Answer:

24 meters

Step-by-step explanation:

Alright. Your question had errors, but I managed to scramble together some answers.

The right triangle has a total of 3 sides, 2 which are 8 and 6. We need to find the hypotenuse.

Let's use the Pythagorean Theorum.

a^2 + b^2 = c^2

8^2 + 6^2 = c^2

64 + 36 = 100

To get c by itself, square root it.

[tex]\sqrt{100} =10[/tex]

You found the hypotenuse :D

Add it up!

8 + 6 + 10 = 24 meters

Answer:

Remember this formula.

Step-by-step explanation:

[tex]\sqrt{a^{2}+b^{2}=c^{2}[/tex]

If your legs are 8 and 6, the last side is the hypotenuse, which is always the largest side of a right triangle. You calculate it's length by taking the measurements of leg A and leg B, and squaring both of them, or raising them both by the power of 2.

This will equal C, or your hypotenuse, but it will be squared, so you have to find its square root to get the actual measurement, which is why the equation has a square root sign over it, so the answer is automatically squared when put into a calculator.

8 x 8 = 64 [or [tex]8^{2}[/tex]]

6 x 6 = 36 [or [tex]6^{2}[/tex]]

[tex]8^{2}+6^{2}=100\\\sqrt{100}=10[/tex]

[tex]\sqrt{8^{2}+6^{2}=10[/tex]

answer:

option A y≤3x

The system of equations that matches the graph is as follows:

y ≤ 3x

y > -2x - 1

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The line y = 3x represents the boundary for the first inequality, and the line y = -2x - 1 represents the boundary for the second inequality.

The first inequality has a less than or equal to sign, the region below the line y = 3x is shaded.

The second inequality has a greater than sign, the region above the line y = -2x - 1 is shaded.

The overlapping region of the two shaded regions represents the solution to the system of inequalities, which is the region where both inequalities are true. Therefore, the solution is the triangle-shaped region that is below the line y = 3x and above the line y = -2x - 1.

The shaded region represents the solution to the system of inequalities y ≤ 3x and y > -2x - 1.

Answer:

55

Step-by-step explanation:

Since this is an isosceles triangle, the angles at the bases of the identical legs must be equal

<A = <C

3x+40 =x+50

Subtract x from each side

3x-x+40 = x+50-x

2x +40 = 50

Subtract 40 from each side

2x+40-40=50-40

2x = 10

Divide each side by 2

2x/2=10/2

x = 5

We want to find <A

3x+40

3(5)+40

15+40

Answer: 11,682.4 miles

Step-by-step explanation:

We can think the planet as a circle:

if we have a circle of radius R, and an arc of A degrees in the circle, the lenght of the arc is:

L = (A/180°)*3.14*R

Here we know that:

L = 4076 miles

A = 20°

Then:

4076mi = (20/180)*3.14*R = 0.3489*R

R = 4076mi/0.3489 = 11,682.4 miles

Answer:

6 cube/to the 3rd units

Step-by-step explanation:

um idk if this is what you want but yeah

if you spilt it into a 2x2x1 and a 1x2x1 you can count that there are 6 cube units

Answer:6 cubes

Step-by-step explanation:

There are 2 ways that I think you could solve this.

1. First, you could make those 2 missing cubes actual cubes, so then you could find the volume of the cube by doing 2x2x2(length x width x height) and you would get 8 cubes. After that, you would take away the two missing cubes, and you would get 6 cubes.

2. You could also just count the cubes. I counted the two inner cubes and then counted the 4 outer cubes, and got 6 cubes.

Hope this helps!

Answer:

P = 40.56 in (ANS)

Step-by-step explanation:

radius = 8/2 = 4 in

semi-circle perimeter = pi * R = 3.14 * 4 = 12.56 in

figure perimeter = 12.56 + 10 + 8 + 10 = 40.56 in (ANS)

Step-by-step explanation:

Answer:

The correct inequality is: b< -6 or b > 6

Step-by-step explanation:

The absolute value operator always results in a positive number, in such a way that if b > 0, then |b| = b, while if  b < 0, then |b| = -b. With this in mind, let's look at the inequality given:

|b| > 6

This will be true for values of b that are greater than 6 and values of b that are less than -6, due to the absolute value operator. Therefore the compound inequality that represents this situation is:

b< -6 or b > 6

Answer:

I think it is D (and)

Step-by-step explanation:

"Or" means that the b value can be less than -6 or greater than 6

so it could satisfy either one

so if you plug in a value that satifies one of the inequalities (ex: -7)

|-7|>6  and it works!

Answer:

Step-by-step explanation:

a) Total number of people surveyed, n = 2500

Let X denote the number in the sample that say they support the increase. If 30% of all adults in Ohio support the increase, it means that the percentage of all adults in Ohio that did not support the increase is

100 - 30 = 70%

This is a binomial probability because there are only two possible outcomes. Therefore,

Probability of success, p = 30/100 = 0.3

Probability of failure, q = 1 - p = 1 - 0.3

q = 0.7

Standard deviation = √npq

Standard deviation = √(2500 × 0.3 × 0.7) = 22.91

b) The probability that x is at least 800 is expressed as

P(x ≥ 800)

We would determine the probability by using the binomial probability calculator. Therefore,

P(x ≥ 800) = 0.01577

b. about 0.015.

Answer:

13.4lbs

Step-by-step explanation:

10.2/52 = 0.2lbs per inch

0.2(67) = 13.4lbs

Using unitary method, the weight of a 67 inch steel bar is 13.4 lbs.

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Weight of 52 inch flat steel bar = 10.4 lbs.

Weight of 1 inch flat steel bar = 10.4/52 = 0.2 lbs.

Weight of 67 inch flat steel bar = 0.2 * 67 = 13.4 lbs.

Answer:

$1,875

Step-by-step explanation:

$15.00 per hour (multiply by hours)

per technician (multiply by technicians)

so: 15x25=375 then 375x5=1,875

Answer:

$1875

Step-by-step explanation:

First, let's find how many hours the technicians worked

She has 5 technicians, and the each worked 25 hours

We can multiply 5 and 25 to find the total number of hours

5*25=125

Now we know that the technicians worked 125 hours altogether. Now, we need to find how much money that is.

They worked 125 hours, and they are paid $15 per hour

We can multiply 125 and 15 to find the cost

125*15=1875

So, Dr. Barber will pay the technicians $1875 in total

Answer:

Between 10 and 11.

Step-by-step explanation:

To begin, we can look at the problem as such. If we take the first answer choice, we can find the squares of both numbers giving us: (Remember that the area of a square is A=L²)

10²= 100

11²= 121

Since the given area is in between these two numbers, this means that the side length must be between 10 and 11.

Answer:

37.5

Step-by-step explanation:

If you cut 600 in half 4 times the first time it will be 300 because 600/2 is 300. The second time it will be 150 because 300/2 is 150. The third time it will be 75 because 150/2 is 75. The fourth time it will be 37.5 because 75/2 is 37.5, so that is the answer.
