A total of $8000 is invested: part at 5% and the remainder at 13%. How much is invested at each rate if the annual interest is $730?
Answer:
$3875 at 5%
$4125 at 13%
Step-by-step explanation:
Let x = amount invested at 5%.
Let y = amount invested at 13%.
x + y = 8000
0.05x + 0.13y = 730
Solve the first equation for x and sustitute into the second one to solve by the substitution method.
x = 8000 - y
0.05(8000 - y) + 0.13y = 730
400 - 0.05y + 0.13y = 730
0.08y = 330
y = 4125
x = 8000 - 4125
x = 3875
Answer:
$3875 at 5%
$4125 at 13%

Using weighed average, it is found that the student will need a GPA of 3.31.
To find a weighed average, each value is multiplied by it's weight.
For the student's average, we have that:
GPA of 3.15 with a weight of 32.GPA of x with a weight of 14.We want the mean to be 3.2, thus:
[tex]\frac{3.15(32) + 14x}{32 + 14} = 3.2[/tex]
[tex]3.15(32) + 14x = 46(3.2)[/tex]
[tex]14x = 46(3.2) - 32(3.15)[/tex]
[tex]14x = 46.4[/tex]
[tex]x = \frac{46.4}{14}[/tex]
[tex]x = 3.31[/tex]
The student will need a GPA of 3.31.

Find the slope from the 2 points.
(-12,-9) and ( 18, 6)
-2
-1/2
2
1/2
Step-by-step explanation:
the slope of a line is the ratio y/x.
that means when going from one point to the other, how many units is y changing, when x changes a certain number of units.
so, going from one point to the other here, x changes by 30 units (from -12 to +18). and y changes 15 units (from -9 to 6).
therefore, the slope is
15/30 = 1/2

PLEASE MARK AS BRAINLIEST!!!!!Example # 12: The probability that Mary can work a problem is 70%.
Find the probability that Mary cannot work the problem.
HELP PLEASE!!!
Answer:
the answer is 30% hope this helps you
Answer:
30%
Step-by-step explanation:
The two outcomes (can work the problem and can't work the problem) are complementary.
In probability theory, the complement of any event A is the event [not A], i.e. the event that A does not occur. The event A and its complement [not A] are mutually exclusive and exhaustive.
Complementary events are two outcomes of an event that are the only two possible outcomes.
Complementary outcomes add to 1 or 100%.
100 - 70 = 30.
A volunteer at the zoo is responsible for feeding the animals in 15 exhibits in the reptile house. This represents 20% of the total exhibits in the reptile house. How many exhibits are in the reptile house.
The 75 exhibits are in the reptile house.
we have given that,
A volunteer at the zoo is responsible for feeding the animals in 15 exhibits in the reptile house.
We have to determine how many exhibits are in the reptile house.
Therefore we have
if 15 exhibits = 20% of total exhibits,
What is the percentage?
A percentage is a number or ratio expressed as a fraction of 100.
then 15/20% = 75 total exhibits in the reptile house
We can check the answer,
75 x 20% = 15
Therefore the 75 exhibits are in the reptile house.
