Answer:

The car took 1.11 seconds to go 90 meters.

Step-by-step explanation:

Set up an equation:

Variable x = number of seconds to travel 90 meters

81 meters/1 second = 90 meters/x seconds

Take out the variables for now to focus on calculations:

81/1 = 90/x

Cross multiply:

81 × x = 1 × 90

81x = 90

Divide both sides by 81:

x = 1.111111111... seconds

Round to nearest hundredth (hundredth is the second decimal place):

x = 1.11

Answer:

4 and 1/2 yards

Step-by-step explanation: 27 times 6 162 divided by 36 inches (1 yard) gets you 4 and 1/2 yards

Jeremy uses 27 inches of the board for each birdhouse to build. he needs 4.5 yd of the board to make 6 birdhouses.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Jeremy uses 27 inches of the board for each birdhouse to build.

so, by the proportion

To Calculate how many inches of the board he need to make 6 birdhouses.

27/ 1 = x / 6

x = 6 * 27

x = 162 in

To convert inches to yards

1 yd = 36 in

1 in = 1/ 36 yd

162 in = 162 * 1/ 36 yd

          = 4.5 yd

Answer:

The answer would be 10.8

Step-by-step explanation:

By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).

The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

The ladder is making a right-angle triangle with a wall as shown below.

By Pythagoras's theorem,

x² = 30² - 24²

x = 18

By Pythagoras's theorem,

y² = 30² - (18 + 10)²

y = 10.77 feet

Hence "The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet".

Answer:

y=mx+b

Step-by-step explanation:

to find the slope, pick two points (easiest if its an even point without decimals). the equation to find slope is m= y2-y1/x2-x1. Once you plug those in, from the two points, you should get a fraction or whole number--depends if it's simplifiable or not. Then plug that in to point slope form: y-y1= m (<the slope) (x-x1). The negatives by y1 and x1 in this equation make the number either negative or positive--if the number is negative it turns positive, and if it's positive it turns negative. Once you plug in those values, you should distribute the slope to the parentheses and combine like terms.

Answer:

Second one : x=-8+1/2

Step-by-step explanation:

-4x+8=42

We move all terms to the left:

-4x+8-(42)=0

We add all the numbers together, and all the variables

-4x-34=0

We move all terms containing x to the left, all other terms to the right

-4x=34

x=34/-4

x=-8+1/2

Answer:

9

Step-by-step explanation:

For mean you add all your numbers then divide them by the amount of numbers you have;

divide 63 by the number of integers (not the amount)

63 divided by 7 would equal 9.
