Answer:

3 1/2÷1/4 = 14

Step-by-step explanation:

Divide 3 x 2 + 1 / 1 by 1 / 4 by multiplying 3 x 2 + 1 / 1 by the reciprocal of 1/4

Multiply 3 and 2 to get 6

Add 6 and 1 to get 7

Multiply 7 and 4 to get 28

Divide 28 by 2 to get 14

Answer:

5) 1

6) 131

Step-by-step explanation:

5)

f(1) = -1 - 8 = -9

-9 + 10 = 1

6)

g(-9) = [tex]9^{2}[/tex] + 8(9) - 15 = 138

138 - 7 = 131

Answer:

Step-by-step explanation:

5.

f(x) = -x -8

substitute x with 1 in the equation of f(x)

f(1) +10 = -1 -8 +10 = -9 +10 = 1

6.

g(x)= x²+8x -15

g(-9) -7 = (-9)²+8(-9) -15 -7 = 81 -72 -22 = 81 - 94 = -13

Answer:

There are 72 spaces

Step-by-step explanation:

You would first have to do 27/3, which shows what 1/5 is. This would get you 9, then multiply that by 5 to find the amount of taken spaces. Add 27 and 45 to get 72 spaces.

Answer:

72 spaces in total

Step-by-step explanation:

If there are 27 empty spaces in a 3:5 ratio, that means that for every 3 spaces that are empty, there are 5 that are taken. We notice that there are 9 times of 3 spaces that are empty, so we must multiply 9 by 5 to get 45 spaces that are taken. We then add these up to get the total amount of spaces 27 + 45 = 72 spaces

Answer:

6.517%

Step-by-step explanation:

This is a multi-year investment and we are not working with a $1 initial investment. There is no mention of compounding so we will use formula A=P0⋅(1+r)N with A=$18,434 and P0=$14,320. We do not know the value of r. However, N=4 years. Substituting the values we have $18,434=$14,320⋅(1+r)4. Divide both sides of the equation by $14,320. Next, take the fourth root of both sides of the equation and subtract 1 to find the decimal form of r.

$18,4341.287291.065170.06517=$14,320⋅(1+r)4=(1+r)4=1+r=r

Finally, convert r to a percent.

r=0.06517×100%=6.517%

Answer:

X = 7.5

Step-by-step explanation:

First, divide 5 by 3 to find the scale factor:

5/3 = 1.667

Now, multiply 4.5 by 1.667 to find x:

x = (4.5)(1.667)

x = 7.5

Therefore, x is equal to 7.5.

Answer:

9413

Step-by-step explanation:

Given that :

Error = $2 ; Standard deviation (σ) =99 ; α = 95% = 0.95

Zα/2 = Z0. 05/2 = 1.96 (Z probability calculator)...

n = sample size

Recall:

n = ((Zα/2 * σ) / Error)^2

Using the formular above, the sample size n can be obtained ;

n = ((1.96 * 99) / 2)^2

n = 97.02^2

n = 9412.8804

n = 9413

Answer: x=68° because this triangle is a isoscele triangle which means that it haves 2 sides that are congruent and equivalent which means they have the same value and sides and are Congruent just means In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

The value of angle [x] is equivalent to 44°.

We have a triangle as shown.

We know, the angles opposite to equal sides are equal.

So, we can write -

x + 68° + 68° = 180°

x = 180° - (136°)

x = 44°

Therefore, the value of angle [x] is equivalent to 44°.

The perimeter of the triangle if its two sides measure 6 inches and the other side measures 7 inches will be 19 inches.

According to the given question.

The measure of the two sides of a triange is 6inches each.

And the measure of the other side is 7 inches.

As we know that,a perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length or the perimeter of a shape is defined as the total length of its boundary.

Thereofre, the perimeter of the triangle if its two sides measure 6 inches and the other side measures 7 inches

= 6 inches  + 6 inches  + 7 inches

= 19 inches

Hence, the perimeter of the triangle if its two sides measure 6 inches and the other side measures 7 inches will be 19 inches.

Step-by-step explanation:

Answer:

The odds against Ishaq getting hired are 17:18

This means that are 17 scenarios where Ishaq does not get hired, out of 18 total scenarios.

This means that the left scenario is when Ishaq gets hired, then the odds of Ishaq getting hired is equal to 1:18.

a) We want to find the probability that Ishaq gets hired.

This will be equal to the quotient between the number of scenarios where Ishaq gets hired (1) and the total number of scenarios (18).

Then this probability is

P = 1/18 = 0.056

b) We want to find the probability where Ishaq does not get hired, we can use the same reasoning as above, this time we will take the quotient between the number of scenarios where Ishaq does not get hired (17) and the total number of scenarios (18).

P = 17/18 = 0.944

Answer:

y = -7/8x - 97/8

or 8y + 7x = -97

Step-by-step explanation:

7x + 8y = 18

=> 8y = -7x + 18

y = -7/8 + 18/8

If two lines are parallel, their slopes are equal. So slope is -7/8

given m = -7/8, y = -13, x = 1

y = mx + b

-13 = -7/8(1) + b

-13 = -7/8 + b

b = -13 + 7/8 = -104/8 + 7/8 = -97/8

so y = -7/8x - 97/8

=> 8y = -7x - 97

8y + 7x = -97

Answer:

[tex]P(x)=x^3+12x^2+45x+50[/tex]

Step-by-step explanation:

Roots of a polynomial

If we know the roots of a polynomial, say x1,x2,x3,...,xn, we can construct the polynomial using the formula

[tex]P(x)=a(x-x_1)(x-x_2)(x-x_3)...(x-x_n)[/tex]

Where a is an arbitrary constant.

We are given the following roots:

-5 multiplicity 2 (-5 twice)

-2 multiplicity 1

Thus, the polynomial is:

[tex]P(x)=a(x-(-5))(x-(-5))(x-(-2))[/tex]

[tex]P(x)=a(x+5)(x+5)(x+2)[/tex]

We are not given any clue about the value of a, so we choose a=1. Multiplying:

[tex]P(x)=(x^2+5x+5x+25)(x+2)=(x^2+10x+25)(x+2)[/tex]

[tex]P(x)=x^3+2x^2+10x^2+20x+25x+50[/tex]

Simplifying:

[tex]\mathbf{P(x)=x^3+12x^2+45x+50}[/tex]
