Answer: [tex]\frac{1}{3}\ s[/tex]

Step-by-step explanation:

Given

Distance traveled is [tex]s=30t^2+440t[/tex]

for s=150 ft

[tex]\Rightarrow 30t^2+440t=150[/tex]

[tex]\Rightarrow 30t^2+440t-150=0\\\Rightarrow 3t^2+44t-15=0\\\Rightarrow (3t-1)(t+15)=0\\\Rightarrow t=\dfrac{1}{3}\ s[/tex]

Answer:

4. 300    5. 7     6.  2

Step-by-step explanation:

In order to solve these problems, we need to plug in x for the missing number. So, we would set it up like this:

[tex]\frac{60 mi}{1 hr} =\frac{x}{5 hr}[/tex]

We would then cross multiply in order to find the value of x. Like this:

60 × 5 = 300

1 × x = 1x

300 = 1x

300 = x

So now we know that x is 300.

We would do the exact same thing for the next question. Plug in x, then solve by cross multiplying:

[tex]\frac{8 hr}{2 days} =\frac{28 hr}{x}[/tex]

8 × x = 8x

2 × 28 = 56

8x = 56

÷8    ÷8

x = 7

We now know that x is 7.

Try the last one on your own. Do the exact same thing I did for the first two. I hope you understand a bit better now. Please let me know if you need any more help. Good luck!

Answer:

the solution is (-8, 4)

Step-by-step explanation:

Let's use the addition/subtraction method here to eliminate one variable:

-x+y=4

x+3y=4

Combining these two equations results in

4y = 8, so that y = 2.  Substituting y = 2 into the second equation, we get:

x + 3(2) = 4, or x = -2.

Then the solution is (-8, 4)

Answer:

it means that his equation is not true.

Step-by-step explanation:

-2=2 is obviously incorrect, so we must assume that the equation isn't true.

Therefore , the solution of the given problem of triangle comes out to be triangle C has the largest area 4.5 square unit.

Because a triangular has two or more extra parts, it is a polygon. It's shape is a simple rectangular. The only three edges that distinguish a triangle from just a triangle are A, B, and C. A singular area rather than a cube is produced by Euclidean geometry when the edges are not perfectly collinear. A shape is referred to as triangular if it has three sides and three angles. An angle is the point where a quadrilateral's three sides meet. A triangle's sides add up to 180 degrees.

Here,

The largest triangle ,

area wise is:

Triangle C area is:

=> 1/2 *  b * h

=> 1/2 * 3*3

=> 9/2

=> 4.5 square unit

which is the largest area as all the other triangles have 4 square unit area.

Answer:

[tex]\Huge\boxed{D}[/tex]

Step-by-step explanation:

Hello There!

To find the answer we want to find the trigonometric ratio for each answer choice

important note;

[tex]sin =\frac{opposite}{hypotenuse} \\\\cos=\frac{adjacent}{hypotenuse} \\\\tan=\frac{opposite}{adjacent}[/tex]

for A,

the opposite of angle X is  12 and the adjacent of angle x is 5

so [tex]tanX=\frac{12}{5}[/tex] therefore A is not the answer

for B,

the adjacent of angle x is 5 and the hypotenuse is 13

so [tex]cosX=\frac{5}{13}[/tex] therefore B is not the answer

for C,

the opposite of angle W is 5 and the adjacent of angle W is 12

so [tex]tanW=\frac{5}{12}[/tex] therefore C is not your answer

for D,

the adjacent of angle W is 12 and the hypotenuse is 13

so [tex]cosW=\frac{12}{13}[/tex] therefore D is your answer

Answer:

6.9

Step-by-step explanation:

The total payment was 44.35 and Ella bought 6 bags of apples and eggs

eggs cost 2.95 so apples cost 44.35-2.95=41.4

lets call bags "x"

so

6x=41.4 (price)

divide both by 6

x=6.9
