Answer:
They had 1,352 marbles all together, rounded to the nearest hundred, 1,400.
Step-by-step explanation:
All we have to do is add the number of marbles they collected.
510 + 842 = 1,352
1,352 rounded to the nearest hundred is 1,400.

Step-by-step explanation:
r=3/2=(4.5)/3=3/2
it is geometric, so we will use this equation:
a(n)=a1*(r)^(n-1)
and we have a(1)=2 , r=3/2
So explicit formula:
a(n)=2*(3/2)^(n-1)

Answer:
x = 165°
Step-by-step explanation:
x° = 360 - (the measure of one interior angle of the octagon + the measure of one interior angle of the equilateral ∆)
Each interior angle of a regular octagon = 135° ([tex] \frac{(n - 2)180}{n} = 135°)
An equilateral ∆ has equal angles, each measuring 60°.
Therefore:
x° = 360° - (135° + 60°)
x = 360 - 195
x = 165°
Answer:
165°

choose a number between 67 and 113 as a multiple of 3, 5 and 10
Answer: 90
Step-by-step explanation:
90 / 3 = 30
90 / 5 = 14
90 / 10 = 9
Therefore, 90 is between 67 and 113. It is also a multiple of 3, 5, and 10.
Identify the domain of the function shown in the graph.
Answer:
D. [tex]x\geq 0[/tex]
Step-by-step explanation:
In order to answer this question we need to know the definition of the domain. The domain of a function is the complete set of possible values of the independent variable ("x"). In our case we can look at the function and cross out option "A" because the function has no point with a negative "x" value. Option "B" can be also crossed out because it states that "x" values can not go above 3 but by looking at the function we can see multiple point with "x" values larger then 3. Option "C" can also be crossed out because their is not point on the function that would have a negative "x" value which contradicts the statement about all numbers. And finally we are left with "D" and we know it is the right answer since the function has a point with "x" value being equal to 0 and the all other points have the "x" value greater then 0, which is exactly what option "D" states.

Find the exact value of sec 330° in simplest form with a rational denominator.
Answer:
2√3/3
Step-by-step explanation:
Sec(330°)
=1/cos(330°)
=1/√3/2 (since Cos (330°)=√3/2
=1×2/√3
=2/√3×√3/√3
=2√3/3
Answer:
[tex]\implies \sec 330^o = \dfrac{2}{\sqrt3}=\dfrac{2\sqrt{3}}{3}[/tex]
Step-by-step explanation:
Given :-
[tex]\sec 330^o [/tex]And we need to find out its value . Firstly we know that 330° lies in 4th quadrant . And In fourth quadrant , cosine and secant are positive . Therefore , the result will be positive. Now we know that ,
[tex]\implies \sec (360^o-\theta)= \sec\theta [/tex]
Using this ,
[tex]\implies \sec (330^o) \\\\\rm\implies sec(360^o-30^o) \\\\\rm\implies \sec 30^o [/tex]
And the value of sec 30° is ,
[tex]\implies \sec 30^o = \dfrac{2}{\sqrt3}[/tex]
And by question we need to write it with a rational denominator .So on rationalising the denominator , we have ,
[tex]\implies \sec 30^o = \dfrac{2}{\sqrt3}=\boxed{\red{\dfrac{2\sqrt3}{3}}}[/tex]
Hence the required answer is 2√3/3.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
-5x + y = 1
9x - 2y = 4
Step 2: Rewrite Systems
-5x + y = 1
Add 5x on both sides: y = 5x + 1Step 3: Redefine Systems
y = 5x + 1
9x - 2y = 4
Step 4: Solve for x
Substitution
Substitute in y: 9x - 2(5x + 1) = 4Distribute -2: 9x - 10x - 2 = 4Combine like terms: -x - 2 = 4Isolate x term: -x = 6Isolate x: x = -6Step 5: Solve for y
Define equation: -5x + y = 1Substitute in x: -5(-6) + y = 1Multiply: 30 + y = 1Isolate y: y = -29What is the value of 4x+1

Alton is making a sandbox for his kids in the backyard. He has 400 feet of board for the sides of the sandbox. A. Define the function A(w) to represent the area of the sandbox as a function of the width. Explain your reasoning. B. Determine the maximum area of the sandbox as well as the length and width that will result in the maximum area. Explain your reasoning.
Answer:
The answer is below
Step-by-step explanation:
a) Let the width be represented as w and the length be represented as l.
The perimeter of the sand box = 2(l + w)
Since there is 400 feet of material for the sides of the sandbox, hence:
400 = 2(l + w)
200 = l + w
l = 200 - w
The area (A) is:
A = length * width
A = (200 - w) * w
A(w) = 200w - w²
b) The maximum area is at A'(w) = 0. Hence:
A'(w) = 200 - 2w
200 - 2w = 0
2w = 200
w = 100 feet.
l = 200 - w = 200 - 100
l = 100 feet.
Area = length * width = 100 * 100 = 10000 feet²
The maximum area of the sandbox is 10000 feet², with a length of 100 feet and width of 100 feet.

Answer:a=4
Step-by-step explanation:
Expand the brackets. Collect like terms. Get the same values on each side so it’s easier to isolate a. Divide 9 from 9a so that u get a by itself and this gives u the answer if 36/9 or 4.
Answer:
a = 4
Step-by-step explanation:
first distrubute the 3 and then 2 in the equations to whatever is inside the parantheses:
3 ( 1-9a) + 22a = 2(2a-9) -15
3 - 27a + 22a = 4a - 18 - 15
then combine the terms:
3 - 5a = 4a -33
then isolate the variables and constants to one side, for example move the 5a to the right side of the equation and move the 33 to the left side of the equaiton and then simplfy
36 = 9a
divide both sides by 9
a = 4

Idahtonye has ₦50.00. He buys six mangoes and gets ₦2 change. Find the average cost of one mango. step by step explanation.
Answer:
The average cost of one mango = c = ₦8
Step-by-step explanation:
Let 'c' be the average cost of one mango
The original amount Idahtonye has = ₦50.00
The amount of mangoes Idahtonye buys = 6 mangoes
As he gets back the change of ₦2 after paying ₦50.00 to buy 5 mangoes.
Thus the equation becomes
50 - 2 = 6c
48 = 6c
dividing both sides by 6
48/6 = 6c/6
c = 8 ₦
Therefore, the average cost of one mango = c = ₦8
Light travels about 186,000 mi /s. The function d(t) = 186,000t gives the distance d(t), in miles, that light travels in t seconds. How far does light travel in 30 s
D(t) = 186,000 t
D(30) = 186,000 • 30
D(30) = 5,800,000 miles
Hope this helps!
The light will travel 5,580,000 miles in 30 seconds.
To understand the calculations, check below.
Distance :The distance traveled by light is represented by function.

Answer:
A) y ≥ 350x + 17,000
Step-by-step explanation:
If 17,000 is the original, you won't multiply or divide it by x. But since it goes up by at least 350 each year you will multiply by x.
So to set it up, you will have 350x + 17,000, and since it's at least, you will have a great than or equal to sign (≥)
y ≥ 350x + 17,000
