Answer: [tex]\dfrac{15}{4}[/tex]

Step-by-step explanation:

Given

[tex]\Rightarrow \dfrac{3}{k}=\dfrac{4}{5}[/tex]

Apply cross-multiplication

[tex]\Rightarrow K=3\times \dfrac{5}{4}=\dfrac{15}{4}\\\\\Rightarrow k=3\ \dfrac{3}{4}[/tex]

The value of k is [tex]\dfrac{15}{4}\ \text{or}\ 3\ \dfrac{3}{4}[/tex]

Answer:

15/4

Step-by-step explanation:

Answer:

The reasonable prediction for successful rolls is 4.

Step-by-step explanation:

Assuming the rolling cube  is a fair 6 sided cube, so the probability of success of one roll is given as

[tex]P(Success)=\dfrac{Number\ of\ successful\ events}{Number\ of\ total\ events}[/tex]

[tex]P(Success)=\dfrac{1}{6}[/tex]

The total success is given as

[tex]P(Total\ Success)=P(Success)\times Number\ of\ events[/tex]

For 24 rolls it is given as

[tex]P(Total\ Success)=P(Success)\times Number\ of\ events\\P(Total\ Success)=\dfrac{1}{6}\times 24\\P(Total\ Success)=4[/tex]

So the reasonable prediction for successful rolls is 4.

Given:

The side of the square = [tex]9\sqrt{6}[/tex] m

To find:

The diagonal of the square.

Solution:

We know that the diagonal of a square is:

[tex]d=a\sqrt{2}[/tex]

Where, d is the length of diagonal and a is the side of the square.

Putting [tex]a=9\sqrt{6}[/tex], we get

[tex]d=9\sqrt{6}\sqrt{2}[/tex]

[tex]d=9\sqrt{12}[/tex]

[tex]d=9(2\sqrt{3})[/tex]

[tex]d=18\sqrt{3}[/tex]

Therefore, the diagonal of the square is [tex]18\sqrt{3}[/tex] m.

Answer:

113.14 is the answer use circle formula

Graham needs to pick 10 more oranges to have the same amount I think

Step-by-step explanation:

so first multiply 5 and 12 which is 60

5*12=60

then divide 60 from 6 or 6 from 60

60÷6= 10

Answer:

[tex]c = 11[/tex]

Step-by-step explanation:

Given

Let the three sides be a, b and c

Such that:

[tex]a = b= 5[/tex]

Required

Find c such that a, b and c do not form a triangle

To do this, we make use of the following triangle inequality theorem

[tex]a + b > c[/tex]

[tex]a + c > b[/tex]

[tex]b + c > a[/tex]

To get a valid triangle, the above inequalities must be true.

To get an invalid triangle, at least one must not be true.

Substitute: [tex]a = b= 5[/tex]

[tex]5 + 5 > c[/tex] [tex]===>[/tex] [tex]10 > c[/tex]

[tex]5 + c > 5[/tex]  [tex]===>[/tex] [tex]c > 5 - 5[/tex] [tex]===>[/tex] [tex]c > 0[/tex]

[tex]5 + c > 5[/tex]  [tex]===>[/tex] [tex]c > 5 - 5[/tex] [tex]===>[/tex] [tex]c > 0[/tex]

The results of the inequality is: [tex]10 > c[/tex] and [tex]c > 0[/tex]

Rewrite as: [tex]c > 0[/tex] and [tex]c < 10[/tex]

[tex]0 < c < 10[/tex]

This means that, the values of c that make a valid triangle are 1 to 9 (inclusive)

Any value outside this range, cannot form a triangle

So, we can say:

[tex]c = 11[/tex], since no options are given

Answer:

[tex]x = 7 \sqrt{2} [/tex]

Step-by-step explanation:

[tex]sinθ = \frac{opp}{hyp} [/tex]

[tex]sin45° = \frac{7}{x} [/tex]

[tex] \frac{ \sqrt{2} }{2} = \frac{7}{x} [/tex]

Cross multiply:

[tex]( \sqrt{2} )(x) = 7(2)[/tex]

[tex]x = \frac{14}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } [/tex]

[tex]x = \frac{14 \sqrt{2} }{2} [/tex]

[tex]x = 7 \sqrt{2} [/tex]

Answer:

8.7

Step-by-step explanation:

Add up all the books

5 students have 6 books each

3 students have 8 books each  and so on

5 * 6 = 30

8*3 =24

9*6 = 54

12*4 = 48

-------------

156 books

Divide by the number of students

156/18 =8.6666666

Round to the nearest tenth

8.7

The average ( or mean) number of books per student is 8.7 books

Answer:

x= -1

Step-by-step explanation:

p= x² +4x -2 -----(1)

q= 2x -1 ------(2)

q -p= 2 -----(3)

Substitute (1) and (2) into (3):

2x -1 -(x² +4x -2)= 2

2x -1 -x² -4x +2= 2 (Expand bracket)

-x² -2x +1=2 (Simplify)

x² +2x +2 -1= 0 (Bring all terms to one side)

x² +2x +1= 0

(x +1)²= 0 (Factorise)

x +1= 0 (Square root both sides)

x= -1 (-1 on both sides)

Answer:

There is a 9/10 probability that the marble will not be yellow.

Step-by-step explanation:

If there are a total of ten marbles, and there is one yellow marble, there is a

1 yellow marble / 10 total marbles chance of getting a yellow marble. Then subtract it from 10/10 to get the probability of NOT getting a yellow marble.

10/10 - 1/10 = 9/10.

Answer:

9/10

Answer:

15.7 units²

Step-by-step explanation:

The sector area is 50/360 times the area of the circle (since the central area of a complete circle is 360° and that for the sector is 50°), or

Sector area = (50/360)(3.14)(6 units)² = 15.7 units²

Answer:

From left to right:

90°  (clockwise or counterclockwise)

45°  (clockwise or counterclockwise)

72°  (clockwise or counterclockwise)

Step-by-step explanation:

360/4 = 90°

360/8 = 45°

360/5 = 72°
