Answer:

3/10

Step-by-step explanation:

2,3,5 are the primes on the spinner so P(prime) = 3/5

probability of 'not heads' means P(tails) which equals 1/2

multiply the two probabilities 3/5 · 1/2 = 3/10

Answer: -6<x<5

Step-by-step explanation:

Given

Length is 3 m more than three times the width

Suppose width is x

So, the length is 3x+3

The area of a rectangle is  [tex]length\times width[/tex]

Area= [tex](3x+3)x<90[/tex]

[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]

Answer:

  (c)  5

Step-by-step explanation:

Put 4 where x is and do the arithmetic.

  F(4) = 3·4 -7 = 12 -7

  F(4) = 5

Given:

Principal value = 4580

Rate of interest = 6% apr compounded weekly

To find:

The total amount after 2 years.

Solution:

The formula for amount is

[tex]A=P\left(1+\dfrac{r}{100n}\right)^{nt}[/tex]

Where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.

1 year = 52 week

n=52

Putting P=4580, r=6, n=52, t=2 in the above formula, we get

[tex]A=4580\left(1+\dfrac{6}{100(52)}\right)^{52\times 2}[/tex]

[tex]A=4580\left(1+\dfrac{6}{5200}\right)^{104}[/tex]

[tex]A=4580\left(1+\dfrac{3}{2600}\right)^{104}[/tex]

[tex]A=4580\left(\dfrac{2603}{2600}\right)^{104}[/tex]

On further simplification, we get

[tex]A=4580(1.1274188)[/tex]

[tex]A=5163.5781[/tex]

[tex]A\approx 5163.58[/tex]

Therefore, the ending balance after 2 years is 5163.58.

Answer:

12/20

Step-by-step explanation:

Sandy orders 20 bread rolls for her party, and 3/5 of the rolls are whole wheat. What other fraction represents the part of rolls that are whole wheat?

The number of rolls that are whole wheat is calculated as:

3/5 × 20 bread rolls

= 12 wheat bread rolls

Hence, the other fraction thag represents the part of rolls that are whole wheat = 12 wheat bread rolls/20 bread rolls

= 12/20

Hey there! The answer to your problem is:

6 square units: rectangle PQRS, triangle TUV

8 square units: rectangle ABCD, triangle EFG

Answer:

what he said it right

Step-by-step explanation:

Answer:

Step-by-step explanation:

Based on similar triangle;

14/49 = x+5/9x+1

Cross multiply

49(x+5) = 14(9x+1)

49x + 245 = 126x + 14

49x - 126x = 14 - 245

-77x = -231

x = -231/-77

x = 3

Hence the value of x is 3

Answer:

7.632

Step-by-step explanation:

When solving this equation, you need to substitute the number equal to a where the a is in the equation, along with the b and c. So since a=0.32, then I would put that where the a is in 3ab+c. Same goes with the other letters.

a = 0.32

b = 0.45

c = 7.2

3ab+c

3(0.32)(0.45)+7.2 *Multiply the 3 to 0.32

0.96(0.45)+7.2 *Multiply the 0.96 to 0.45

0.432+7.2 *Add

7.632

Explanation:

Part A.

1. You have provided an estimate of 600 minutes per month.

__

2. The cheapest plan is likely to be Plan 6 (Public Mobile), as it has no per-minute charge.

__

Part B.

1. Table 2.

See the first attachment for Table 2. For the chosen plan, there is no per-minute charge, so the monthly charge is the same for all numbers of minutes.

__

2. Rate of Change and Slope (m)

a) Adding a minute adds $0 to the cost

b) The rate of change (m) is 0/1 = 0 (dollars per minute)

__

3. Initial value (b)

a) The plan costs $24.00 when no minutes are used.

b) The initial value (b) is 24.

__

4. Equation of the line

a) Filling the found values of m and b into the equation of the line, we have ...

  y = mx + b

  y = 0x + 24

  y = 24 . . . . . . simplified

__

Part C.

Table 3 can be found in the second attachment.

The b in each case is the value from the Monthly Cost column of Table 1.

The m in each case is the value from the Cost per minute column of Table 1.

The equation is found by copying the values of m and b into y = mx + b.

The number in the last column is found by multiplying the minutes (x) by m, then adding b. For example, your cost for Plan 5 (BELL) is ...

  y = 0.10x + 10

  y = (0.10)(600) +10 = 60 +10 = 70

Answer:

p=-17/9 or p=-1.8889

Step-by-step explanation:

-9p-17=10

add 17 to each side

-9p-17+17=10+17

-9p=17

divide both sides by -9

-9p/-9=17/-9

p=-17/9

or p=-1.8889

Solution of equation - 9p - 17 = 10 is p = -3.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation.

Given equation

- 9p - 17 = 10

Add 17 to both sides

- 9p - 17 + 17 = 10 + 17

Adding the numbers

- 9p = 10 + 17

Adding the numbers

- 9p = 27

Divide both sides by - 9

-9p/ - 9 = 27/ - 9

Cancel terms that are in both the numerator and denominator

p = 27/ - 9

Divide the numbers

p = -3

Hence, p = -3 is the solution for equation - 9p - 17 = 10
