What is the value of x in the equation shown below.

0.25x + 7 = 4(x - 2)​

Answers

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.

Maplewood Supply received a $5,270 invoice dated 4/15/10. The $5,270 included $270 freight. Terms were 3/10, 2/30, n/60.
a. If Maplewood pays the invoice on April 27, what will it pay?
b. If Maplewood pays the invoice on May 21, what will it pay?

Answers

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)

Answers

Answer:

y= -3yx + 9x - 37

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

The proportion is [tex]\frac{35}{108}[/tex] = [tex]\frac{x}{84}[/tex], and the length of the unknown side is [tex]\frac{245}{9}[/tex] or 27.22 approximately rounded to the nearest hundredth.

Step-by-step explanation:

Since the triangles are similar, the proportion of corresponding sides are equal. The pairs of corresponding sides in these triangles which we'll use to solve it are LK, KE, MK, and KF. LK and KE are corresponding sides, and their proportion is [tex]\frac{35}{108}[/tex]. MK and KF are corresponding sides, and their proportion is [tex]\frac{x}{84}[/tex] in which x represents the missing side. The proportions are equal, so [tex]\frac{35}{108}[/tex] = [tex]\frac{x}{84}[/tex]. Multiply both sides by 84 to isolate the variable, and you'll get [tex]x = \frac{35*84}{108}[/tex], which is [tex]\frac{2940}{108}[/tex] or [tex]\frac{245}{9}[/tex].

An equilateral triangle has a height of 6 centimeters. What is the exact length of one of the sides of the triangle?

4 cm

O 23 cm

O 2 cm

O 473 cm

Answers

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.

What is equilateral triangle?

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.

An article describes the chemical compositions of certain minerals in the early Archaean mantle. For a certain type of olivine assembly, the silicon dioxide (SiO2) content (in weight percent) in a randomly chosen rock has mean 40.35 and standard deviation 0.4. Find the mean and standard deviation of the sample mean SiO2 content in a random sample of 10 rocks. Round the mean to two decimal places. Mean Standard deviation

Answers

Answer:

The mean is 40.35 and the standard deviation is 0.13.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a certain type of olivine assembly, the silicon dioxide (SiO2) content (in weight percent) in a randomly chosen rock has mean 40.35 and standard deviation 0.4.

Sample of 10:

By the Central Limit Theorem, the mean is 40.35, and the standard deviation is [tex]s = \frac{\sigma}{\sqrt{n}} = \frac{0.4}{\sqrt{10}} = 0.13[/tex]

The mean is 40.35 and the standard deviation is 0.13.
