To solve this problem you can do a proportion
\frac{x}{215}  =  \frac{35\%}{100\%}
to find 'x', we have to cross multiply the numbers.
215 \times 35
and
100 \times x
this will get you
7525 = 100x
to get 'x', we have to divide by 100 on each side
\frac{7525}{100}  =  \frac{100x}{100}

your answer will be
75.25 = x
so, Chris must raise 75.25 dollars by himself

Baseball Ichiro Suzuki holds the American League record for the most hits in a single baseball season. In 2004, Suzuki had a tot
mamaluj [8]

Let Home runs = X

Triples would be X-3 ( 3 less triples than home runs)

Doubles would be 3x ( 3 times as many doubles as home runs)

Singles would be 45(x-3) ( 45 times as many singles as triples)

Simplify the equation for singles to be 45x-153

Now you have X + x-3 + 3x + 4x-135 = 262

Simplify:

50x - 138 = 262

Add 138 to both sides:

50x = 400

Divide both sides by 50:

x = 400/50

x = 8

Home runs = x = 8

Triples = x-3 = 8-3 = 5

Doubles = 3x = 3(8) = 24

Singles = 45(x-3) = 45(8-3) = 45(5) = 225

Express your answer in scientific notation. 4.9\cdot 10^{5} - 5.8 \cdot 10^{4} =4.9⋅10 5 −5.8⋅10 4 =4, point, 9, dot, 10, start
tatyana61 [14]

Answer:

4.32*10^{5}

Step-by-step explanation:

Given the expression 4.9*10^{5}-5.8*10^{4}, to solve the expression, we need to write both scientific notation to the same power of 10.

5.8*10^{4} is \ expressed\  as \ 0.58*10^{5}

The expression above becomes 4.9*10^{5}-0.58*10^{5}. On taking the difference;

4.9*10^{5}-0.58*10^{5}\\= (4.9-0.58)*10^{5} \\= 4.32*10^{5}

The final expression gives the right answer

A coin was flipped 150 times. The results of the experiment are shown in the following table:
ella [17]
It is 10% higher than the theoretical probability.Thats the answer because the theoretical odds are 50-50% (75 heads and 75 tails). 10% of 75 is 15, so 75+15=90, which means that it got a 10% higher than the theoretical probability.
