linear function of his driving time (in
minutes). When graphed, the function gives a line with a slope of -0.95. See the figure below.
Jose has 48 miles remaining after 50 minutes of driving. How many miles were remaining after 34 minutes of driving?
Answer:
63.2 miles
Step-by-step explanation:
The given slope and point can let us use the point-slope form of the equation for a line:
y = m(x -x1) +y1
y = -0.95(x -50) +48
We want to find the value of y for x=34.
y = -0.95(34 -50) +48 = 63.2
Jose had 63.2 miles remaining after driving 34 minutes.

Answer: 8 7/9 + 4 1/8 = 929 /72 = 12 65/72 ≅ 12.9027778
Step-by-step explanation:
Conversion a mixed number 8 7

to a improper fraction: 8 7/9 = 8 7
9
= 8 · 9 + 7
9
= 72 + 7
9
= 79

To find new numerator:
a) Multiply the whole number 8 by the denominator 9. Whole number 8 equally 8 * 9
9
= 72
9
b) Add the answer from previous step 72 to the numerator 7. New numerator is 72 + 7 = 79
c) Write previous answer (new numerator 79) over the denominator 9.
Eight and seven ninths is seventy-nine ninths
Conversion a mixed number 4 1

= 32 + 1
8
= 33
8
To find new numerator:
a) Multiply the whole number 4 by the denominator 8. Whole number 4 equally 4 * 8
8
= 32
8
b) Add the answer from previous step 32 to the numerator 1. New numerator is 32 + 1 = 33
c) Write previous answer (new numerator 33) over the denominator 8.
Four and one eighth is thirty-three eighths
Add: 79

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(9, 8) = 72. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 8 = 72. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - seventy-nine ninths plus thirty-three eighths = nine hundred twenty-nine seventy-seconds.
