Find the value of x. (4x + 12)° 64°​

Find The Value Of X. (4x + 12) 64

Answers

Answer 1

Answer:

C. 13

Step-by-step explanation:

the angle of measure 4x + 12 and the angle of measure 64 are Vertically opposite angles then they are equal in measure

therefore

4x + 12 = 64

⇔ 4x = 64 - 12

⇔ 4x = 52

⇔ x = 52/4

⇔ x = 13

Answers

Answer:

It is negative.

Step-by-step explanation:

-6 - 65 is -71

Hope that helps!

Answer:

negative

Step-by-step explanation:

The equation -6 - 65 equals -71 because 65 is a positive number and -6 is not which means it must keep going negative because a negative plus a positive goes negative.

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. which statement describes the situation modeled by this system? startlayout enlarged left-brace 1st row h = 35 minus 16 t squared 2nd row h = 6 18 t 16 t squared endlayout the height of the baseball is 18 feet at the moment the player begins to leap. the height of the baseball is 16 feet at the moment the player begins to leap. the height of the baseball is 35 feet at the moment the player begins to leap. the height of the baseball is 6 feet at the moment the player begins to leap.

Answers

The height of the baseball is 6 feet at the moment the player begins to leap. Then the correct option is D.

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.

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.

Answers

Simply add the two equations up to get (-2x+y)+(5x-y)=8-5
Simplify to get 3x=3

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

therefore, x =1

Answer:

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.

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

-- 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

Solve for x in the triangle. Round your answer to the nearest tenth. (Please help)

Answers

Answer:

x = 6.5

Step-by-step explanation:

Since this is a right triangle we can use trig functions

cos theta = adjacent side / hypotenuse

x cos 23 / 6

x = 6 /cos 23

x=6.51816

x = 6.5

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°

So

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

So

<EHF=2(66)=132°
