The outboard engine on Steve's boat uses a fuel-to-oil mixture in a 50:1 ratio. If Steve puts 2.5 gallons of fuel in the tank, h

Llana [10]

1 gallon = 128 fluid ounces
2.5 gallons = 2.5 x 128 = 320 fluid ounces

Steve's boat uses 50 fluid ounce of fuel to 1 fluid ounce of oil, thus
for 320 fluid ounce of fuel it will use 320/50 = 6.4 fluid ounce of oil.

Darpana solved the equation s = StartFraction a + b + c Over 3 EndFraction for a. Her steps are shown below: 1. Multiply by 3: s

Harman [31]

Answer:

Option (c) is correct.

Step-by-step explanation:

Given equation is :

$s=\dfrac{a+b+c}{3}$

The equation can be solved for a as follows :

Step 1.

Cross multiply the given equation

$3s=a+b+c$

Step 2.

Now subtract b on both sides

3s-b = a+b+c-b

3s-b = a+c

Step 3.

Subtract c on both sides

3s-b-c=a+c-c

⇒ a=3s-b-c

The statement that is true for Darpana is " In step 3, she needed to subtract c rather than divide".

Find (2.2 x 107)(5 x 108) (2.5 x 103)(8.8 x 105) expressed in scientific notation.

jarptica [38.1K]

Answer:

Scientific notation of the multiplication is $2.42\times 10^{25}$

Step-by-step explanation:

$(2.2\times 10^{7})(5\times 10^{8})(2.5\times 10^{3})(8.8\times 10^{5} )$

= $(2.2\times 5\times 2.5\times 8.8)10^{(7+8+3+5)}$

[Since $10^{a}\times 10^{b}=10^{(a+b)}$ ]

= $242\times 10^{23}$

= $2.42\times 10^{25}$

Therefore, the scientific notation of the multiplication is $2.42\times 10^{25}$
