If I get a 100 on one assingment and a 57 on the other, what is my average of the assignments?

Answer:

-2.6

Step-by-step explanation:

Given: 5(y+2)= -3

Do the parentheses (Multiply 5 by Y and 2): 5y+10=-3

Simplify (subtract 10 from both sides): 5y=-13

Simplify again (divide both sides by 5): y=-2.6

Double-Check:

Given (replace -2.6 for Y): 5(-2.6+2)=-3

Do the parentheses (Add-2.6 and 2): 5(-0.6)=-3

Simplify (Multiply 5 by -0.6): -3=-3 ✔️

The answer checks out.

Step-by-step explanation:

[tex]\text{Area of the trapezoid}= \left(\dfrac{AD+BC}2\right)CK\\\\\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\left( \dfrac{10+8}2\right) \times 30 \\\\\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\dfrac{18}2 \times 30\\\\\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=9 \times 30\\\\\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=270~~ \text{sq units.}[/tex]

Answer:

136

Step-by-step explanation:

Area of trapezoid:

a+b/2 * h

so,

(12/2 + 22/2) × 8

12 + 22 = 34

34/2 = 17

17 × 8 = 136

The function f(x) is a sine graph, and the function with the greatest maximum range value is the function f(x)

From the complete question (see attachment), the functions are given as:

Functions f(x) and g(x)

The maximum range value of these functions is their maximum output value

Function f(x) has a maximum range value of 3, while function g(x) has a maximum range value of -2

3 is greater than -2

Hence, the function with the greatest maximum range value is the function f(x)

Answer:

pi or 3.14

Step-by-step explanation:

this shape is a quarter of a circle.

so, we can just find the area of the whole circle and then divide the answer by 4.

to find the area of this shape we use the formula:

pi × r^2 × 1/4

so the answer is: pi since r^2 and 1/4 cancel each other out.

Finding the Missing Angle Within the Triangle

We know that all triangles sum to 180 degrees. So, to find the missing angle within the missing angle, we can create an equation. For the purposes of this equation, I will use y as the missing angle within the triangle.

Then, solve for y by subtracting 55 and 68 from both sides.

Finding X

The missing angle within the triangle is supplementary to the x angle. Supplementary angles are angles that sum to 180. So, to find x we can create a new equation.

Next, solve the formula by subtracting 57 from both sides.

Shortcut

In cases like this, there is a shortcut that can be used. This shortcut can be used when you are trying to find a supplementary angle outside of a triangle, and you are given the other 2 angles of triangle. The x value will always be equal to the sum of the 2 angles that are not adjacent to the missing, outside angle.

So, in this case, [tex]x=68+55[/tex] because 68 and 55 are not adjacent to the outside angle, x.

26.77 mph

Step-by-step explanation:

Formula for Avg. Speed = Distance/Time

80.31/3 = 26.77

Answer:

26.77 miles per hour

Step-by-step explanation:

Distance ÷Time

80.31 miles ÷3hrs

= 26.77 miles per hour

The measure of the angle BAC is 72degrees

We have given that the

angle B=108 degrees and angle C=60 degrees.

We have to determine angle A

In parallelogram

The sum of the two angles is 180 degrees.

Therefore we get,

angle A+ angle B=180 degrees

angle B=108 degrees

angle A +108=180

angleA=180-108

angleA=72 degrees.

Therefore the measure of the angle A is 72degrees

Answer:

294.1 pounds

Step-by-step explanation:

We find the z score for 90th percentile

= 1.282

Step 2

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score ??

μ is the population mean = 230 pounds

σ is the population standard deviation= 50 pounds

1.282 = x - 230/50

Cross Multiply

1.282 × 50 = x - 230

64.1 = x - 230

x = 230 + 64.1

x = 294.1 pounds

Answer:

1716

Step-by-step explanation:

The first choice would be 1 of 13
The second choice would be 1 of 12 (it can't be the same as the first number since they don't repeat)
The third choice would be 1 of 11 (again, can't use the same number more than once)

That gives you 13*12*11=1716

The number of ways we can choose three different numbers in order for a unique code for this case is 2730.

In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.

here, we have,

We can use combinations for this case,

Total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total of mCk ways.

If the order matters, then each of those choice of k distinct items would be permuted k! times.

So, total number of choices in that case would be:

mPk = m! / (m - k)!

This is called permutation of k items chosen out of m items (all distinct).

Given that:

The considered lock as a 3 number code

There are 15 numbers available.

None of the number can repeat.

In a lock, the order of the way numbers are arranged matters.

Because of no repetition allowed, we can simulate this situation as:

The number of ways we can choose 3 numbers out of 15 numbers with order = The number of different ways we can choose three different numbers in order for a unique code.

And we have:

The number of ways we can choose 3 numbers out of 15 numbers with order = 15P3 = 2730

Thus, the number of ways we can choose three different numbers in order for a unique code for this case is 2730
