Answer:
411
Step-by-step explanation:
Because it has a 4 , 1 , and a 1
meaning the first number can't be 1 so it is automatically a 4.
and then the only 2 numbers left is 2 one's so you have to put them in their also automatically and 4 is asking 1 to round up can it.
411 can't round up,it would round down because 1 is 4 and below so it can't go up and goes down.
so 4 1 1 can't go up the number would have to be 450 to go to 500 but because it is 411 it goes down to 400 because it is rounded to 400.
Hope this helps have a awesome day:)
Given u = (2, -8) and v = (8, -2), what is u times v?
Answer:
[tex]u\cdot v=32[/tex]
Step-by-step explanation:
Assuming [tex]u[/tex] and [tex]v[/tex] are vectors, their dot product is [tex]u\cdot v[/tex] where [tex]u_1v_1 + u_2v_2[/tex]:
[tex]u\cdot v=u_1v_1+u_2v_2=(2)(8)+(-8)(-2)=16+16=32[/tex]
Therefore, [tex]u\cdot v=32[/tex]

Answer:
113.04
Step-by-step explanation:
The area of the square is 144 which means the length of each side of the square is 12. When the length on one side is 12 the radius of the circle will be half of the whole length. In this case, it means the radius is going to be 6. When we find the radius, we can use the formula r^2pie to find the area for the circle.
6 * 6 * 3.14
= 113.04
Answer:
Area = 113.04 in²
Step-by-step explanation:
Given:
Area of the square = 144 in²Area of a square
[tex]\sf A=s^2\quad \textsf{(where s is the side length)}[/tex]
Substitute the given area of the square into the formula and solve for s:
[tex]\begin{aligned}\sf A & = \sf s^2\\\implies \sf 144 & = \sf s^2\\\sf \sqrt{144} & = \sf \sqrt{s^2}\\\sf 12 & = \sf s\\\implies \sf s & = \sf 12\:\:inches\end{aligned}[/tex]
From inspection of the given diagram, the side length of the square is equal to the diameter of the circle. Therefore, the diameter is 12 inches.
Radius of a circle
[tex]\sf r = \dfrac{1}{2}\:d\quad \textsf{(where d is the diameter)}[/tex]
Substitute the found diameter into the formula and solve for r:
[tex]\begin{aligned}\sf r & = \sf \dfrac{1}{2}\:d\\\implies \sf r & = \sf \dfrac{1}{2}(12)\\\sf r & = \sf 6\:\:inches\end{aligned}[/tex]
Area of a circle
[tex]\sf A= \pi r^2 \quad \textsf{(where r is the radius)}[/tex]
Substitute the found radius into the formula and solve for A:
[tex]\begin{aligned}\sf A & = \sf \pi r^2\\\implies \sf A & = \sf 3.14 \cdot 6^2\\& = \sf 3.14 \cdot 36\\& = \sf 113.04\:\: in^2\end{aligned}[/tex]
Therefore, the approximate area of the paper circle is 113.04 in².

Which is the best estimate for the volume of a coffee mug?
Answer:
Step-by-step explanation:
The best estimate for the volume of a coffee mug would be the volume of a cylinder. The volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
The volume can be thought of as the area of a circle, being scaled by the height. The area of the circular base of the mug, multiplied by the height of the mug.

Find the area of the following shapes.
Area = __ mm^2
Answer:
Formulae used:
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
Area of blue shape:
Area of rectangle + area of triangle
= (9 × 15) + (1/2 × (15 - 9) × 15)
= 135 + (1/2 × 6 × 15)
= 135 + 45
= 180 mm²
Area of yellow shape:
area of rectangle AHPB + area of rectangle GFQP + area of rectangle EDCQ
= (4 × 12) + (6 × (12 - 9)) + (4 × 12)
= 48 + (6 × 3) + 48
= 48 + 18 + 48
= 114 m²

Enter the answer, rounded to the nearest hundredth.
Answer:
The answer is 4.94, rounded.
Step-by-step explanation:
The pythagorean theorem is : a^2+b^2=c^2
Inserting our numbers:
3.4^2+b^2=6^2
We can find 'B' by finding the other two numbers and subtracting 'A', from 'C'.
3.4*3.4= 11.56
6*6= 36
36-11.56= 24.44
Then, find the root of the difference
√24.44

What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
A sum of money is divided between Laura and Joan in the ratio 2:3.
Laura’s share is $8.
Let J be the amount of Joan's share and L be the amount of Laura's share.
Then the amount of Joan's share will be
L / J = 2 / 3
8 / J = 2 / 3
By the cross multiplication, then the equation will be
2J = 8 x 3
2J = 24
J = 24 / 2
J = $12
The amount of the Joan's share will be $12.

