Answer:

(x+20) explains the elena walked 20 minutes more than Lin

Step-by-step explanation:

(x+20) explains the elena walked 20 minutes more than Lin

As given in the question that elena walked 20minutes more than lin means if elena walked x then lin walked (x+20) and also jada walked twice as long as elena means 2(x+20) and according to question jada walked 90 minutes means  2(x +20) = 90

Answer:

The statement which matches "x+20" in the equation is the the time walked by Elana.

Step-by-step explanation:

According to the question.

Elena walked 20 minutes more than Lin.

Jada walked twice as long as Elena.

Jada walked for 90 minutes.

So,

Lets Lin walked for 'x' minutes.

and

Elana walked for 'x+20' minutes.

The equation can be:

⇒ 2(x+20)=90

⇒ 2x+40=90

⇒ 2x+40-40=90-40

⇒ 2x=50

⇒ \frac{2x}{2} = \frac{50}{2}

⇒ x=25 minutes

So.

Lin walked for ''x'' minutes that is 25 minutes.

Elana walked for ''(x+20)'' minutes that is 45 minutes.

And Jada walked for ''2(x+20)'' that is 90 minutes.

And we see that the statement Jada walked for 90 minutes is proved in numerical way.

The statement which matches "x+20" in the equation is the the time walked by Elana.

SOMEONE PLEASE HELP ME WITH THIS!!!!! ITS GEOMETRY
Fudgin [204]

Answer:

KG = 7 (A)

m KIH = 28 (B)

m JIH = 96 (D)

m HKI = 68 (B)

m KJI = 84 (C)

Step-by-step explanation:

Notice that the triangle HKJ is identical to HIJ. Since there are lines drawn to each other and both triangles are identical, the lines KG and GI are the same. This means that it is 7.

The triangle KGJ is identical with IGH. Using the recognise angle property, we know that angle JKI is the same as KHI. This means that it is 28.

Angle JIH is the same as angle JKH. Since JKH is 180 - (KHI or 84), we know that the angle JIH is 96.

We can find angle HKI by subtracting 96 by 28 because we know that angle HKI is the same as JIH. This gives us 96-2 8 = 68.

Angle KJI is the same as KHI which is 84. Therefore, KJI is also 84.

Find the value of the test statistic z using z=^p−p√pq/n.
Anna007 [38]

Answer:

Option C - 4.71

Step-by-step explanation:

We are given the Test statistic for proportion as;

z = (^p − p)/√pq/n

From the question;

^p = 0.15

p = 0.1

q = 1 - 0.1 = 0.9

n = 800

z = (0.15 - 0.1)/√(0.1 × 0.9/800)

z = 0.05/√(0.09/800)

z = 4.71

Which statements describe the graph of y = 3√x-1+2 ? Check all that apply.
Reptile [31]

Answer:

The correct options are A, D and E.

Step-by-step explanation:

We are given the function y=\sqrt[3]{x-1} +2

From the graph below, we see that,

Domain and range of the function is the set of all real numbers.

<em>As y-intercept is the point where the graph of the function crosses y-axis.</em>

That is, y-intercept is obtained when x= 0.

So, on substituting, we have,

y=\sqrt[3]{0-1} +2

i.e. y=-1+2

i.e. y= 1

Thus, the y-intercept is (0,1).

<em>Also, x-intercept is the point where the graph of the function crosses x-axis.</em>

That is, x-intercept is obtained when y= 0.

So, on substituting, we have,

0=\sqrt[3]{x-1} +2

i.e. -2=\sqrt[3]{x-1}

i.e. -8=x-1

i.e. x= -7

Thus, the x-intercept is (-7,0).

Hence, the correct options for the function are,

A. The graph has a domain of all real numbers.

D. The graph has a y-intercept at (0, 1)

E. The graph has an x-intercept at (–7, 0).
