Ashley simplified the following expression with the given steps 2(x+4)-(2x-8) 2x+4-2x-8 2x-2x+4-8 0-4 -4 Explain to her what her error was and how to correct it

Answers

Answer 1
First step, her distributive property was wrong. 2(x + 4) should be 2x + 8.
Since she made a mistake on the first step, all her equation messed up.
2x + 8 - 2x - 8
The correct answer would be 0

Read the excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde.

This hall, in which he was now left alone, was a pet fancy of his friend the doctor’s; and Utterson himself was wont to speak of it as the pleasantest room in London. But tonight there was a shudder in his blood; the face of Hyde sat heavy on his memory; he felt (what was rare with him) a nausea and distaste of life; and in the gloom of his spirits, he seemed to read a menace in the flickering of the firelight on the polished cabinets and the uneasy starting of the shadow on the roof. He was ashamed of his relief, when Poole presently returned to announce that Dr. Jekyll was gone out.

Which statement best describes how the author establishes mood in the excerpt?

a.The author’s description of the grand room creates an admiring mood.
b.The author’s description of physical symptoms creates an anxious mood.
c.The author’s mention of Utterson’s thoughts creates a sentimental mood.
d.The author’s mention of Utterson’s spirits creates a spiritual mood.

Answer:

b.The author’s description of physical symptoms creates an anxious mood.

09) The ratio of the number of jackfruit in baskets P, Q

in basket Pis 48 more than the number of
jackfruit in basket Q. Calculate the total number
of jackfruits in the three baskets.
A 121 B 144 C 156 D 169​

Answers

Answer:

156 jackfruits

Step-by-step explanation:

Let there are 6x jackfruit in baseket P, 2x in basket Q and 5x in basket R.

The total number of jackfruit  in basket P is 48 more than the number of  jackfruit in basket Q. ATQ,

6x = 48 + 2x

Solving for x.

6x - 2x = 48

4x = 48

x = 12

Jackfruits in basket P = 6x = 6(12) = 72

Jackfruits in basket Q = 2x = 2(12) = 24

Jackfruits in basket R = 5x = 5(12) = 60

Total no of jackfruits = 72 + 24 + 60

= 156

So, there are 156 jackfruits in the three baskets.

Answers

Answer:

5563.85 But round the nearest whole number is 5564

Step-by-step explanation:

Formule is P=Ie^(r)(t)

If, In 2010 the Network Club membership was 2,500. With an annual growth rate of approximately 8%, compounded continuously,  then 5563.85 is the population in 2022.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given,

In 2010 the Network Club membership was 2,500.

Annual growth rate of approximately 8%

8% is converted to decimal value by dividing 8 with 100

8/100=0.08

[tex]P=Ie^{rt}[/tex]

p is the final population

I is the initial population

[tex]p=Ie^{0.08(10)}[/tex]

[tex]p=2500e^{0.8}[/tex]

p=5563.85

Hence, 5563.85 is the population in 2020.

Hey hope someone can figure this out hopefully it's not that hard.

A chocolate box has the shape of a prism with a base that is a
rhombus. Each side length of the rhombus is 3.6 cm.
The angles between adjacent sides of the base are 60° and 120°.
The prism is 10.8 cm long.

a) Draw a net for this box.
b) How is your net different from the cardboard net from
which the box is made? Explain.

Answers

Part (a)

See the diagram below for the net for this box. We have two rhombuses that are the two bases of the rhombic prism. The six rectangles form the lateral sides.

In geometry, a net is effectively the outer surface of a 3D object, but it has been laid flat on a plane. Think of unwrapping a present without throwing any pieces away. The net would be the wrapping laid out flat. As another example, a net of a cardboard box would be laying the box flat. So you're unfolding the box. This is mentioned in part (b).

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

Part (b)

The main difference from this net compared to a net for a cardboard box is that everything is a rectangle for a cardboard box. This is because a cardboard box folds up into a rectangular prism.

So in the diagram below, you'll replace each rhombus with a rectangle. You'll make all four angles 90 degrees.

1 Which is the equation of a line that has a slope of and passes through point (2, -3)? O y = 1/2 X - 4 O y-x-2 O y=;x+2 O y=zx+3​

Answers

Answer:

y = (1/2)x - 4

Step-by-step explanation:

every equation has a slope of (1/2)

Then we should only consider the passing through point.

y = (1/2)x - 4

R.H.S : (1/2)x - 4. (substitute x= 2)

= -3

= L.H.S

it is passing through point (2,-3)

The equation of the line is y = (1/2)x - 4.

The correct option is (A).

What is slope?

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

As per the given data:

We are given the slope of the line.

We are also given the point through which the line passes.

Slope of the line = 1/2

Point through which the line passes = (2, -3)

From the slope-intercept form, the equation of any line can be written as:

y = mx + c

where m is slope and c is the y intercept

m = 1/2

y = (1/2)x + c

Line passes through (2, -3)

-3 = (1/2) × 2 + c

c = -4

The equation of the line is y = (1/2)x - 4

Hence, the equation of the line is y = (1/2)x - 4
