Tamika records the outside temperature at 6:00 a.M. The temperature increases by 2ºF every hour for the next 6 hours. If the temperature continues to increase at the same rate, what will the temperature be at 2:00 p.M.?

Answers

Since the temperature taken at 6AM is not given, the answer is x + 16.

The temperature at 2 PM will be  x +16°F

What is temperature?

Temperature is a phrase used to describe the degree of heat or cold on any scale, including Fahrenheit and Celsius. A thermometer is used to determine temperature. It is calibrated using different temperature scales that historically defined themselves using different reference points and thermometric substances.

The most popular scales are the Celsius scale, also known as "centigrade," with the unit °C, the Fahrenheit scale, with the unit °F, and the Kelvin scale, with the unit K. The latter is primarily used for scientific research and is the primary temperature scale specified by the International System of Units (SI).

Let temperature at 6 AM be x°F

Time difference between 2 PM and 6 AM:

Δt = 14 -6

 = 8 hour

increase in temperature after every 1 hour = 2°F

increase in temperature in 8 hour will be:

ΔT = 2 * Δt = 2*8 = 16°F

Temperature at 2 PM will be = x + ΔT

                                                = x +16°F

The value of a, if The expression 2.4x − 3.9y − 1.2x + ay is equivalent to 1.2x + 1.2 y is 5.1.

What is an expression?

A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.

Given:

2.4x−3.9y−1.2x+ay is equivalent to 1.2x+1.2y,

2.4x − 3.9y − 1.2x + ay = 1.2x + 1.2y

Simplify the above expression as shown below,

2.4x − 1.2x + ay - 3.9y = 1.2x + 1.2y

1.2x + y(a - 3.9) = 1.2x + 1.2y

As the expression is equivalent, compare the expression as shown below,

a - 3.9 = 1.2

a = 1.2 + 3.9

a = 5.1

Thus, the value of a is 5.1.

Answer:

Step-by-step explanation:

When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number. You can also consider this with a number line.

Answers

1) x = 5y - 30  

2) x = - 1.6y + 3.3

im assuming these are 2 different questions

Explanation:1)

Start with the equation:

x - 5y= -30

add 5y to both sides:

x = 5y - 30

Your answer is x = 5y - 30  

2)

Start with the equation:

3x+5y=10

subtract 5y from both sides:

3x = -5y + 10

divide by 3 to get x singular

x = - 1.6y + 3.3

Your answer is x = - 1.6y + 3.3

A student earns Php 280.00 for a 5 hour shift on his summer job. The amount
of money he earns varies directly to the number of hours worked. Find the
constant k, and the amount of money he will earn for an 8-hour shift.

Answers

Answer:

y=k5, 448 after an 8 hour shift

Step-by-step explanation:

The amount of money he will earn for an 8-hour shift is Php448

Let the amount  of money he earns be A

Let the number of hours worked is "h"

If the amount  of money he earns varies directly to the number of hours worked is expressed as:

A = kx

k = A/x

GIven that A = Php 280.00, x = 5 hours

k = 280/5

k = 56

If x = 8 hours, the amount of money A = kx

A = 56 * 8

A = Php448

Hence the amount of money he will earn for an 8-hour shift is Php448

Can someone help me on 2/3-3/8 show work

Answers

Answer:

It is 7/24

Step-by-step explanation:

So first you want a common denominator so we have to find the least common multiple of 3 and 8, which is 24.

Next you have to multiply the same to the numerator, I usually go by the phrase whatever you do to the bottom you do to the top. So 8 times 2 is 16 and 3 times 3 is nine.

Everything changed should be 16/24-9/24

then we do 16-9 is 7 and you never subtract the denominators so 2/3-3/8 is 7/24

Tyler has a baseball bat that weighs 28 ounces. Find this weight in kilograms and in grams. Explain or show your reasoning. (Note: 1 kilogram 35 ounces)

Answers

Answer:

Weight in Kilograms = 0.8 Kilograms

Weight in grams = 800 grams

Step-by-step explanation:

Tyler has a baseball bat that weighs 28 ounces.

a) Weight in Kilograms

From the question:

1 kilogram = 35 ounces

Hence:

35 ounces = 1 kilogram

28 ounces = x kilogram

Cross Multiply

35 × x = 28 × 1

x = 28/35

x = 0.8 kilograms

b) Weight in grams

1 kilogram = 1000 grams

0.8 kilogram = x

Cross Multiply

x = 0.8 × 1000 grams

x = 800 grams
