Triangle ABC, shown in the diagram below, is an isosceles triangle


If the measure of <ABC is 42.5°, what is the measure of <ABC?​

Answer:

1.57142857

Step-by-step explanation:

Answer:

a = 3

Step-by-step explanation:

AB/AC = 7/8 = 14a/48

7/8 = 14a/48

Multiply both sides by 8.

7 = 14a/6

Multiply both sides by 6 and switch sides.

14a = 42

a = 3

Answer:

25 feet by 4 feet

Step-by-step explanation:

Answer:

This shape is an irregular polygon. This means we have to find the area of the whole shape and then subtract the missing parts to get the correct answer.

First, we have to find the area of the whole shape (a rectangle). The formula for a rectangle's area is:

The length of the shape is 19 ft, and the width is 29 ft. Now, we apply the formula to those numbers:

Now that we know that the area of the whole polygon is 551 square feet, we have to find the area of:

1. The first missing triangle

2. The second missing triangle

3. The missing rectangle

Add all of those areas together, and then subtract them from 551 and we have the answer.

First, we find the area of the missing triangle in the top left hand corner. The area formula for a triangle is

So, we have to find the base and the height. We see that part of the whole polygon's width is 4 ft, which is not missing, so we subtract that from the total width, 19 ft.

This means that the triangle's base is 15 ft. Now, we have to find the height. We can easily see that the height is 15 ft, as it says so in the picture.

Now, we just have to apply the formula:

So, we have our first area, 112 square feet.

Now we have to find the area of the second missing triangle in the bottom right corner.

We know that the base is 4 ft, as it says so in the picture. The height is 24 ft. We know that the total height of the polygon is 29 ft, and we see a shaded part of 25 ft in height. So:

According to this equation, we have 4 ft in height. Using the area formula for triangles, here is our equation:

This equation states that our second area is 8 square feet.

Now, we just have our last area to find, the missing rectangle. According to all of the previous information, and the picture, we see that the width is 15 ft and the height is 14 ft. Now we apply the area formula for rectangles:

Lastly we add up all of our areas: 112.5 square feet, 8 square feet, and 210 square feet.

Then, we subtract 330.5 from 551:

​​The answer is 220.5

Answer:

30 hens, 20 cows.

Step-by-step explanation:

Step one:

let the number of cows be x

and the number of hens be y

Each cow has 2 eyes, each hen has 2 eyes also.

the total number of eyes is

2x+2y

Each cow has 4 legs, each hen has 2 legs.

the total number of legs is

4x + 2y

Step two:

the number of legs exceeds the number of eyes by 40:  

4x+2y - (2x+2y) = 40

open bracket

4x+2y-2x-2y=40

4x-2x=40

2x=40

Divide both sides by 2

x=40/2

x=20

Step three:

we know also that x = 2/3*y, so y = 3/2*x = 3/2 * 20 = 30

30 hens, 20 cows.

Check:

60 + 40 eyes = 100, 60 + 80 legs = 140legs.

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

First, we need to convert 2 2/3 hours to minutes. This would be:

= 2 2/3 × 60 minutes

= 8/3 × 60 minutes

= 160 minutes

Since water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. The the gallons of water going over the waterfall in 2 2/3 hours would be:

= (162 1/2 × 2 2/3hours) / 15 minutes

= (162 1/2 × 160) / 15

= 1733 1/3 gallon

Thanks dude

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=\sqrt{x^3-16x}[/tex]

We know that the domain of the function is the set of input or arguments for which the function is real and defined.  

In other words,  

Now, determine non-negative values for radicals so that we can sort out the domain values for which the function can be defined.

[tex]x^3-16x\ge 0[/tex]

as x³ - 16x ≥ 0

[tex]\left(x+4\right)\left(x-4\right)\ge \:0[/tex]

Thus, identifying the intervals:

[tex]-4\le \:x\le \:0\quad \mathrm{or}\quad \:x\ge \:4[/tex]

Thus,

The domain of the function f(x) is:

[tex]x\left(x+4\right)\left(x-4\right)\ge \:0\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-4\le \:x\le \:0\quad \mathrm{or}\quad \:x\ge \:4\:\\ \:\mathrm{Interval\:Notation:}&\:\left[-4,\:0\right]\cup \:[4,\:\infty \:)\end{bmatrix}[/tex]

And the Least Value of the domain is -4.

Step-by-step explanation:

Answer: =1.34

Step-by-step explanation:

In standard density curve

P(Z<z) = Area left of z, P(Z>z) = area right of z.

P(Z<z) +P(Z>z) =1

Given:  z is a standard normal random variable.

To find : value of z if rea to the right of z is 0.01.

i.e. P(Z>z) =0.01

P(Z<z) =1-0.01 = 0.09

from z-score table, z value for this is 1.34.

Hence, z= 1.34

Answer:

300,000

Step-by-step explanation:

3 ten thousands = 30,000

30,000 * 10 = 300,000

Hope this helps :)

10 times as much as 3 ten thousand is equal to 300,000.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the number is 10 times as much as 3 ten thousand. The number will be calculated as below:-

3 ten thousands = 30,000

30,000 x  10 = 300,000

Therefore, 10 times as much as 3 ten thousand is equal to 300,000.
