The sum of three numbers is 89 The second number is 6 times the first. The third number is 15 less than the second. What is the first number?

Answers

Answer 1

The first number is 8

Solution:

Let the first number be "x"

The second number is 6 times the first

Second number = 6x

The third number is 15 less than the second

Third number = second number - 15

Third number = 6x - 15

The sum of three numbers is 89

Therefore,

First number + second number + third number = 89

[tex]x + 6x + 6x - 15 = 89\\\\13x - 15 = 89\\\\13x = 89+15\\\\13x = 104\\\\Divide\ both\ sides\ by\ 13\\\\x = 8[/tex]

Thus the first number is 8

A solid figure is
separated into two rectangular prisms.
The volume of Rectangular Prism A is
80 cubic feet. Rectangular Prism B has
a length of 6 feet and a width of 5 feet.
The total volume of the solid figure is
200 cubic feet. What is the height of
Rectangular Prism B? Show your work
and explain your answer.
Thank you!

Answers

Answer: 4 feet.

Step-by-step explanation:

Their is one rectangular prison divided into two.

The volume of the first one is

V1= L X H X W=80.

Volume of the second one is

V2= L X H X W

V2= 6 X H X 5

V2 = 30H

Now from the question, the total volume is 200cubic feet which means V1 + V2 = 200, recall that V1=80 and V2=30H, so we say;

80+30H=200, collecting the like term we have, 30H=200-80.

30H=120, divide both side by 30

30H/30=120/30

H= 4feet.

Height is 4feet.

Final answer:

To find the height of Rectangular Prism B, subtract Rectangular Prism A's volume from the total volume to get Prism B's volume (120 cubic feet), then divide by the product of its length and width. The height is 4 feet.

Explanation:

The question is about finding the height of Rectangular Prism B given that the solid figure it's part of (when combined with Rectangular Prism A) has a total volume of 200 cubic feet, and that Rectangular Prism A has a volume of 80 cubic feet. Considering volume calculations for rectangular prisms are done using length × width × height, we can find the height of Prism B by isolating height in the formula. Since Prism B has a length of 6 feet and a width of 5 feet, and we know the combined volume of both prisms, we first subtract the volume of Prism A from the total volume to find the volume of Prism B, which is 120 cubic feet (200 cubic feet - 80 cubic feet).

Volume of Prism B = 120 cubic feet. The formula for volume is then applied as follows:

Volume = Length × Width × Height

120 cubic feet = 6 feet × 5 feet × Height

Height = 120 cubic feet / (6 feet × 5 feet)

Height = 120 cubic feet / 30 square feet

Height = 4 feet.

Therefore, the height of Rectangular Prism B is 4 feet.

What is the volume of the cone to the nearest whole number?
A) 31 m3
B) 94 m3
C) 188 m3
D) 283 m3

Answers

Answer:

It is 94

Step-by-step explanation:

The volume of a cone with a height of 10 meters and a radius of 3 meters is

94 m³.

What is a cone?

A cone is a three-dimensional geometric shape with a smooth and curving surface and a flat base, with an increase in the height radius of a cone decreasing to a certain point.

The volume of a cone is (1/3)πr²h.

The total surface area of a cone is πr(r + l).

The curved surface area is πrl.

Given, A cone has a radius of 3 meters and a height of 10 meters.

Therefore, The volume of this cone is,

= (1/3)π(3)²×10 m³.

= 30π m³.

= 30×3.14 m³.

= 94.2 m³ or 94 m³.

D. p=376+421

Answers

The equation shows how to find the percent increase:

[tex]Percent\ increase = \frac{421-376}{376} \times 100[/tex]

Solution:

Given that,

A town’s population of children increased from 376 to 421 during the past year

To find: percent increase

The percent increase is given by formula:

[tex]\text{Percent increase} = \frac{\text{Final value - initial value}}{\text{initial value}} \times 100[/tex]

From given,

Initial value = 376

Final value = 421

[tex]Percent\ increase = \frac{421-376}{376} \times 100\\\\Percent\ increase = \frac{45}{376} \times 100\\\\Percent\ increase = 11.968 \%[/tex]

Which value of the makes \dfrac{8+h}{10}=1
10
8+h

=1start fraction, 8, plus, h, divided by, 10, end fraction, equal, 1 a true statement?

Answers

Answer:

h = 2

Step-by-step explanation:

(8+h)/10 = 1

8+h = 1×10

8+h = 10

h = 10-8

h = 2

The value of h that makes the equation [tex]\(\frac{8+h}{10} = 1\)[/tex] true is (h = 2).h=2 is the value that, when substituted into the equation, ensures that the left side of the equation (8+h) is equal to the right side (10 times 1).

To find the value of h that satisfies the

equation: [tex]\(\frac{8+h}{10} = 1\)[/tex],

we can start by understanding the equation. It represents a fraction where the numerator is the sum of 8 and h, and the denominator is 10. The fraction is set equal to 1, which means both sides of the equation should be equal.

To solve for h, we can cross-multiply, which simplifies to

(8 + h = 10)

Now, to isolate h, we need to get it on one side of the equation. Subtracting 8 from both sides yields (h = 2).

So, when h = 2, the equation becomes

[tex]\(\frac{8+2}{10} = 1\)[/tex] , which simplifies to [tex]\(\frac{10}{10} = 1\)[/tex],

making it a true statement.

In essence, h=2 is the value that, when substituted into the equation, ensures that the left side of the equation (8+h) is equal to the right side (10 times 1). This demonstrates the solution's validity and satisfies the equation's condition.

Scott invested a total of $5900 at two separate banks. One bank pays simple interest of 12% per year while the other pays simple interest at a rate of 6% per year. If
Scott earned $540.00 in interest during a single year, how much did he have on deposit in each bank?
Scott had $ 2,800 on deposit at the bank that payed 12% interest.

Answers

Answer:

$3100 at 12%$2800 at 6%

Step-by-step explanation:

Let x represent the amount on deposit at 12%. Then 5900-x is the amount deposited at 6%, and the total interest earned is ...

  12%·x +6%·(5900 -x) = 540

  0.06x + 354 = 540 . . . . . . . . eliminate parentheses

  0.06x = 186 . . . . . . . . . . . . . . subtract 354

  x = 3100 . . . . . . . . . . . . . . . . . divide by 0.06

Scott invested $3100 at 12% and $2800 at 6%.

_____

Quick sanity check

The average interest earned is $540/$5900 ≈ 0.0915 ≈ 9.15%. This is more than the average of 12% and 6%, which is (12+6)/2 = 9 percent. Hence more than half of the money must be deposited at 12%.

Answers

Answer:

kiki has $4.17 and jordan has $4.14 kiki has 0.03 more than jordan

Step-by-step explanation:

If you add up the numbers for kiki you get $4.17 and if you do the same for jordan with the numbers they gave you for him you get $4.14 then you just minus 4.17 and 4.14 and thats how you get 0.03.

Answer:

Kiki has $0.03 more than Jordan, meaning Kiki has more money.

Step-by-step explanation: It's simple! Add 2.48 + 1.69 = 4.17 (This is Kiki's total amount) And then add 3.05 + 1.09 = 4.14 (This is Jordan's total amount)

As we can see, Kiki has more money. To find the difference we simply do 4.17 - 4.14 = 0.03 (:
