Answer:
200
Step-by-step explanation:
1. 4 times 5 because there are 5 types in total and they make 4 of each type in each batch they bake. 4*5 is 20.
2. 20 times 10 because they make 10 batches and you know there are 20 in each batch. so 20 times 10 is 200.
200 is the answer.
Answer:
angle BED and angle DEB are the answers.
<span>here we can use Pythogoras' theorem.
in right angled triangles the square of the hypotenuse is equal to the sum of the squares of the other 2 sides.
hypotenuse is 19 cm. One side is 13 cm and we need to find the length of the third side.
19</span>²<span> = 13</span>²<span> + X</span>²<span>
X - length of the third side
361 = 169 + X</span>²<span>
X</span>²<span> = 361 - 169
X</span>²<span> = 192
X = 13.85 the length of third side rounded off to the nearest tenth is 13.9 cm</span>
Answer:
x=−6±3√5
