Answer:

Therefore, the possible lengths (in whole inches) for the third side is

9 inches < x < 45 inches

Step-by-step explanation:

For the above question, we have a rule, the sum of the length of any two sides of the triangle must be greater than the length of the third side.

Hence:

She has two sides of length 18 inches and 27 inches

Let the third side = x

Hence:

a) 18 + 27 > x

45 > x

b) 18 + x > 27

x > 27 - 18

x > 9

Therefore, the possible lengths (in whole inches) for the third side is

9 inches < x < 45 inches

Answer:

0.12

Step-by-step explanation:

Probability is defined as the number of possible outcomes divided by the total outcome.

Given that 15% of the students drive to school and of  the students that drive to school, 80% are seniors then the probability a randomly selected  student drives to school and is a senior P(D&S)

= 15% * 80%

= 15/100 * 80/100

= 0.12

The 4th option

This question is based on the concept of probability. Therefore the correct option is (D), that is 0.12 is the probability a randomly selected  student drives to school and is a senior.

Given:

At a large high school, 15% of the students drive to school. Of the students that drive to school, 80% are seniors.

We have to calculated the probability a randomly selected  student drives to school and is a senior.

By the definition of probability,

Probability is  branch of mathematics, and it is defined as the number of possible outcomes divided by the total outcome.

Given that, 15% of the students drive to school and of  the students that drive to school, 80% are seniors.

Hence, the probability a randomly selected student drives to school and is a senior is ,

[tex]=\dfrac{15}{100} \times \dfrac{80}{100}\\\\= 0.15 \times 0.8\\\\= 0.12[/tex]

Therefore, the correct option is (D), that is 0.12 is the probability a randomly selected  student drives to school and is a senior.

Answer:

x > -18

Step-by-step explanation:

If x was -18, -18/3 is -6 and -6-6 is -12. So, x must be greater than -18.

Answer:

x>-18

Step-by-step explanation:

Inequality answers are same as algebra but we use < or > for more than or less than and with line under for equal to.

x/3 -6 >-12

x/3 > -12 +6

x/3 > -6

x>-6 x 3

x> -18

Answer:

A) No solution.

B) -2, 1, 2

C) 2, 1, - 2

D) Infinite number of solutions

Step-by-step explanation:

A) 2x + 5y - z = -2

3x - 2y + z = 4

-x + 7y - 2z = 2

Let's add eq(1) and eq(2) to eliminate z.

2x + 3x + 5y - 2y - z + z = -2 + 4

5x + 3y = 2 - - - (eq 4)

Let's multiply eq(2) by 2 and add to eq(3) to eliminate z.

6x - x - 4y + 7y + 2z - 2z = 8 + 2

5x + 3y = 6 - - -(eq 5)

Subtracting eq(4) from eq(5) gives;

0 = 4

This is inconsistent and thus the system of equation has no solution.

B) 4x + 5y + 3z = 3

-3x + 4y - z = 8

5x + 3y + 2z = -3

Multiply eq 2 by 3 and add to eq 1 to eliminate z;

4x - 9x + 5y + 12y + 3z - 3z = 3 + 24

-5x + 17y = 27 - - - (eq 4)

Multiply eq 2 by 2 and add to eq 3 to eliminate z;

5x - 6x + 3y + 8y + 2z - 2z = -3 + 16

-x + 11y = 13 - - - (eq 5)

Multiply eq (5) by -5 and add to eq 4 to get;

17y - 55y = 27 - 65

-38y = - 38

y = 1

Putting 1 for y in eq 5 gives; x = -2

Putting x = - 2 and y = 1 in eq 1 gives;

z = 2

C) 4x - 3y + 2z = 1

-2x + 3y - 2z = 3

2x - 3y + 3z = -5

Solving this equation simultaneously via a calculator gives;

x = 2, y = 1, z = - 2

D) 2x + 3y - z = -2

x - 9y + 2z = 8

-x - 12y + 3z = 10

Add eq(2) to eq (3) to get;

-21y + 5z = 18 - - - (eq 4)

Multiply eq 2 by 2 and add to eq 3 to get;

-30y + 7z = 26 - - - (eq 5)

From eq 4, z = (18 + 21y)/5

Put this in eq 5 to get;

-30y + 7(18 + 21y)/5 = 26

-30y + 126/5 + 147y/5 = 26

Solving this leads to infinite number of solutions

Step-by-step explanation:

In 1 ounce there are 5 piece of Candy.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

There are 75 pieces of candy in a 15 oz bag.

So, Per ounce the amount of candy

= 75/ 15

= 5

Hence, In 1 ounce there are 5 piece of Candy.

Hi how are you doing today

Answer:

159 text messages

Step-by-step explanation:

Given that:

Predicted average = 2042

Number of months = 6

Number of texts for each of last 5 months :

Let number of text that must be sent in the sixth month = x

Predicted Average = (sum of texts / Number of months)

2042 = (2800 + 2481 + 2105 + 1975 + 2732 + x) / 6

2042 = (12093 + x) / 6

Cross multiply :

6 * 2042 = 12093 + x

12252 = 12093 + x

x = 12252 - 12093

x = 159

Answer:120

Step-by-step explanation:

Given:

f(x) is an exponential function.

[tex]f(2.5)=26[/tex]

[tex]f(6.5)=81[/tex]

To find:

The value of f(12), to the nearest hundredth.

Solution:

The general exponential function is

[tex]f(x)=ab^x[/tex]

For, x=2.5,

[tex]f(2.5)=ab^{2.5}[/tex]

[tex]26=ab^{2.5}[/tex]          ...(i)

For, x=6.5,

[tex]f(6.5)=ab^{6.5}[/tex]

[tex]81=ab^{6.5}[/tex]          ...(ii)

Divide (ii) by (i).

[tex]\dfrac{81}{26}=\dfrac{ab^{6.5}}{ab^{2.5}}[/tex]

[tex]\dfrac{81}{26}=b^4[/tex]

Taking 4th root on both sides, we get

[tex]\sqrt[4]{\dfrac{81}{26}}=b[/tex]

[tex]b\approx 1.32855[/tex]

Putting b=1.32855 in (i), we get

[tex]26=a(1.32855)^{2.5}[/tex]

[tex]26=a(2.03444)[/tex]

[tex]\dfrac{26}{2.03444}=a[/tex]

[tex]a\approx 12.7799[/tex]

Now, the required function is

[tex]f(x)=12.7799(1.32855)^x[/tex]

Putting x=12, we get

[tex]f(12)=12.7799(1.32855)^{12}[/tex]

[tex]f(12)=386.4224[/tex]

[tex]f(12)\approx 386.422[/tex]

Therefore, the value of f(12) is 386.422.
