Answer:

Okay the question is a little unclear, but if he's only doing english, science and history the answer should be  17/40

Step-by-step explanation:

1/5=8/40

3/8=15/40

8/40+15/40=23/40

40/40-23/40=17/40

ANSWER:

Study time for english = 1/5.
Study time for science = 3/8.

We will first equate the denominator of the fractions.

So, 1/5 × 8/8 = 8/40

3/8 × 5/5 = 15/40

8/40 + 18/40 = 23/40

Total time = 40/40 = 1.

So for history work, he used

40/40 - 23/40
17/40.

Step-by-step explanation:

When a denominator has a positive exponent we change it into an expression with a negative exponent and vice-versa, when a numerator has a positive exponent, we change it into a denominator with a negative exponent.

Answer:

x = 16

Step-by-step explanation:

The figure shown shows an inscribed angle F and central angle E. Both angles intercept the same arc.

Therefore, angle E is twice the measure of angle F, according to the central angle theorem of a circle.

Thus,

m<E = 2 * m<F

(x + 94)° = 2(55)

We can find the value of x with this equation.

x + 94 = 110

Subtract 94 from both sides

x = 110 - 94

x = 16
