Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains.

If he has 2 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?

Glenn needs
pieces.

Answers

Answer 1
He can cut 20 1-meter pieces since 1 decametre is equal to 10 meters. So you divide 20 meters by 1 which will give you 20 pieces.

1 decametre = 10 meters
2 decametres = 10 meters x 2
= 20 meters
Answer 2

Answer: 20

Step-by-step explanation:  1 decameter has 10 meters so if he has 2 decameter long ribbons than it would be 20 meters.

Q: Find the surface area to the nearest tenth←

Answers

Answer:

119.0 cm²

Step-by-step explanation:

What is surface area

It is the area of the outside part of anything. Surface area is also called total surface area.

As we can see from the pyramid, it has a square base. How do I know that it is a square base, is by seeing the dimensions of the base, which are 6.4 cm by 6.4 cm in this pyramid. And we already know from basic Geometry that a square has 4 equal sides. So we call it a square pyramid.

So to find the total surface area of this square pyramid, we need the area of the 4 triangular faces and the area of the square base.

So t.s.a of the pyramid = 4 × Area of each triangular face + Area of the square base.

So, total surface area = Area of square base + Area of the four triangular faces.

     total surface area = (length²) + (4 × [tex]\frac{1}{2}[/tex] × base × height)

     total surface area = (6.4 × 6.4) + (4 × [tex]\frac{1}{2}[/tex] × 6.4 × 6.1)

     total surface area = 40.96 + 78.08

     total surface area = 119.04 cm² ≈ 119.0 cm² (to the nearest tenth) (Answer)

119.0cm^2

So t.s.a of the pyramid = 4 × Area of each
triangular face + Area of the square base.
So, total surface area = Area of square base +
Area of the four triangular faces.
total surface area = (length?) + (4 × ;
× base × height)
total surface area = (6.4 x 6.4) + (4 x = x
6.4 x 6.1)
total surface area = 40.96 + 78.08
total surface area = 119.04 cm^2 ~ 119.0 cm^2

Answer:

Congruent Sides- Rectangle, Rhombus, Square

Right Angles- Rectangle, Square

Both- Rectangle, Square

Step-by-step explanation:

Rectangle- Rectangles always have congruent sides and right angles

Rhombus- A rhombus is a parallelogram which makes it congruent but it does not have a right angle

Square- A square has both congruent sides and right angles every time as it is equal and straight on every side

Answer:

4 congruent sides- rhombus

4 right angles- rectangle

Simplify:

We know that negative times negative equals positive, therefore:

[tex]\displaystyle \large{|x+12| \quad (x < -12)}[/tex]

Modulus Property:

[tex]\displaystyle \large{|x+a| = \begin{cases} x+a \quad (x \geq -a) \\ -x-a \quad (x < -a) \end{cases}}[/tex]

Therefore, since given interval is x < -12:

A. h ≥ 16

B. h ≤ 16

C. h ≥ 30

D. h ≤ 30

Answers

Answer:

B

Step-by-step explanation:

this is because she is only making less than or equal to 16 hotdogs, which the sigh indicates in answer B

Answer:

B

Step-by-step explanation:

It will be letter B because when it says at most it would be equal to 16 or less than 16 so, therefore, it will be letter B. The answer will not be for the burgers because since it says she plans to cook 30 burgers and not at most or at least it would mean that the answer will be either A or B.

Option A is right

Step-by-step explanation:

In any data set, we find that the range is the difference between maximum and minimum.  The range cannot give full information about the variability of the data set.

Outliers are the ones which are either below Q1-1.5IQR or Q3+1.5IQR

Thus Inter quartile range, the difference between I quartile and III quartile gives a better idea about variability and also outlier.

Hence out of the four options given, we find that option B is the right one.

Step-by-step explanation:

Mean: Add all of the values together and divide by 8 (the number of values). This is also called average.

Median: The middle value when ranked lowest to highest. In this case there are an even number of values (8), so you have to use the average of the middle two, which are 12 and 15.

Mode: This is the most commonly appearing value, and in this case 21 is the only value that appears twice.

Midrange: To find this you add the highest and lowest values together and divide by two. In this case, those values are 5 and 21.

how to solve and answer for 4 1/3 - 2 1/5 ?

Answers

Answer : 2 2/15


To begin you need to convert the fractions into something they both can go into. Sometimes it is easier to multiple the two denominator of the fractions, which in this case it is.
So, 3 times 5 is 15
This means your going to convert your fraction into 15th

1/3 is 5/15
This is because you need to times the bottom by 5 in order to get 15, so you need to do the same with the top.

1/5 is 3/15
This is because you need to times the bottom by 3 to get 15 so you do the same with the top

Next you just subtract the amounts separately
4-2 = 2
5/15 - 3/15 = 2/15

This means your answer is 2 2/15

Answer:

2 2/15 or if you want it in decimal form it's 2.133
