What is the perimeter of a triangle if two of its sides measure 6 in. and the other side
measures 7 in. ?

Answers

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.

A jeweler makes an ocean-inspired necklace using a total of 60 snails shells and shark teeth. The ratio of snail shells to shark teeth is 5:1. How many snail shells does he use?

Please help fast

Answers

Given that,

Total number of snails shells and shark teeth = 60

The ratio of snail shells to shark teeth is 5:1

To find,

Total no of snail shells used by the Jeweler.

Solution,

Let there are 5x snail shells and x shark shells.

According to question,

5x+x = 60

6x = 60

x = 10

Snail shell = 5x

= 5(10)

= 50

Hence, he uses 50 snail shells.

1. Explain how to determine the equation of the function with
the following zeros. Be sure to explain each step as you show
how to determine the equation.
-5 multiplicity 2
-2 multiplicity 1

Answers

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]

1 triangle ABC was dilated by a scale factor of 2 centered at the origin of the result was as image of triangle A'B'C shown on the coordinate plane below the vertices of triangle A'b'c' are -4,4 -4,6 and 2,4 what are the coordinates of the vertices ABC

Answers

Answer:

The coordinates of ABC are respectively (-2,2), (-2,3), and  (1,2).

Step-by-step explanation:

Dilation About the Origin

Given a point P(x,y), its dilation about the origin by a scale factor of k maps the point to a point P'(kx,ky).

If we are given the dilated point, then we can find the original point by dividing by the scale factor.

Triangle ABC was dilated by a scale factor of 2 about the origin mapping it to triangle A'B'C' with vertices A'(-4,4), B'(-4,6), and C(2,4).

The coordinates of triangle ABC are:

A=(-4/2,4/2) = (-2,2)

B=(-4/2,6/2) = (-2,3)

C=(2/2,4/2) = (1,2)

The coordinates of ABC are respectively (-2,2), (-2,3), and  (1,2).

Answer:

The coordinates of ABC are  (-2,2), (-2,3), and  (1,2).

The odds against Ishaq getting hired for a job are 17:18. Determine the probability

(a) Ishaq gets hired.

(b) Ishaq does not get hired.

Answers

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

A parking lot has 27 empty spaces. If the ratio of empty spaces to taken spaces is 3:5, how many spaces are there total?

Answers

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

  see below for instructions

Step-by-step explanation:

You will need to do these constructions yourself. We cannot put marks on your paper for you.

The instructions below apply to part 3. A subset of the instructions applies to parts 1 and 2. The tools you need are a compass and a straightedge.

__

1. Draw line AB, and mark point X on it.

2. Choose a suitable radius for your compass and draw arcs with that radius centered at X. Label the points of intersection with line AB points E and G.

__

From here, the instructions are the same for constructing a perpendicular bisector of any segment. In what follows, we are construction the perpendicular bisector of segment EG. Thus, these instructions apply directly to parts 1 and 2. Points E and G will refer to the end points of the segment you are bisecting.

3. Set your compass radius to more than half the distance between points E and G.

4. Draw an arc centered at E that extends above and below the center of segment EG.

5. Using the same radius, draw arcs centered at G that cross the arc you drew in step 4. Label the points of intersection point P and Q.

6. Draw line segment PQ. This is the perpendicular bisector of EG. (For part 3, it will go through point X.)

__

In the attached, we show the "arcs" as full circles. They need not be. They only need to have sufficient length to make sure they cross where they need to cross.

Answer:

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
