Answer:
1. k = -9
2. m = 15
3. x = -2
4. a = -90
Step-by-step explanation:
When doing these problems set them up as if the equal sign is a dividing line between two sides.
1. -126=14k
Divide both sides by 14 to get rid of the coefficient.
This gives you your answer -9=k
2. -7+m=8
Add 7 to both sides to isolate the variable.
This gives you your answer m=15
3. -17=x-15
Add 15 to both sides to isolate the variable.
This gives you your answer x=-2
4. -5=a/18
Multiply both sides by 18 to get rid of the denominator.
This gives you your answer of a=-90

Answer:
577.50
Step-by-step explanation:
You need to add all the areas of the separate pieces together, so the triangles are:
Triangle: 7 (12) (1/2), but you have 2 of them so don't divide by 2, just 7(12) so that part is 84
Top flap is 15(7) = 105
Middle is 15(12) = 180
Bottom is 15(13.89) = 208.35
Add them all together 84+105+180+208.35 = 577.50
1. Classify the triangle
A isosceles acute
B isosceles obtuse
C scalene acute
D scalene obtuse

show that the equation x^3 + x - 3 has a solution between 1 and 2
Answer:
see explanation
Step-by-step explanation:
Evaluate the polynomial at x = 1 and x = 2
x = 1 : 1³ + 1 - 3 = 1 + 1 - 3 = - 1
x = 2 : 2³ + 2 - 3 = 8 + 2 - 3 = 7
Then ( 1, - 1 ) → (2, 7 )
Shows the polynomial goes from y = - 1 to y = + 7
The change in sign indicates the graph crosses the x- axis between 1 and 2
Thus indicating a solution between x = 1 and x = 2

Mark spends $36 at a basketball game. He buys a T-shirt for $22. He then buys a bottle of water for $4 and 2 tacos. How much is each taco?
Answer:
each taco is $7.
Step-by-step explanation:
In total he spent $36. He bought a shirt for $22 and a bottle of water for $4.
22+4= 26
36-22= 14
14 divided by 2= 7
Answer:
each taco is $5.
Step-by-step explanation:
Let's think about like Mark starts off with $36. Take away $22 for that t-shirt he bought. Now he has $14. He uses $4 for water, now he has $10. The rest of his money is spent on tacos. $10/2 tacos is $5 for each taco. :)

Find the area of each figure.
Answer:
Figure 1's area is 530.66 centimeters and figure two's is 1589.6250 centimeters
Hey there!
The answers are 706.5 and 1589.625
The formula for the area of a circle is [tex]\pi[/tex][tex]r^2[/tex].
For the first circle, the radius is 15, so let's solve:
[tex]\pi (15^2)[/tex]
[tex]\pi(225)\\3.14(225)\\\\706.5[/tex]
The second circle has a diameter of 45, and the radius is half the diameter, so 45/2 = 22.5. Let's solve:
[tex]\pi (22.5^2)\\\pi (506.25)\\3.14(506.25)\\1589.625[/tex]

A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff
Answer:
114%
Step-by-step explanation:
A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff?
Percentage Formula is given as:
New value - Old value/Old value × 100%
New value = 214
Old value = 100
Hence:
Percentage increase = 214 - 100/100 × 100
= 114/100 × 100
= 114 %
Therefore, the percentage increase = 114%

Ethan invested $9,500 in an account paying an interest rate of 2 3/4% compounded monthly. Henry invested $9,500 in an account paying an interest rate of 3 3/8% compounded quarterly. After 9 years, how much more money would Henry have in his account than Ethan, to the nearest dollar?
Answer:
691
Step-by-step explanation:
Henry would have $1,005.94 more than Ethan in his account after 9 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To solve this problem, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^(^n^t^)[/tex]
where A is the amount after t years,
P is the principal
r is the annual interest rate,
n is the number of times the interest is compounded per year, and
t is the time in years.
For Ethan:
P = $9,500, r = 2.75% = 0.0275 (since it is compounded monthly, n = 12), and t = 9
[tex]A = 9,500(1 + 0.0275/12)^(^1^2^\times^9^)[/tex]
= $12,817.84
For Henry:
P = $9,500,
r = 3.375% = 0.03375 (since it is compounded quarterly, n = 4), and
t = 9
[tex]A = 9,500(1 + 0.03375/4)^(^4^\times^9^)[/tex]
= $13,823.78
The difference in the amounts is:
$13,823.78 - $12,817.84 = $1,005.94
Therefore, Henry would have $1,005.94 more than Ethan in his account after 9 years.
