Help!!! It doesn’t give the isosceles congruent angles??

Answers

Answer 1

Answer: y = 11 , x =3

Step-by-step explanation:

Since its an isosceles triangle , two angles or two side are equal.

So lets take 5y - 3 as one of the equal angles, so

5y-3+ 5y-3 + 76 = 180 (angles in a triangles should add up to 180)

10y - 6 + 76 = 180

10y = 180 - 70

10y =110

y = 110/10

y = 11

Now, since we found y we need to find x.

Lets us take 8x and 13x - 15 as the equal sides.

8x = 13x - 15

8x - 13x = -15

-5x = -15

x = -15 / -5

x = 3

so we found the values of x and y !

Answer 2

Answer:

x = 3y = 11

Step-by-step explanation:

You want the values of x and y, given an isosceles triangle with congruent sides JK=8x and KL=13x-15, angle K=76°, and angle J=(5y-3)°.

Congruent sides

JK = KL

8x = 13x -15

15 = 5x . . . . . . add 15-8x

3 = x . . . . . divide by 5

Sum of angles

The sum of the angles in the triangle is 180°.

2(∠J) +∠K = 180°

2(5y -3) +76 = 180 . . . . substitute known values, divide by °

10y +70 = 180 . . . . . . simplify

y +7 = 18 . . . . . . . . divide by 10

y = 11 . . . . . . . . . subtract 7

The values of x and y are 3 and 11, respectively.

What would be the first step you would take in solving the equation 3 - 2x = 4(x + 15) ?

Answers

The first step would be x+15
I think

Answer:

Distribute the 4

Step-by-step explanation:

You should always distribute first then you should add the 2x. Then combine like terms. Then subtract 15 then divide by six. Then you get the answer x = -2.

A company that produces white bread is concerned about the distribution of the amount of sodium in its bread. The company takes a simple random sample of 100 slices of bread and computes the sample mean to be 103 milligrams of sodium per slice. Construct a 99% confidence interval for the unknown mean sodium level assuming that the population standard deviation is 10 milligrams.

Answers

Answer:

The 99% confidence interval for the unknown mean sodium level is between 100.42 milligrams of sodium per slice and 105.58 milligrams of sodium per slice.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.58.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.58\frac{10}{\sqrt{10}} = 2.58[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 103 - 2.58 = 100.42 milligrams of sodium per slice.

The upper end of the interval is the sample mean added to M. So it is 103 + 2.58 = 105.58 milligrams of sodium per slice.

The 99% confidence interval for the unknown mean sodium level is between 100.42 milligrams of sodium per slice and 105.58 milligrams of sodium per slice.

Emily and her twin sister Erica were each given $500 for their birthday. Emily deposits her money in an account that pays 4.75% interest compounded annually. Erica deposits her money in a 5% simple annual interest account. After 10 years how much more money will Emily have in her account?
A $22.41
B $45.26
C $250.00
D $295.26

Answers

Answer:

B $45.26

Step-by-step explanation:

After 10 years

Emily will have 500 * 1.045^10 = $795.26

Erica will have 500 + 10*0.05*500 = 500 * 1.5 = 750$

Emily will have $45.26 more.

The answer choice which correctly describe s the function g (x) for a restricted domain as required to be determined in the task content is; g (x) = ³√(x + 4) , x ≥ -4.

Which function correctly represents the function g (x) for a restricted domain?

As evident in the task content, the function which correctly represents the function g (x) for a restricted domain is to be identified.

By observation of the function;

g (x) = ³√(x + 4) , x ≥ -4.

As evident in the task content; the lowest value of g(x) is; 0.

By checking; when x = -4; the corresponding value of g (x) is;

g (-4) = ³√(-4 + 4)

g (-4) = 0.

On this note, the required function is; g (x) = ³√(x + 4) , x ≥ -4.
