Height:shadow
so 3.5:1.06 and is the same as 50.5:x
we treat it as a fraction and get
3.5/1.06 and x/50.5

they should be equal
we know that if we multiply two equal fractions, with one flipped, then we will get 1 exg 1/2=4/8 1/2 times 8/4=8/8=1

so 3.5/1.06=x/50.5 3.5/1.06 times 50.5/x=1
176.75/1.06x=1
multiply both sides by 1.06x
176.75=1.06x
divide both sides by 1.06
166.745=x
round up to hundreds place
166.75m=accutal height

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

finlep [7]

Answer:

The speed of a car is x miles per hour.

The total distance the car travels in

30 minutes is y. ....>>> y = 0.5x

The cost to produce a table, y, is two

times the cost to produce a chair, x. ..> y = 2x

The time required to bake a chocolate

muffin, y, is 2 minutes more than the

time required to bake a vanilla muffin, x.....>> y = x + 2

Tina’s age, y, is 5 years more than

her brother Tim’s age, x. .......>> y = x + 5

Step-by-step explanation: The only really tricky one is the "speed of the car ..." because the speed is given in miles per hour and the time is given in minutes so that is 0.5 hour times time

Otherwise, "times" means multiplication and "more than" means addition.

For each part, first decide which of the three methods sections will most easily enable you to sketch the surface. These are the

UkoKoshka [18]

Answer:

Step-by-step explanation:

We use these three methods

1. Generalized cylinder method

2. Surface of revolution method

3. Method of slices general quadratic

1. For A = x² = 4z + 8

We use the method of slices for general quadratic

2. X²-4y²-4z² = 16

We use the generalized cylinder method

3. Y² = z² + 2z²

We use surface of revolution

TiliK225 [7]

4(x+2)+2=14

4x+8+2=14

4x+10=14

Subtract 10 from both sides

4x=4

Divide by 4 on both sides

x=1
