A construction worker is placing rivets in a new bridge. He uses 42 rivets to build the first 32 feet of the bridge. If the bridge is to be 2200 feet in length, predict the number of rivets that will be needed for the entire bridge.​

Answers

Answer 1

Answer:

42 rivets=32ft of the bridge

1 ft of the bridge =42/32 rivets

2200 ft of the bridge =42/32×2200=2887.5

2887 and half

rivets that will be needed for the entire bridge.

Maura is going to hire a makeup artist for a fashion show and is comparing prices. Evelyn charges $19 as a booking fee and an additional $89 per hour. Brenda charges $87 per hour, plus a booking fee of $21. Depending on the length of the show, the cost could end up being the same for either artist. How long would the show be? What would the cost be?

Answers

Step-by-step explanation:

Evelyn: Y=89x + 19

Brenda: Y=87x + 21

Punch in numbers for X until you get the same for both. Remember that X is hours and Y is total. the numbers with no letters is the fixed booking amount. cheers. Good luck :)

A tree casts a shadow 31 feet long when the angle of
elevation of the sun is 58º. Find the height of the tree.

Answers

Answer:

x=24.2198542

ROUND IF NEEDED

Step-by-step explanation:

We are trying to find the height of the tree or the vertical side

We are given

The angle of elevation or the angle at the ground ,38The horizontal length, 31.

Since we have a side that is adjacent to that angle and we are trying find backside that us opposite of that angle

we are going to use tangent

[tex] \tan(x) = \frac{opp}{adj} [/tex]

plug 38 in for x or theta, x for opp side and 31 for adjacent side

[tex] \tan(38) = \frac{x}{31} [/tex]

Multiply 31 by both sides to find x

x=24.2198542

ROUND IF NEEDED.

There is 5 yellow 3 red 4 green 2 blue and 2 white what is the probability of picking white then green

Answers

Answer:

2 (I think)

Step-by-step explanation:

4-2=2

Answer:

1/30

Step-by-step explanation:

the probability of picking white is 2/16 simplified to 1/8

the probability of picking a green would equal to 4/15

notice that it is not 4/16, because you already picked out one of the colours, and you are not replacing it, so if you take it out, then there is 15 left to pick from.

you would then multiply

1/8 x 4/15

= 4/120

simplified to

1/30

Can someone plz help me with this??

Answers

Answer:

it's the second choice (3=3)

Answer:

y = - x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (3, 1)

m = [tex]\frac{1-3}{3-1}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , then

y = - x + c ← is the partial equation

To find c substitute (1, 3 ) into the partial equation

3 = - 1 + c ⇒ c = 3 + 1 = 4

y = - x + 4 ← equation of line
