A covered bridge is 8 yards long. In a painting for sale at a gallery, the bridge in the painting to the actual length of the bridge. One salesperson says the ratio in simplest form is 5/8. Another salesperson says the ratio in simplest form is 5/24. Which ratio is correct? What error leads to the incorrect ratio?

Answers

Answer:

The ratio that is correct is 5/24.

The error that leads to the incorrect ratio is working with the different units of length.

Step-by-step explanation:

Here is the complete question:

A covered bridge is 8 yards long. In a painting for sale at a​ gallery, the bridge is 5 feet long. A customer wants to know the ratio of the length of the bridge in the painting to the actual length of the bridge. One salesperson says the ratio in simplest form is 5/8 Another salesperson says the ratio in simplest form is 5/24 Which ratio is​ correct? What error leads to the incorrect​ ratio?

Step-by-step explanation:

From the question,

A covered bridge is 8 yards long and in a painting at the gallery, the bridge is 5 feet long.

To determine the ratio of the length of the bridge in the painting to the actual length of the bridge,

First, we will convert both lengths to the same unit and then divide the length of the bridge in the painting by the actual length of the bridge.

Convert 8 yards to feet

1 yard = 3 feet

∴ 8 yards = (8 × 3) feet = 24 feet

The actual length of the bridge is 24 feet

The length of the bridge in the painting is 5 feet

Hence, the ratio of the length of the bridge in the painting to the actual length of the bridge is 5 feet ÷ 24 feet = 5/24

Hence, the ratio that is correct is 5/24.

The error that leads to the incorrect ratio is working with the different units of length (that is, not converting both length to the same unit before determining the ratio).

Step-by-step explanation:

2(p+12)=64

Step 1: Simplify both sides of the equation.

2(p+12)=64

(2)(p)+(2)(12)=64(Distribute)

2p+24=64

Step 2: Subtract 24 from both sides.

2p+24−24=64−24

2p=40

Step 3: Divide both sides by 2.

identify the slope of the line for the equation 1/6 x + 1/4

Answers

Answer:

y = 1/6x - 8/3

Step-by-step explanation:

The equation of a line in slope-intercept form is.

y = mx + b

where m represents the slope and b, the y-intercept.

Rearrange y + 2 = 1/6 (x - 4)  into this form

distribute bracket and simplify.

y + 2 = 1/6x - 2/3

⇒ y = 1/6x - 2/3 - 2

⇒ y = 1/6x - 8/3 ← in slope-intercept form

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.
What is the measure of B?

Answers

I believe it is 74°. Because translations preserve size

The measure of the angle B is 74 degrees.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.

If triangle ABC is translated 2 units up and 2 units right, that means that all the vertices of the triangle are translated by the same units 2 up and 2 right.

The angle sum property of a triangle;

80 + 26 + B = 180

B = 180 - 106

B = 74

Therefore, the size and shape of the triangle wouldn't change.

The triangle A'B'C' will still have the same size and shape, and all the sides will have the same length.

Hence, the measure of the angle B is 74 degrees.

If you want to simplify 6:4, it also makes an equivalent equation. To simplify this, we divide by the greatest number that both numbers can be evenly divided by. 6 and 4 can both be divided by 2, which is the biggest number we can divide both numbers by.

6/2=3

Help ASAP pleaseThank you TRUE OR FALSE???A writer is working on a research paper in which she argues that its important to be careful when consuming coconut oil and other coconut-based products. One of the paragraphs in her paper reads:According to a 2018 New York Times article, Coconut oils image has gotten a makeover in recent years, and many natural food stores stock the product. But despite a lot of hype about it, said Dr. Alice H. Lichtenstein, a Tufts University professor of nutrition science and policy who is vice chair of the federal governments dietary guidelines advisory committee, theres virtually no data to support the hype (Rabin). According to a CNN news report discussing coconut oil, Health organizations tend to discourage the use of coconut oil, which is more than 80% saturated fat. The American Health Association says its better on your skin than in your food, and it recommends that no more than 5% or 6% of your daily calories come from saturated fatsabout 13 grams per day. The association also advocates replacing coconut oil with healthy fats such as polyunsaturated fats and monounsaturated fats, like those found in canola and olive oils, avocados and fatty fish (Drayer, et. al). Additionally, Like other oils, coconut oil is calorie-dense, which means consuming large amounts without reducing other calorie sources can lead to weight gain. Just one tablespoon has 120 calories, about the same as a large apple or four cups of air-popped popcorn (Drayer, et. al).This paragraph effectively relates the writers source material to her own ideas about coconut oil.
