1: -126=14k
2: -7+m=8
3: -17=x -15
4: -5=a/18

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

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

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]

Have a super awesome day!

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. :)

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%

in this way you can solve this

Answer:

691

Step-by-step explanation:

Henry would have $1,005.94 more than Ethan in his account after 9 years.

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.
