2 models divided into 100 parts. Left: 68 are shaded gray. Right: 68 are shaded gray.
=====================================================
Explanation:
Consider the problem of 0.68 of 1, in other words 0.68*1 or simply 0.68
The number 0.68 is 68/100 or 68 over 100. We can have a 10 by 10 grid of tiny squares. Shade in 68 of them to represent 0.68 aka 68 hundredths.
So you'd have 6 full rows shaded (to account for 0.60 so far) and then an additional 8 squares in the seventh row (adding on 0.08 to get 0.60+0.08 = 0.68)
All of this is for one square. Double this process and you'd get 0.68*2 to represent the value 1.36
In total, 2*68 = 136 squares are shaded out of 2*100 = 200 squares total.

This figure represents a small weight that is to be covered on all sides with a floral fabric. How much fabric is needed to cover the weight? Enter your answer as a decimal in the box.
Answer:
77.5 cm²
Step-by-step explanation:
We need to find the surface area of the rectangular prism.
Total surface area = 2(lw + wh + lh)
where:
l = length of basew = width of baseh = height of prismGiven dimensions:
[tex]\textsf{length}=\sf 6\dfrac12\:cm=6.5\:cm[/tex]
[tex]\textsf{width}=\sf 2\dfrac12\:cm=2.5\:cm[/tex]
[tex]\textsf{height}=\sf 2\dfrac12\:cm=2.5\:cm[/tex]
Substituting these value into the formula:
[tex]\begin{aligned}\textsf{Surface area} & =\sf 2(6.5 \cdot 2.5+2.5 \cdot 2.5+6.5 \cdot 2.5)\\ & = \sf2(16.25+6.25+16.25)\\ & = \sf 2(38.75)\\ & =\sf77.5\:cm^2 \end{aligned}[/tex]
Therefore, 77.5 cm² of fabric is needed to cover the weight.
If [tex]$l$[/tex] be the length of cuboid, [tex]$b$[/tex] be the breadth of cuboid and [tex]$h$[/tex] be the height of cuboid, then its total surface area (TSA) of cuboid is given by,
[tex]\;\longrightarrow\boxed{\tt{TSA = 2(lb + bh + lh)}}[/tex]
A cuboid is also known as rectangular prism.
Elucidation:We need to find the surface area of the cuboid or rectangular prism whose length, breadth and height are given.
Length = 6 1/2 = 6.5cmBreadth = 2 1/2 = 2.5cmHeight = 2 2/2 = 2.5cmNow by using the formula of surface area nd substituting the given values, we get the following results:
[tex]\implies\tt{Surface\;area = 2(6.5 \times 2.5 + 2.5 \times 2.5 + 6.5 \times 2.5)}\\[/tex]
[tex]\implies\tt{Surface\;area = 2(16.25 + 6.25 + 16.25)}\\[/tex]
[tex]\implies\tt{Surface\;area = 2(38.75)}\\[/tex]
[tex]\implies\boxed{\pmb{\tt{Surface\;area = 77.5}}}\\[/tex]
Hence, this is our required solution for this question.

HELP ME PLEASE
b) Your sister says that the angles ∠DCA and ∠BCA are supplementary angles. Is she correct? Explain your reasoning. (1 point)
c) Is triangle DCA congruent to triangle BCA? Explain. (2 points)
Answer:
B) No, supplementary angles are either of two angles whose sum is 180 degrees.
C) Yes, the triangles are congruent because the triangles have exactly the same size and shape
Step-by-step explanation:
B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.
C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.
The number j increased by 4 I NEED IT IN A EXPRESSION (it's not 2y+4)
Can you please help me understand this concept?
Step-by-step explanation:
It is an equal step by step equation because the prism has equal sides, so you would just have to add all them up and too try to find the surface area, and you know how the bottom is ten so the top would be ten too.

Find the area of the circle. Round your answer to two decimal places, if necessary.
Answer:
A≈50.27
Step-by-step explanation:
The formula for an Area of a circle is: A=πr(squared)
As was can the the diametter is 4, and the radius is half of the diameter, making the radius half of 4 whitch is 2. now just plug in two for R.
A= π4(squared)
4(squared) = 16
A= 16π
A= 50.27
write an expression to represent the area of the flag as the product of the flags length and width
Answer:
A = l * w
Step-by-step explanation:
the length times width would be the area, so just make variables of each thing and then you are good! It would be important to note any more information that is given, like the ratio of the length and the width, in which case just add the respective coefficients based on the ratio (e.g 3:2 would mean 3l * 2w = A). Hope this helps!
Peyton and James each bought a large cookie cake. The cookie cakes are
the same size.
Peyton cut his cookie cake into 12 slices.
James cut his cookie cake into 6 slices and ate 4 slices.
Together Peyton and James ate 10
12 of one cookie cake.
How many slices of cake did Peyton eat?
A 1 slice
B 2 slices
C 3 slices
D 4 slices
Answer:
2 slices.
Step-by-step explanation:
Let's say that James' cake is essentially one half of Peyton's cake. 6 x 2 is 12, and 4 x 2 is 8. So James' must have eaten 8 slices while Peyton ate 2.

7 Points: What is the volume of this rectangular pyramid?
_______ cubic yards
Answer:
25 cubic yardsStep-by-step explanation:
[tex]\large\text{volume of a rectangular pyramid} =\frac{1}{3} \times \text{base} \times \text{height}[/tex]
[tex]=\frac{1}{3} \times \left( 5\times 5\right) \times 3[/tex]
[tex]=\frac{1}{3} \times \left( 25\right) \times 3[/tex]
[tex]=\frac{1}{3} \times \left( 75\right) =\frac{75}{3} =25[/tex]
Answer:
5 yards
Step-by-step explanation:
The volume V of a pyramid is one-third the area of the base B times the height h .
[tex]volume \: = \frac{1}{3} \times base \times height[/tex]

Hello PLS HELP.................
Write the equation of a line that passes through the point (–10, 2) that has a slope of .5
Answer:
y=(.5)x+7
Step-by-step explanation:
Hello. For this question, they are asking us to find the equation of a line. A line has this form: y=mx+b.
For this question they will want us to give the answer with x and y as variables (letters) and m and b (the slope and y-intercept respectivly) with numerical values.
First, we can put in the point into the equation. The point given is (-10,2) so the x value is -10 and they y value is 2.
y=mx+b
2=m(-10)+b
Then we know that the slope is .5, so we can put that in as m.
2=(.5)(-10)+b
Solving for b, we get that it is equal to 7.
[2+5=b] b=7
Therefore, the equation for the line would be:
y=(.5)x+7
