Hi!
Got a question!
Rectangular container holds 70 litres of water when full. Its height is 70 cm.What is its base area?
Thanks!!
And please explain!
Answer:
1000cm^3
Step-by-step explanation:
capacity=base area times height, convert litres to cm^3,1000cm^3=1l,equate Base area=capacity/height (70000/70)=1000
∠A and \angle B∠B are complementary angles. If m\angle A=(x+9)^{\circ}∠A=(x+9)
∘
and m\angle B=(7x-15)^{\circ}∠B=(7x−15)
∘
, then find the measure of \angle B∠B.
Answer:
To find the complement of an angle x, subtract x's measurement from 90 degrees: 90 degrees - x degrees = the measure of x's complementary angle. To find the supplement of an angle y, subtract y's measurement from 180 degrees: 180 degrees - y degrees = the measure of y's supplementary angle.

A scientist looks at a bacterium and a virus in a lab. The bacterium has a diameter of 10 Superscript negative 6 meters. The virus has a diameter of 10 Superscript negative 7 meters. Which statement accurately compares the sizes of the specimens? The diameter of the bacterium is 10 times greater than that of the virus. The diameter of the bacterium is StartFraction 1 Over 100 EndFraction times as great as that of the virus. The diameter of the virus is 10 times greater than that of the bacterium. The diameter of the virus is StartFraction 1 Over 100 EndFraction times as great as that of the bacterium.
Answer: A
Step-by-step explanation:
The diameter of the bacterium is 10 times greater than that of the virus.
The statement that accurately and precisely compares the sizes of the specimens can be seen in the first option.
What is a Superscript?A Superscript is used for the representation of a power at which a number is being raised to. In essence, if we have [tex]a^n[/tex];
a is the base number n is the superscriptFrom the given information;
The diameter of the bacterium = [tex]\mathbf{10^{-6}}[/tex]The diameter of the virus = [tex]\mathbf{10^{-7}}[/tex]We should note that as the exponent increase by -1, it takes an addition [tex] \mathbf{\dfrac{1}{10}=10^{-1}} [/tex]
Therefore, we can say that the diameter of the bacterium is 10 times greater than that of the virus.

One ring in the Stonehenge monument was originally made of 30 stones, each about 6 1/2 feet wide, 3 feet thick, and 13 feet tall. What is the approximate volume of the 17 stones that
remain today?
Answer: V ≈ 4309.5 ft³
Step-by-step explanation: To get the answer to this word problem all we have to do is multiply height * thickness * width.
First, let's turn 6 [tex]\frac{1}{2}[/tex] into a decimal...
1 ÷ 2 = 0.5
6 [tex]\frac{1}{2}[/tex] = 6.5
6.5 * 3 * 13 = 253.5
Now, we have to multiply it by the remaining amount of stones...
253.5 * 17 = 4309.5
V ≈ 4309.5

Which equation represents the statement "One-fourth more than a number is equal to two-thirds?"
Answer: 1/4 + x = 2/3
Step-by-step explanation:
One fourth is written as 1/4, more than is an addition sign, a number means “x”, is equal means = (equal sign), and two thirds is written as 2/3
Answer:

In a right triangle, one leg is 20 cm and the hypotenuse is 30 cm. To the nearest hundredth of a cm, find the length of the missing leg. Formula and diagram required. Include units in your answer.
Answer:
Step-by-step explanation:
Use Pythagoras’ theorem
square of hypotenuse = sum of squares of two other sides
let the missing side be d
30^2 = 20^2 + d^2
600 = 400 + d^2
d^2 = 200
d = square root of 200
d = 14.142 cm
Answer:
22.36
Step-by-step explanation:
For this question we need to utilise Pythagoras theorem. Pythagoras theorem states that a² + b² = c² so the sum of the leg's squared will equal the hypotenuse squared. In this question we are given the hypotenuse so we will have to rearrange the equation to find the value of the leg,
→ a² + b² = c²
⇒ Substitute in the values
→ 20² + b² = 30²
⇒ Simplify
→ 400 + b² = 900
⇒ Minus 400 from both sides to isolate b²
→ b² = 500
⇒ Square root both sides to find the value of the leg
→ b = 22.360679775 cm
The length of the missing leg is 22.36 cm to nearest hundredth considering one leg is 20 cm and the hypotenuse is 30 cm.

