Answer:   LM = 57

==========================================================

Explanation:

A median of a triangle goes from a vertex to the midpoint of the opposite side. The three medians of this triangle are these segments:

The three medians intersect at the centroid point, which is point Q.

It turns out that the centroid cuts each median such that LQ is twice as long compared to QM. We can say

LQ = 2*QM

Applying the segment addition postulate and substitution, we then get,

LQ + QM = LM

2QM + QM = LM

3QM = LM

LM = 3QM

Now let's use LQ = 38 to find QM

LQ = 2*QM

38 = 2*QM

QM = 38/2

QM = 19

This then means,

LM = 3QM

LM = 3*19

LM = 57

Segment LM is 57 units long.

Answer:

I think the answer is 22.14

Step-by-step explanation:

Difference means substraction so to answer this I have to subtract.

26.4-4.26=22.14

Answer:

144

Step-by-step explanation:

I did the sum out :) :)

Answer:

28 houses per hour

Step-by-step explanation:

With regards to the above, we'll simply divide the number of houses by the hours spent

Number of houses = 112

Hours spent = 4

The rate at which the carrier delivers the mail is

= 112/4

= 28 hours per hour

Answer:

Answer:

It is B

Step-by-step explanation:

Took the test

Answer: A. and D.

Step-by-step explanation: Sorry if its wrong but that sounds right. The first week comes before the second week.

Answer:

x = -1

y = 4

Step-by-step explanation:

i believe this shape is a rhombus because the diagonals are perpendicular and bisectors, meaning m∡A = m∡B = m∡C = m∡D

so AC = CB = BC = DA

y + 1 = 2y - 3

1 = y - 3

4 = y

Plugging in 4 for 'y' means all sides are equal to 5

find x:  2x + 7 = 5

2x = -2

x = -1

Here's the answer .. feel free to ask any more qns.

Answer:

2.75

Step-by-step explanation:

Divide 13.75 by five.

Answer:

B

Step-by-step explanation:

if you solve all of them

2(4x) = 8x

a) 2 + 4x well you cant simplify more on that so no that wouldnt be the answer

b) (2 × 4)x = 8(x) = 8x

c) would equal 4 + 8x

d) 8 + 8x

hope I helped ;)

Step-by-step explanation:

Exponential Equations

We need to recall some properties of exponentials to solve the equations:

[tex]x^a*x^b=x`{a+b}[/tex]

[tex]\displaystyle (x^a)^b=x^{ab}[/tex]

Equation A

[tex]\sqrt{448x^c}=8x^3\sqrt{7x}[/tex]

Squaring:

[tex](\sqrt{448x^c})^2=(8x^3\sqrt{7x})^2[/tex]

Simplifying the radicals:

[tex]448x^c=64x^6(7x)[/tex]

[tex]448x^c=448x^7[/tex]

If follows that

c=7

Equation B

[tex]\sqrt[3]{576x^d}=4x\sqrt[3]{9x^2}[/tex]

Raising to the third power:

[tex](\sqrt[3]{576x^d})^3=(4x\sqrt[3]{9x^2})^3[/tex]

[tex]576x^d=4^3x^3(9x^2)[/tex]

Operating

[tex]576x^d=64x^3(9x^2)=576x^5[/tex]

Thus:

d=5

Answer:

P = 28.57%

Step-by-step explanation:

Probability

The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.

The equation to calculate the probability is:

[tex]\displaystyle P=\frac{f}{n}[/tex]

Where f is the number of favorable cases and n is the total cases.

The spinner has n=7 equal spaces numbered 1 to 7. We will calculate the probability that the spinner lands on a 4 or a 6.

The set of favorable outcomes is {4,6} which gives a count of f=2.

The required probability is:

[tex]\displaystyle P=\frac{2}{7}[/tex]

P = 28.57%

Answer:

a). (-0.04x² + 3x + 49)

b). 79240

Step-by-step explanation:

a). Population of the pet dogs of a two is given by the expression,

   (38 + x - 0.04x²)

   And population of the pet dogs of the rest of the towns of the county by (2x + 21).

   Where x = Number of years from year 2007

   Therefore, total population of the county = (38 + x - 0.04x²) + (2x + 21)

                                                                        = -0.04x² + (x + 2x) + (38 + 21)

                                                                        = (-0.04x² + 3x + 49)

b). Difference of years between year 2007 and 2019 = 12 years

     Therefore, predicted population in year 2019 = -0.04(12)² + 3(12) + 49

                                                                                  = 36 + 49 - 5.76

                                                                                  = 79.24

     Since, population is in thousands,

     Therefore, total population of the county = 79.24 × 1000 = 79240

Answer:

6.2 gallons of orange juice left.

Step-by-step explanation:

Total orange juice = 8 gallons

Used orange juices to make popsicles = 1.8 gallons

We need to find how much orange juice does Tracy have left.

Left orange juice = Total orange juice - used orange juice

= 8 gallons - 1.8 gallons

= 6.2 gallons

Hence, 6.2 gallons of orange juice left.

Answer:

y=-2x-94

Step-by-step explanation:

You can do anything with the y-intercept. The line is parallel (same slope) and the y-intercept can be literally any number in the world. I would advise to not use negative or positive infinity though.

Answer:

Value of x = 5°

Value of y = 4°

Step-by-step explanation:

Given:

ABCD is a parallelogram

Find:

Value of x and y

Computation:
