Answer:
Volume
Figure 1 = 56 cube units
figure 2 = 60 cube units
figure 3 =72 cube units
Surface area
Figure 1 = 100 square units
figure 2 = 104 square units
figure 3 =108 square units
Step-by-step explanation:
From the all figure we can see that each figure made up of unit cubes
<u>Figure 1</u>
<u>Surface area </u>
Large cuboid portion =2 x (6 x 2 ) + (6 x 4) + 2 x(4 x 2) + 16
= 24 + 24 + 16 + 16 = 80 unit square
Small cuboid portion = (4 x 2) + (2 x 2) + (4 x 2) = 8 + 4 + 8 = 20
Total surface area = 80 + 20 = 100 unit square
<u>Volume</u>
Small cuboid = 4 x 2 = 8
Large cuboid = 6 x 4 x 2 = 48 cube unit
Total volume = 48 + 8 = 56 cubs units
<u>Figure 2</u>
<u>Surface area </u>
Total surface area =24 + 18 + 36 + 20 + 6 = 104 unit square
<u>Volume</u>
Small cuboid = 6 x 2 = 12
Large cuboid = 6 x 4 x 2 = 48 unit square
Total volume = 48 + 12 = 60 cube units
<u>Figure 3</u>
<u>Surface area </u>
Total surface area = 48 + 36 + 24 = 108 square units
<u>Volume</u>
Total volume = 6 x 4 x 3 = 72 cube units
Answer:
At Irtaza's Deli
Step-by-step explanation:
For this you should find the unit price and whichever is less is where you should go.
<em><u>(1) Irtaza Deli:</u></em>
First I would round the 5.99 to 6 then we'll do 6 divided by 7.
<em><u>(2) Brianna's Food Mart:</u></em>
First I would round the 8.99 to 9 then we'll do 9 divided by 10.
<em><u>Now let's compare:</u></em>
So the first store sells oranges for $.86 and the second store sells them for $.90. I don't know about you but I would go to the first store they would be much more cheaper.
I know this wont help but y=mx+c or +b will need to be used so y will equal to 3x+5 so the equasion is y=3x+5
sorry, thats all i can do
Answer:
x=5
Step-by-step explanation:
set up the equation like this: JK+KL=JL
(15)+(10)=(5x)
calculate to find x!
x=5
Answer:
x = 6
a = 18 ft
b = 36 ft
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
- Factoring/Expanding
- Solving quadratics
<u>Trigonometry</u>
- Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
Given: Right triangle
a = 3x
b = 6x
c = 40
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: (3x)² + (6x)² = 40²
- Evaluate: 9x² + 36x² = 1600
- Combine like terms: 45x² = 1600
- Isolate <em>x </em>term: x² = 320/9
- Isolate <em>x</em>: x = (±8√5)/3
- Evaluate: x = ±5.96285
Since it is not a quadrant triangle, we must use the positive value for <em>x</em>.
<u>Step 3: Find legs</u>
Leg a
- Define: 3x
- Substitute: 3(5.96285)
- Multiply: 17.8885
- Round: 18
Leg b
- Define: 6x
- Substitute: 6(5.96285)
- Multiply: 35.7771
- Round: 36
