A banquet room has been set up with 10 tables that each have 8 seats. If 78 people show up for the banquet, how many empty seats will there be?
There would be 2 empty seats.
Explanation:
If we multiply 10x8 we would get 80. If 78 people show up, we would subtract 78 from 80 and our answer would be two.
round off 7284 to 1sf
Answer:
7000
Step-by-step explanation:
This is because when you round to the significant figure, you basically look at any digits at the start of the number, which isn't zero. In this case, it would be in the thousands place 7284. So you round 7284 to the nearest thousands, which, would be 7000

Step-by-step explanation:
a fruitseller bought 50 kg of fruits. he sold 30 kg of fruits for the cost price of 35 kg of fruits and he sold the remaining quantity for the cost price of 16 kg of fruits. calculates his profit and loss percent in the total transactions
Step-by-step explanation:
let the price of fruits be X per kg
cp of 50kg of friuts =50x
he sells 30kg of fruits on its cp of 35 kg
cp of 30kg fruits=30x
sp of 30kg fruits=35x
remaing fruits is 20kg
he sells 20kg of fruits on cp of 16kg
cp of 20kg fruits=20x
sp of 20kg fruits =16x
total cp is =50x
total sp is =(35+16) =51x
sp>cp(it means profit)
profit =sp-cp
=51-50
= 1
profit%=gain/cp × 100
= 1/50×100
=2%

How would the expression (x^2 + 1)(y^2 + 4) be rewritten using Two Squares?
O A. (xy– 2)^2 - (4x+y)^2
B. ( xy- 2)^2 +(2x+y)^2
C. (xy+2)^2 +(x+2y)^2
D. (xy-2)^2+(x+2y)^2
The expression [tex](x^2 + 1)(y^2 + 4)[/tex] can be rewritten using Two Squares as [tex](xy-2)^2+(x+2y)^2[/tex]. The correct option is D.
What is Two Squares?The Two Squares identity is a special case of the identity: [tex](a^2 + b^2) = (a + b)^2 - 2ab[/tex].
This identity can be used to factorize certain expressions involving squares of variables.
By using the Two Squares identity, we can rewrite expressions in the form of a sum of two squares as a difference of squares, or vice versa. This can be useful in simplifying and solving equations in algebra.
We can use the Two Squares identity, which states that:
[tex](a^2 + b^2)(c^2 + d^2) = (ac - bd)^2 + (ad + bc)^2[/tex]
Comparing with the given expression, we can see that a = x, b = 1, c = y, and d = 2. Substituting these values into the Two Squares identity, we get:
[tex](x^2 + 1)(y^2 + 4) = (xy - 2)^2 + (x + 2y)^2[/tex]
Therefore, the answer is (D) [tex](xy-2)^2 + (x+2y)^2.[/tex]

Step-by-step explanation:
The correct order of steps for copying the angle ABC is BFCEDA.
What is copying the angle?The process of copying an angle through construction involves ensuring that the distance between the two rays forming the angle is the same.
The steps which are required for copying the angle are:
Draw a ray, of the copy of the angle as a ray with an endpoint, D.In the given angle ∠ABC, with the compass placed at point B, construct an arc that intersect the two sides of the given line (BA at point E, and BC at point F) by opening the compass to a radius, r.Place the compass at the point D on the line l and with the radius r from above, draw an arc (D, r) that intersects the line l at the point G.Place the compass at point E on line AB, and construct an arc passing through point F, therefore having radial length EF.Place the compass at point G and construct an arc with radial length EF that intersects the arc (D, r) at point H and draw a ray from the point D passing through point H to complete the construction.Hence, the correct order of steps for copying the angle ABC is BFCEDA.

Two mechanics worked on a car. The first mechanic worked for 10 hours, the second mechanic worked for 5. Together they charged a total of 950$ What was the rate charged per hour by each mechanic if the sum of the two rates was 125$ per hour?
Answer:
Step-by-step explanation:
Let x = the hourly rate of the first mechanic and
y = the hourly rate of the second mechanic.
As far as the equation goes for the total amount charged:
10x + 5y = 950
As far as the equation goes for the sum of the 2 mechanics' rates:
x + y = 125
Solve the first equation for either x or y. I solved for y:
y = 125 - x
Now plug that into the first equation for y to get:
10x + 5(125 - x) = 950 and
10x + 625 - 5x = 950 and
5x = 325 so
x = 65
The first mechanic charges $65 per hour and the second mechanic charges
y = 125 - 65 so
the second mechanic charges $60 per hour.

x=8/4
x=2
Answer: x = 2
Concept:
There are many properties for parallelograms, however, here, we need to focus on one property about diagonals.
Diagonals of a parallelogram bisect each other.
Solve:
Given information
One side of the diagonal = 6x
The other side of diagonal = 2x + 8
Given expression deducted from the property of parallelogram
One side = Other side
Substitute values into the expression
6x = 2x + 8
Subtract 2x on both sides
6x - 2x = 2x + 8 - 2x
4x = 8
Divide 4 on both sides
4x / 4 = 8 / 4

Next is + 6.
19 + 6 = 25
Now + 7.

Find the 7th term of the geometric sequence shown below
10x^3, 40x^8, 160x^13,…
Answer:
[tex]a_7=40960x^{33}[/tex]
Step-by-step explanation:
Geometric sequence has explicit form:
[tex]a_n=a \cdot r^{n-1}[/tex] where [tex]a[/tex] is first term and [tex]r[/tex] is the common ratio.
First term here is [tex]a=10x^3[/tex] and [tex]r[/tex] could be found by doing second term divided by first term, [tex]\frac{40x^8}{10x^3}=4x^5[/tex].
Therefore the [tex]n[/tex]th term is given by
[tex]a_n=10x^3 \cdot (4x^5)^{n-1}[/tex].
So the [tex]7[/tex]th term is given by
[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex].
Let's simplify:
[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex]
[tex]a_7=10x^3 \cdot (4x^5)^{6}[/tex]
[tex]a_7=10x^3 \cdot (4^6(x^5)^6)[/tex]
[tex]a_7=10x^3 \cdot (4096x^30)[/tex]
[tex]a_7=40960x^{33}[/tex]
