Joshua uses his thermometer and finds the boiling point of ethyl alcohol to be 75 degrees Celsius. He looks in a reference book and finds that the actual boiling point of ethyl alcohol is 80 degrees Celsius. What is his percent error?

Answers

Answer 1

Answer:

6.25%

Step-by-step explanation:

75 - 80 = -5

Absolute value of -5 is positive so -5 = 5

5 ÷ 80 = 0.0625 (1/16)

0.0625 × 100 = 6.25%

Joshua's percent error is 6.25%

Answers

Answer:

33 sq in

Step-by-step explanation:

≈ 64.43 cm²

Step-by-step explanation:

Subtract the area of the circle from the area of the rectangle.

area of rectangle = 7 × 11 = 77 cm²

area of circle = πr² = π × 2² = 4π cm²

Thus

area of shaded region = 77 - 4π ≈ 64.43 cm² ( to nearest hundredth )

[Please help]~granola bite contains 27 calories. Most of the calories come from c grams of carbohydrates. The rest come from other ingredients. One gram of carbohydrate contains 4 calories. The equation 4c + 5 = 27 represents the relationship between these quantities. What could the 5 represent in this situation?

Answers

Answer: calories from other ingredients

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

4c + 5 = 27

27 = calories contained in a granola bite

Most of the calories come from c grams of carbohydrates. The rest come from other ingredients. One gram of carbohydrate contains 4 calories.

So:

c = grams carbohydrates

4 = calories contained in 1 gram of carbohydrate

Since the sum of the product of the calories contained in 1 gram of carbohydrate (4) and the number of carbohydrates(c ); plus the calories from other ingredients is equal to the calories contained in a granola byte (27);

5 represents the calories from other ingredients

How does the graph of y = StartRoot x EndRoot + 2 compare to the graph of the parent square root function?
The graph is a horizontal shift of the parent function 2 units right.
The graph is a horizontal shift of the parent function 2 units left.
The graph is a vertical shift of the parent function 2 units up.
The graph is a vertical shift of the parent function 2 units down.

Answers

Answer:

The graph is a vertical shift of the parent function 2 units up.

Step-by-step explanation:

Our the function is:

y = √x + 2

Its parent function is: f(x) = √x

Answer:

The graph is a vertical shift of the parent function 2 units up.

Step-by-step explanation:

Our the function is:

y = √x + 2

Its parent function is: f(x) = √x

Then, the transformation can be rewritten as: f(x) + 2, which has the form f(x) + c, which is a vertical shift of f(x) c units up. Therefore, in this case, the parent function is shifted 2 units up.

This question is based on the concept of graph .Hence,the correct option is (c) i.e. the graph is a vertical shift of the parent function 2 units up.

Given:

The function of graph is [tex]\bold{y=\sqrt{x+2}}[/tex].

Its parent square root function is [tex]\bold{f(x)= \sqrt{x}}[/tex].

By the parent function we have to obtain given function ,So,we have to add on both  sides 2,

f(x)+2 = [tex]\sqrt{x+2}[/tex]

Thus, we have to added 2 to transform the parent root function into given function.Therefore, graph is shifted vertically 2 units up.

Hence,the correct option is (c) i.e. the graph is a vertical shift of the parent function 2 units up.

find the area of this figure

Answers

Answer: 49.12 ft²

Step-by-step explanation:

To find the area of this figure, we can separate it into 2 parts. We can find the area of the semi circle and the area of the triangle. Then we add together to areas.

Area of Triangle

A=bh/2

A=6(8)/2

A=48/2

A= 24 ft²

Area of Semi Circle

A=πr²/2  (Divide by 2 because semi circle is half of a circle, so we divide the area by 2)

A=π(4)²/2

A=(3.14)(16)/2

A=25.12 ft²

Total area

A=24+25.12=49.12 ft²

Step-by-step explanation:

Given

[tex]f(x) = 3x^3[/tex]

[tex]Domain = [2,5][/tex]

Find the Range

The range is calculated by solving for f(2) and f(5). In other words, the range is calculated when x is 2 and x is 5

When x = 2;

f(2) is as follows;

[tex]f(2) = 3*2^3[/tex]

[tex]f(2) = 3 * 8[/tex]

[tex]f(2) = 24[/tex]

When x = 5;

f(5) is as follows;

[tex]f(5) = 3*5^3[/tex]

[tex]f(5) = 3 * 125[/tex]

[tex]f(5) = 375[/tex]

Hence, the range of the function is [24, 375]

85<17m and 17m<136

For the first one,

Divide both sides by 17.

5<m

For the second one,

Divide both sides by 17.

m<8.

Therefore, 5<m and m<8. It is and not or because the compound inequality lists them together, not with an or separating it.
