43 = 4 tens and 3 ones. (:

10 + 10 + 10 + 10 = 40

1 + 1 + 1 = 3

40 + 3 = 43

use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number.

Jobisdone [24]

Answer:

Second Option

671 m²; 725 m²

Step-by-step explanation:

The lateral area of a triangular prism is:

$A_L = Ph$

Where P is the perimeter of the triangular base and h is the height of the prism.

In this case, the perimeter of the triangular base is:

$P = 9 + 6+ 10.82\\\\P = 25.82\ m$

Then the height is 26 m

Then the lateral area of the prism is:

$A_L = 25.82 * (26)\\\\A_L = 671\ m ^ 2$

Therefore the surface area of the triangular prism is:

$A = 2A_B + A_L$

Where $A_B$ is the area of the base.

$A_B = \frac{bh}{2}$

Where b is the base of the triangle and h is the height

In this case:

$b = 9\ m\\\\h = 6\ m\\\\A_B = \frac{9 * 6}{2}\\\\A_B = 27\ m ^ 2$

Finally

$A = 2 * 27 + 671\\\\A = 54 + 671\\\\A = 725\ m ^ 2$

The answer is 671 m² and 725 m²

The first number is eight more than the second one. Three times the second number plus twice the first number is equal to 26. Fi

aliina [53]

Let us consider the second number would be $"x"$

The first number is eight more than the second one.

That is, the first number would be $"x+8"$

Three times the second number would be $"3x"$

Twice the first number would be $"2(x+8)"$

Now write the statement in mathematical form: "Three times the second number plus twice the first number is equal to 26"

$3x+2(x+8)= 26$

Solve this equation for x:

Distribute 2 in $x+8$ , we get

$3x+2x+16=26$

Combine the like terms,

$5x+16=26$

Subtracting 16 on both sides,

$5x+16-16=26-16$

$5x=10$

Dividing 5 on both sides,

$x=10/5=2$

So the second number is $x=2.$

Now find the first number:

First number $= x+8=2+8=10.$

Thus the numbers are 10 and 2.

Express the alternative hypothesis in symbolic form. An automobile technician claims that the mean amount of time (in hours) pe

muminat

Answer:

$H_{0}$ : mu1-mu2=0

$H_{a}$ : mu1-mu2>0

Step-by-step explanation:

Let mu1 be the mean amount of time (in hours) per domestic car repair

and mu2 be the mean amount of time (in hours) per foreign car repair

According to the claim of the automobile technician, the mean amount of time (in hours) per domestic car repair is more than that of foreign cars.

Then null and alternative hypotheses can be stated in symbolic form as

$H_{0}$ : mu1-mu2=0

$H_{a}$ : mu1-mu2>0

What’s The definition of linear and nonlinear in Math

Helga [31]

Answer:

Functions can be classified in two different categories: linear or nonlinear. A simple way to know differentiate between the two is to look at the output values when plugging in a number for an unknown variable. If the output values have a difference that is constant, then the function will be classified as a linear equation; however, if the outputs do not have a constant difference then it will be classified as a nonlinear equation.

Another easy way to determine which of these functions you are dealing with is to graph it. By graphing these functions, you can tell if the line is straight or not. When graphed, a linear equation will have a straight line that has a constant slope. In contrast to this, a nonlinear equation will have a graph that does not have a straight line and, depending on the function, can have many different appearances including a U-shape or an S-shape.
