EMERGENCY A speeding ticket costs $80 plus $10 for each mile per hour over the speed limit the violator was traveling. How much would someone going 12 miles per hour faster than the speed limit have to pay for their ticket?

Answer:

Step-by-step explanation:

To find value:

2x + 3z

Given values:

x = 4, y = 3 and z = -2

Solution:

2x + 3z

(Putting the values of x = 4 and z = -2)

= 2(4) + 3(-2)

= 8 - 6

= 2 (Ans)

Answer:

2

Step-by-step explanation:

2×4+3×−2

=8+3×−2

=8+−6

Step-by-step explanation:

The correct conversion is 68°F = 20°C.

Conversion is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We are given that;

To convert 68°F

Now,

To solve the formula for C, we need to isolate C on one side of the equation. We can do this by subtracting 32 from both sides and then dividing by 1.8. The steps are:

F = 1.8C + 32

F - 32 = 1.8C

(F - 32) / 1.8 = C

Therefore, the correct formula for C is:

C = (F - 32) / 1.8

To convert 68°F to degrees Celsius, we can plug in F = 68 into the formula and simplify. The steps are:

C = (68 - 32) / 1.8

C = 36 / 1.8

C = 20

Therefore, after conversion the answer will be 68°F = 20°C.

Step-by-step explanation:

the first brand = (65-55)/(80-55) x 180

= 10/25 × 180

= 72 gallons

the second brand = (80-65)/(80-55)×180

= 15/25 × 180

= 108 gallons

The student did not distribute properly to get A= P+Prt. The equation can be fixed by putting a factor of P in the denominator: r=(A-P)/Pt

Step-by-step explanation:

There is an error in step 2 where distributive property was not followed.

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Steps taken by the student to solve the formula of the simple interest for the values of '',

Step 1 : A = P( 1 +rt)

Step 2 : A = P + rt

Step 3 : A - p = rt

Step 4 : r = (A - P)/ t

There is an error in step 2 where distributive property was not followed.

Correct steps should be,

Step 1 : A = P( 1 +rt)

Step 2 : A = P + Prt [By distributive property]

Step 3 : A - P = Prt

Step 4 : r = (A-P)/Pt

Therefore, error was made in step 2.

Answer: Therefore, his son and daughter got Rs 200.

Step-by-step explanation:

6 kg of rice = 75*6 = Rs 450

2 packets of oil = RS 2*125 = RS 250

now total money he spent = Rs 450 + Rs 250 + Rs Rs 3,300

                                             = Rs 700 + Rs 3,300

                                             = Rs 4000

Money left = Rs 4,400-Rs 4000 = Rs 400

so

400/2 = Rs 200

Step-by-step explanation:

Answer:

the cost continues to increase

Step-by-step explanation:

the cost (C) approaches infinity (or becomes very large) as t approaches 100%. Thus, the correct answer is: A. The cost continues to increase.

To determine what happens to the cost (C) as t approaches 100%, we can take the limit of the cost function as t approaches 100.

The cost function is given as: [tex]\[ C = \frac{55,000t}{100 - t} \][/tex]

Now, let's find the limit of C as t approaches 100:[tex]\[ \lim_{{t \to 100}} C = \lim_{{t \to 100}} \frac{55,000t}{100 - t} \][/tex]

To find this limit, we can use direct substitution:[tex]\[ \lim_{{t \to 100}} \frac{55,000 \times 100}{100 - 100} = \lim_{{t \to 100}} \frac{5,500,000}{0} \][/tex]

Since the denominator approaches 0 as t approaches 100, the limit is undefined (infinite).

Therefore, the cost (C) approaches infinity (or becomes very large) as t approaches 100%. Thus, the correct answer is: A. The cost continues to increase.

Answer:

Step-by-step explanation:

To get equivalent expressions, if you are adding or subtracting, the number and letter you get on the left must be the same as the one on the right.

In B. The answer is incorrect because 4t is minus on the left. The letters are different, so 4t must remain minus. Not B

In C the numbers will combine when you add. If they are the same,, they remain the same. They do not become powers the answer for C is 10s. So C is not correct.

In D you are indicating that 6 is multiplied by 4s.  You can only multiply 6 and 4. They don't add. Not D

Hope it helps:)

Josh starts with 8/8 (or any other fraction that equals 1) of his allowance. He then spends 3/8 of it.

8/8 x 3/8 = 3/8

8/8 - 3/8 = 5/8

He spend 3/8 of his allowance, leaving him with 5/8 left. Then Josh spent 2/3 of that remaining amount.

5/8 x 2/3 = 10/24 = 5/12

Josh has 5/12 of his allowance left for the rest of the week.

Hope this helps!
