plz help me solve this​

Answer:

Step-by-step explanation:

the answer is C

Answer:

n = 16, AC = 60, DE = 30

Step-by-step explanation:

DE joins the midpoints of 2 sides of the triangle and is half the length of the third side, that is

DE = [tex]\frac{1}{2}[/tex] AC , substitute values

n + 14 = [tex]\frac{1}{2}[/tex] (3n + 12) ← multiply both sides by 2 to clear the fraction

2n + 28 = 3n + 12 ( subtract 2n from both sides )

28 = n + 12 ( subtract 12 from both sides )

16 = n

Then

AC = 3n + 12 = 3(16) + 12 = 48 + 12 = 60

DE = n + 14 = 16 + 14 = 30

Step-by-step explanation:

step 1. m: m is the variable, 1 is the coefficient, 1 is the degree, constant is 0.

step 2. 3t^2 +4t - 6: t is the variable, 3 and 4 are the coefficients, 2 is the degree, -6 is the constant.

step 3. 2 - h: h is the variable, -1 is the coefficient, 1 is the degree (highest variable exponent), the constant is 2.

step 4. -7a^2: a is the variable, -7 is the coefficient (before the variable), 2 is the degree, the constant is 0.

Answer:

6 root 2

Step-by-step explanation:

Pythagous Therom

A^2 = B^2 + C^2

B^2 = C^2 - A^2

B^2 = 36 - (2 Root 3)^2

B^2 = 24

B = 2 root 6

Base x Height / 2 for area of Triangle

2 root 3 x root 24 = 12 root 2

12 root 2 / 2 = 6 root 2

The right triangle is the one where one of the angles is a right angle (90 degrees) or two of the sides are perpendicular.

In [tex]\Delta[/tex] ABC

h² = 6² -(2√3)²

h² = 36-2² × √3²

h² = 36- 4× 3

h² = 36- 12

h² = 24

h =√24

h = 2√6 cm

Area  = [tex]\frac{1}{2}[/tex]× BC × h

         = [tex]\frac{1}{2}[/tex] × 2√3 ×  2√6

        = 2√18

        = 6√2

compare it with A= K√2 So K= 6

Answer: 16

Step-by-step explanation:

This explanation is all based on the fact that I read 1S_4 as 1/4 which is the most sensable assumption.  

let b be base and h be height of the triangle

if each b and h is divided by 4

=> b/4 and h/4

using triangle area formula

1/2 x b/4 x h/4  = (bh)/32

the original triangle

=> 1/2 x b x h = (bh)/2

(bh)/32 x (something) = (bh)/2

that something is

(bh)/32/((bh)/2) = 16

Or

you could use the fact that the ratio of sides of those two triangles is 1 to 4 and because we are comparing the ratio of the area 1^2 to 4^2 which results in a 1 to 16 ratio which simply means you just have to multiply the smaller triangle by 16.

Answer:

Layla's data set has a greater spread than Elle's data set

Eplanation:

I just got it right on the test I took..

The conclusion is Layla’s data set has more outliers or extreme values than Elle’s data set.

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of population

N = number of observation of population

X = mean

μ = population mean

We are given that;

E and L collect data on library use from same students. L’s SD > E’s SD.

Now,

Since Elle and Layla collected data samples from the same population of students, we can assume that they have the same mean for their data sets. Hence, if Layla’s standard deviation is much larger than Elle’s standard deviation, it means that Layla’s data set has more variation or dispersion than Elle’s data set. In other words, Layla’s data set has more outliers or extreme values than Elle’s data set. This could be due to random sampling error or some other factor that influenced Layla’s data collection.

Therefore, by the standard deviation the answer will be Layla’s data set has more outliers or extreme values than Elle’s data set.

Step-by-step explanation:

y = 4x-1

2x+y = 5

2x+(4x-1) = 5

6x - 1 = 5

6x = 6

x = 1

Answer:

(1,3)

Step-by-step explanation:

Since we already have the variable to it self, we can substitute y=4x-1 into 2x+y=5.

So it would be 2x+(4x-1)=5

Remove the parentheses

Combine like terms

Move the constant to the right

Divide 6 on both sides to get the variable by it self.

x=1

Then we substitute x=1 into y=4x-1, so..

y=4(1)-1

y=4-1

y=3

So the answer would be (1,3).

Answer:

7in, 7in, and 15 in

Step-by-step explanation:

Based on the Triangle Inequality Theorem that states that the sum of any 2 sides of a triangle must be greater than the measure of the third side, we can find what set of lengths cannot form a triangle.

The only set that does not follow the theorem is the set with lengths 7in, 7in, and 15in. It does not follow the theorem because...

7 + 7 < 15 (which should not be true based on the theorem)

Let B = the weight of box B

Let 2B = the weight of box A

Let 2B + 30 = the weight of box C

B + 2B + 2B + 30 = 640

5B = 610

B = 122 pounds, weight of box B

2B = 2(122) = 244 pounds, weight of box A

2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

Answer:

(-2, 4)

Step-by-step explanation:

In the first equation substitute -2x for y, obtaining:  5x - 9(-2x) = -46

Then 5x + 18x = -46, or  23x = -46, resulting in x = -2

Since y = -2x, y = -2(-2) = 4

The solution is (-2, 4)

The value of x coming is -2 and the value of y=4 by plotting the equations 5x-9y=-46 and y=-2x.

A statement that the values of two mathematical expressions are equal.

How to plot graph of an equation?

First we have to find the values of x and y as we can see in the figure1.

By plotting these points we can make graph of both the equations and the intersection point will be the solution of these equations.

Blue line is the line of the equation 5x-9y=-46 and the green line is the line of the equation y+2x=0
