102 3/5 steps

The bridge is 307 4/5 m long
Her steps are 3/10 m long
Divide the length of the bridge by the length of her steps

First change the 307 4/5 to 8/10 so we have a common denominator
(307 8/10)/(3/10)
Next change 307 8/10 to an improper fraction
Multiply the whole number by the denominator than add the numerator
(3078/10)/(3/10)=1,026/10
Now divide the numerator by the denominator
1,026/10=102 6/10
Which simplifies to 102 3/5

Find the area of the figure to the nearest tenth.

jenyasd209 [6]

Answer:

99.0 in²

Step-by-step explanation:

The area (A) of the sector of the circle is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{140}{360}$ ( where r is the radius )

Here r = 9, thus

A = π × 9² × $\frac{14}{36}$

= 81π × $\frac{14}{36}$ ≈ 99.0 in²

Sharon is painting her house. she needs 5 gallons of brown paint for every 7 gallons of white paint. How many gallons of white

Igoryamba

Answer:

19.6

Step-by-step explanation:

The ratio of brown paint to white paint is, 5:7 or $\frac{5}{7}$ so if he bought 14 gallons of white paint we need to figure out:

$\frac{5}{7} =\frac{14}{x}$

which we can as it only has one unknown:

5x=14×7

5x=98

x=19.6

So the answer is 19.6

Aleena expands 2xx+3-5(x-2) as 2x2+3-5x-10. Has she expanded it correctly? Please identify the mistakes and write the correct wa

Nimfa-mama [501]

The given expression is :

2xx+3-5(x-2)

We know that, $x{\cdot}x=x^2$

$=2x^2+3-5(x-2)\\\\=2x^2+3+(-5)(x)+(-5)(-2)\\\\=2x^2+3-5x+10$

Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