Solve completely \large x^4-4=x^3+2x
Move everything to one side and factorize by grouping.
x⁴ - 4 = x³ + 2x
x⁴ - x³ - 2x - 4 = 0
(x⁴ - 4) - (x³ + 2x) = 0
(x² - 2) (x² + 2) - x (x² + 2) = 0
(x² - x - 2) (x² + 2) = 0
(x - 2) (x + 1) (x² + 2) = 0
Then
x - 2 = 0 or x + 1 = 0 or x² + 2 = 0
x = 2 or x = -1 or x² = -2
If x is real, then the third case has no solution. Then x = 2 or x = -1. Otherwise, we can solve over the complexes and include x = ± √2 i where i = √(-1).

Answer:
Its solving equations with variable on both sides
Step-by-step explanation:
Example: 8a = 3a+25
You have to make a variable on the both side
So.....
8a-3a = 3a+25-3a
And then solve it. So the last thing you will have is
5a = 25
If you want to the simplest form...divide 25 with 5
a = 25/5
a = 5

Abby earns a monthly salary of $3462 plus 2% commission. Last month, she sold
$5,250 worth of products. What was her gross pay?
Find 2% of what she sold by multiplying the amount she sold by 2%:

Now add that to her monthly salary:
3462 + 105 = $3,567
What are the pros and cons of using disposable plastic and paper products for dine-in fast food restaurants over reusable plates, cups, and silverware? atleast 2 pros and 2 cons
Answer:
Disposable items decompose after some time thus making them eco-freindly(safe for the environment) they also don't make a giant mess that takes thousands of years to decompose and even if they do it doesn't take that long for them to decompose on the other hand they are more expensive to mass produce than reusable items and they also are more expensive to buy than non Disposable but reusable items.Non disposable but reusable Items when thrown away can take decades or even in some cases tens of thousands of years to decompose and can pose a threat to the environment they can be eaten by fish and other animals causing them in some cases to die they can cause a giant mess on the other hand they are cheap,and quick to make and you don't have to pay as much for dishes.=
Write an exponential function y = abx whose
graph passes through the points (1,6), (2, 18)
Answer:
[tex]2(3) {}^{x} [/tex]
Step-by-step explanation:
[tex]y = ab {}^{x} [/tex]
We know that when x=1, y=6
[tex]6 = a {b}^{1} [/tex]
x=2, y=18
[tex]18 = a {b}^{2} [/tex]
Notice that if we divide
[tex] \frac{ {ab}^{2} }{ab} = b[/tex]
So if we divide 18 and 6, that will give us our common ratio.
[tex] \frac{18}{6} = 3[/tex]
So our common ratio is 3.
So know we have
[tex]a(3) {}^{x} [/tex]
Plug in one of the points to find a.
[tex]6 = a(3)[/tex]
[tex]a = 2[/tex]
So the equation. we have
[tex]2 \times ({3}^{x} )[/tex]

which is like a radical to ^3 to the square root of 54 after simplifying
Answer:
The radical that is equal to ∛54 is 3∛2.
Step-by-step explanation:
Given
∛54
We need to find the radical that is similar to ∛54, we need to break down the radicand 54, into smaller numbers, therefore, take the LCM of the number,
54 = 2 x 3 x 3 x 3
As we are taking the cube root, therefore, we need numbers that are repeating thrice.
Thus, the radical can be written as,
[tex]\sqrt[3]{54} =\sqrt[3]{2x 3x 3x 3} \\\\\sqrt[3]{54} =3\sqrt[3]{2}[/tex]
Hence, the radical that is equal to ∛54 is 3∛2
Answer:
[tex]3\sqrt[3]{2}[/tex]
Step-by-step explanation:
Original expression:
[tex]\implies \sqrt[3]{54}[/tex]
Factorize 54 using prime factorization:
[tex]\implies \sqrt[3]{2 \cdot 3^3}[/tex]
Apply radical rule: [tex]\sqrt[n]{ab} =\sqrt[n]{a} \cdot \sqrt[n]{b}[/tex]
[tex]\implies \sqrt[3]{2} \cdot \sqrt[3]{3^3}[/tex]
Apply radical rule: [tex]\sqrt[n]{a^n} =a[/tex]
[tex]\implies \sqrt[3]{2} \cdot 3[/tex]
[tex]\implies 3\sqrt[3]{2}[/tex]

Ava, Zoe and Logan went to the market to buy some presents for a friend's birthday. The three of them
together spent $720. If Logan spent twice as much Zoe did and Zoe spent $40 less than Ava did, how
much did each of them spend?
a + z + l = 720
l = 2z = 2a - 80
4z + 40 = 720
4z = 680
z = 170
l = 340
a = 210
