Answer: He saved $12 per week
Step-by-step explanation:
I am confused you basically solved your own question but here is the explanation.
Isaiah gets $12 per week in his allowance, every two weeks he gets $24, so in twenty weeks he would have save $240. Here is an equation.
2W*10 = $240
W = weeks
2 weeks = $24*10 = $240
I hope this helps in anyway
Answer:
125 ml
Step-by-step explanation:
250 ml is required to make 8 pancakes, so in order to make half as many pancakes, you will need half as much milk.
250 ÷ 2 = 125
2x-5=25
Add 5 to both sides
2x-5+5=25+5
2x=30
Now, divide both sides to find x
2x/2=30/2
x=15
Nathan is 15 years old
To find Tasha's age, subtract 25 and 15
Therefore, Tasha is 10 years old
Hope I helped!
First let's find the angles a and b.
We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.
cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.
We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.
