The surface area the cuboid is 142 inches²
The surface area of the cuboid is given as:
= 2lw + 2lh + 2hw
where, l = length
h = height
w = width
Therefore, the surface area of the cuboid given will be:
= 2lw + 2lh + 2hw
= 2(7×3) + 2(7 × 5) + 2(3 × 5)
= 2(21) + 2(35) + 2(15)
= 42in + 70in + 30in

The domain of a quadratic is all real numbers.
a) True
b) False
Answer:
Step-by-step explanation:
I'd be very hesitant to say true.
If the quadratic is in the form of y = x^2 then the statement is correct. The entire family all have a domain of all the real numbers.
However if the quadratic is of the form x=y^2 then the starting point of this quadratic is (0,0). All of these quadratics have a different starting point. \\
Since you have not specified the kind of quadratic, the answer is not always true.

ABC is a right triangle. If AC=4 and BC=10, find AB. Leave your answer is the simplest radical form.
Answer:
√116 or √84Step-by-step explanation:
ABC is a right triangle
AC=4, BC=10, AB = ?Here we have two options:
1. AB is hypotenuse, then:
AB = [tex]\sqrt{AC^2 + BC^2} = \sqrt{4^2 + 10^2} = \sqrt{16 + 100} =\sqrt{116}[/tex]2. BC is hypotenuse and AB is the second leg, then:
AB = [tex]\sqrt{BC^2 - AC^2} = \sqrt{10^2 - 4^2} = \sqrt{100 - 16} = \sqrt{84}[/tex]Hummingbirds have unusually large hearts for their body size. If a person's heart were as
big as a hummingbird's, his or her heart would weigh as much as a large dog.
Information you will need:
An average hummingbird weighs 0.3524 ounces and has a heart that weighs 0.00875
ounces.
1 pound = 16 ounces
The average weight of a large dog is usually more than 80 pounds.
Leo weighs 192 pounds.
a.) How much would Leo's heart weigh if it were the same ratio as a hummingbird's?
Show your work on your paper.
b.) is the original claim true or false? Justify your reasoning here along with your answer.
Answer: 4.8lbs, This claim is false
Step-by-step explanation:
Leo weighs 192 pounds. Then Leo's heart weight will be 76.258 ounces. So, its claim is false.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
Hummingbirds have abnormally huge hearts for their body size. In the event that an individual's heart was essentially as large as a hummingbird's, their heart would weigh as much as an enormous canine's. A typical hummingbird weighs 0.3524 ounces and has a heart that weighs 0.00875 ounces.
The ratio of heart to weight is given as,
Ratio = 0.00875 / 0.3524
Ratio = 0.024829
The average weight of a large dog is usually more than 80 pounds. Leo weighs 192 pounds. Then Leo's heart weight is calculated as,
⇒ 0.024829 x 192 x 16
⇒ 76.28 ounces
Their heart weight of Leo is less than the weight of the dog. So, its claim is false.

In rhombus CATS, CA= 6x-30. AT= 2x+30 find the perimeter? I need help ASAP PLEASE
Length of CA = 6x - 30
Length of AT = 2x + 30
We know that all sides of a rhombus are congruent.
Which means :
[tex] = 6x - 30 = 2x + 30[/tex]
[tex] = 6x - 30 - 2x = 30[/tex]
[tex] = 4x - 30 = 30[/tex]
[tex] = 4x = 30 + 30[/tex]
[tex] = 4x = 60[/tex]
[tex] = x = \frac{60}{4} [/tex]
[tex] = x = 15[/tex]
Thus, the value of x = 15
Then :
Measure of CA :
[tex] = 6x - 30[/tex]
[tex] = 6 \times 15 - 30[/tex]
[tex] = 90 - 30[/tex]
[tex] = 60[/tex]
Thus, measure of CA = 60
Measure of AT :
[tex] = 2x + 30[/tex]
[tex] = 2 \times 15 + 30[/tex]
[tex] = 30 + 30[/tex]
[tex] = 60[/tex]
Thus, measure of AT = 60
Perimefer of rhombus CAT :
[tex] = 4 \times side[/tex]
[tex] = 4 \times 60[/tex]
[tex] = \color{plum}240[/tex]
Therefore, the perimeter of rhombus CAT = 240

Find the surface area

40 feet tall and 20 feet
across the base.
square feet
Do NOT round your answer.
Answer:
the surface area is 3140 square feet
Step-by-step explanation:
The computation of the surface area is given below:
Given that
Diameter = 20 feet
radius = 20 ÷ 2 = 10 feet
Surface area = [tex]2\pi r^2 + 2\pi rh[/tex]
= 2 × 3.14 × (10)^2 + 2 × 3.14 × 10 × 40
= 6.28 × 100 + 6.28 × 400
= 628 + 25.12 × 100
= 628+ 2512
= 3140 square feet
hence, the surface area is 3140 square feet

The formula for the gravitational potential energy of an object is U = mgh, where U represents the potential energy, m represents the mass of the object, g represents the acceleration due to gravity, and h represents the object’s height above the ground. Solve this formula for h.
U=mgh
U/m=gh
U/mg=h
therefore:
h=U/mg
The solution for h is h = U / (mg),
where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.
Here, we have,
To solve the formula U = mgh for h (the height above the ground),
we need to isolate h on one side of the equation.
Here are the steps:
Start by dividing both sides of the equation by mg:
U / (mg) = (mgh) / (mg)
This simplifies to:
U / (mg) = h
Now we have isolated h on one side of the equation.
Therefore, the formula for h is:
h = U / (mg)
So, the solution for h is h = U / (mg),
where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.

What is the value of x?
A student said that x = 4 was not a solution to the question 3(x -6) = -8
Here is their work:
3(x -6) = -8
3 (4 -6) = -8
12 -6 = -8
6≠ -8
so x = 4 is not a solution
Did the student substitute x=4 correctly? How do you know?
Did the student simplify with Order of Operations correctly? How do you know?
If you try the problem, what do you get when you substitute x=4 into the equation?
Answer:
Step-by-step explanation:
3 (4 -6) = -8 is correct. The next step is to combine 4 and -6, obtaining
3(-2)
and this 3(-2) should equal -6, which is not the same as -8.
3(4 - 6) = 12 - 18, which differs from the student's solution. This is the reason for the wrong answer.

Answer: Part A. B origin Part B. C(0,0)
Step-by-step explanation:
In a coordinate plane, there are two axes
1) x-axis which is the horizontal axis.
2) y-axis which is the vertical axis.
The intersection of both the axes is known as the origin whose coordiantes are (0,0), i.e. at this point value of x =0 and value of y =0.
Part A: The ordered pair that represents the intersection of the x-axis and y-axis is called the origin.
Part B: The coordinate. Part B the coordinates of the origin are (0,0).
