Find it the value of x.

Answer:

(B) 10

Step-by-step explanation:

f(s) = 4 + s × 12

f(1/2) = 4 + (1/2) × 12

= 4 + 6

= 10

Answer:

10

Step-by-step explanation:

4 + s x 12

4 + (s x 12)

s = 1/2

substitute for s

4 + (1/2 x 12)

Answer:

6/10

Step-by-step explanation:

Answer:

3/5 = 0.6 = 6/10 = 9/15 = 12/20 = 18/30 = 21/35 = ...

Step-by-step explanation:

Multiply the numerator and denominator by the same number:

3/5 = 6/10 = 9/15 = 12/20 = 18/30 = 21/35 = ...

Also, you can divide 3 by 5 to get 0.6

Answer:

see explanation

Step-by-step explanation:

Using the cofunction identity

sec(90 - x)° = cscx° , then

7A = 90 - 5A ( add 5A to both sides )

12A = 90° ( divide both sides by 12 )

A = 7.5°

Answer:

-$360.00 change

Step-by-step explanation:

Now there is either some information missing, like her starting total in the bank; or they want you to explain the net change.  But the way the question is worded it is stating she is paying $30 over 12 months.  This means she has paid $360.00 in that 12 months aka 1 year.  Her bank account should have had a balance.  So you could technically say B for balance.  B-30*12.  To get your answer.  Although there are many ways to write an equation expression of this question.  If you know the starting balance then it's better.  But you could assume her starting balance was $0.  Which would be 0-30M*12 where M could represent monthly.  And the same answer would occur of 360.  Is there more information?

30*12= X (x equals the total paid)

X-30*12 (if x is her balance before paying any money)

6n = 9

n = 1.5 Since n must be an integer, this is an extraneous solution. The premise is false.

The expression that has a term with a coefficient of 6 is бу.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The term "coefficient" refers to the numerical factor that is multiplied by a variable or variables in a term.

Out of the given expressions, only one has a term with a coefficient of 6, which is:

6y

Thus,

The expression that has a term with a coefficient of 6 is бу.

Answer:

the value of x is 17 cm

Step-by-step explanation:

The computation of x is shown below:

Here we applied the pythagoreans theorem

x^2 = a^2 + b^2

x^2 = 15^2 + 8^2

X^2 = 225 + 64

x^2 = 289

x = sqrt(289)

= 17

Hence, the value of x is 17 cm

Answer: EQUAL

Step-by-step explanation:

Just as you can do the same thing to both sides of an equation, you can do the same thing to both sides of a fraction.  15 = 5*3 and 21 = 7*3.  Thus, 5/7=15/21

Answer:

y <7

Step-by-step explanation:

15-y>8

Subtract 15 from each side

15-15-y>8-15

-y>-7

Multiply each side by -1, remembering to flip the inequality

-1 * -y > -7*-7

y <7

Answer:

C) 7=y=5x+11

B) m=-4/5, b=13/5

Step-by-step explanation:

Problem 1:

A function is linear if its slope is constant and/or its graph is straight (that means 1-degree polynomials only). Therefore, C is the only correct answer.

Problem 2:

Convert to slope-intercept form (y=mx+b):

4x+5y=13

5y=13-4x

y=13/5-4/5x

y=-4/5x+13/5

Now we can see that since the original equation is in slope-intercept form (y=mx+b), the slope, m, is -4/5, and the y-intercept, b, is 13/5, making option B the correct answer.

Answer:

81

Step-by-step explanation:

Set up a proportion to find how many total students there are [notice how females are on top and totals are on the bottom of the ratios]

[tex]\frac{4}{9}[/tex] = [tex]\frac{396}{x}[/tex] so cross multiply 4x = 396(9) so x = 891, if there are a total of 891 students and you need 1 teacher per 11 students then take 891/11 so you need 81 teachers.

You could set up another proportion 1/11 = x/891

If there are 396 female students, there are 81 teachers.

Suppose the  real measurements were "a" and "b"

Then their ratio will be formed as

[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]

where  is a common factor (not 1)

This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.

Thus, a = px, b = qx

First, Set up a proportion to find how many total students there are

[notice how females are on top and totals are on the bottom of the ratios]

So, 4/9 = 396 / x

then, cross multiply

4x = 396(9)

so x = 891,

if there are a total of 891 students and we need 1 teacher per 11 students then take 891/11.

Thus, you need 81 teachers.

Also, we could set up another proportion 1/11 = x/891

Hence,  If there are 396 female students, there are 81 teachers.
