Answer: James will bake 48 cookies.

Step-by-step explanation:

We know that James can bake 12 cookies in 15 minutes. So, we can multiply both amounts ( the amount of cookies and the minutes it takes) to solve this question. First, ask " How many 15 minutes are in 60 minutes?" Or, 15 multiplied by what makes 60? The answer to this is 4. 15 minutes x 4= 60 minutes. Now, all we have to do is multiply the other side by the same amount. 12 cookies x 4 =48 cookies. So, he bakes 48 cookies.

Grade 8- The Pythagorean Theorem
aleksandr82 [10.1K]
1) pythagorean theorem = a2 + b2 = c2
SO:
10^2 + 6^2 = c2
100 + 36 = c2
136 = c2
Diagonal should equal about 11.66 meters

2)  pythagorean theorem = a2 + b2 = c2
SO:12.7^2 + 8.9^2 = c2
161.29 + 79.21 = c2
240.5 = c2
Elevation should equal about 15.1 degrees

Lisa [10]

Answer:

640 yard²

Step-by-step explanation:

From the question,

The surface are of a triangular prism is given as

A = bh+2ls+lb.................. Equation 1

Where A = Surface area of the triangular prism, b = base of of the triangular face, h = height of the triangular face, l = length of the triangular prism, s =  length of one of the other sides of the triangle

Given: l = 17 yards, b = 12 yards, h = 8 yards, s = 10 yards.

Substitute these values into equation 1

A = [(12×8)+(2×17×10)+(17×12)]

A = 96+340+204

A = 640 Yard²

Angle A= ? <br> HELP HELP HELP
vazorg [7]

Answer:

A = 41.41

Step-by-step explanation:

Since this is a right angle, we can use trig functions

cos A = adjacent/ hypotenuse

Cos A = 6/8

Taking the inverse cos of each side

cos ^ -1 ( cos A) = cos ^-1 ( 6/8)

A =41.40962211

Rounding to the nearest hundredth

A = 41.41
