Answer:
70° and 20°
let the other 2 angles be 7x and 2x
90+7x+2x=180
9x=180-90
x=90/9
x=10
7x=7x10
70
2x=2×10

Answer:
Spending will be more than $59 billion more than <u>4</u> years after 2000.
Step-by-step explanation:
Given:
![y=11.3x + 13.8](https://tex.z-dn.net/?f=y%3D11.3x%20%2B%2013.8)
x is the number of years.
Business spending is $59 billion.
Hence we can say that y = $59.
Now Substituting the value of y in above equation we will find the value of x in number of years.
![11.3x+13.8=59\\11.3x=59-13.8\\ 11.3x= 45.2\\\\x=\frac{45.2}{11.3} = 4 years.](https://tex.z-dn.net/?f=11.3x%2B13.8%3D59%5C%5C11.3x%3D59-13.8%5C%5C%2011.3x%3D%2045.2%5C%5C%5C%5Cx%3D%5Cfrac%7B45.2%7D%7B11.3%7D%20%3D%204%20years.)
Hence we can say that,
After 4 years after 2000 the spending will be more than $59 billion.
or
Spending will be more than $59 billion more than <u>4</u> years after 2000.
Answer: 94.5
Step-by-step explanation:
If average of 9 students is 94, their total will be 94x 9 = 846
If the 10th student scores 99, the new total is 846 + 99 = 945
So, the new average will be
945/10 = 94.5
