Answer:
7 cake needs sugar = 60 .9 grams.
Step-by-step explanation:
Given : 87g of sugar is needed to make 10 cakes.
To find : How much sugar is needed for 7 cakes.
Solution : We have given
10 cakes needs sugar = 87 g .
1 cake needs sugar = = 8. 7
7 cake needs sugar = 8 .7 * 7 = 60 .9 g
7 cake needs sugar = 60 .9 grams.
Therefore, 7 cake needs sugar = 60 .9 grams.
Answer:
Yes!
Step-by-step explanation:
We know that right triangles follow the Pythagorean Theorem, where
So we will put our side lengths into this formula, keeping in mind that c = the hypotenuse, which is the longest side. a and b are fairly arbitrary.
If this works, we know it's a right triangle.
1089 + 1936 = 3025
3025 = 3025
It worked! It's a right triangle!!
Answer:
5 rad
Step-by-step explanation:
Recall that the length of an arc of circumference is given by the formula:
, where
is the subtended angle [in radians] from the circumference's center.
Therefore in this case, you know the arc length (81.5 cm), and the radius (16.3 cm), and can solve for the angle using the above equation as shown below:
