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.

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

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:

9.6 ounces

Step-by-step explanation:

Step 1

We find the amount of ounces of Almonds

Total amount of nuts in the container = 24 ounces

0.20 of the nuts are almonds.

Hence,

The amount of almonds = 0.20 × 24 ounces

= 4.8 ounces

Step 2

We find the amount of ounces of hazelnuts

Total amount of nuts in the container = 24 ounces

0.20 of the nuts are hazelnuts.

Hence,

The amount of hazelnuts = 0.20 × 24 ounces

= 4.8 ounces

Step 3

Therefore, the total amount of almonds and hazelnuts in the can is

4.8 ounces + 4.8 ounces

= 9.6 ounces

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:

the lateral surface area of a cone is 35π inches^2

Step-by-step explanation:

Given that

The diameter is 7 inches

And, the slant height is 10 inches

We need to find out the lateral surface area of the cone

We know that

The Lateral surface area of the cone is

= πrl

= π × 7.5 ÷ 2 × 10

= 35π inches^2

Hence, the lateral surface area of a cone is 35π inches^2

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

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:

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:

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.

i dont under stand number 4 but ur welcome

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.
