Lucas built a composite solid by joining 12 identical blocks, with dimensions 4 inches by 5 inches by 7 inches, into three rows of four as shown.
12 blocks are in 3 rows of 4. Each block is 4 inches by 5 inches by 7 inches.
What is the total surface area of the composite solid?
521 square inches
1,042 square inches
1,072 square inches
1,992 square inches
Answers
Answer
the answer is b. im not sure though
Step-by-step explanation:
1042 square inches is the total surface area of composite solids.
It is clear from the image that the resulting composite solid is a cuboid.
whose sides are as follows
Across the length, there are 3 blocks along the side of 7 inches each.
[tex]Length = 7 \times 3 = 21\ inch[/tex]
Width = 5 inch
Across the height, there are 4 blocks along the side of 4 inches each.
[tex]Height = 4 \times 4 = 16\ inch[/tex]
What is the total surface area of a cuboid?[tex]\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)[/tex]
We know that the total surface area of a cuboid is,
[tex]\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)\Rightarrow 2 (21 \times 5 + 16 \times 21 + 16 \times 5 )\\\Rightarrow 2 (105 + 336+80)\\\Rightarrow 2 \times 521\\\Rightarrow 1024[/tex]
Therefore, the total surface area = 1024 square inches.

Accelerated students: Answer the above and make a line plot of the data.
Answers
Mean -
76+82+87+93+95+98 = 531
531/6 = 88.5
Range -
98 - 76 = 22
Median -
Because there are 6 numbers you have to find the average of the middle two
87+93 = 180
180/2 = 90
Mode -
No number is repeated so there is no mode.
Answer:
Mean: 88.5
Median:90
Mode:98
Step-by-step explanation:
For mean, what you need to do is add all of those numbers up and divide them by how many you have. So once you add up all those numbers, divide them by six because there are 6 numbers. For the median, order the numbers from smallest to biggest and cross off every one until you get left with the number in the middle. If there is an even number of numbers and there are two middle ones, add them together and divide them by 2. For mode, it’s the one with the most.

represents the change in the price of the stock over the week?
-20
-4
4
20
Answers
Answer:
-4
Step-by-step explanation:
so 4 would be negative because it decreased and 2 would be positive because it increased so multiply -4 by 3 wich is -12 then add it by 2 times 4 which is 8 and it is -4
The addition is one of the four fundamental mathematical operations. The correct option is B.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Given that the price of a stock decreased $4 per day for 3 days and increased $2 per day for 4 days. Therefore, The change in the price of the stock is,
Change in the price = (-$4 × 3 days) + (+$2 × 4 days)
= -$12 + $8
= -$4

Answer:
x = 20
y = 10
Step-by-step explanation:
Since we have a right triangle then:
sin(60) = 10√3/x ⇒ x = 10√(3)÷sin(60) = 20
cos(60) = y/20 ⇒ y = 20×cos(60) = 10
Answer:
Option B)
The value of x is 20 and y is 10
Step-by-step explanation:
Here, in a given right triangle
ΔABC, m∠B = 90°
Now,
tanθ = opposite ÷ adjacent
tan 60° = 10√3 ÷ y
√3 = 10√3 ÷ y
y = 10√3 ÷ √3
y = 10
Now,
sinθ = opposite ÷ hypotenuse
sin 60° = 10√3 ÷ x
√3 ÷ 2 = 10√3 ÷ x
√3 × x = 10√3 × 2
x = 20√3 ÷ √3
x = 20
Thus, The value of x is 20 and y is 10

A) 5x-7y=42
Step-by-step explanation:
We know that 5 x 7 = 35 then add 7 = 42
We divide 5 and 7 by 5/7
5/ 5/7 = 0.1
7/ 5/7 = 0.2
We find 0.1 = 1/10 and we know that 1/10 of 35 is 3.5
We find 0.2 = 2/10 and we know that 2/10 of 35 is 7 so the answer 7 matches.
We then use 7 for y and keep 5 for x.
