Q:An athlete throws her javelin 9.5 yards. She throws it this distance 2 times. How far does she throw the javelin in total?
18.5 yd
19 yd
19.5 yd
20 yd

Answer:

D. 2

Step-by-step explanation:

DEFG is a trapezoid and AB is its Midsegment.

Therefore,

[tex]AB =\frac{1}{2}(DG + EF) \\ \\ 12 = \frac{1}{2} (5x - 4 + 8x + 2) \\ \\ 12 \times 2= (13x - 2) \\ \\ 24 = 13x - 2 \\ \\ 24 + 2 = 13x \\ \\ 26 = 13x \\ \\ x = \frac{26}{13} \\ \\ x = 2[/tex]

The answer is .25 kilometers a minute.

This is because [tex]speed = \frac{distance}{time}[/tex] so you need substitute then divide to find the answer

You can check this answer by doing 15÷60 which comes out to .25 km a minute.

Answer:0.25m per minute

Step-by-step explanation:

You divided the 15 by the 60 since 15 is the km and 60 minutes and you want to know how far can she run in minutes

Hope this helped :)

Answer:

please brain or heart me im about to level up

Answer:

Step-by-step explanation:

well just go throught the factors as far as you can ik from my personal mindset that 14*14= 196 so if i go bk and  calculate 13*13=169 which means its gonna be in between 13 and 14. so to figure this out we have to write it out. so we can try 13.5*13.5=182.25 so we have to go higher  13.89*13.89=192.9321 which means it has to be 13.89 rounded to the nearest hundreth.

Answer:

27 m

Step-by-step explanation:

The position of a body is given by :

[tex]s=t^3 - 12t^2 + 36t[/tex]

We need to find the total distance traveled by the body from t=0 to t=3.

At t = 0,

[tex]s=0^3 - 12(0)^2 + 36(0)=0\ m[/tex]

At t = 3 s,

[tex]s=(3)^3 - 12(3)^2 + 36(3)\\\\=27\ m[/tex]

So, the total distance from t=0 to t=3 is equal to 27 m.

Answer:

$16.50

Step-by-step explanation:

Take the total price, convert the percentage to a decimal and multiply the two together.

329.97*0.05=16.498

Round to the nearest cent.

$16.50

Answer:

346.47

Step-by-step explanation:

the equation is: 329.97 * 5/100 + 329.97

= 16.4985 +329.97=346.4685

rounding to the nearest cent we get 346.47

= 157.

circumference of circle feet is 157 × 12 inches.

Step-by-step explanation:

consider the following formula to find the circumference of circle

C= 2^_r

here r is radius of circle

the radius of circular is 25 ft.

Therefore circumference is as follows

C = 2^_r

Answer: if x is to the 2 power then

kx^2+12x-4=0         Add 4 to the both sides

kx^2+12x=4             Divide both sides by 12

kx^2=1/3x                square root the both sides

k=0.6x

Answer:

184

Step-by-step explanation:

920 divided by 5 is 184 which makes it unit rate

Answer:

55

Step-by-step explanation:

a triangle adds up to 180°

25+30+x= 180

55+x=180

x=180-55

x=125

x and y is a straight line so it adds up to 180°

x=125 y=?

x+y=180

125+y=180

y=180-125

y=55°

y= 55°

Answer:

the coefficient of the squared expression in the parabolas equation: D. 3

Step-by-step explanation:

y = a (x-h)² + k        parabola equation

y=-1 and x=3    vertex(h,k): (2,-4)

-1 = a * (3-2)² + (-4)

-1 = a - 4

a = -1 + 4 = 3

equation: y = 3 * (x-2)² -4

Answer:

d !

Step-by-step explanation:

Answer:

Here we have:

g(x) = 3*f( 2*x - 2) - 1

We want to know the horizontal translation used here.

We need to discuss two types of transformations here.

horizontal translation.

If we have a function f(x), a horizontal translation of N units is written as:

g(x) = f(x + N)

if N is negative, the translation is to the right.

if N is positive, the translation is to the left.

Horizontal dilation.

For a function f(x) an horizontal dilation of scale factor k is written as:

g(x) = f( x/k)

You can see that in our function we have both of these transformations.

Because we compare the translation with f(x), we assume that the horizontal translation is the first thing we did, then we must have

translation:

g(x) = f(x + N)

and now a horizontal dilation of scale factor k

g(x) = f( (x + N)/k)

Then we must have that the argument of the above function is the same as the argument of the given function.

(x + N)/k = 2*x - 2

then:

k = 1/2

(x + N)/1/2 = 2*x + 2*N = 2*x - 2

2*N = -2

N = -2/2 = -1

This means that we have a translation of 1 unit to the right.

Answer:

(4 * 8y) - (4 * 12)

Step-by-step explanation:

We have the equation 4(8y - 12) and are asked to expand, this equation can be solved through distribution, and to expand it, we need to separate the "4" to multiplying into "8y" and "-12"

Therefore :

(4 * 8y)(4 * -12)

Now this may seem correct, but we have to keep in mind that we are not multiplying both answers within the parenthesis but yet subtracting, therefore :

(4 * 8y) - (4 * 12)

Answer:

8 peanut cookies

Step-by-step explanation:

4 x 12  = 48

48 x  1/3 = 2/3 left             (16 chocolate chip)

48-16= 2/3 = 32 left          

32 x 3/4 = 24                     (24 gingersnaps)

32-24 = 8                          ( 8 peanut cookies)

Answer:

Step-by-step explanation:

[tex] \frac{3}{4} x - 7 = 3( \frac{1}{6} x + 1)[/tex]

[tex] = > \frac{3}{4} x - 7 = \frac{1}{2} x + 3[/tex]

[tex] = > \frac{3}{4} x - \frac{1}{2} x = 3 + 7[/tex]

[tex] = > \frac{3 - 2}{4} x = 10[/tex]

[tex] = > \frac{1}{4} x = 10[/tex]

=> x = 10 × 4

=> x = 40

Here,

The variable x whose only one value 40 will solve the equation.

Hence,

It has only one solution. (Ans)

Answer:

subtracting 14 from sides of the number sentence

Step-by-step explanation:

14 + n = 84

Since 14 is being added to n, you need to subtract 14 from both sides to solve for n.

Answer: subtracting 14 from sides of the number sentence

Answer:

The correct option is 3.

Step-by-step explanation:

By multiplying each side by -8, you can get rid of the fraction. Then by subtracting 35 from both sides, you get what is x.
