What is mean by Cuboid?A cuboid is the solid shape or three-dimensional shape. A convex polyhedron which is bounded by six rectangular faces with eight vertices and twelve edges is called cuboid.
We have to given that;
For large rectangular prism,
Lenght = 24
Width = 16
Height = 8
And, For small rectangular prism,
Lenght = 15
Width = 10
Height = 5
Hence, the surface areas of the large rectangular prisms is,
⇒ SA = 2lw + 2lh + 2hw
⇒ SA = 2 (24 x 16 + 24 x 8 + 8 x 16)
⇒ SA = 2 (384 + 192 + 128)
⇒ SA = 2 (704)
⇒ SA = 1408
the surface areas of the small rectangular prisms is,
⇒ SA = 2lw + 2lh + 2hw
⇒ SA = 2 (15 x 10 + 15 x 5 + 10 x 5)
⇒ SA = 2 (150 + 75 + 50)
⇒ SA = 2 (275)
⇒ SA = 550
Hence, The value of the ratio for the surface areas of the rectangular prisms is,
⇒ 1408 : 550
⇒ 704 : 275

Solve 2(x + 1) = 2x + 5. All real numbers No solution 0 3
Answers
Answer: No solution 0=3
Step-by-step explanation:
2(x+1)=2x+5
Step 1: Simplify both sides of the equation.
2(x+1)=2x+5
(2)(x)+(2)(1)=2x+5(Distribute)
2x+2=2x+5
Step 2: Subtract 2x from both sides.
2x+2−2x=2x+5−2x
2=5
Step 3: Subtract 2 from both sides.

in order to make some extra money in the summer you water your neighbors lawn and walk their dog.your neighbor pays you $5 each time you walk the dog and $6 each time you water the lawn . when you do both jobs on the same day she gives you an extra $3 , on june 1, you dont have to complete either job, because your neighbor did them bith the day before . if you worked for your neighbor from june 1 to july 20 (thre are 30 days in june and 31 days in july), how many times would you do both jobs on the same day? How much in total would you earn from your neighbor from june 1 to July 20th?
Answers
Complete question :
In order to make some extra money in the summer, you water your neighbor's lawn and walk their dog. You water their lawn every 6 days and walk the dog every 4 days. Your neighbor pays you $5 each time you walk the dog and $6 each time you water the lawn.When you do both jobs on the same day. she gives you an exrta $3. On june 1, you dont have ro complete either job, because your neighbor did them both the day before. if you worked for your neighbor from june 1 to july 20 ( there 30 days in june and 31 days in july ), how many times would you do both jobs on the same day ? how much total money would earn?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Watering lawn (L) = $6
Walking a dog (D) = $5
Watering lawn and walking a dog = $(6+5+3) = $14
Lawn is watered every 6 days
Dog is walked every 4 days
Working between June 1 to July 31st:
Last time neighbor did both chores = may 30
how many times would you do both jobs on the same day?
Both jobs were done 4 times on the same day between June 1 to July 30
How much in total would you earn from your neighbor from june 1 to July 20th?
Dog walk = (8 * $5) = $40
Watering lawn = (4 * $6) = $24
Both chores = (4 * $14) = $56
$(40 + 24 + 56) = $120

STEP 3 :
Rewriting the whole as an Equivalent Fraction
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 2 as the denominator :
7 7 • 2
7 = — = —————
1 2
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
m-14
———— • 2 = 0 • 2
2
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
m-14 = 0
Solving a Single Variable Equation:
4.2 Solve : m-14 = 0
Add 14 to both sides of the equation :
m = 14
One solution was found :
m = 14

Step-by-step explanation:
Given
[tex]Initial\ Height =25[/tex]
[tex]Rebound = \frac{4}{5}[/tex]
Required
Determine the height at the third rebound
At first rebound;
[tex]H1 = 25 * \frac{4}{5}[/tex]
Second rebound
[tex]H2 = 25 * \frac{4}{5}* \frac{4}{5}[/tex]
Third rebound
[tex]H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}[/tex]
Hence; the equation is:
[tex]H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}[/tex]
Solving further;
[tex]H3 = 12.8\ ft[/tex]
