Mathematics
1 answer:
UkoKoshka [18]3 years ago

Answer:

b = 320

Step-by-step explanation:

a + b = 880

1 - 4/7 = 3/7 (restant A)

1 - 1/4 = 3/4 (restant B)

(3/7) . a = (3/4) . b

a = (7/4) . b

a + b = 880

(7/4) . b + b = 880

7b + 4b = 880 . 4

11 b = 880 . 4

b = 320

What is measure of angle A?
Goryan [66]

Answer:

A=53.13\°

Step-by-step explanation:

The figure shows a right triangle.

To calculate the measure of the angle A, you can use the inverse trigonometric function arctangent:

\alpha=arctan(\frac{opposite}{adjacent})

Identify the angle \alpha, the opposite side and the adjacent side:

\alpha=A\\opposite=4cm\\adjacent=3cm

Substitute into \alpha=arctan(\frac{opposite}{adjacent}).

The measure of the angle A is:

A=arctan(\frac{4}{3})\\\\A=53.130\°

Rounded to the nerarest hundreth:

A=53.13\°

My homework says name a 2 digit odd number that is prime. name a 2 digit odd number that is composite.
lidiya [134]
2 digit meaning that it has 2 numbers. For example, 66 is a two digit number.
Now, they also said it must be prime, meaning that its factors can only be 1 and itself. 
Also, it must be odd. 

Answer:  67

Now, do the same, except the number must be composite, as meaning that it has other factors.

Answer is 0.396
To make it easier, I converted the fraction to a decimal (0.99), then multiplied 0.99 • 0.4 which will equal 0.396 or 99/250.
