Davis has a thin box that is 5 inches wide. He wants to use the box to store markers that are 1/2 inch wide. If he lines up the markers side by side and uses the entire width of the box, how many markers can Davis fit in the box?
Answer:
10
Step-by-step explanation:
Given that :
Width of box, W = 5 inches
Width of marker to be stored in box = 1/2 inch
The number of 1/2 inch marker which can be stored in box is :
Width of box ÷ width of marker to be stored in box
5 inches ÷ 1/2 inches
5 / 0.5
= 10
Hence, Ten 1/2-inch width marker can be stored in the box

What is the length of the missing leg?
Answer:
6
Step-by-step explanation:
[tex]\sqrt{10^{2} -8^{2} }[/tex] = 6
Answer:
b = 6
Step-by-step explanation:
Pythagorean formula:
a² + b² = c²
Work:
a² + b² = c²
8² + b² = 10²
64 + b² = 100
b² = 100 - 64
b² = 36

Henry is mixing concrete.
To make concrete he needs to mix cement, sand and gravel in the ratio 3 : 2 : 7 by weight.
Henry needs to make 180kg of concrete.
He has 46kg of cement, 29kg of sand and 105kg of gravel.
Which ingredient is Henry short of?
9514 1404 393
Answer:
1 kg of sand
Step-by-step explanation:
For 180 kg of concrete using the given ratios, you need ...
(3/12)(180 kg) = 45 kg of cement
(2/12)(180 kg) = 30 kg of sand
(7/12)(180 kg) = 105 kg of gravel
The inventory of 29 kg of sand is 1 kg short of the amount needed.
Henry is short 1 kg of sand.

Step Three
Patterns can be defined as the sequence or arrangements which numbers follow.
The number of small squares that are in Step 10 is 110 small squares.
From the question,
Step one : • • = 1(2) small squares
Step two : • • • = 3 squares in two layers = 2(3) = 6 small squares
• • •
Step three : • • • • = 4 squares in 3 layers = 3(4) = 12 small squares
• • • •
• • • •
Let the number of steps we are to find be represented by = s
Hence, from the above pattern, the formula is given as:
Number of small squares = n x (1 + n)
Therefore, using the formula from the pattern, the number of small squares that are in Step 10 is calculated as:
10 x (1 + 10)
= 10 x 11
= 110 small squares.

Michael has $68. Craig has $24 less than Michael has. Michael spends $20 on a new hat. Michael has $68. Craig has $24 less than Michael has. Michael spends $20 on a new hat. Write an equation where the solution represents the amount of money (x), in dollars, craig has after michael buys the hat. Explain how you came to this equation.
Answer:
X + 4 = 48
Step-by-step explanation:
Before hat purchase :
Michael has $68
Craig has $24 less than Michael;
Hence, Craig = $68 - $24 = $44
Michael purchased hat worth, $20
x = amount Craig has after Michael purchase hat:
x = Amount Michael has - $24
Amount Michael has after hat purchase = $68 - $20 = $48
x + 4 = 44 + 4
X + 4 = 48

Which of the following equations corresponds to the graph below
Answer:
d) y = -1/2 + 3
Step-by-step explanation:
Looking at the graph, we can use y = mx + b to find the equation. m is the slope and for slope, we go 1 unit down and 2 units to the right. b is the y variable and our b would be 3.
y = mx + b
y = -1/2x + 3

Clay works on a farm. He packaged eggs into
containers that hold 1 dozen eggs each. He filled
4 containers with white eggs and 5 containers
with brown eggs. How many eggs did Clay
collect? Hint: one dozen eggs = 12 eggs
Answer:
(4×12)+(5×12)
48+60
108 eggs total
Answer:
108
Step-by-step explanation:
Well considering the fact that the question is asking how many eggs did Clay collect in total, we can just multiply 4*12 (12 being how many eggs being in the container and 4 being the amount of containers) and multiply 5*12 to get a total of 108 eggs. Or you could just add both the amount of containers and multiply it by 12. Hope this helped :)
What is the kinetic energy of a 4 kg cart pushed at a rate of 0.5 m/s?
A. 0.5J
B. 2J
C. 4J
D. 8J
Answer:
A. 0.5J
Step-by-step explanation:
[tex]K. E._{(cart)} = \frac{1}{2} m {v}^{2} \\ \\K. E._{(cart)} = \frac{1}{2} \times 4 \times (0.5)^{2} \\ \\ K. E._{(cart)} = 2 \times 0.25 \\ \\ K. E._{(cart)} = 0.5 \: J[/tex]
The kinetic energy of a 4 kg cart pushed at a rate of 0.5 m/s is 0.5 J.
Kinetic energy = 1 /2 mv²
where
m = mass
v = velocity
Therefore,
m = 4 kg
v = 0.5
Kinetic energy = 1 / 2 × 4 × 0.5²
kinetic energy = 1 / 2 × 4 × 0.25
kinetic energy = 1 / 2 × 1
kinetic energy = 1 /2 = 0.5 j

Marta has 7 more than half as many books as Lucy. If L is the number of books Lucy has, which expression could be used to find the number of books Marta has?
Answer: L/2 + 7
Step-by-step explanation:
Number of books that Lucy has = L
Since Marta has 7 more than half as many books as Lucy, the expression that could be used to find the number of books Marta has will be gotten by multiplying the number of books that Marta has by 1/2 and then adding 7 to the value gotten. This will be:
= (1/2 × L) + 7
= L/2 + 7 or 0.5L + 7
