Josh and Katya both work at a library making $9 per hour if Katya work seven more hours than Josh last week and they made $279 combined how many hours did Katya work
Answer:
19 hours
Step-by-step explanation:
You have 279. First, devide the 279 by 9(dollar amount).
279/9 = 31
So combined they work 31 hours. Subtract 7 from this, since we know Katya worked 7 extra hours. Youll now have 24. (31-7 = 24)
Next, divide this number in half, which will get you what they both worked before Katya worked an extra 7 hours.
24/2 = 12.
Now that we know they both worked 12 hours, we can just add back the 7 hours Katya worked.
12+7 = 19.
So the answer to how many hours katya worked will be:
19 hours

Answer:
cosA = 8/17
Step-by-step explanation:
cos = adjacent/hypotenuse
The number that is adjacent to angle A is 24 and the hypotenuse is 51
Plug the numbers into the cosine equation, which would look like:
Cos A = 24/51
You can simplify the fraction by dividing it by 3
So Cos A = 8/17 or 0.89130173...
the volume of a sphere is 4851 cubic cm find its diameter
Answer:
The diameter is 21 cm
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr³, or (in terms of the diameter) V = (4/3)π(d/2)³. This simplifies to
4πd³ πd³
V = ----------- = -----------
3·8 6
Now equate V = (πd³/6) to 4851 cm³. We must first solve this for d³ and then take the cube root of the result:
πd³ = 4851(6) = 29106.
Dividing this result by π yields 9264.7,
and taking the cube root of this is 21. The diameter is 21 cm

Desmond really like Legos. Last Saturday Desmond counted his Legos and realized that
he has 65 altogether! Desmond has 7 less green Legos than red Legos, and the amount of
blue Legos he has is two more than three times his red Legos. How many of each color
Lego does Desmond have?
Answer Quick.
Only reply if you have the answer please
Answer: 14 red, 7 green, 44 blue
Step-by-step explanation:
First, use the letter r as a variable to represent the number of red Legos. The number of green Legos (g) is 7 less than the number of red Legos, or g = r-7. The number of blue Legos (b) is 2 more than 3 times the number of red Legos, or b = 3r+2. The total number of Legos is the number of red + green + blue Legos, which can be represented as 65 = r+g+b.
Substitute the equations for g and b in. This should give you a final equation of 65 = r+(r-7)+(3r+2). To solve for the number of red Legos, first add up all of the terms to get 65 = 5r-5. Now add 5 to each side (70 = 5r). Finally, divide each side by 5 (r = 14).
To find the number of green Legos, substitute the number of red Legos (14) into the equation for the green Legos (g = r-7). This should get you the equation g = 14-7 which simplifies to g = 7.
To find the number of blue Legos, substitute the number of red Legos (14) into the equation for the blue Legos (b = 3r+2). This gives you the equation b = (3*14)+2. First, multiply 3 and 14 to get b = 42+2. Finally, add them together to get b = 44.

how do I do probabillty
Answer:
Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.
