6. In a basketball fundraiser, Jasmine can makes 10 free throws per minute. She is sponsored for
$16.25 for each free throw she makes. Draw a graph to show how much money she would earn over
the five minutes of the shootathon.
a) How much did Jasmine raise during the shootathon?
​

Answer:

(x+2)(x+6)

Step-by-step explanation:

that is the answer because math

=>x^2+8x+12

=>x^2+6x+2x+12

=>x(x+6)+2(x+6)

=>(x+6)(x+2)

Hope it helps you

Answer:

x = 0

Step-by-step explanation:

The axis of the symmetry has the same x coordinate of the vertex

V (x) = -b/2a

in both equations b is equal to 0 and a 0/a number different from 0 gives always 0 as a result

Step-by-step explanation:

Formula to ind surface area of cylinder:

[tex]A=2\pi \frac{d}{2} h+2\pi (\frac{d}{2} )^{2}[/tex]

[tex]A=2\pi \frac{10}{2} (30)+2\pi (\frac{10}{2} )^{2}[/tex]

[tex]A=1099.557443cm^{2}[/tex]

Therefore, area will be:

Answer:

56

Step-by-step explanation:

Think of it this way, 7 times 10 is 70.

7*8 is 2 less 7s, or 14 less.

70-14=56

Or, a simpler way:

7*7 is 49(perfect square)

One more seven than that is 56.

These are just two ways I quikcly remember, because for some reason I struggle with 7 and 8 mulitplication.

Hope this helps!

Answer:

Step-by-step explanation:

according to the multiplication table

7 times 8'gives 56

Answer:

58

Step-by-step explanation:

Area = Area of entire recangle - area of cut out

a = (10 * 7) - (6 * 2)

a = 70 - 12

a = 58

Answer:

24

Step-by-step explanation:

Step-by-step explanation:

3^3 which also equals 27 -3 which has a total of 24

Answer:

2 km/h

Step-by-step explanation:

Let

Rate of river current = x km/h

Speed of Peter's boat = 4x km/h

He takes 15 km trip up (opposite direction)

His speed upstream = 4x - x

= 3x

His speed is 3x and distance is 15 km

Time = Distance / Speed

15/3x

= 5/x

And

Moving downstream (same direction)

Speed will be 4x + x = 5x

Distance = 15km,

speed = 5x

Time = Distance / Speed

= 15/5x

= 3/x

Total time take for trip = 4 hours

Total time take for trip = upstream + downstream

4 =5/x + 3/x

4 = 8/x

Cross product

4 * x = 8

x = 8/4

x = 2

Rate of river current = x km/h

= 2 km/h

Step-by-step explanation:

2÷2=1

Answer:

Step-by-step explanation:

You could start by using pemdas which start with parentheses so since 3+4 is in parentheses add those first and you'll get 7 then solve the remaining 4-2 in the bracket so 4-2 is 2. Since there is no plus sign you multiply 7 by 2 then multiply by three so 7x2 is 14 then 14x3 is 42 so your answer Is 42

Answer:

1. a. miles or feet

b. inches

c. ounces

d. gallons

2. a.  1:36

b. 1/1

c. 63,360

Step-by-step explanation:

Answer:

n = 17

Step-by-step explanation:

For a quadratic equation to have equal roots b²-4ac should be equal to zero in the quadratic equation ax²+bx+c=0.

Equation : 3x² - 12 x + ( n - 5) = 0

a = 3, b = -12, c = ( n - 5)

b² - 4ac = 0

(-12)² - (4 x 3 x (n - 5)) = 0

144 - 12( n - 5 ) = 0

12( n - 5 ) = 144

n - 5 = 12

n = 17

Check if it's true :

3x² - 12 x + ( 17 - 5) = 0

3x² - 12 x + 12 = 0

3(x² - 4x + 4) = 0

(x² - 4x + 4) = 0

(x - 2)(x - 2) = 0

x = 2 , 2

Equal roots .

Answer:

x(x-5)=176

Step-by-step explanation:

If x is meant to be the greater integer, then it only makes sense to subtract five from it in order to find the value of the second integer, then multiplying them together

Answer:

119 or 118.726577

Step-by-step explanation:

We should use the Pythagorean Theorem to solve this problem.

a^2+ b^2=c^2

64^2+100^2=c^2

4096+10000=14096

c^2=14096

c=\sqrt{14096}14096

And the root of 14096 is 118.726577.

So the Answer is About 119 meters, or 118.726577

hope this helps!

Answer:

The large square covers more

Step-by-step explanation:

Given

See attachment for squares

Required

Which covers more plane

The large square has the highest dimension and by extension, it has the highest area.

This means that, less large squares will be needed to cover more areas compared to other sizes of the squares.

Take for instance, the following analysis;

Large square

Dimension: 3 by 3;

[tex]Area=3*3 = 9[/tex]

Medium Square

Dimension: 2 by 2

[tex]Area = 2 * 2 = 4[/tex]

Small square

Dimension: 1 by 1

[tex]Area = 1 * 1 = 1[/tex]

The square with the largest area covers more of the plane.

Hence, the large square covers more of the plane

Answer:

Step-by-step explanation:

Let L be the given line, then, with a slope of -8

L :  y = -8x + b

where b is to be determined from the included point A(-10,0).

Substitute point A in L to get

0 = -8 (-10) + b

solve to get

b = -80

therefore

L : y = -8x -80

Now substitute B(-9,z) in L

z = -8(-9) - 80 = -8
