Answer:
Step-by-step explanation: one has to be 90 degrees, so 34 plus 90. The angles of a triangle always add up to 180 so, subtract the answer of 34 plus 90 from 80 and you should get the answer.
Armando deposits $3,827 into a bank account paying 2.8% interest,
compounded monthly (12 times per year). How much money will he have in
his bank account after 16 years? PLEASE HELP!!
Answer:
$745,460.8
Step-by-step explanation:
2.8/100 × 3827 = $107.16
monthly = 1/12
[tex]p = \frac{100 \times i}{rt} = \frac{100 \times 107.16}{2.8 \times \frac{1}{12} } = \frac{10716}{0.23} \\ = 46591.3[/tex]
$46,591.3 in 1year
16 years; $46,591.3 × 16 = $745,460.8

A teacher initially plans to take an SRS of size 50 from his large high school and calculate the sample mean x bar of student GPAs. Later, the teacher decides to increase the sample size so that the standard deviation of the sampling distribution of x bar will be half as big as when using a sample size of 50. What sample size should the teacher use?
57
100
150
200
354
Answer:
should be 200 because I think you quadrupole it and 50 x 4 =200
Step-by-step explanation:
Answer:
The answer is 200. 50 * 4 = 200.

Given right triangle ABCABC with altitude \overline{BD} BD drawn to hypotenuse ACAC. If BC=10BC=10 and DC=5,DC=5, what is the length of \overline{AC}? AC ?
Answer: [tex]\overline{AC}=[/tex] 12.5
Step-by-step explanation: The triangle ABC and its altitude [tex]\overline{BD}[/tex] is represented in the figure below.
Altitude is a segment of line that link a vertex and the opposite side, forming a right angle.
So, because of [tex]\overline{BD}[/tex], now we have two similar triangles, which means that ratios of corresponding sides are equal:
[tex]\frac{\overline{BD}}{\overline{BC}} =\frac{\overline{AD}}{\overline{BD}}[/tex]
[tex]\overline{BD}^{2}=\overline{BC}.\overline{AD}[/tex] (1)
This is always true for a right triangle and a altitude drawn to the hypotenuse.
Triangle BDC is also right triangle. So, we can use Pythagorean theorem to determine the missing side.
[tex]\overline{BC}^{2}=\overline{CD}^{2}+\overline{BD}^{2}[/tex]
[tex]\overline{BD}^{2}=\overline{BC}^{2}-\overline{CD}^{2}[/tex] (2)
Substituting (2) into (1):
[tex]\overline{BC}^{2}-\overline{CD}^{2}=\overline{BC}.\overline{AD}[/tex]
We want to find f, so:
[tex]\overline{AD}=\frac{\overline{BC}^{2}-\overline{CD}^{2}}{\overline{BC}}[/tex]
[tex]f=\frac{10^{2}-5^{2}}{10}[/tex]
f = 7.5
The length of [tex]\overline{AC}[/tex] is
[tex]\overline{AC}=f+5[/tex]
[tex]\overline{AC}=7.5+5[/tex]
[tex]\overline{AC}=12.5[/tex]
The length of the hypotenuse of triangle ABC is 12.5 units.

Ruby had 30 dollars to spend on 3 gifts. She spent 9 7 10 dollars on gift A and 5 2 5 dollars on gift B. How much money did she have left for gift C?
Answer:
$14 9/10
Step-by-step explanation:
Ruby had 30 dollars to spend on 3 gifts. She spent 9 7 10 dollars on gift A and 5 2 5 dollars on gift B. How much money did she have left for gift C?
From the above question,
$30 = Gift A + Gift B + Gift C
She spent 9 7/ 10 dollars on gift A and 5 2/5 dollars on gift B.
$30 = $9 7/10 + $5 2/5 + Gift C
Gift C = $30 - ( $9 7/10 + $5 2/5)
Lowest Common Denominator = 10
Gift C = $30 - $14+(7 + 4/10)
Gift C = $30 - $14+(7 + 4/10)
Gift C = $30 - $14+(11/10)
$30 - $14+(1 1/10)
$30 - $15 1/10
Gift C = $14 9/10
Therefore, the amount of money she had left for gift C is $14 9/10
Which of the following statement(s) describes the rate of change of f over the interval 1.5≤x≤3? Select all that apply.
Answer:
error
Step-by-step explanation:
Answer: The rate of change = 2
✔️The rate of change is increasing because the value is a positive value.
✔️The rate of change is also constant over 1.5 ≤ x ≤ 3 since the line is straight.

Two coins are tossed and a number cube (dice) is rolled. How many outcomes are
possible?
A. 24
B. 18
C. 12
D. 10
Answer:
C
Step-by-step explanation:
I tried my best, The coin has 2 outcomes and the dice has 6 so 6 times 2 is 12
Divide. 0.996 ÷ 0.12
Answer:
8.3
Step-by-step explanation:
Answer:
- 0.996 - Percentage increase =
- 0.996 - (12% × - 0.996) =
- 0.996 - 12% × - 0.996 =
(1 - 12%) × - 0.996 =
(100% - 12%) × - 0.996 =
88% × - 0.996 =
88 ÷ 100 × - 0.996 =
88 × - 0.996 ÷ 100 =
- 87.648 ÷ 100 =
- 0.87648 ≈
- 0.88

The cost of metal is proportional to the weight of the metal. Martin buys 12 pounds of metal for $33.00. Create an equation that can be used to determine the cost, in dollars, c, for m pounds of metal.
Step-by-step explanation:
First we need to find the unit price33 / 12: 2.75$ per pound
2.75m = c
We can test if this equation works2.75(12) = c
33 = c
Which is correct

Solve the system of equations by the substitution method.
X + 8y = 21
3x + 5y = 6
Step-by-step explanation:
the first one if you are solving for x it will be x=21-8y
if you are solving for y it will be y =21/8 - x/8
the second one will be if you are solving for x x = 2 -5y/3
solving for y is y=6/5-3x/5
If you deposit $6000 into an account paying 8% annual interest compounded monthly, how much money will be in the account after 7 years?
Answer:
$10278
Step-by-step explanation:
Given data
P= $6000
R= 8%
T= 7 years
The compound interest formula is
A=P(1+r)^t
substitute
A=6000(1+0.08)^7
A=6000(1.08)^7
A=6000*1.713
A=$10278
Find the value of each variable.
Answer:
x = 4
Step-by-step explanation:
the given figure is of an isoceles triangle.
The two angles opposite are congruent(i.e78 degrees) .
That is the sides opposite to them are also congruent.
I. e 4x + 23 = 10x - 1
I. e 4x - 10x = -1 -23
I. e -6x = -24
I. e -x. = -24/6
Dividing by 6 to 24 we get,
-x = -4
therefore by removing the minus sign from both the sides,
the answer comes x = 4

Find the slope of the line on the graph.
Write your answer as a fraction or a whole
number, not a mixed number or decimal.
Answer:2/6 i might be wrong but whats the answer choices?
Step-by-step explanation:
Answer:
Step-by-step explanation:
You can see that (0,4) and (1,1) are points on the line. Use their coordinates to determine the slope of the line.
slope = (difference of y-coordinates)/(difference of x-coordinates)
= (1-4)/(1-0)
= -3
Write
