Are the Triangle similar? Why or why not?

Answers

Answer 1

Answer:

No, they are not similar

Step-by-step explanation:

The three triangle angles should always add up to 180 degrees.

In the smaller triangle, one angle is 90 degrees, so the other 2 angles in that triangle will equal 90 when added.

In the bigger triangle, the 2 other angles are 60 & 70 degrees, amounting to 130 degrees. This means the last angle will be 50 degrees.

In the end, these two triangle are NOT similar because one has a right angle and the other doesn't.

Answers

There’s 16 ounces in a pound
135.5 • 16
Answer is 2,184 ounces of ham will be used in 3 weeks

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

Answers

Answer:

In my opinion i would think A but it might be P also, sorry im not sure but thats my best guess.

Step-by-step explanation:

Figure 4 has rotational symmetry but no line symmetry.

Option D is correct.

Symmetry :

The rotational symmetry of a shape explains that when an object is rotated on its own axis, the shape of the object looks the same.

Some of the examples are square, circle, hexagon.A line of symmetry is a line that cuts a shape exactly in half. It means that if we fold the shape along the line, both halves would match exactly.

From given figure, It is observed that figure 4 has rotational symmetry but no line symmetry.

A ratio scale contains _____. the properties of order, classification, and equal distance between points but no unique origin the four major sources of error mutually exclusive and collectively exhaustive categories as well as the property of order, but not distance or unique origin the properties of classification, order, equal distance, and unique origin mutually exclusive and collectively exhaustive categories, but without the properties of order, distance, and origin

Answers

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.

Sofia mixed 3.15 L of grape juice with 4.75 L of cranberry juice. Her friends drank 3.95 L of the juice mixture.

How much juice was left over?

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.

Answer: The amount left over was 11.85 L.
Estimation: 3.15 + 4.75 is about 8 L.
8 L + 4 L = 12 L.
The amount left over was a little less than 12 L.

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.

Answers

Let's go through each answer.

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.

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.

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

The probability of rolling a number cube and getting a 6 and 3.

Answers

We have to find out the probability of getting 6 and 3,

Since this only one roll it is not possible to get 2 numbers in one roll

So, I will presume you want the probability of getting 6 or 3,

Total number of outcomes= {1,2,3,4,5,6} = 6 outcomes

Number of favorable outcomes = {3,6} = 2 outcomes

Probability of rolling 6 or 3 = [tex]\frac{Number'of 'favorable' outcomes}{Total' number 'of' outcomes}[/tex]

= 2/6

= 1/3 or 0.33333%

Therefore the probability of rolling 6 or 3 is one in three chances
