Answer:

They are not equivalent

Step-by-step explanation:

2(x+4)+4

First you distribute the 2.

2x+8+4

Then combine like terms

2x+12

Therefore they are not equivalent

Let's go through each answer.

A.

Answer: The amount left over was 4.05 L.

Estimation: 3.15 + 4.75 is about 7.

7 L – 4 L = 3 L

The amount left over was about 3 L.

This is incorrect because 3.15+4.75 is closer to 8 than 7.

B.

Answer: The amount left over was 3.95 L.

Estimation: 3.15 + 4.75 is about 8.

8 L – 4 L = 4 L

The amount left over was a little less than 4 L.

This is correct because 3.15+4.75 is close to 8 and to find the amount left over you do have to subtract.

The correct answer is B.

Answer: The amount left over was 3.95 L.

Estimation: 3.15 + 4.75 is about 8.

8 L – 4 L = 4 L

The amount left over was a little less than 4 L.

Second Option

Step-by-step explanation:

Answer:

[tex]\boxed{15}[/tex]

Step-by-step explanation:

First using the Pythagorean theorem, we know the hypotenuse [tex](c^2)[/tex] is  39 and one of the legs [tex](b^2)[/tex] is 36. So we would have:

[tex]a^2+36^2=39^2=a^2+1296=1521\\\text{Subtract 1296 on both sides:}\\a^2=225\\\text{find the square root of 225}\\\sqrt{225}=15[/tex]

So we have our answer as [tex]\boxed{15}[/tex]

Hope this helps.

Answer:

by using Pythagoras law

p²+b²=h²

p²+36²=39²

p²=39²-36²=225

p=√225=15

Answer:  2184

Step-by-step explanation:

1lb = 16oz

6.5lb (16oz/1lb) = 104 oz

which means its 104 oz of ham uses in each day.

7 days in a week, then  3 weeks means 3 x 7 = 21 days

104oz in a day, 21 days (3 weeks) equals 21 x 104 = 2184 oz

Answer:

38

Step-by-step explanation

2/7× 133=38

Answer:

56°

Step-by-step explanation:

the question tells us the 2 triangles are similar, thus the angoes are identical on the 2 triangles. with this right triangle, you can see there is a long leg, short leg, and the hypotenuse. in order to solve this, you need to find the angle on the first triangle that corresponds to the second triangle. in this case, we can conclude angle K corresponds to angle E because the angles are adjacent to the long leg and hypotenuse, and opposite to the short leg.

Answer:

the properties of classification, order, equal distance, and unique origin.

Step-by-step explanation:

A level of measurement refers to a classification which is used to illustrate the attributes of the values assigned to variables. Basically, there are four (4) levels of measurement for a variable and these are;

1. Ratio: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.

2. Nominal: is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.

3. Interval: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.

4. Ordinal: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.

Hence, a ratio scale contains the properties of classification, order, equal distance, and unique origin.
