Answer:

12.5

Step-by-step explanation:

Area of Trapezium = 1/2 ( A + B ) × H

A = 2.5

B = 7.5

H = 2.5

1/2 ( 2.5 + 7.5 ) × 2.5=

1/2 ( 10 ) × 2.5=

5 × 2.5  = 12.5

Which calculator correctly shows the quotient 6.47x10^-15/3.36x10^-29
Gemiola [76]

1.92559524e+14

Step-by-step explanation:

6.47 x 10^-15 and 3.36 x 10^-29 are written in scientific notation. In this way, we have a quotient of two numbers written in scientific notation. To solve this problem, we have:

6.47/3.36 x 10^{[-15-(-29)]}=1.92559524 x 10^{(-15+29)}

Therefore 1.92559524 x 10^{14}  or 1.92559524e+14

Find the values of y = r(x) = ∛x for
eduard
We're being asked to find the values of y for \sqrt[3]{x} for specific values of x. Basically, we are taking the cube roots of these numbers.



r(-2.197) = \sqrt[3]{-2.197} = -1.3\\\\ r(-1.331) = \sqrt[3]{-1.331} = -1.1\\\\ r(0) = \sqrt[3]{0} = 0 \\\\ r(1.331) = \sqrt[3]{1.331} = 1.1\\\\r(2.197) = \sqrt[3]{2.197} = 1.3\\\\r(-3.375) = \sqrt[3]{-3.375} = 1.5\\\\r(4.913) = \sqrt[3]{4.913} = 1.7\\\\

The bakery sells each cake for $120. Last year, the bakery sold 98 cakes. How much money did the bakery earn selling cakes?
LuckyWell [14K]

Answer:

The bakery earned $11760 by selling cakes

Step-by-step explanation:

Cost of 1 cake = $120

Bakery sold cakes = 98

We need to find how much money did the bakery earn selling cakes?

We are given cost of 1 cake, if we multiply cost of 1 cake by 98 we can get cost of 98 cakes. Solving:

Cost of 1 cake = 120

Cost of 98 cakes = 120 x 98

                            = 11760

So, The bakery earned $11760 by selling cakes
