A box has a surface area of 450 cm². Its length and width are 6 and 8 respectively. What is its height?
Answer:
9.4 cm
Step-by-step explanation:
Given: Box; Length = 6 cm, Width = 8 cm, Surface area = 450 cm²
To Find: Height
Solution:
Divide the volume by the product of the length and width to calculate the height of a rectangular object.
6 × 8 = 48
450 ÷ 48 = 9.4
For this box, the rectangular object has a length of 6 cm, a width of 8 cm, and a volume of 450 cm². The product of 6 and 8 is 48, and 450 divided by 48 results in 9.4.
The height of the object is 9.4cm.

Answer:
This probaly sounds a little confusing
Step-by-step explanation:
1 day = 10 laps
1 lap = 400 meters
1 km = 1000 meters
12 km = ? days
We can use this information to find out a lot that we don't know.
HOW MANY METERS PER DAY??
In order to find the number of meters in a day, we think, "She ran 400 meters 10 times... 400 times 10... that's 4000 meters in one day."
1 day = 4000 meters (10 x 400 meters)
HOW MANY KILOMETERS PER DAY?
In order to find the number of km in a day, we can think, "One thousand is a kilo. There are 4 'one thousand's in 4000. Kali ran 4 kilometers (literally 4 thousand meters) per day.
1 day = 4 km (4000 m / 1000)
From here you can solve simply by thinking "How many 4km does it take to get to 12km?"
4 x ? = 12
? = 12 / 4
? = 3

The high temperatures for the last seven days are: High Temperatures: 81, 78, 83, 89, 80, 87, 78
Find the MODE of the temperatures.
Answer: 78
Step-by-step explanation:
The mode is the number that appears the most number of times. In this case the number 78 appears twice unlike the other numbers that only appear once. Hence, 78 is the mode :)
Answer:
78
Step-by-step explanation:
The mode is the value that appears most often in a set of data. The mode of a discrete probability distribution is the value x at which its probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.

y=2x+3 y=4x+7 solve by elimination
Answer:
[tex]\displaystyle [-2, -1][/tex]
Step-by-step explanation:
To use the Elimination method, you must get rid of one pair of variables, so that one side is set to zero. So, in this case, we must get rid of [tex]\displaystyle x,[/tex]therefore we will split the second equation in negative half :
[tex]\displaystyle \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}[y = 4x + 7]}} \right. \\ \\ \\ \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}y = -2x - 3\frac{1}{2}}} \right. \\ \\ \frac{1}{2}y = -\frac{1}{2}; -1 = y, -2 = x \\ \\ \\ \boxed{[-2, -1]}[/tex]

If p(x)=x^2+x+1 and Q(x)=5x^2-1, find the following
1. Q(4)
2.p(-4)
3.p(1/2)
Answer: 1. 79
2. 13
3. 7/4
Step-by-step explanation:
Q(x)=5x^2-1
Q(4)=5(4)^2-1
=5(16)-1
=80-1
Q(4) = 79
p(x)=x^2+x+1
p(-4)=(-4)^2+(-4)+1
=16-4+1
p(-4) =13
p(x)=x^2+x+1
p(1/2)=(1/2)^2+(1/2)+1
=1/4+1/2+1
2+4+8/9
=14/8
p(1/2) = 7/4
How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

Please help, Describe two methods that can be used to find the area of the composite figure.
Area of the composite figure can be find by using additive areas method and subtractive areas method
What is Composite figure?Composite geometric figures are made from two or more geometric figures. The composite figure below is made from parts of a rectangle and a circle
Since, Area is the quantity that expresses the extent of a region on the plane or on a curved surface.
Area of the composite figure can be find by using two methods,
Additive areas method and Subtractive areas method
In Addictive areas method
Break the composite shape into basic shapes
Find the area of the each basic shapes
Add all the areas of basic shapes together
In Subtractive areas method
Break the composite shape into basic shapes. That shape maybe larger than the composite shapes.
Find the area of the each basic shapes
Area of the composite shape will be the difference between the area of the larger shape.
Hence, the area of the composite figure can be find by using additive areas method and subtractive areas method

Answer: the answer is

Complete the table for the given rule.
Rule: y = 52
~Answer~
Substitute your numbers:
y = 5x
For the first one, y equals 5, so substitute 5 for y.
So, 5 = 5x.
What multiplied by 5 gives 5? The answer is 1.
So, the first one is 1.
Do the same for all the others.
So, 4 = 5x.
4 = 5(4/5)
As a decimal that equals 0.8.
For the last one, I can't tell if that is saying 2 or .2 so I'll do both.
for 2, you will do 2 = 5x and for .2, you will do .2 or 0.2 = 5x.
For 2, it would be 2/5 or 0.4.
For .2 or 0.2, it would be 0.04.
So,
x y
1 5
4/5 or 0.8 4
0.4 if it is 2 and 0.04 if it is 0.2. 2
(looking back, I'm pretty sure it was just 2 and not .2)
I hope this is what u were looking for, if not I'm so sorry for a useless answer. I wasn't completely sure whether I was doing it right since I haven't done these types of math problems in some time.

PLZZ HELP Me ASAP!!!!
Answer:
see explanation
Step-by-step explanation:
(a)
The area is calculated as length × breadth
area = 2x(2x + 6) ← distribute
= 4x² + 12x
(b)
area = x(x + 4) ← distribute
= x² + 4x
(c)
shaded area = 4x² + 12x - (x² + 4x)
= 4x² + 12x - x² - 4x ← collect like terms
= 3x² + 8x
