Answer:

30ft

Step-by-step explanation:

i think by common sense as an high schooler

8 times 5 equals 40ft and 6 times 5 equals 30 ft

Answer:

4x-6y-12=0 than it passes through the origin so.distance equals /ax+by+c/all over a^2+ b^2= 4(0)+6(0)-12/4^2+6^2= -12/16+36=12/52=0.23077

Answer:

(L • W)(x) = 12x^3 − 20x^2 + 24x (the last option)

Step-by-step explanation:

It's very simple actually. To find an area of a rectangle, all we have to do is multiply its two sides. We are given the length and the width of the rectangle - its sides. All we have to do is simply multiply them:
Area = L(x) * W(x)
L(x) = 4x
W(x) = 3x^2 - 5x + 6
Therefore the area is equal to:
(4x) * (3x^2 - 5x + 6) =
= 4x * 3x^2 - 4x * 5x + 6 * 4x =
= 12x^3 - 20x^2 + 24x
And there's your answer, option D, or 4 or whatever you call the last one.

Answer:

8:40 a.m.

Step-by-step explanation:

Let's start by finding the time John should arrive at school.

9:00 a.m. - 5 minutes = 8:60 a.m. - 5 minutes = 8:55 a.m.

Note that there are 60 minutes in an hour

Now, we find the time he should leave home...

8:55 a.m. - 15 min = 8:40 a.m.

Therefore John should leave at 8:40 a.m.

Another way to solve this problem:

John needs to leave home in "x" minutes before 9:00 a.m. to arrive when the bell rings (9:00 a.m.). To find "x", we need to add 15 and 5 to get:

15 min + 5 min = 20 min.

Therefore he must arrive 20 minutes before 9:00 a.m.

9:00 a.m. - 20 min = 8:40 a.m.

Therefore John should leave at 8:40 a.m.

Answer:

b

Step-by-step explanation:

because u will subtract 0.5 from 8 nine times

8-0.5= 7.5

7.5-0.5=7.0

7.0-0.5= 6.5

6.5-0.5=6.0

6.0-0.5=5.5

5.5-0.5=5.0

5.0-0.5=4.5

4.5-0.5=4.0

4.0-0.5=3.5

The cost of the mp3 player after the discount is $27.98.

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by whole and multiply by 100.

Given

An mp3 player is on sale for 30% off the regular price of $39. 98.

The price of the mp3 player after the 30% is given

[tex]\rm Cost \ of \ player \ after \ discount = Cost \ of \ player \times discount\\\\\rm Cost \ of \ player \ after \ discount = 39.98\times 0.30\\\\\rm Cost \ of \ player \ after \ discount = 11.99[/tex]

The cost of mp3 player after 30% discount is;

= $39.98 - $11.99 = $27.98

Hence, the cost of the mp3 player after the discount is $27.98.

Answer:

  C.  2y = (2x-1)/4

Step-by-step explanation:

An equation is linear when the exponents of the variables are 1 and the sum of the exponents of the variables in any term is 1.

a) 3xy = 4 . . . . sum of exponents is 1+1=2

b) f(x) = 2/3(1 -x^2) . . . . exponent is 2

c) 2y = (2x -1)/4 . . . . all exponents are 1 (linear)

d) y = 3/(x+1)  ⇒  xy +y = 3 . . . . sum of exponents is 1+1 = 2

Answer:

[tex]x=2\sqrt5[/tex]

Step-by-step explanation:

I'm assuming that 15 is the length of only part of the hypotenuse of the larger triangle.

The remaining part can be easily found by noticing that the red triangle is half an equilateral triangle of side x, so the missing part is x/2.

Now for a known theorem (easily proved with the fact that triangles AHC and ABC are similar) you can write the following equation containing x:

[tex]x^2 = \frac x2 ( \frac x2 +15) \rightarrowx^2 = \frac {x^2}4+15 \\\\3x^2=60 \rightarrow x^2 = 20 \\x=2\sqrt5[/tex]

(where we obviously took only the positive root since x is a lengtth measure.

Answer:

12.3

Step-by-step explanation:

Use the law of sines.

[tex] \dfrac{a}{\sin A} = \dfrac{b}{\sin B} [/tex]

[tex] \dfrac{14}{\sin 80^\circ} = \dfrac{x}{\sin 60^\circ} [/tex]

[tex] x = \dfrac{14\sin 60^\circ}{\sin 80^\circ} [/tex]

[tex] x = 12.3~cm [/tex]

Answer:

C 60 inches

Step-by-step -

60 x 2 = 120, which is both lengths, and since he width is half the length, then 30 x 2 = 60. So 130 (length) + 60 (width) = 180. So 60 inches would be the maximum length for both sides.

Given that,

Time taken by Hua to complete her homework is 35 minutes

ATQ,

The time taken by Carrie is five less minutes than twice the amount of time as Hua to complete her homework. Let it is x minutes.

The numerical expression for this is given by :

x = 2(times taken by Hua)-5

x = 2(35)-2

Above is the numerical expression for time taken by Carrie.

We can also solve it, x = 70-2 = 68 minutes

Hence, this is the required solution.
