Answer:

88

Step-by-step explanation:

46= x° ( isosceles angles )

Now, taking all side of the triangle

46+46+y =180 ( sum of all side of triangle )

or, y= 180 -92

y = 88°

Answer:

14

Answer:

t = 5 s

Step-by-step explanation:

The function that gives the height in feet of the ball t seconds after it is thrown is :

[tex]h(t)=-16t^2+48t+160[/tex]

We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.

So,

[tex]-16t^2+48t+160=0[/tex]

We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.

t = -2 s is not possible.

Hence, the ball will hit the ground before 5 seconds.

Answer:

y = 62

Step-by-step explanation:

Since we need to solve for x first, we'll solve the left triangle first. A triangle equals 180 degrees, so with in mind:

x + 7 + 3x - 18 + x - 9 = 180

add like terms

5x - 20 = 180

add 20 to both sides

5x = 200

divide by 5

x = 40

Now we have x, input it into the equations for the second triangles:

x + 21 + x + 17 + y = 180

40 + 21 + 40 + 17 + y = 180

add/simplify

118 + y = 180

subtract 118 from both sides

y = 62

Answer:

x = 40° ; y = 62°

Step-by-step explanation:

The figure consists of 2 triangles. According to Angle sum property in a triangle , sum of measure of all the angles of a traingle is equal to 180° .

So ,

[tex](3x - 18) + (x + 7) + (x - 9) = 180[/tex]

[tex] = > 5x - 20 = 180[/tex]

[tex] = > 5x = 180 + 20 = 200[/tex]

[tex] = > x = \frac{200}{5} = 40[/tex]

Now using the angle sum property in another triangle ,

[tex](x + 21) + (x + 17) + y = 180[/tex]

[tex] = > y + (40 + 21) + (40 + 17) = 180[/tex]

[tex] = > y + 61 + 57 = 180[/tex]

[tex] = > y + 118 = 180[/tex]

[tex] = > y = 180 - 118 = 62[/tex]

here is what i found also you could of looked it up

Step-by-step explanation:

(x,y)→(x+4,y)

Answer:

you can set up a proportion

16.0/130  = x/2150

by cross multiplying you get

130x = 34400

divide by 130 and get

x-264.62

Answer:

it got to be b the 4 is on the line 3 so be -3 and 4 postive

Answer:

54

Step-by-step explanation:

it's so easy just do

18÷1/3=54 which is easir if you think it like 18×3=54

Answer:

54

Step-by-step explanation:

For every liter of sports drink, there is 3 players. You can use this problem to solve it y = 3x  or now  54 = 3(18). Simply it is 3 * 18 is 54. 3 is from 3 people per liter.

Answer:

The answer would be the last option. y<2/3x-1

Step-by-step explanation:

The slope is 2/3 and the line crosses the y axis at -1. Since the shaded part is below the line it would make the sign less than (<)

Answer:

I think the answer is ummm, 32? if its wrong then i'm sorry, i hope this helps, have a great day/night, and stay safe!

Answer:

Step-by-step explanation:

Answer:

153/50 or 3.06

Step-by-step explanation:

Just convert them into improper fractions and put parenthesis around the numbers with a division symbol in the middle of the two numbers.

Ex. (3/2)*(4/3)

Answer:

k = 5

Step-by-step explanation:

Since the equation is y = kx and x equals 3 while y equals 15, in order to solve this equation we are going to have to substitute the variables with their answers:

x = 3

y = 15

15 = 3k

Now we divide 3 from both 3x and 15 to segregate the variable x:

15/3 = 3k/3

5 = k

Now to check our work we are going to substitute 5 for the variable k, 3 for the variable x and 15 for the variable y.

y = kx

15= (5)(3)

15 = 15

Tada, I hope this helps you!

Answer:

k=5

Step-by-step explanation:

y=kx     Also meaning   y = k times x

x=3      y=15      

y divided by x   = 15 divided by 3 = 5

k=5

Lets Check Our Work

y=kx

15=?3

? times 3 is 15  = 5

Answer:10 inches

Step-by-step explanation: 4+4+1+1=10The perimeter of a rectangle is the sum total length of all of its sides.[1] A rectangle is defined as a quadrilateral, or a geometric shape with four sides. In a rectangle, both sets of opposite sides are congruent, meaning that they are the same length.[2] While not all rectangles are squares, all squares can be considered rectangles, and a compound shape may be composed of rectangles.[3]
