Answer: 2.7 hours
Step-by-step explanation:
Hi, to answer this question we simply have to calculate the amount of time that takes making one batch of dinner rolls, by adding the individual times of, kneading, resting and baking.
Mathematically speaking
0.7 hours +1.6 hours +0.4 hours = 2.7 hours
It takes 2.7 hours to make each batch of dinner rolls.
Answer:
404.2
Step-by-step explanation:
To get the answer you should multiply 860 by 47% which is 0.47.
Answer:
x= 2/6
Step-by-step explanation:
add 3x to both sides
add 1 to both sides
divide 6 to both sides to isolate x
x = 2/6
For #1 you have one leg of a right triangle measuring 4000 (the height of the mountain) and the other leg is 3000 (the distance that Mario is from Jenna). The angle of elevation is the one on the base of the triangle across from the right angle. To find the measure of the angle, use the tangent ratio: tan(A)=4000/3000, which could be simplified to tanA = 4/3. Do that on your calculator using the inverse tangent function to get that the angle of elevation from Mario to Jenna is 53 degrees.
For #2 you have another right triangle situation where the length of the hypotenuse is 20 and the base leg is 10. You are finding again the base angle across from the right angle. Use the cosA=10/20, aka cosA=.5. Again use the inverse cos function on your calculator to find the angle in question is 60 degrees.
11 boys and 8 girls because you divide it in half the add 2 and subtract 1. That isn't the wy you are supposed to do it but it works and makes since in my head.
