Answer 1

Answer:

Her proportion does not have corresponding parts in the same position.

Step-by-step explanation:

Sharon is drawing up a plan for building a reduced Eiffel Tower on her backyard patio. She has room to make a base of 5 feet. Her work is shown below.

What was Sharon’s error in finding the missing height measurement for her reduced tower?

Her proportion does not have corresponding parts in the same position.

For cross products, she needed to multiply 1050(328) and 5(x).

She needed to divide both sides by 1640, instead of 1050.

She needed to round down to 1.5 feet.

Height : base = 1,050 : 328

She has room to make a base of 5 feet.

Height : base = x : 5

1,050 : 328 = x : 5

1,050 / 328 = x / 5

Cross product

1,050 * 5 = 328 * x

5,250 = 328x

Divide both sides by 328

x = 5250 / 328

= 16.006

Approximately 16

Sharon's error:

Her proportion does not have corresponding parts in the same position.

What is the slope of a line that is perpendicular to the graphed line?

Answers

Answer:

The slope of the line perpendicular to the graphed line is 2.

Step-by-step explanation:

The Slope of a Line

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The graphed line passes through two visible points (0,4) and (8,0). Thus, its slope is:

[tex]\displaystyle m=\frac{0-4}{8-0}[/tex]

[tex]\displaystyle m=\frac{-4}{8}[/tex]

Simplifying:

[tex]\displaystyle m=-\frac{1}{2}[/tex]

Two lines of slopes m1 and m2 are perpendicular is:

[tex]m_1.m_2=-1[/tex]

Suposse the given line has slope [tex]m_1=-\frac{1}{2}[/tex]. To find m2, we solve the above equation:

[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]

Substituting:

[tex]\displaystyle m_2=-\frac{1}{-\frac{1}{2}}[/tex]

Operating

[tex]m_2=2[/tex]

The slope of the line perpendicular to the graphed line is 2.

If a truck that is traveling at 15 mph speeds up to 45 mph in 10 seconds, what is the truck’s acceleration?

Answers

Answer:

3miles per hour^2

Step-by-step explanation:

given data

initial speed u= 15mph

final speed v=45mph

time taken t= 10 seconds

Step two:

Required

acceleration a=?

applying the first equation of motion

v=u+at

substitute we have

45=15+a*10

45=15+10a

make a subject of the formula

45-15=10a

30=10a

divide both sides by 10

a=30/10

a=3miles per hour^2

Step-by-step explanation:

A mixed number is a number that contains an integer with a proper fraction eg: [tex]1\frac{1}{2}[/tex]. The fraction that is given is improper and can be turned into a mixed number to simplify it.

First, we need to find how many times 15 goes into 62:

Answers

Answer:

$105

Step-by-step explanation:

The thicker wall takes 345 -205 = 140 more blocks. Each of those costs $0.75, so the added blocks will cost ...

140 × $0.75 = $105

The thicker wall will cost $105 more.

A new video game is expected to sell 120 copies the first hour at a local game store. After that, the sales will follow the function s(x) = 15(x - 1) where x is the number of hours. What is the
function that shows total sales, including the first hour? (1 point)
s(x) = 15(x - 1) - 120
s(x) = 120x - 15
Os(x) = 120 + 15(x - 1)
Os(x) = 120 - 15(x - 1)

Answers

Answer:

X=104

Step-by-step:

Sorry IF my answer is wrong

Answer:

Os(x) = 120 + 15(x - 1)

Step-by-step explanation:

The total sales will be the sum of the constant 120 copies that were sold in the first hour and the sales in the subsequent hours, represented by the function s(x) = 15(x-1).

Thus, add 120 to the function s(x).

(-12,18)

Answers

Answer: (24,-9)

(0,9)

(4,6)

Step-by-step explanation:

3x + 4y = 36

Using (3,-2) will be:

= 3(3) + 4(-2)

= 9 - 8 = 1

Using (1,7) will be

= 3(1) + 4(7)

= 3 + 28 = 31

Using (0,0) equals to 0

Using (24,-9) will be:

= 3(24) +4( -9)

= 72 - 36 = 36

Using (0,9) will be:

= 3(0) + 4(9)

= 0 + 36 = 36

Using (4,6) will be:

3(4) + 4(6)

= 12 + 24

= 36

Using (-12,18) will be:

= 3(-12) + 4(-18)

= -36 - 72

= -108

The correct options are (24,-9), (0,9 and (4,6)
