Answer:
The surface area of the red square is 180, and the surface area of the blue square is 328. So the full answer is 508.
Step-by-step explanation:
A = 2( width times length +height times length +height times width ) = 2(6 times 3 + 8 times 3 + 8 times 6)=180
A = 2(width times length + height times length + height times width) = 2(2 times 12 + 10 times 12 + 10 times 2) = 328
And 328 + 180 = 508.
The arithmetic sequence as is defined by the formula:
ai = -4910
ai = Ai-1 +8
Find the sum of the first 575 terms in the sequence.
Answer:
An arithmetic sequence is a sequence such that the difference between two consecutive terms is a constant, and we can call it d.
Then the general recursive relation is:
Aₙ = Aₙ₋₁ + d.
And the sum of the first N terms of this sequence is given by:
S(N) = (N/2)*(2*A₁ + (N - 1)*d)
Where A₁ is the first term of the sequence.
In this case, we have:
A₁ = -4910
Aₙ = Aₙ₋₁ + 8
Then we have: d = 8
(it actually says:
ai = -4910
ai = Ai-1 +8
But that has no actual meaning, so I assumed that the first one was actually the first term of the sequence)
The sum of the first 575 terms of this sequence is given by:
S(575) = (575/2)*(2*(-4910) + (575 - 1)*8) = -1,503,050

Five angles of a hexagon measures 119, 129,104,139 and 95 degrees. What is the measure of the sixth angle?
Answer:
x = 134
Step-by-step explanation:
Given that,
Five angles of a hexagon measures 119, 129,104,139 and 95 degrees.
We know that,
The sum of interior angles of a hexagon must equal 720 degrees.
So,
119+129+104+139 +95+x = 720
Where
x is the sixth angle
So,
586+x=720
x = 720-586
x = 134
So, the sixth angle is equal to 134.

Answer:
m∠XCY = 60°
Step-by-step explanation:
From the figure attached,
Circle has been given with the inscribed angles ∠XWY and ∠XCY formed by the same arc XY.
By the property of the inscribed angles,
"Measure of the inscribed angle formed by the same arc are equal"
m∠XWY ≅ m∠XCY
60x = 61x - 1
61x - 60x = 1
x = 1
Therefore, m∠XCY = 61x - 1
= 61(1) - 1
= 60°

Answer:
Kindly check explanation
Step-by-step explanation:
Paula purchase 3 dvd and 7 cds and spent between 90 and 100. Each dvd costs the same amount the price of cd is 10 select all amounts that could be the price of the dvd
Given that :
DVD costs the same amount
Number of DVD's = 3
Cost of cds = 10
Number of cds = 7
Total cost of cd's = 10 * 7 = 70
Let the price of DVD = x
Total amount spent = 90 - 100
Lowest price of DVD :
(amount spent - price of cd) / number of dvd
(90 - 70) / 3 = 20 /3 = 6.667
Highest price :
(100 - 70) / 3 = 30 / 3 = 10
Hence the pice of each DVD will range between /
6.6666 and 10.
Hence, prices listed within the range above are possible.

=============================================================
Explanation:
The circumference is a special term to mean the perimeter of a circle, or the distance around the circle. Think of a very long rope you can wrap around the circle. Unwinding that rope to make it lay straight can then lead to help measure out the perimeter of the circle when using a straight measuring device (eg: ruler). You can also think of flexible cloth ruler tape that is used to make clothing, and to measure things like height, when thinking about measuring the perimeter of a figure with curves to it.
In this case, the perimeter of the circle is 628 feet. The formula to find the circumference (C) given a radius (r) is shown below
C = 2*pi*r
where pi = 3.14 approximately. We can use a bit of algebra to find the radius r when we are given the circumference C = 628
So,
C = 2*pi*r
628 = 2*3.14*r
628 = 6.28*r
6.28r = 628
r = 628/6.28
r = 100
The radius is 100 feet. Keep in mind that this is an approximate value considering that pi = 3.14 is approximate.
Now we're told that the boat is moving 4 ft per second along the radius. We'll use the distance = rate*time formula to find out how long it will take us to go from the edge fo the center.
distance = rate*time
100 ft = (4 ft per sec)*(x seconds)
100 = 4x
4x = 100
x = 100/4
x = 25
It takes about 25 seconds for the boat to go from the edge to the center of the pond.
Again, this is an approximation due to pi = 3.14 being an approximation.
Answer:
25 seconds
Step-by-step explanation:
the first step is to find the radius of the pond, as that is the distance from the outside of the circle to the center, the same path the boat is taking. the formula for the circumference of a circle is 2pi(r)= circumference, where r represents the radius. to solve for the radius instead of the circumference, we can format the equation as r= circumference/2pi, because to isolate the radius on the left side of the equation you must divide by 2pi on both sides. we know the circumference is equal to 628, so the equation filled out is r= 628/2pi. firstly, 2*pi is 6.28, using 3.14 as pi. 628/6.28 is 100, so the radius is 100 feet.
next, we know the boat is travelling 4 feet per second. since the path it is travelling is 100 feet long, we must divide 100 by 4. 100 ft divided by 4 ft per second leaves us with 25, so it will take the boat 25 seconds to reach the center of the pond.

