Answer:

242 inches²

Step-by-step explanation:

area = (1/2) · (p + q) · h (trapezoid formula)

(1/2)(13+24)(4)= 74

area= bh (rectangle)

(24)(7)= 168

168+74= 242

skelet666 [1.2K]

Let the percentage be x%,

then,

x% of 80 = 64
$\frac{x}{100} \times 80 = 64 \\ \frac{x}{10} \times 8 = 64 \\ \frac{x}{10} = \frac{64}{8} \\ x = 8 \times 10 = 80 \%$

He has ridden 80% of the total bike course.

For this right triangle, what is the cosine of angle C?

ollegr [7]

Answer:

A cos C = 12/13

Step-by-step explanation:

cos theta = adjacent side/ hypotenuse

cos C = BC/AC

But we don't know BC, but we can find it using the Pythagorean theorem

a^2 +b^2 = c^2

5^2 +BC^2 = 13^2

25 + BC ^2 =169

Subtract 25 from each side

BC^2 = 169-25

BC ^2 = 144

Taking the square root of each side

BC =12

cos C = 12/13

Choose a fraction that makes the following sentence true. 0.1 is a rational number because it can be written as ___.

pychu [463]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

0.1 is a rational number because it can be written as $\dfrac{p}{q}$ form.

So, we can write it as

$0.1=\dfrac{0.1}{1}\\\\=\dfrac{0.1\times 10}{1\times 10}\\\\=\dfrac{1}{10}$

so, it can be written as $\dfrac{1}{10}$

Hence, option 'a' is correct.

I need the formula not the answer thanks<br><br>x^{2} [/tex]>49

sladkih [1.3K]

X²>49
well, I don't know a formula but this is how I would solve it
I first solve x²=49 to obtain x=+/-7

so then would it be x>+/-7?
if we try 8 it works
if we try -9 it works

so answer is x>+/-7
basically x<-7 or x>7