Answer the questions attached:
1. I'm not completely sure, but these angles seem to be complementary, meaning they add up to 90°. Since 75° + x = 90°, x = 15°.
2. These lines seem to be parallel. ∠4 ≅ ∠1 because they are vertical angles, ∠5 ≅ ∠1 because they are corresponding angles, and because ∠8 ≅ ∠4 (corresponding angles), ∠8 ≅ ∠1 as well. The final answer is ∠4, ∠5, and ∠8. Hope this helps!

Which is the equation in slope-intercept form for the line that passes through (3, 7)
and is perpendicular to 3x - 5y = 8?
Answer:
[tex]y = - \frac{5}{3} x + 12[/tex]
Step-by-step explanation:
First, rewrite the given equation in the form of y=mx+c.
m is the gradient while c is the y-intercept.
3x-5y=8
5y= 3x -8
[tex]y = \frac{3}{5} x - \frac{8}{5} [/tex]
Thus, the gradient of the given equation is ⅗.
The product of the gradients of perpendicular lines is -1.
(gradient of line)(⅗) = -1
gradient of line= -1 ÷⅗
gradient of line= [tex] - \frac{5}{3} [/tex]
[tex]y = - \frac{5}{3} x + c[/tex]
To find the value of c, substitute a coordinate.
When x=3, y=7,
[tex]7 = - \frac{5}{3} (3) + c[/tex]
7= -5 +c
c= 7+5
c= 12
Hence, the equation of the line is [tex]y = - \frac{5}{3} x + 12[/tex].

Given f(g(x)) = 15x+1 and f(x) = 5x+1. What is g(x)?
Please answer quickly!!
Suppose you are given the two functions f (x) = 2x + 3 and g(x) = –x2 + 5. Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))".

1. What are the coordinates of the vertex of the graph? Is it a maximum or minimum?
Answer:
Hi there!
The correct answer is: (0,1) maximum
Step-by-step explanation:
vertex: the point where the parabola crosses its axis of symmetry.
when the graph is concave down, maximum
when the graph is concave up, minimum
Answer:
Coordinates of the vertex: (0, 1), and it is a maximum.
this corresponds to the second of the listed answer options.
Step-by-step explanation:
Notice that the vertex of the parabola is at the very top of the curve, and corresponds to the maximum value that the coordinate "y" can reach for the parabola (y = 1)
The position of that vertex is exactly at the point where x = 0 and y = 1, so this can be written as:
(0, 1)

The distance between (-1, 4) and (5, 4) is 6 units.
The given Coordinate points are (-1, 4) and (5, 4).
The points are considered as (x1,y1) and (x2,y2).
Here,
x1 = -1 and x2 = 5
y1 = 4 and y2 = 4
Now
[tex]Distance = \sqrt{(x2 - x1)^2 - (y2- y1)^2\\\\= \sqrt{(5 +1)^2 - (4 - 4)^2} }\\\\= \sqrt{36}[/tex]

15x<30
Step-by-step explanation:
Basically 15x<30 is saying that 15x is less that 30. So that means x can be any number as long as when multiplied to 15 it has to be less then 30. So they only number available is 1. So 15(1)<30. Im not sure what the question is but X=1
Answer:
x < 2 or (-∞,2)
Step-by-step explanation:
Treat the inequality sign like an = sign at this point. Don't make it more complicated than it really is. So, to figure it out, you first need to divide each side by 15 so you can get x all by itself:
[tex]\frac{15x}{15} < \frac{30}{15}[/tex]
Now we have:
x < [tex]\frac{30}{15}[/tex]
We know (using simple math) that 30 divided by 15 is 2, which gives us:
x < 2.
In interval notation, this would be (-∞,2). [Remember that the parentheses show that the interval does NOT include the specified numbers, which is what < denotes in our equation.] Hope this helped!
