what's the error in this problem pls help im being timed

Answer:

2 is your right answer ok my friend

Answer:

1. 4y-12

2. c

For #1 you distribute the 4 to the y and the 3. 4 times 3 equals 12.

For #2 you factor out the 3 and you get 3(5x+1)

Answer:

4y-12

Step-by-step explanation:

Multiply the outside number by the numbers in the bracket.

Example:4×y=4y Because y=1

4×3=12

2.Answer C

3(5x+1)

3×5x=15x

3×1=1

Which is equivalent to 3(5x+3)

Hope this helps.

The requried range of the radio station is given as 1256 square miles.

The area of the circle is given by the pie times square of the radius.
A = πr², where r is the radius of the circle.

Here,
A small radio station can broadcast in a circular range with a radius of 20 miles.
The range is given by the area of the circle with given radius,
Area of the circle = πr²
Area of the circle = 3.14 × 20²
area of the circle = 1256 square miles

Thus, the requried range of the radio station is given as 1256 square miles.

#SPJ2

Answer:

option A is correct

it is given. r= 6 and t = 8

r^2+ 4t -5 = 63

6*6 + 32 -5 = ? hope it helps

36 +32 - 5 = ??

= 63

Answer:

130°

Step-by-step explanation:

50 + x = 180°

Answer:

Opposite 50 would be 50 because they are parallel X which is corresponding to each other and the other two angles will be even as well because they are also corresponding

In a circle theres 360 degrees and 50+50=100

360-100=260 divide by 2 is 130

divide by two because of the two other missing angles.

your answer is 130°

Complete question :

Mavis is interested in whether military dependency is related to gender in American Samoa. Here is data she collected about the population of American Samoa in 2010.

Millitary status _________ female ____ Male

In armed forces _________ 28 _______ 59

Millitary dependent ______ 928 ______ 781

Civilian _______________ 26393 ___27330

Answer:

Male = 0.4193

Female = 0.5087

Step-by-step explanation:

To obtain the marginal distribution of gender :

Total number of civilians (male + female)

(26393 + 27330) = 53,723

Male :

P(male) = number of male / total

P(male) = 26393 / 53,723 = 0.4912793

P(Female) = number of Female / total

P(Female) = 27330 / 53,723 = 0.5087206

Answer:

2=41     1=49      3=49

Step-by-step explanation:

Angle 2 = 41 because it is directly across the given angle.

Angles 1 and 3 are equal, and the total number of degrees in the rombus are 180.

41+41=82

180-82=98

98 / 2 = 49

Angles and 3 both equal 49

Answer:

2=41°(Alternate Interior angles)

1=41°(diagonal of rhombus bisects the interior angles)

3=49°(180-82/2)

Answer:

1260 ways

Step-by-step explanation:

Given

[tex]Dolls = 8[/tex]

[tex]Boxes = 5[/tex]

From the question, we understand that: the boxes are identical; however, the dolls are different.

Since no box can be empty, the following scenario exists:

2, 2, 2, 1, 1

This means that 3 of the 5 boxes will hold 2 dolls each while the other 2 will hold 1 doll each.

 So, the number of selection is as follows:

2 of the 8 dolls will be selected in 8C2 ways

2 of the remaining 6 dolls will be selected in 6C2 ways

2 of the remaining 4 dolls will be selected in 4C2 ways

1 of the remaining 2 will be selected in 1C1 ways

1 of the remaining 1 will be selected in 1C1 ways

[tex]Expression: ^8C_2 * ^6C_2 * ^4C_2 * ^1C_1 * ^1C_1[/tex]

Since the boxes are identical, we have to divide the above expression by 2 to get the number of ways:

[tex]Ways = \frac{^8C_2 * ^6C_2 * ^4C_2 * ^1C_1 * ^1C_1}{2}[/tex]

[tex]Ways = \frac{28 * 15* 6* 1 * 1}{2}[/tex]

[tex]Ways = \frac{2520}{2}[/tex]

[tex]Ways = 1260[/tex]

Answer: 1,200 ml

Step-by-step explanation:

The ratio is 1 : 5.

If 200 ml of concentrate is used, the water used will be:

1     :    5

200 :   x

x = 1,000 ml of water

The amount of juice would be:

= water + concentrate

= 1,000 + 200

= 1,200 ml

Answer:

t = 1 s

Step-by-step explanation:

The function models the height of the ball after t seconds is given by :

[tex]h=32t - 16t^2[/tex]

We need to find how many seconds does it take for the ball to reach its maximum height.

For maximum height put dh/dt = 0

[tex]\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t[/tex]

So,

32-32t = 0

t = 1

So, it will take 1 second to reach its maximum height.

Answer:

Step-by-step explanation:

Find the diagram attached

Area of a parallelogram = Base * Height

Given

Area = 120ft^2

BAse = 20ft

Required

Height

From the formula;

Height = Area/Base

Height = 120/20

Height = 6ft

Hence the value of h is 6ft

Answer:

0.9937

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

12x + 15 = 5x +  85   {Subtract 15 from both sides}

12x + 15 - 15 = 5x + 85 - 15  

          12x = 5x + 70        {Subtract 5x from both sides}

12x - 5x   = 70

         7x = 70         {Divide both sides by 7}

          x = 70/7

x = 10

∠U = 5x = 5*10 = 50
