Use a quadratic equation to find two real numbers with a sum of 43 and a product of 306

Answer:

Step-by-step explanation:

Volume of the cone, V=1/3*Π*r^2*h

we have the slant height, and we need to find the h, height

a^+b^2=c^2

where c is 13

169=25+h^2

h^2=144

h=12

V=1/3*3.14*25*12=100*3.14=314.15 ft^3

Answer:

y = mx + b

explanation:

[tex]m = \frac{y2 - y1}{x2 - x1} \\ \frac{5 - 3}{1 - 0} = m \\ m = 2[/tex]

Answer:

y = 2x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (2, 7) ← 2 points on the line

m = [tex]\frac{7-3}{2-0}[/tex] = [tex]\frac{4}{2}[/tex] = 2

The line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = 2x + 3 ← equation of line

Step-by-step explanation:

`) y=500-10x

y is how much water is left in the tub

the 500 is how many gallons of water is already in the tub

-10x is how much water is drained every minute

2) plug in 16.5

y=500-10*16.5

y=500-165

y=335

335 gallons left

3) make y 0 because that represents how many gallons are in the tub

0=500-10x

-500=-10x

/-10

x=50

50 minutes

Answer:

Step-by-step explanation:

In the first triangle, using Pythagorean's theorem, x^2+3^2=5^2, x = 4

In the second triangle, using Pythagorean's theorem, x^2+7^2=24^2, x = 25

In the third triangle, using Pythagorean's theorem, 8^2+15^2=x^2, x = 17

In the fourth triangle, using Pythagorean's theorem, x^2+8^2=10^2, x = 6

In the fifth triangle, using Pythagorean's theorem, 5^2+12^2=x^2, x = 13

The number of students in the school could Jimmy predict would choose history as their favorite subject is 500.

In statistics, a simple random sample is a subset of people chosen at random from a larger group, all of whom were chosen with the same probability. It is a method of choosing a sample at random.

Given that, there are 625 students in Weaver Junior High School.

24 of the 30 students surveyed liked history.

The students surveyed liked history

=24/30 ×100

= 0.8×100  

= 80%

Now,  80% of 625 students

625 × 0.8 = 500

So, 500 of the total students like history

Therefore, the number of students in the school could Jimmy predict would choose history as their favorite subject is 500.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

I did it.

Answer:

a. 28.8

Step-by-step explanation:

Using the theorem of similarity, the following equation can be generated:

[tex] \frac{x}{12} = \frac{25 + 35}{25} [/tex]

Solve for x

[tex] \frac{x}{12} = \frac{60}{25} [/tex]

Cross multiply

[tex] x*25 = 60*12 [/tex]

[tex] 25x = 720 [/tex]

Divide both sides by 25

x = 28.8

Answer:

g(10) = - 4+

Step-by-step explanation:

Given

g(n) = - 4n - 3

Now

g(10)= - 4 * 10 - 3

= -40 - 3

= -43

Hope it will help :)

Step-by-step explanation:

Hey there!

Given;

g(n) = -4n-3

And to find: g(10)

Simply replace "n" by "10" on every place where there is "n". So,

g(n) = -4n-3

~Replace by "10".

g(10) = -4*10-3

= -40-3

= -43

Therefore, g(10) = -43.

w=5

Step-by-step explanation:

Solve for W by getting it by itself.

1. Divide both sides by -4.

(w + 1)= -24/-4

2. Simplify

(w + 1)= 6

3. Subtract 1 from both sides.

w= 6-1

w= 5

Answer:

Time remain = 85/24 hours

Step-by-step explanation:

Given:

Total time taken by April = [tex]7\frac{3}{8}[/tex] hours

Time she already drive = [tex]3\frac{5}{6}[/tex] hours

Find:

Time remain

Computation:

Time remain = Total time taken by April - Time she already drive

Time remain = [tex]7\frac{3}{8}[/tex] hours - [tex]3\frac{5}{6}[/tex] hours

Time remain = 85/24 hours

Answer:

y = - 9

Step-by-step explanation:

Substitute in -1 for x

8(-1) - 2y = 10

-8 - 2y = 10

Subtract -8 from both sides

-8 - (-8) cancels out to 0

10 - (-8) = 18

We are left with:

-2y = 18

Divide by -2 on both sides.

-2y/-2 = y

18/-2 = -9

y = -9

m = 13/30

Step-by-step explanation:

2/5 + m = 5/6

m + 2/5 = 5/6

m + 2/5 - 2/5 = 5/6 - 2/5

m = 13/30

Answer:

M = 13/30

Step-by-step explanation:

2/5 + m = 5/6

Subtract 2/5 from both sides

m = 13/30
