PLEASE HELP ASAP

In the diagram, y= x-15 and z=125. What is the value of x?

Answer:

It will cost 63.25

Step-by-step explanation:

We can use a ratio to solve

46 dollars       x dollars

--------------- = ---------------

8 people         11 people

Using cross products

46 * 11 = 8x

506 = 8x

Divide each side by 8

506/8 =8x/8

63.25 =x

It will cost 63.25

Answer:

$63.25

Step-by-step explanation:

46/8 = $5.75 each

11 x 5.75 = $63.25

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.

hope this helps!

Answer:

the answer is d just check by ordinary way

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.

I hope this helped :))

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

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:

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.

Answer:

y=-7 and x=-3

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)

and -x+y=-4→(2)

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

⇒x=-3→(4)

Now, Putting x=-3 in equation (3), we get

y=2x-1

⇒y=2(-3)-1

⇒y=-6-1

⇒y=-7

∴y=-7andx=-3

lower than Amanda:  816 students

Step-by-step explanation:

An equivalent way in which to state this problem is:  Find the area under the standard normal curve to the left (below) 940.

Most modern calculators have built in distribution functions.

In this case I entered the single command   normalcdf(-1000,940, 850, 100)

and obtained 0.816.

In this particular situation, this means that 0.816(1000 students) scored lower than Amanda:  816 students.

Answer:

Answer:

120

Step-by-step explanation:

if you do 4200 x 35 it well be 147000 but if you divide 4200 ÷ 35 it will be 120 and in the question said Each so each mean =× or ÷ in this case it's divide

Answer: 3780

Step-by-step explanatio

35 multiply it with 12 cause there are 12 months in a year then subtractEd it with 4200 and 420 cause that is what I got. Then got 3780!

35 x 12 = 420 then 4200 - 420= 3780

The options aren't given, however, the range of amount spent could be calculated

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.

Answer:

16 times

Step-by-step explanation:

difference in area = area of bigger circle / area of smaller circle

Area of a circle = πr²

r = radius

imagine the radius of the smaller circle = 1

Area of circle in terms of π= π

radius of the bigger circle = 4 x 1 = 4

Area of bigger circle in terms of π  = π4² = 16 π

16 π /  π = 16  times

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.
