Solve the equation 25=7+r

Answer: 7095.4

Because the digits following 7095 are .38, you would need to round the 3 to a 4 to get the nearest tenth

Answer: 97.6 in3

Step-by-step explanation:

Hi, to answer this question we have to calculate the volume of the cylinder and subtract the volume of the cone:

Volume of a cylinder: π (diameter /2) ^2 (height)

Vcy = π (4 /2) ^2 (8) = π (2) ^2 (8) =100.5 in3

Volume of a cone = 1/3 π (diameter /2) ^2 (height)

V Co = 1/3 π (4/2) ^2 (0.7) = 1/3 π (2) ^2 (0.7) = 2.9 in3

Finally:

Volume of the cylinder - volume of the cone = 100.5-2.9 = 97.6 in3

Answer:

4 x minus 5 y = negative 5 and 3 x + 10 y = negative 20

Step-by-step explanation:

The equations

4 x - 5 y = 5 (red)

3 x + 10 y = 20 (blue)

4 x - 5 y = -5 (green)

3 x + 10 y = -20 (purple)

are shown in the picture attached. As we can see there, the point (–2.7, –1.2) is on the intersection of the purple and green lines. Therefore is the solution of the system:

4 x - 5 y = -5

3 x + 10 y = -20

Step-by-step explanation:

Answer:

b) 42°

Step-by-step explanation:

When two triangles share the same base (in this case,  side QR), one angle is half of the other one. In this case:

1/2*∠QPR = ∠QSR

From the picture,

∠QSR = 21°

Replacing into the equation and solving for ∠QPR:

∠QPR = 2*21° = 42°

Answer:

Width of field  = 50 yards

Length of Yards =  106 yards

Step-by-step explanation:

Let the width of field be x yards

given that "The length of a new rectangular playing field is 6 yards longer than double the width"

Length of Yards= 2*width of field + 6 = 2x+6 yards

perimeter of the rectangular playing field  = 312 yards

We know that perimeter of rectangle is given by 2(length + width ).

Since field is rectangular then

2(length + width ) = 312

2(x+2x+6) = 312

=> 3x+6 = 312/2 = 156

=> 3x = 156 - 6 = 150

=> x = 150/3 = 50

Thus,

Width of field is x = 50 yards

Length of Yards=  2x+6 yards = 2*50+6  yards = 106 yards

True

Step-by-step explanation:

Answer:

Hai

Yes, its true.

because in 21, there are 4 times of 5 and we have left 1 number..

you can multiply -4 with 5 and add the number of the denominator (1)

i wanna give one more example because couldnt explained well.

3 2/3 can be written as 11/3.

you can try it too!

Answer:

Step-by-step explanation:

2x + 5y = 3

y = x + 2

2x + 5(x + 2) = 3

2x + 5x + 10 = 3

7x + 10 = 3

7x = -7

x = -1

y = -1 + 2

y = 1

(-1, 1)

Answer:

The pattern in decimal expressions is that the decimal numbers are repeated immediately after the decimal point.

The pattern in the equivalent fraction is that 9 is on all fractions

Step-by-step explanation:

All the cases (0.111..., −0.555...,  −1.222... and 5.888...) are solving by the following procedure (only one example is shown):

x = 0.111111...

10x = 1.11111...

10x - x = 1.11111... - 0.111111...

9x = 1

x = 1/9

which is equivalent to express the decimal part as the tenth divided by 9. Then:

−0.555...= −5/9,

−1.222...(repeating)= −1 2/9,

5.888...(repeating)= 5 8/9

Answer:127.5∘

Step-by-step explanation:

The angle measure between any two consecutive numbers on a clock is 36012=30∘.

Call the "12" point on the clock the zero-degree point.

At 4:45, the minute hand is at the "9" - that is, at the 30×9=270∘ mark. The hour hand is three-fourths of the way from the "4" to the "5; that is,

30×434=142.5∘ mark.

Therefore, the angle between the hands is

270−142.5=127.5∘, the desired measure.

Answer:

C

Step-by-step explanation:

A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix.

Focus  is the name of the point that you use to define a parabola

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped

A parabola is a symmetrical U-shaped curve that can be defined as the set of all points that are equidistant to a fixed point (called the focus) and a fixed line (called the directrix).

The vertex is the point where the parabola changes direction and is located halfway between the focus and the directrix.

The center is a term used to refer to the midpoint of the line segment connecting the two foci of an ellipse or hyperbola, and is not relevant to a parabola.

Hence,  Focus  is the name of the point that you use to define a parabola

Answer:

114.89 V

Step-by-step explanation:

Watts are a measure of power, and there is an equation that relates power, voltage, and resistance. It goes like this:

P=(V^2)/R

Now to find the voltage you want to solve for V

PR = V^2

V = [tex]\sqrt{PR}[/tex]

Now substitute your numbers into the equation and you get your answer

V = [tex]\sqrt{(60)(220)}[/tex]

V = [tex]\sqrt{13200}[/tex]

V = 114.89 V
