Answer:

[tex]2\sqrt{34}[/tex]

Step-by-step explanation:

We can add a line to create a triangle and a rectangle. The triangle will have side lengths 10 and 6. Furthermore, it will be a right triangle, meaning we can apply the Pythagorean Theorem to find x, the hypotenuse.

[tex]6^2 + 10^2 = x^2\\x = \sqrt{6^2 + 10^2}\\ = \sqrt{136} \\= 2\sqrt34}[/tex]

Step-by-step explanation:

Remark

When a quadrilateral is inscribed in a circle, the opposite angles are supplementary. x is opposite 112 degrees. Therefore x and 112 add up to 180 degrees.

Formula

x + 112 = 180                      Subtract 112 from both sides.

Solution

x + 112-112 = 180 - 112

x = 68

Answer

x = 68

Answer:

Step-by-step explanation:

#9.

x° = 200° and x = 200

y° = 100° and y = 100

#10.

x° = 68° , x = 68

y° = 99° , y = 99

   The angle of elevation is the angle of which something, in simple terms, is raised from a straight plane. If it is the angle downwards, we call this the angle of depression.

Answer:

1. x=37

2. x= 50

Step-by-step explanation:

Add up the two angles you already have, 43+100 and then subtract from 180.

180-143= 37

Do the same thing for number 2.

Add up 99+31, which is 130

The subtract from 180

180-130=50

The equation for triangles is x + (the angle measures) = 180

Using the normal distribution, it is found that the life span of an appliance that has a z-score of –3 is of 24 months.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the parameters are given as follows:

[tex]\mu = 48, \sigma = 8, Z = -3[/tex].

Hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-3 = \frac{X - 48}{8}[/tex]

X - 48 = -24

X = 24.

The life span of an appliance that has a z-score of –3 is of 24 months.

Answer:

Using the normal distribution, it is found that the life span of an appliance that has a z-score of –3 is of 24 months.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean  and standard deviation  is given by:

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, the parameters are given as follows:

.

Hence:

X - 48 = -24

X = 24.

The life span of an appliance that has a z-score of –3 is of 24 months.

1/3 * 420 = amount of t-shirts sold in the morning

1/3 * 420 = 420/3 = 140 t-shirts

140 t-shirts were sold, so remaining is 420 - 140

420 - 140 = 280 remaining t-shirts

4/7 * 280 = amount of t-shirts sold in the afternoon

4/7 * 280 = (280/7) * 4 = 40 * 4 = 160 t-shirts

160 t-shirts were sold, so remaining is 280 - 160

the remaining t-shirts = 120 t-shirts

120 t-shirts are left to sell at the end of the day

The volume of the cylinder will be equal to V=1885 cubic cm.

The Volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The cylinder is the right circular object with some height like bamboo, bottles, rods etc all are cylinders.

The formula for calculating the volume of the cylinder is given as:-

V=πr²H

Here we have the radius of the cylinder r= 10 cm and the height of the cylinder is H=6 cm

V=  π x (10)² x  6

V=1885 cubic cm.

Hence the volume of the cylinder will be equal to V=1885 cubic cm.

Step-by-step explanation:

So whenever you see alphabets in math, these are called variable. Like the word suggests, variables can have different values depending on the problem.

For the first problem, the variable k equals 10, and the question asks you when k=10, what does that make k+26. All you do is substitute the value of k with the given value of k=10, and you get 10 + 26 = 36.

This way you can solve the rest of them.

FIFO means "first in - first out". so, it is airways the oldest in the inventory that is sold. that means the newest or youngest items in the inventory remain.

the end inventory shows 70 units.

that means, all the November units (64) plus 6 of June are still there.

a.

the cost of the ending inventory is

576 + 6×8 = 576 + 48 = $624

the cost of goods sold is then

1727 - 624 = $1,103

control :

196 + 483 + (59-6)×8 = 679 + 53×8 = 679 + 424 =
