Based on your value of x in question #1, what is the value for ∠EHF
1) 132 degrees
2) 96 degrees
3) 180 degrees
4) 90 degrees

Answers

Answer:

∠EHF = 132°

Step-by-step explanation:

Both angles lie on a straight line.

=====================

∠EHF + ∠FHG = 180°2(x) + 48° = 180°2(x) = 180° - 48°2(x) = 132°x = 66°

Then ∠EHF :

2(x)2(66)132°

Angles are supplementary hence their sum is 180°

2x+48=1802x=180-482x=132x=66

<EHF=2(66)=132°

i need help finding our the perimeter

Answers

Answer:

11x + 10y - 2w

Step-by-step explanation:

Hello!

To solve for the perimeter, we add up the like terms.

What are like terms?

Like terms are terms with the same variable and degree. 4x and 5y are NOT like terms because the variable is not the same. However, 4x and 3x are like terms, as adding them gives us 7x.

4x and 4x² are not like terms, because the degree of 4x is 1 (degree means the largest exponent), but the degree of 4x² is 2.

Solve for Perimeter:

Combine the like terms by adding them up.

Perimeter = (8x - 4w) + (3y + 2w) + (3x + 7y)P = 8x - 4w + 3y + 2w + 3x + 7yP = 8x + 3x + 3y + 7y - 4w + 2wP = 11x + 10y - 2w

The perimeter is 11x + 10y - 2w

If 30% of the 1000 cars on a lot are not hybrids, and 45% are not sedans, how many cars on the lot are hybrid sedans?

Answers

The number of cars that are hybrid sedans are = 250 cars

Calculation using a Venn diagram

The value of 30% of 1000 = 30/100× 1000

= 300 cars are not hybrids.

Therefore the number of cars that are hybrids = 300 - x

The value of 45% of 1000 = 45/100 × 1000

= 450 cars are not sedans

Therefore the number of cars that are sedans

= 450 - x

Where X is the cars that are both hybrid and sedans

Using the Venn diagram equation,

1000 = 300 -x + X + 450 - x

1000 = 750 - X

X= 750 - 1000

X = 250 cars

The number of cars that are hybrid is 300 - x where X = 250.

300 - 250 = 50 cars

The number of cars that are sedans is 450 - x. That is,

450 - 250 = 200 cars

Therefore, the cars that are both hybrid and sedans = 250 cars.

If you're rolling a single cube, then ...

-- There are 6 possible out comes.

-- One of them (5) is a multiple of 5 .

-- The probability of rolling it is (1/6) = 16-2/3 % .

If everything is acting perfectly random, then ion 100 rolls,

you'd expect to succeed 16 or 17 times.

If you're rolling a pair of cubes, then ...

-- There are (6 x 6) = 36 possible outcomes.

-- There are seven ways to get a multiple of 5.

(1+4), (4+1), (2+3), (3+2), (4+6), (6+4), (5+5)

-- The probability of rolling one of those is

(7/36) = 19-4/9 % .

x < -10

Step-by-step explanation:

Solve the inequality.

-2x + 4 > 24 Subtract 4 from both sides

-2x > 20 Divide both sides by -2

x < -10 We must flip the inequality sign because we divided by a negative number in the last step.

When you graph, draw a number line. Then, draw a circle on top of -10. Since x is less than -10, the arrow goes to the left of -10. Additionally, the circle on top of -10 will be an open circle because the inequality sign is a less than, not a less than or equal to.

Simply add the two equations up to get (-2x+y)+(5x-y)=8-5

Answer:

3x = 3

Step-by-step explanation:

the right answer is 3x = 3

-2x + y = 8 .......(i)

5x-y =-5........(ii)

From equation (i)

y=8+2x

Putting the value of y in euation (ii)

We have,

5x-(8+2x) = -5

5x-8-2x = -5

3x=-5+8

3x = 3

also what we can do is,

x=3/3

What is a function?

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The first equation in the system models the height in feet, h, of a falling baseball as a function of time, t. the second equation models the height in feet, h, of the glove of a player leaping up to catch the ball as a function of time, t.

h(t) = 35 - 16t²

h(t) = 6 + 18t + 16t²

At t = 0, Then we have

h(0) = 35 - 16(0)²

h(0) = 35

And

h(0) = 6 + 18(0) + 16(0)²

h(0) = 6

The height of the baseball is 6 feet at the moment the player begins to leap.
