I’m going to assume the length is 10, width is 4, and height is 3
You would find the base of the rectangle which is the same as the top and that would be 80 (because 10 multiples by 4 for the base and top)
Then the ends which is 3x4= 12 and you have to sides so the total is 24
And lastly the sides which is 10x3= 30 and you have 2 sides so it’s really 60
In total you have 60+24+80= 164cm

Answers
Answer:
17
Step-by-step explanation:
Look at any 2 adjacent numbers and find the difference between them.
Starting with numbers 1 and 2, subtract the first from the second:
\(-7-(-15)=-7+15=8\)
That's a difference of 8, meaning the second number increased by 8.
Check the next numbers, 2 and 3:
\(1-(-7)=1+7=8\)
It increased by 8 again. Now that we know for sure that each term in the sequence increases by 8 over the previous one, we can find the number in the green box. Just add 8 to the number before it:
\(9+8=17\)
the rule is to add 8 to every next number

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.
Answers
We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:
0.80D = 0.24L
We are also given that the mass of the lion is 105 kg more than the mass of the dog:
L = D + 105
We can use these two equations to find the values of D and L.
Substituting the value of L from the second equation into the first equation:
0.80D = 0.24(D + 105)
Now, let's solve for D:
0.80D = 0.24D + 0.24(105)
0.80D - 0.24D = 25.2
0.56D = 25.2
D = 25.2 / 0.56
D ≈ 45
Now that we have the value of D, we can find the value of L by substituting it back into the second equation:
L = 45 + 105
L = 150
Therefore, the total mass of the dog and the lion is:
D + L = 45 + 150 = 195 kg
So, the total mass of the dog and the lion is 195 kg.

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units
The ratio of landline phones to cell phones at an apartment complex is 2 to 3. If there are 68 landline phones, how many phones are there in all at the apartment complex?
There are__nothing phones in all at the apartment complex.
HELP
Answers
Answer:
170.
Step-by-step explanation:
The number of cell phones = 68 * 3/2
= 102.
Total = 102 + 68
= 170 phones.
Using proportions, it is found that there are 170 phones in all at the apartment complex.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The ratio of landline phones to cell phones at an apartment complex is 2 to 3, hence 2/5 of all phones at the complex are landline phones.
There are 68 landline phones in the complex, hence:
2/5n = 68.
n = (68 x 5)/2
n = 170.
