Answer:

x=4

Step-by-step explanation:

0.25x+7=4(x−2)

Use the distributive property to multiply 4 by x−2.

0.25x+7=4x−8

Subtract 4x from both sides.

0.25x+7−4x=−8

Combine 0.25x and −4x to get −3.75x.

−3.75x+7=−8

Subtract 7 from both sides.

−3.75x=−8−7

Subtract 7 from −8 to get −15.

−3.75x=−15

Divide both sides by −3.75.

x=-15/-3.75

Expand -15/-3.75 by multiplying both numerator and the denominator by 100.

x=-1500/-375

Divide −1500 by −375 to get 4.

x=4

Answer:

80cm3

Step-by-step explanation:

volume of the composite solid=volume of the

pyramid+

volume of the

cuboid

volume of the pyramid=1/3* base area*height

=1/3*5*4*6

=40cm3

volume of the cuboid=base area *height

=5*4*2

=40cm3

volume of the composite solid=40cm3+40cm3

Answer:

The approximate percentage of SAT scores that are less than 865 is 16%.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean of 1060, standard deviation of 195.

Empirical Rule to estimate the approximate percentage of SAT scores that are less than 865.

865 = 1060 - 195

So 865 is one standard deviation below the mean.

Approximately 68% of the measures are within 1 standard deviation of the mean, so approximately 100 - 68 = 32% are more than 1 standard deviation from the mean. The normal distribution is symmetric, which means that approximately 32/2 = 16% are more than 1 standard deviation below the mean and approximately 16% are more than 1 standard deviation above the mean. So

The approximate percentage of SAT scores that are less than 865 is 16%.

Step-by-step explanation:

Find the Equation Using Slope-Intercept Form

Answer:

y= - (1/3) x + 9

Step-by-step explanation:

y = m x +b  === m is slope, b is y-intercept

Solve given equation for y to find parallel slope -- y = - (1/3) x + 3

so parallel slope is - (1/3)

substitute point  & slope into equation to find b

8 = - (1/3) (3) + b

b = 9

Answer:

dont mind me im just getting my points back

Step-by-step explanation:

Answer:

The invoice gets paid after 12 days, so mapplewood will get a 3% discount (3/30, 3% off if paid within 30 days). I assume that Freight doesn't get a discount,  so I subtract it from the invoice value:

$5250-$250 (freight)=$5000

Discounted invoice becomes:

$5000-3%*5000(discount)=$4850

Add the freight back to the new invoice:

$4850+$250=$5,100 if paid on April 27

B) the invoice gets paid after 36 days, so the invoice gets paid in full ( n/60; in other words, invoice paid in full if paid within 60 days, therefore $5,250)

Answer:

The length of each side of the equilateral triangle is 6.93 cm.

Step-by-step explanation:

Check the image uploaded for diagram;

The length of each side of the equilateral triangle is y;

Apply Pythagoras theorem to determine y;

[tex]y^2 = 6^2 \ + \ (\frac{y}{2} )^2\\\\y^2 = 36 \ + \ \frac{y^2}{4} \\\\multiply\ through \ by \ 4;\\\\4y^2 =144 \ + \ y^2\\\\4y^2 - y^2 = 144\\\\3y^2 = 144\\\\y^2 = \frac{144}{3} \\\\y^2 = 48\\\\y = \sqrt{48} \\\\y = 6.93\ cm[/tex]

Therefore, the length of each side of the equilateral triangle is 6.93 cm.

A equilateral triangle is the triangle in which all the three sides are of equal length in measure.

The side of the equilateral triangle is 4 centimetres. Hence the option A is the correct option.

A equilateral triangle is the triangle in which all the three sides are of equal length in measure.

The relation between the height and the side of the equilateral triangle can be given as,

[tex]a=\dfrac{2h}{\sqrt{3} }[/tex]

Given information-

An equilateral triangle has a height of 6 centimetres.

The side of the equilateral triangle which has a height of 6 centimetres can be calculate using the above formula. Thus,

[tex]a=\dfrac{2\times6}{\sqrt{3} }\\a=\dfrac{12}{3} \\a=4[/tex]

Thus the side of the equilateral triangle is 4 centimetres. Hence the option A is the correct option.

Step-by-step explanation:

Answer: 12

Step-by-step explanation:

I don't know if you mean using the Complements Method but I really wouldn't recommend using this method for all problems unless your teacher asked you to specifically.

Here is how to:

1. take the "complement" of the number we are subtracting (The "complement" is the number to add to make 10 (or 100, 1000, etc, depending on how many digits we have)

2. add it to to the number we are subtracting from

3. discard the extra "1" on the left

If you mean to do it mentally, think about it like this:

20 + (-9) = 11 You are essentially adding negative nine to twenty, not subtracting nine. If you want to see this better, try using a number line.  When you add a negative number, you move to the left on the number line.

Same thing with 8 + (-7) = 1

You are adding negative seven to eight.

All that is left to do is adding both of the results together, and you get twelve.

11 + 1 = 12
