Answer:

Step-by-step explanation:

45% means 45/100

of means *(times)

is means =(equals)

so:

(45/100)*x=17.1

if you solve that, x=38

Therefore, The Answer is 38

45% × ? = 17.1

17.1 ÷ 45% =

17.1 ÷ (45 ÷ 100) =

(100 × 17.1) ÷ 45 =

1,710 ÷ 45 =

38;

so 45% of 38 = 17.1

2.) Fill in the blank.

Montano1993 [528]

Answer:

E.) 1

Step-by-step explanation:

Firstly we will solve for L.H.S.

L.H.S. = $Csc^2\theta$

Since we know that $Csc^2\theta$ is the inverse of $Sin^2\theta$ .

So we can say that;

$csc^2\theta=\frac{1}{sin^2\theta}$

Now For R.H.S.

$Cot^2\theta+1$

Since we can rewrite $cot^2\theta$ as $\frac{cos^2\theta}{sin^2\theta}$ .

Now we can say that the R.H.S. is;

$\frac{cos^2\theta}{sin^2\theta}+1$

Now we add the fraction and get;

$\frac{cos^2\theta+sin^2\theta}{sin^2\theta}$

Now according to trigonometric identity;

$cos^2\theta+sin^2\theta=1$

So, $\frac{cos^2\theta+sin^2\theta}{sin^2\theta}=\frac{1}{sin^2\theta}$

Here,

$csc^2\theta=\frac{1}{sin^2\theta}$ and $Cot^2\theta+1$ = $\frac{1}{sin^2\theta}$

L.H.S. = R.H.S.

Hence $csc^2\theta=cot^2\theta+1$

Ax- bx > 2a-2b solve for x

Dima020 [189]

Answer:

If a<b, x<2

If a>b, x>2

Step-by-step explanation:

ax-bx>2a-2b, (a-b)x>2(a-b)

If a>b, x>2(a-b)/(a-b)=2

If a<b, x<2(a-b)/(a-b)=2

mel-nik [20]

Answer:

series of directions for a training script

Step-by-step explanation:

Kevin is writing a series of directions for a training script. These directions will teach employees that have just been hired the step by step process on how to create the burgers at Outrageous Burgers. This way the new employees know exactly how the fast-food chain makes their burgers and they will be prepared to perform their responsibilities when customers start to come in and they are left by themselves. The training script is basically a resource for new hires.

The distributive property combines blank and blank to make multiplying whole numbers simpler.

laila [671]

The distributive property combines multiplication with addition and multiplication with subtraction together in order to simplify the equation. It is named as such because the number outside of the open and close parenthesis are distributed to the terms inside. Say for example, the equation given is 5(2x - 3). According to the distributive property, you distribute 5 by multiplying to each of the terms inside the parentheses. The solution would be: 5*2x + 5*-3 = 10x - 15. As you can see, it involved multiplication with addition and subtraction. Generally, you just have to add all the terms while making sure you carry the sign of the integer along when you multiply them just as shown in my example.

For the following exercises, evaluate the function f at the values f(−2), f(−1), f(0), f(1), and f(2)

MatroZZZ [7]

Answer:

See below. I assume that (x) = 8x2 - 7x + 3 is really (x) = 8x^2 - 7x + 3

Step-by-step explanation:

Substitute the value of x given in f(x) into the equation f(x) = 8x^2 - 7x + 3

For example, f(0) would be f(0) = 8(0)^2 - 7(0) + 3. f(0) = 3

f(-2) would be f(-2) = 8(-2)^2 - 7(-2) + 3.

= 8*4 + 14 +3

= 32 + 17 therefore f(-2) = 49
