Answer:

13/2

Step-by-step explanation:

5 2/3 gets changed to 13/3 and you multiply that by 3/2 because of keep change flip. After multiplying you get 39/6 and you simplify to get 13/2.

No

0.5 ≠ 0.8

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Answer:

No, it is not.

Step-by-step explanation:

The reason is that if you simplified  4/8, you will get 1/2. When you simplified 8/10, you will get 4/5. 1/2 and 4/5 aren't the same number or equivalent to each other so the answer will be no.

Answer:

1.5%.

Step-by-step explanation:

x per cent is written as 0.01x as a decimal fraction.

638.30 = 550(1 + 0.01x)^10

(1 + 0.01x)^10 = 638.30/550

Taking logarithms:

10 ln (1 + 0.01x) = ln ( 638.30/550)

ln (1 + 0.01x) =  ln ( 638.30/550)/ 10

ln(1 + 0.01x) = 0.014889

Converting the logs:-

1 + 0.01x = e^0.014889 = 1.015

0.01x = 1 - 1.015

0.01x = 0.015

x = 0.015/ 0.01

= 1.5.

Answer:

Question 1: x = 3, y = 2

Question 2: x = 0.5

Step-by-step explanation:

Question 1 explanation: In a parallelogram, both the horizontal and the vertical sides are equal, this means that [tex]2y + 3 = y + 5[/tex] ⇒ [tex]y = 2[/tex]. Since you've already figured out the value of y, you can input the value to side QR to help find x. [tex]4x-3=4*2+1[/tex] ⇒ [tex]4x-3=9[/tex] ⇒ [tex]4x=12[/tex] ⇒ [tex]x=3[/tex]. So x equals 3 and y equals 2.

Question 2 explanation: Since side AE is equivalent to side EC, that means quadrilateral ABCD is a parallelogram. In a parallelogram, the diagonal lengths from the corners of the shape to the center are equal, which means [tex]10x = 2x + 4[/tex] ⇒ [tex]8x=4[/tex] ⇒ [tex]x = 0.5[/tex].

Answer:

ex2 = e4x+5 --> 5, -1

ln(x+5)=ln(x-1)+ln(x+1) --> 3

log(4)(5x^(2)+2)=log(4)(x+8) --> -1, 6/5

log(x-1)+log5x=2 --> 5

The diameter od the ciruclar ground given the circumference is  126 m.

The circumference of a circle is the distance round the circle. The diameter of a circle is a straight line that touches two points on the circumference of a circle and also passes through the center.

Diameter = cirucumference / pi

396 ÷ 22/7 = 126 m

Complete question :

The 100m dah times in the girl's track meet were normally distributed with a mean of 13 seconds and a standard deviation of 0.3 seconds.

Lana finished the race in 13.2 seconds . If 84 other girls ran in the event, approximately how many runners did she beat?

Answer:

21 runners

Step-by-step explanation:

Mean, μ = 13 seconds

Standard deviation, σ = 0.3

Lana's race time = 13.2

We find the proportion of runners who had race time above 13.2 ;

Proportion of who had race tune above 13.2

P(x > 13.2)

Obtain the Zscore

Zscore = (x - μ) / σ

Z = (13.2 - 13) / 0.3

Zscore = 0.2 / 0.3 = 0.6667

P(Z > 0.6667) = 0.25239 (Z probability calculator)

This is about 0.25239 * 100 = 25.24% = 25% (nearest percent)

Hence, Number of runners Lana beat = 25% of total runners ;

0.25 * 84 = 21

Hence, Lana beat about 21 runners

Answer:

It will have 16 times more coverage than cell tower A.

The area of coverage from cell tower B is "16 times" greater than the area of coverage from cell tower A.

Given that cell tower A has a coverage radius of 42 miles, the radius of cell tower B is four times greater, which means it is 4 x 42 = 168 miles.

Now, let's calculate the areas of coverage for both towers:

Area of coverage from cell tower A = π (42)²

Area of coverage from cell tower B = π (168)²

To find out how many times greater the area of coverage from tower B is than tower A, we divide the area of coverage from tower B by the area of coverage from tower A:

Area ratio = (π (168)²) / (π (42)²)

= (168²) / (42²)

= (28224) / (1764)

≈ 16

Answer:

310.86

Step-by-step explanation:

310.86

The cylinder is a three-dimensional shape which have a circular base. The capacity of the cylindrical box is basically equal to the volume of the cylinder involved. The volume of the cylinder is 310.9 cubic inches.

The volume of a cylinder indicates the density of the cylinder which represents the amount of material it can carry or how much quantity of the material can be immersed in it. The volume of the cylinder is the product of the area of base and height.

The equation used to calculate the volume of the cylinder is:

Volume = π × r² × h

Here diameter = 6 inches

radius = 3 inches

Then volume is:

V = π × 3² × 11

V = 3.14 × 9 × 11

V = 310.86

Rounding to nearest ten, the value is V = 310.9 cubic inches.

Answer:

38 is the maximum value

Step-by-step explanation:

First we should graph each inequality. Then we can find the points on the intersecting region and take those points and plug them into the equation P = 4x + 5y. Then we can find the maximum value from there. The maximum value is tied to the point (7, 2), with P = 38. :)

Answer:

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle.

In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse).

In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos(θ) = adjacent / hypotenuse.

The tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle containing that angle. tangent=length of the leg opposite to the anglelength of the leg adjacent to the angle abbreviated as "tan"

Answer:

x = 5

Step-by-step explanation:

1/5(3x - 15) = -4(3/5x - 3)

Distribute the 1/5 in.

3x/5 - 3 = -4(3/5x - 3)

Distribute the -4 in.

3x/5 - 3 = -12x/5 + 12

Multiply both sides by 5.

3x - 15 = -12x + 60

Add 15 to both sides.

3x = -12x + 75

Add 12x to both sides.

15x = 75

Divide both sides by 15 to get

x = 5

Proof:

1/5(3x - 15) = -4(3/5x - 3)

1/5(3(5)-15) = -4(3/5(5) - 3)

1/5(15 - 15) = -4(3 - 3)

1/5(0) = -4(0)

0 = 0
