Find the diagonale of the base.

Answers

Answer: 8.94

Step-by-step explanation:

By common logic, you can say that l=8, w=4 and h=2.

The diagonal of the base can be found by using Pythagorean Theorem.

Pythagorean Theorem: a²+b²=c²

Since we know the a and b of the base, we can find c, the diagonal.

a and b is the l and w. We can use the equation to find c.

8²+4²=c²

64+16=c²

80=c²

c=√80

c≈8.94

The diagonal is approximately 8.94

What is the slope of a line that is perpendicular to the line whose equation is 2y = 3x - 1? -3 - -

Answers

Answer: 2/3x

Step-by-step explanation:

First, you need to simplify your original line to point slope formula. Dividing the whole thing by 2 to get y by itself leaves you with

y = 3/2x - 1/2

Any perpendicular line has the opposite slope to the line it is perpendicular to, so you flip the slope to get 2/3x

A swimming pool is 22 feet long and 18 feet wide. How many feet of fencing are needed to enclose the pool

Answers

Answer:

80 feet

Step-by-step explanation:

length of pool = 22    ,  width of pool = 18

feet required for fencing the pool = 2 (l +b)

= 2 ( 22+18)

=2*40

=80feet

Answer:

Step-by-step explanation:

The pool is a rectangle as length and breadth are different.

Since they are asking about fencing you need to find the perimeter.

Length=22feet

Breadth=18feet

Perimeter of a rectangle = 2(l+b)

= 2 × 22 + 2×18

=44+36

=80 feet

V = IR
What is I equal to?​

Answers

Answer:

I=V/R

Step-by-step explanation:

In this equation, we see that there are no numerical values so we can't exactly solve for the exact number. Because of this, all you do Is isolate the variable "I" by itself. To do this, divide R on both sides. This way, you isolate I and on the other side you get V/R that cannot be further simplified.

Answer:

I=V/R

Step-by-step explanation:

V=IR

Divide both sides by R to isolate I

V/R=I

Kostya randomly chooses a number from 1 to 10. What is the probability he chooses a number less than 5?

A. 1/2
B. 4/9
C. 2/5
D. 3/5​

Answers

Answer:

Step-by-step explanation:

2/5

If Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability Kostya chooses a number less than 5.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given that Kostya randomly chooses a number from 1 to 10.

We have to find the  probability he chooses a number less than 5

There are four numbers that are less than 5 .

The numbers less than 5 are 1, 2, 3, 4.

The probability that Kostya randomly chooses one of these numbers is 4/10,

Divide numerator and denominator by 2

We get 2/5

Hence, if Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability he chooses a number less than 5.

If the sum of the squares of nonnegative real numbers a,b, and c is 39, and ab + bc + ca = 21, then what is the sum of a,b, and c?

Answers

Answer:

Step-by-step explanation:

a² + b² + c² = 39

ab + bc + ca = 21

(a + b + c)² = a² + b² +c² + 2[ab + bc +ca]

(a + b + c)² = 39 + 2*21

                 = 39 + 42

(a+ b + c)² = 81

a +b + c = √81 = √9*9

a + b + c = 9

Answer:

Contributions to an IRA

Step-by-step explanation:

A P E X

All options could change a taxpayer's adjusted gross income when filing a federal income tax return.

Options A, B, C, and D are the correct answers.

What is taxpayer-adjusted gross income?

Taxpayer-adjusted gross income (AGI) is a person's gross income (all income from various sources such as wages, self-employment, interest, dividends, and capital gains) minus certain deductions (such as contributions to a traditional IRA, alimony payments, and student loan interest).

We have,

- Medical and dental expenses are deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.

- Contributions to an IRA may be deductible, which would lower the taxpayer's adjusted gross income.

- Casualty and theft losses may be deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.

- Charitable contributions made are deductible if the taxpayer itemizes deductions, which would lower the taxpayer's adjusted gross income.

Thus,

All of the above could change a taxpayer's adjusted gross income when filing a federal income tax return.

Can someone help me find the slope , y-intercept ,and equation pls help it’s my finals

Answers

Answer:

slope: -3

y-intercept: -5

equation: y = -3x - 5

Step-by-step explanation:

The formula for slope is:

(y2 - y1)/(x2 - x1)

Let's use these coordinates:

(-1, -2)

(0, -5)

x1 = -1

x2 = 0

y1 = -2

y2 = -5

Substitute into the formula:

(y2 - y1)/(x2 - x1)

(-5 + 2)/(0 + 1)

Solve:

(-5 + 2)/(0 + 1)

-3/1

= -3

slope = -3

The y-intercept is when the x coordinate is 0.

Looking at the table, we see the coordinate (0, -5).

The y-coordinate is -5.

This means that the y-intercept is -5

y-intercept = -5

Slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept

m = -3

b = -5

Substitute:

y = mx + b

y = -3x - 5
