Answer:
68
Step-by-step explanation:
the interior angles of a triangle always adds up to 180. So if you add 59 and
53 together you would get 112. Then subtract that from 180 and you would get 68.

For the the axis of symmetrythe vertex and the yintercept y = x ^ 2 + 16x + 24
Answers
Answer: D (bottom option)
Axis of Symmetry: x = -8
Vertex: (-8, -40)
Y-Intercept: 24
Step-by-step explanation:
Start by putting the equation into vertex form, which you can do by completing the square. This means the equation will in the form [tex]y=a(x-h)^2+k[/tex].
Once you've done that, you'll get [tex]y=(x+8)^2-40[/tex]. This means that h = -8 and k = -40, so the vertex is (-8, -40) because vertex form is (h, k).
The axis of symmetry is x = -8, because the axis of symmetry is x = h.
The Axis of Symmetry is -8
9. Use the compound-interest formula to find the account balance A, where P is principal, r is interest rate, n is number of compounding periods per year, t is time, in years, and A is account balance.
Answers
Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. The account balance after a period of 5 years will be $1.63634×10²⁰.
What is compound interest?Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Given the principal amount is $12,385, the rate of interest is 7.5%, and the time period is daily. Therefore, the amount can be written as,
[tex]A = P(1 + \frac{r}{n})^{nt}\\\\A = \$12,385(1 + \frac{7.5}{365})^{(365 \times 5)}\\\\A = \$1.63634 \times 10^{20}[/tex]
Hence, the account balance after a period of 5 years will be $1.63634×10²⁰.

The Small Business Administration guarantees some loans. The fee for this can range up to 3.75%. On a $1M business loan, how high could the fee be?
Answers
Answer:
$37,500
Step-by-step explanation:
The amount of the fee is the product of the fee rate and the amount to which that rate is applied.
__
3.75% × $1,000,000 = 0.0375 × $1,000,000 = 37.5 × $1000
= $37,500
The fee on a $1M loan could range up to $37,500.
_____
Additional comment
If you're computing this by hand, it can be easier to (a) use scientific notation, or (b) adjust the decimal points as we have shown here. In this case, we multiplied the percentage by 1000 and divided the loan amount by 1000. The product remains the same, but the numbers are easier to deal with.
In scientific notation, this is 3.75E-2 × 1E6 = 3.75E4 = 37.5E3 = 37,500, where the "E" notation would be that used by a calculator or spreadsheet.

Step-by-step explanation:
So you know the gradient of the line is -3/2x since that is the gradient.

Then, substitute the co-ordinates to find c so:
-3 = -3/2 +c

Can somebody help me find the area of this composite shape
Answers
Alone, this shape cannot have the area solved in one step. So, you must break it up into multiple pieces.
For this, we can break it up into a rectangle, and a right triangle.
The area formula for a rectangle is [tex]area = l*w[/tex]
The area formula for a right triangle is [tex]area = \frac{1}2} b*h[/tex]
To find the area of the rectangle, multiply 14 * 18 = 252 m^2
To find the length of the triangle, subtract 20 - 14 = 6
To find the height of the triangle, subtract 18 - 11 = 7
So, it is [tex]\frac{1}{2} 6*7[/tex] = 21 m^2
21 + 252 = 273 meters squared

so if you do 10+7 which equal 17 and then do 17-7 you will get ten
m=17
have a good day
Answer:
the answer is -3
Step-by-step explanation:
10 = 7 -m
swap sides so that all the variable terms are on the left hand side
7 - m =10
subtract 7 from both sides
-m + 10 - 7
subtract 7 from 10 to get 3
multiply both sides by -1

3. the stem-and-leaf plot shows the cost of lamps at a department store.

(b) is there a mode? if so, what is it?
(c) what is the difference between the most expensive and least expensive lamps?
(d) how many lamps cost more than $20 but less than $40?
(e) what is the ratio of lamps that cost less than $40 to lamps that cost more than $40? write the ratio in simplest form.
Answers
Answer:
I don't know F but if y'all do let me now.
Step-by-step explanation:
(b) the price in the very middle of a data set, with exactly half of the houses priced for less and half priced for more.
(c) The mode is the value that appears most frequently in a data set. A set of data may have one mode, more than one mode, or no mode at all. Other popular measures of central tendency include the mean, or the average of a set, and the median, the middle value in a set.
(d) The two biggest things that come to mind right away is how is it going to be used and who is going to be using it? While we would all love to get the highest quality that’s just not always possible. So, that’s a good starting point for me is considering the answer to those two questions.
(e) Price and other details may vary based on product size and color.
The difference between the most and least expensive lamps represented on the stem and leaf plot is 66.
The median costThe stem and leaf plot that completes the question is added as an attachment.
The median cost is the leaf element at the middle.
The plot has 18 leaves.
So, the median position is:
Median = (18 + 1)/2 = 9.5th
This means that the median is the mean of the 9th and the 10th items.
So, we have:
Median = (58 + 58)/2
Median = 58
Hence, the median cost is $58
The modal costThis is the element with the highest frequency in the plot.
From the attached plot 65 has the highest frequency of 3
Hence, the modal cost is 65
The difference between the most and least expensive lampsFrom the plot, we have:
Most expensive = 78
Least expensive = 12
The difference (d) is:
d = 78 - 12
d = 66
Hence, the difference between the most and least expensive lamps is 66.
Number of lamps that cost more than $20 but less than $40This means that we check the items in the range 20 to 40 (exclusive)
The elements in this range are:
25, 28, 30, 32 and 34
Hence, 5 lamps that cost more than $20 but less than $40
Ratio of lamps that cost less than $40 to more than $40From the plot, we have:
Less than $40 = 6
More than $40 = 12
The ratio is represented as:
Ratio = 6 : 12
Simplify
Ratio = 1 : 2
Hence, the ratio of lamps that cost less than $40 to more than $40 is 1 : 2

Answers
A solid line passes through (-1, 0) and (0, 3). The area to the left of the line is shaded gray.
How to get the graph of the inequality?
Here we have the inequality:
3y - 9x ≥ 9
First, we should isolate y on one side of the inequality.
3y ≥ 9x + 9
y ≥ 3x + 3
Then, the graph will be a solid line of the form:
y = 3x + 3
Where the line is solid because the points on the line are solutions, and we need to shade all the region above the line.
Also, notice that for the line:
y = 3x + 3
if x = -1 we have:
y = 3*(-1) + 3 = 0
if x = 0 we have:
y = 3*0 + 3 = 3
Then the line passes through (0, 3) and (-1, 0). So the correct option is the second one.
