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:

all of them

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

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.

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:

Student 3 had the greatest percentage error.

Step-by-step explanation:

Student 1

Actual length = 50in

Measured length = 49in

Error = 50 - 49 = 1

Error% = 1/50 × 100

= 1 × 2

= 2%

Student 2

Actual length = 100cm

Measured length = 110cm

Error = 100 - 110 = 10

Error% = 10/100 × 100

= 10 × 1

= 10%

Student 3

Actual length = 2cm

Measured length = 2.5cm

Error = 2 - 2.5 = 0.5

Error% = 0.5/2 × 100

= 0.5 × 50

= 25%

Student 4

Actual length = 10ft

Measured length = 9½ft

Error = 10 - 9½ = ½

Error% = ½/10 × 100

= ½ × 10

= 1 × 5

= 5%

It would be the 2nd one down and 3rd one up is the correct answer just look a little closer and you will see what i mean there ages are and and they have a 3o sec head start and they ran 60 yards in 30 sec.

To find m,

m= Y2-Y1 / X2-X1

m= 10-5 / 4-2

m= 5/2

m= 2.5

To find b,

Use coordinate (4,10)

y=mx+b

10=2.5(4)+b

10=10+b

b=0

Answer:

[tex](f-g)(x)= x^2-4x-5[/tex]

Step-by-step explanation:

We have the two functions:

[tex]f(x)=x^2-3x-10\text{ and } g(x)=x-5[/tex]

And we want to find (f-g)(x).

(f-g)(x) is equivalent to f(x)-g(x).

Therefore:

[tex]\begin{aligned} (f-g)(x)&=f(x)-g(x)\\ &=(x^2-3x-10)-(x-5)\end{aligned}[/tex]

Simplify:

[tex]\begin{aligned} &=x^2-3x-10-x+5 \\ &=(x^2)+(-3x-x)+(-10+5) \\ &=x^2-4x-5\end{aligned}[/tex]

Therefore:

[tex](f-g)(x)= x^2-4x-5[/tex]
