Answer: 1 1/6

Step-by-step explanation: i dont know if this is right, but hope it helps

Answer:

1 1/6

Step-by-step explanation:

Given function:

find the three beehives honey Lila total collected2/3,1/4,1/4

Combine the terms:

[tex]\frac{2}{3}+\frac{1}{4}+\frac{1}{4}=\frac{2}{3}+\frac{2}{4}[/tex]                    

Simplfly the fraction terms:

[tex]\frac{2}{3}[/tex]·[tex]4=\frac{8}{12}[/tex] [tex]\frac{2}{4}[/tex]·[tex]3=\frac{6}{12}[/tex]

Combine the terms:

[tex]\frac{8}{12}+\frac{6}{12}=\frac{14}{12}[/tex]

Simplifly the final value:

[tex]\frac{14}{12}=1\frac{2}{12}[/tex] [tex]1\frac{2}{12}=1\frac{1}{6}[/tex]

The perimeter of a triangle is34 ft. One side of the triangle is 2 times the second side. The third side is 6 ft longer than the second side. Find the length of each side

Answers

Let the second side = x

The first side is 2x ( 2 times the second side)

The third side is x + 6 ( 6 feet longer than the second side)

Now you have: x + 2x + x + 6 = 34

Simplify to get:

4x + 6 = 34

Subtract 6 from both sides

4x = 28

Divide both sides by 4:

X = 7

1st side = 2x = 2*7 = 14 feet

2nd side = x = 7 feet

3rd side = x + 6 = 7 + 6 = 13 feet

Let x equal the amount of money he/she started with (The pronouns change in the question.)

1/3x + 1/5x = 32
We need a common denominator to add the fractions. We’ll use 15.
5/15x + 3/15x = 32
8/15x = 32
Multiply both sides by 15/8, or multiply by 15, then divide by 8, if that is easier to understand.
8x = 480
x = 60

He/she started with $60.

Let’s check the math:
1/3 of $60 is $20
1/5 of $60 is $12
$20 + $12 = $32.

Answers

Answer: aA 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years = (0.163,0.189)

Step-by-step explanation:

Let p = population proportion of adults in the U.S. who have donated blood in the past two years.

Given: A Gallup survey of 2322 adults (at least 18 years old) in the U.S. found that 408 of them have donated blood in the past two years.

Sample size: n= 2322

Sample proportion [tex]q=\dfrac{408}{2322}=0.176[/tex]

In ΔPQR, p = 75 inches, q = 73 inches and r=35 inches. Find the measure of ∠P to the nearest 10th of a degree.

Answers

Answer:

79.5

Step-by-step explanation:

a^2 =b^2+ c^2-2bc cos A

cos p = 73^2+35^2-75^2/2(73)(35)

cos p= 9229/5110

cosp=79.5

The measure of ∠P to the nearest 10th of a degree is 79.5

What is a cosine law?

Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.

u² = s² + t² - 2(s)(t)·cos U

We are given that In ΔPQR, p = 75 inches, q = 73 inches and r=35 inches.

u² = s² + t² - 2(s)(t)·cos U

Now substituting;;

cos p = 73²+35²-75² /2(73)(35)

cos p= 9229/5110

cosp=79.5

The measure of ∠P is 79.5

5x + 80 = 180

5x = 180 - 80

5x = 100

x = 20

does anyone know how to solve this? ​ I have to find lengths FJ, DM, and EM

Answers

Answer:

FJ= 24

DM= 16

EM= 18

Step-by-step explanation:

The centroid is twice as close along any median to the side that the median intersects as it is to the vertex it emanates from.

So in the case of FJ, the median intersects the side at point J and extends from vertex F. This means that FM is twice as long as MJ. It tells us that MJ is 8, so MF would be 16. Now because FJ is just FM+MJ, FJ is 24.

It also tells us that DK is 24, which means that DM+MK = 24. If DM is twice as long as MK, that would make MK equal to 8 and DM equal to 16

Similarily, EM would be twice as long as ML. It says that ML=9 so that would make EM=18

Answers

Answer:

  164π cm²

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr²

The radius (r) is half the diameter (d), so the area of a semicircle in terms of its diameter is ...

  1/2A = (1/2)(π)(d/2)² = (π/8)d²

The given shape is the combination of three (3) semicircles. The smallest has a diameter of 6 cm; the middle-sized one has a diameter of (32 cm -6 cm -8 cm) = 18 cm. The largest has a diameter of 32 cm.

The total area will be ...

  area of largest + area of middle-size - area of smallest

  = (π/8)(32² +18² -6²) = (π/8)(1312) . . . . cm²

The area of the shape is 164π cm².