Select all equations whose graphs have a vertex with x-coordinate 2
A. y=(x-2)(x-4)
B. y=(x-2)(x+2)
C. y=(x-1)(x-3)
D. y=x(x+4)
E. y=x(x-4)
Answer:
C
Step-by-step explanation:
because you have to foil then do -b/2a
By finding the x-coordinate of each vertex, we will see that the correct options are C and E.
How to identify the x-value of the vertex?
For a quadratic equation of the form:
y = (x - a)*(x - b)
Where a and b are the roots, such that a < b, the x-value of the vertex is given by:
a + (b - a)/2
With that, we can check the x-value of the vertex of each option.
A) y=(x-2)(x-4)
The x-value of the vertex is:
2 + (4 - 2)/2 = 3
B) y=(x-2)(x+2)
The x-value of the vertex is:
-2+ (2 - (-2))/2 = 0
C) y=(x-1)(x-3)
The x-value of the vertex is:
1 + (3 - 1)/2 = 2
D) y = x(x+4) = (x - 0)*(x + 4)
The x-value of the vertex is:
-4 + (0 - (-4))/2 = -2
E) y=x(x-4) = (x - 0)*(x - 4)
The x-value of the vertex is:
4 + (0 - (4))/2 = 2
So the two options that have a vertex with x-coordinate 2 are options C and E.

Step-by-step explanation:
Answer:
Y =-7 and X -3
Solution:
4x-2y=2
2(2x-y)=2⋅1
2x-y=1
and y+4=x
∴y-x=-4
Suppose,
2x-y=1→(1)

Taking equation (1), we have
2x-y=1
⇒y=2x-1→(3)
Putting y=2x-1 in equation (2), we get
-x+y=-4
-x+(2x-1)=-4
⇒-x+2x-1=-4
⇒x-1=-4
⇒x=-4+1
⇒x=-3

Answer:
The final answer is 55/8 or the first option.
Step-by-step explanation:
Example equation: a·b/c. To solve this you need to first do a·c and add b to it. For example, you have 5 pizzas and one extra pizza with 2 slices. Each pizza has 8 slices. In all, you have the amount of slices in the 5 whole pizzas + the amount of slices in the partially eaten pizza. Hence, you have (5 whole pizzas · 8 slices in each pizza)+2 slices. This gives you 40+2, or 42 slices in all. The final answer is 42/8.
The same concept applies here. You have 6 whole pizzas with 8 slices in each pizza, + 1 partially eaten pizza that has 7 slices. The expression is (6 whole pizzas · 8 slices in each pizza)+7 slices. This gives you 48+7 or 55 slices in all. The final answer is 55/8 or the first option.

Mancini's Pizzeria sells four types of pizza crust. Last week, the owner tracked the number sold of each type, and this is what he found.
Type of Crust Number Sold
Thin crust 364
Thick crust 240
Stuffed crust 176

Based on this information, of the next 3000 pizzas he sells, how many should he expect to be thick crust? Round your answer to the nearest whole number. Do not round any intermediate calculations.
Answer:
692 thick crust pizzas
Step-by-step explanation:
With the data given in the exercise, we must first find the total number of pizzas, then we must find the proportion between the thick crust pizzas and the total number of pizzas, finally we must propose a rule of three to find the new proportion of crust pizzas thick on a total of 3000 pizzas.
Type of Crust Number Sold
Thin crust 364
Thick crust 240
Stuffed crust 176
Pan style 260
total pizzas : 1040
Now we must calculate for 3000 pizzas how much would be the total of thick crust pizzas.For that we must use the relationship found, that is, in 1040 pizzas there are 240 thick crust pizzas
1040→240
3000→x
x= [tex]\frac{3000x240}{1040}[/tex] = 692
Now we have a new proportion that out of 3000 pizzas there are a total of 692 thick crust pizzas
