Answer:

76.16 kilograms of food

Step-by-step explanation:

Number of cyclist = 32

Food per cyclist = 8.33 kilograms

Days of the trip = 7 days

Food per cyclist per day = 8.33 kg / 7

= 1.19kg food per day for each cyclist

how many kilograms of food will the group be carrying at the end of Day 5?

5 days out of 7 days = 2 days

Each cyclist will have to carry = 2 × 1.19 kg of food for the remaining two days

= 2 × 1.19

= 2.38 kilograms of food for two days

32 cyclist for 2 days = 32 × 2.38 kg of food

= 76.16 kilograms of food

The group will be carrying 76.16 kilograms of food at the end of Day 5

The side lengths of the following right triangle 15,20 and 25, as shown below. The altitude from the right angle splits the hypo

Answer:

$h = 12$

$x = 9$

$y= 16$

Step-by-step explanation:

Given

The attached triangle

Required

Find h, x and y

Let the base of the triangle be 15.

So, the area is:

$A = \frac{1}{2} * 15 * 20$

$i.e\ height = 20$

$A = \frac{1}{2} * 300$

$A = 150$

Let the base of the triangle be 25.

So, the area is:

$A = \frac{1}{2} * 25 * h$

$i.e\ height = h$

$A = \frac{1}{2} * 25h$

Substitute $A = 150$

$\frac{1}{2}*25h = 150$

Solve for h

$h = \frac{150 *2}{25}$

$h = 6 *2$

$h = 12$

Considering the smallest triangle

$Hypotenuse = 15$

So:

$15^2 = h^2 + x^2$

$15^2 = 12^2 + x^2$

This gives:

$15^2 - 12^2 = x^2$

$81 = x^2$

Take square roots

$9 =x$

$x = 9$

Solving for y

$x + y = 25$

$y= 25 - x$

$y= 25 - 9$

$y= 16$

PLEASE ANSWER ASAP

Nastasia [14]

Answer:

y = 4 $(2)^{x}$

Step-by-step explanation:

For an exponential function in standard form

y = a $(b)^{x}$

To find the values of a and b, use ordered pairs from the table

Using (0, 4 ), then

4 = a $b^{0}$ ( $b^{0}$ = 1 ), so

a = 4

y = 4 $b^{x}$

Using (1, 8 ), then

8 = 4 $b^{1}$ = 4b ( divide both sides by 4 )

2 = b

Thus

y = 4 $(2)^{x}$ ← exponential function

The width of a rectangle is 4 inches less than the length. The perimeter is 60 inches. Find the length and the

coldgirl [10]

Answer:

Length=17

width=13

Step-by-step explanation:

W=width

L=length

Perimeter = 2w+2l since it's a rectangle

W=l-4 (given)

Plug into perimeter equation

Perimeter =(2l-8)+2l

=4l-8

60=4l-8

68=4l

17 =l

W=l-4=17-4=13

Which expression has the same value as the one below?

mihalych1998 [28]

Answer:

Option A

Step-by-step explanation:

22+(-32) is the same thing as 22-32.

$22-32=-10$

<h3>Let's see if the given options are equal:</h3>

Option A:

$22+(-22)+(-10) \\22-22-10\leftarrow \text{Distribute -1 into the Parentheses.} \\0-10\\\boxed {-10}$

Option A's expression has the same value as the expression given.

Option B:

22+(22)+(-10)

$22+22-10\\44-10\\\boxed {34}$

Option B's expression does not have the same value as the expression given.

Option C:

$22+(-22)+(10)\\22-22+10\\0+10\\\boxed {10}$

Option C's expression does not have the same value as the expression given.

Option D:

$22+0+32\\22+32\\\boxed{54}$

Option D's expression does not have the same value as the expression given.

<h3>The correct answer should be A: 22+(-22)+(-10).</h3>
