A garage floor measures 150 feet by 120 feet. A scale drawing of the floor on grid paper uses a scale of 1 unit and 15 feet.What

vova2212 [387]

Answer:

The dimensions of the drawing are 10 units by 8 units

Step-by-step explanation:

we know that

The scale drawing is $\frac{1}{15}\ \frac{unit}{feet}$

That means ---> 1 unit in the drawing represent 15 feet in the actual

To find out the dimensions of the drawing, multiply the actual dimensions by the scale drawing

so

$150\ ft=150(\frac{1}{15})=10\ units$

$120\ ft=120(\frac{1}{15})=8\ units$

therefore

The dimensions of the drawing are 10 units by 8 units

Answer:

He made 5 2-pointers and 4 3-pointers

Step-by-step explanation:

Let x = number of 2-pointers he scored.

Let y = number of 3 pointers he scored.

The total number of shots he made is x + y, and it it equals 9.

The first equation is

x + y = 9

The total number of points he scored on 2-pointers is 2x. The total number of points he scored on 3-pointers is 3y. The total number of points he scored with 2-pointers and 3-pointers is 2x + 3y. It equals 22.

The second equation is

2x + 3y = 22

We have a system of 2 equations.

x + y = 9

2x + 3y = 22

We will use the substitution method.

Solve the first equation for x.

x = 9 - y

Now substitute 9 - y in for x in the second equation.

2x + 3y = 22

2(9 - y) + 3y = 22

18 - 2y + 3y = 22

y + 18 = 22

y = 4

Now we substitute 4 for y in the first equation and solve for x.

x + y = 9

x + 4 = 9

x = 5

Answer: He made 5 2-pointers and 4 3-pointers

Check:

5 2-pointers and 4 3-popinters are a total of 9 shots, so the number of shots is correct.

Now we check the number of points.

5 * 2 + 4 * 3 = 10 + 12 = 22

22 points is the correct total.

Our answer is correct.

Answer:

Option B.

Step-by-step explanation:

If a quadratic equation is defined as

$ax^2+bx+c=0$ .... (1)

then the quadratic formula is

$x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

The given equation is

$10x^2=6+9x$

It can rewritten as

$10x^2-9x-6=0$ .... (2)

On comparing (1) and (2) we get

$a=10,b=-9,c=-6$

Using quadratic formula we get

$x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(10)(-6)}}{2(10)}$

$x=\dfrac{9\pm \sqrt{81+240}}{20}$

$x=\dfrac{9\pm \sqrt{321}}{20}$

Therefore, the correct option is B.
