Answer:

∆PQR: Equilateral Triangle

∆PRT: Scalene Triangle

∆TQS: Isosceles Triangle

∆QNP: Right Triangle

Step-by-step explanation:

∆PQR is an Equilateral Triangle because all of its angles are equal (60°).

∆PRT is a Scalene Triangle because none of its sides are equal.

The triangle above it is equilateral, and one side length is 14, meaning all of its side lengths are 14.

This makes the top of ∆PRT 14. The hypotenuse is given and it’s 18.

The last side left is clearly shorter than both, meaning none of the sides are equal.

∆TQS is an Isosceles Triangle because 2 angles are equal.

The base angles are both 76°.

∆QNP is a Right Triangle because segment QN and PR are perpendicular, creating two 90° angles on both sides.

For number 10, I suggest using a graphing calculator or desmos to graph the points. (Or you can just add the points but I suggest graphing).

From there, you can count the length of each side.

Segment DE: 9

Segment EF: 8

Segment FD: 10

This makes ∆DEF in number 10 a Scalene Triangle because none of its sides are equal.

For number 11, I also suggest graphing the points and counting the sides.

Segment DE: 7

Segment EF: 9

Segment FD: 7

This makes ∆DEF in number 11 an Isosceles Triangle because 2 of its sides are equal.

Hope this helps! :)

Answer:

Answer:

53/10

Step-by-step explanation:

First do 10 time 5 to get 50 then add 3 for 53.

tl;dr: A.) [tex]\frac{53}{10}[/tex]

Hello!

A very easy way to write mixed fractions as improper fractions is to multiply the denominator and the whole number, and then add the numerator to your product. Make sure you keep the same denominator as before.

So, first you multiply.

10 · 5 = 50

Now, you add the numerator.

50 + 3 = 53

Remember to keep your denominator.

[tex]\frac{53}{10}[/tex]

Your answer is A.) [tex]\frac{53}{10}[/tex]

Answer: 81

Answer:

Basic Concept used:

Since D is the mid-point of EF,

ED will be equal to DF since D is in the middle of the line segment

We are given the following values for ED and DF

ED = 4x + 6  and  DF = 7x - 9

Solving for x:

Since ED = DF (D is the mid point)

4x + 6 = 7x - 9

9 + 6 = 7x - 4x

15 = 3x

x = 5

Finding the values of ED , DF  and EF:

we know that x = 5 (from the last section)

we are given the following values of the line segments:

ED = 4x + 6

DF = 7x - 9

EF (ED + DF) = (4x + 6) + (7x - 9)

Replacing x with 5 in each of these equations:

ED = 4(5) + 5 = 26

DF = 7(5) - 9 = 26

EF = (4(5) + 6) + (7(5)-9) = 26 + 26 = 52

Answer=B

(f+g)(x)=-3x-5

Step-by-step explanation:

f(x)=x+8.

g(x)=-4x-3.

(f+g)(x) means f(x)+g(x),So

(x+8)+(-4x-3)

(add all same terms together)

=(x+(-4x))+(8+(-3))

=-3x+5

so,

(f+g)(x)=-3x+5

Option A: the median is greater than the mean and the distribution has only one outlier

Explanation:

From the data median is definitely greater than mean as we can see from the data of siblings, median which is middle number is somewhere greater than the mean 3.5 from the question. Also from the definition of an oulier and given that the median is just one middle number in data, there is just one outlier in the data

Answer:

4 1/4 gallons

Step-by-step explanation:

The amount of gas in the tank is 1/4 of 17 gallons.

1/4 * 17 gallons = 0.25 * 17 gallons = 4.25 gallons = 4 1/4 gallons

4 1/4 or 17/4

What is a mixed fraction?

A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction.

Step 1: Multiply the denominator with the whole number. Step 2: Add the numerator to the product obtained from step 1. Step 3: Write the mixed fraction with the sum obtained from step 2 as the numerator and the denominator of the original fractional part of the mixed fraction.

Given,

Full tank capacity = 17 gallons

gasoline gauge shows = 1/4 of full tank

= 1/4 of 17 gallons

= 17/4 gallons

= 4 1/4 gallons

tl;dr: Manny can make 4 bookmarks.

Hello!

So, Manny has 1/2 yards of fabric, and it takes 1/8 yards of fabric to make a bookmark.

The total amount of bookmarks Manny can make is 4.

When you do 4 · 1/8, you'll see that it gives you 4/8, or 1/2 simplified. This is all of the yards of fabric Manny has.

Answer:

(1 , 4)

Step-by-step explanation:

2x = -y + 6

-4x + 3y = 8

2x = -y + 6

2x - 6 = -y

-2x + 6 = y

-4x + 3y = 8

-4x + 3(-2x + 6) = 8

-4x - 6x + 18 = 8

-10x + 18 = 8

-10x = -10

x = 1

-2x + 6 = y

-2(1) + 6 = y

-2 + 6 = y

4 = y

Answer:

the second one would be the correct anwser i think.

Step-by-step explanation:

Answer:

No real solutions

Step-by-step explanation:

You use the quadratic formula.

x = −b ± √(b^2 − 4ac)/2a where y = ax^2 + bx + c

b is 0, a is 1, and c is 4.

-0 ± √(0^2 − 4 x 1 x 4)/ 2(1)

±√(-16)/2

Split √(-16) into √(16) and √(-1).

Now, i = √-1

So you get ±√(-16) = ±4i.

The original equation was ±√(-16)/2.

±4i / 2 = ±2i

The answer is x = ±2i

(Note: ± means positive or negative)
