Answer:

25 1/2 feet

Step-by-step explanation:

Answer:

25.5 ft

Step-by-step explanation:

Starting level: 33 ft

Each day the water recedes 0.5 ft.

Now we calculate the number of ft the water recedes in 15 days.

15 days * 0.5 ft/day = 7.5 ft

In 15 days, the water recedes 7.5 ft.

Level of water after 15 days:

33 ft - 7.5 ft = 25.5 ft

Answer: 25.5 ft

Answer:

-50

Step-by-step explanation:

The average rate of change is synonymous with the slope. Therefore, we will find the slope of the function from x=0 to x=3.

So, we will use the endpoints of the function.

At x=0, f(x)=150. Thus, we have the point (0, 150).

At x=3, f(x)=0. Thus, we have the point (3, 0).

Now, we can use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (0, 150) be (x₁, y₁) and let (3, 0) be (x₂, y₂). Substitute:

[tex]m=\frac{0-150}{3-0}=-150/3=-50[/tex]

Therefore, the average rate of change for the first three seconds is -50.

Answer:

The length of the side along the river is 140 m

Step-by-step explanation:

Equations

To solve the problem, we need to recall the area of a trapezium is:

[tex]\displaystyle A=\frac{b1+b2}{2}.h[/tex]

Where b1 and b2 are the lengths of the parallel sides and h is the height of the trapezium.

The field to be bought by Mohan has a trapezium shape with a side along the road of side x and a side along the river of side 2x, as stated in the problem.

Knowing the height is h=100 m, and the area is 10500 m2:

[tex]\displaystyle \frac{x+2x}{2}\cdot 100=10500[/tex]

Simplifying:

[tex]\displaystyle (3x)\cdot 50=10500[/tex]

[tex]150x=10500[/tex]

Dividing by 150:

[tex]x = 10500 / 150 = 70[/tex]

x = 70 m

2x = 140 m

The length of the side along the river is 140 m

Answer:

perimeter of triangle IJH= 17.5

Step-by-step explanation:

line IJ is a midsegment, so you can divide the segments FH and GH by 2.

that means segment IH= 4.5 and segment GH=6. segment IJ is given as 7.

add 4.5 + 6 + 7, which equals 17.5

Step-by-step explanation:

Answer:

Cost of tshirt = £7.29

Cost of what = £0.86

Step-by-step explanation:

2t +3h = 12; 10t + 15h = 60

5t + 4h =33; 10t + 8h = 66

15h -8h = -6

7h = -6; h = -6/7; h = 0.86

2t +3(-6/7) =12

14t -18 = 84

14t = 102; t = 102/ 14; t=7.29

Answer:

Step-by-step explanation:

all the sides are different than the other on the bottom of the  shape  the sizes have longer sides and one short at the bottom.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

If the amount of seed in a bird feeder decreases by 10.8 ounces in 5 days.

The change in the amount of seed in the feeder in 7 days is 15.12 ounces.

It is the quantity of an amount of something at a rate of one of another quantity.

Example:

A man can run 3 miles in 60 minutes.

The time to run 1 mile is 20 minutes.

We have,

The rate at which the amount of seed decreases.

10.8 ounces = 5 days

Divide both sides by 5.

10.8/5 ounces = 1 day

Multiply 7 on both sides.

7 x 2.16 ounces = 7 days

15.12 ounces  = 7 days

This means that in 7 days, the amount of seed decreases by 15.12 ounces.

Thus,

If the amount of seed in a bird feeder decreases by 10.8 ounces in 5 days.

The change in the amount of seed in the feeder in 7 days is 15.12 ounces.
