3 hours. ......i think. ..........

Answer:

2/15

Step-by-step explanation:

2 green pens, 3 blue pens, 4 red pens, and 1 black pen =10 pens

P(red) = red/total = 4/10 = 2/5

Keep the pen

2 green pens, 3 blue pens, 3 red pens, and 1 black pen =9 pens

P(red) = red/total = 3/9 = 1/3

P(red,red) = 2/5 * 1/3 = 2/15

Answer:

The blue dot is located at -3

Answer: 43046721(t^8)

Step-by-step explanation:

So first, multiply 3 by t to get 3t. Then, multiply it again by 3 to get 9t. Raise it to the 8th power to get (9^8)(t^8). This gives you 43046721(t^8)

Answer:

9/14

Step-by-step explanation:

3/8 * 3/7 * 4/1

~Multiply

9/56 * 4/1

~Multiply again

36/56

~Simplify

9/14

Best of Luck!

Answer:9/14

Step-by-step explanation:

3/8×3/7=9/56

9/56×4/1

(divide the 56 by 4 and the 4 by 4)

9/14 × 1/1 = 9/14

Answer:

Step-by-step explanation:

[tex]a = \frac{2b+1}{3b-1}[/tex]

b = 2/3

[tex]2b + 1 = 2*\frac{2}{3}+1\\\\=\frac{4}{3}+1\\\\=\frac{4}{3}+\frac{3}{3}\\\\=\frac{7}{3}\\\\3b-1 = 3*\frac{2}{3}-1\\\\=2- 1 = 1\\\\\\[/tex]

[tex]a = \frac{2b+1}{3b-1}\\\\a=\frac{\frac{7}{3}}{1}\\\\=\frac{7}{3}\\\\[/tex]

a = 7/3

b)

[tex]\frac{2b+1}{3b-1}=a\\\\[/tex]

Cross multiply,

2b + 1 = a*(3b - 1)

2b + 1 = a*3b - 3*a

2b + 1 = 3ab- 3a

2b = 3ab - 3a - 1

2b - 3ab = -3a  - 1

b(2 - 3a) = -3a - 1

[tex]b =\frac{-3a - 1}{2 - 3a}[/tex]

Answer:

The evening temperature is 4° F

Step-by-step explanation:

6° F below 0 =  -6.

15° F. -6 + 15 is 9.

9° F. 5° F. 9 - 5 = 4

Answer:

No.

Step-by-step explanation:

If I multiplied 2 by 9 to get 18, I would have to do the same to the 1. This would make the ratio 9:18, not 13:18.

Therefore, these two ratios are not equivalent.

Step-by-step explanation:

Find the square of 4100 by long division method

As 4100 is not a perfect square, it will have balance.

Now Find 65 * 65 = 4225

4225 - 4100 = 125

125 should be added to 4100 to get a perfect square

4225  = 5 * 5 * 13 * 13

[tex]\sqrt4225}=\sqrt{5*5*13*13}=5*13=65[/tex]

Nearest square of 4100.

[tex]\\ \sf\longmapsto 4225-4100[/tex]

[tex]\\ \sf\longmapsto 125[/tex]

125 should be added

hi

it a cube so it's height,length and width are the same.

if volume is 112 so one if this measure is : 112^(1÷3) =4,82

Answer:

The answer is A

Step-by-step explanation:

It has to exceed not be same or equal to

Answer:

C

Step-by-step explanation:

Im pretty sure its c, i took this test not too long ago.

Answer:

dissect the trapezium into a square and triangle. since the triangle is a right angled one the base is 17-7=10cm

the height is found using Pythagorean theorem to be 24cm i.e 26²=x²+10²,x=√(676-100),x=√576,x=24cn

area of trapezium is (1/2)(a+b)h

a is the shorter side and b the longer side

(1/2)*(7+17)24

=288cm²

Answer:

y = 3x+6

Step-by-step explanation:

refer to the picture

Answer:

y = 3x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, so slope of parallel line is 3

Expressing the equation in point- slope form with m = 3 , (x₁, y₁ ) = (1, 9)

y - 9 = 3(x - 1)

y - 9 = 3x - 3 ( add 9 to both sides )

y = 3x + 6 ← in slope- intercept form

Request : Please mark it brainliest answer

Answer:

71 boxes

Step-by-step explanation:

1. Add 522 (# of glaze donuts) and 323(# of chocolate covered donuts).....845(# of total donuts)

2. Divide 845 by 12(the # of donuts each box could hold)....70.41666(repeating)

3. As you can't have a 0.41666 of a box, you round up 70.4166666 to 71.

71*12=852 70*12=840

Even though 71 boxes is more than enough to hold 845 donuts, there is simply no other choice, as there is no smaller box that holds less than 12 donuts.

[tex]Volume =\frac{4}{3}\pi r^{3}\\\\=\frac{4}{3}\pi (4)^{3}[/tex]

Answer:

V = 4/3 pi (4)^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The radius is 4

V = 4/3 pi (4)^3

Answer:

the answer is 1/2 which loos like "D"

Step-by-step explanation:

the top ends up being x ^-8 and the denominator is x^-7

which is x^&/x^8 = 1/x = 1/2

Answer:

slope : -1, y-intercept : 13

Step-by-step explanation:

-x = -1 times x

+13 = 13 = y-intercept

Answer:

This equation is in slope intercept form, y=mx+b, where m is the slope and b is the y intercept.

So, the slope is -1 and the y intercept is 13.
