Answer: 40%

Step-by-step explanation: What I like doing with problems like this is work backward, so that is how this explanation is going to work.

830*0.40=332 so that is how I got 40% now lets dig a little deeper.

How to find percent is take the whole and times it by the decimal of percent you want (eg. if 400 is my whole I want to find out what 30% of it is I would do 400*0.30)

So then we take our 830 times it by what we think best fits and that's how I solved it!

If you need any further help let me know!

Answer: The base is 18.3ft

Sam wants to build a wooden deck on his patio, which is in the shape of a parallelogram. The area of the patio is 280 ft2. Find the base. Round your answer to the nearest foot. (height=5x)(base=6x)

Step-by-step explanation:

Given;

Area = 280ft^2

height = 5x

Base = 6x

The area of the parallelogram A can be written as;

Area = base × height

A = b×h

Substituting the values of Area, base and height.

280 = 5x × 6x

280 = 30x^2

x^2 = 280/30

x = √(280/30)

Since the base = 6x ;

Substituting the value of x.

Base = 6x = 6(√(280/30))

Base = 18.3ft

The base is 18.3ft

Answer:

See Step by step explanation

Step-by-step explanation:

$(g+f)(x) = g(x) + f(x) = 7x-1\\(g'f)(x) = g(x)f(x) = (3x-1)(4x) = 12x^{2}-4x\\(g-f)(-2) = -(-2)-1 = 1$

The giraffe (using the ruler) is 11 cm.

1 cm : 50 cm

Multiply both sides by 11.

11 cm : 550 cm

There are 0.01 meters in 1 centimeter.

Multiply 550 cm by 0.01.

(550)(0.01) = 5.5

The giraffe's real length is 5.5 meters.
