Answer:

Step-by-step explanation:

On this one you would eliminate the ones that are negative or that go into a negative. Which would be A,C, and E. The rest that are left are zero or positive. B for example is a zero because eventually there will be no candle. D would be the same in some way, the students will eventually leave the school. Finally F, the temperature would be increasing.

Answer - B,D,F

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

Answer:

interior angle of a heptagon = 900 degrees

900 = 4x + (3x + 60)

840 = 7x

840/7 = 120

X = 120

120 X 4 = 480

120 X 3 = 360

480 + 360 + 60 = 900

4 angles = 120 degrees each

3 angles = 140 degrees each

Answer:

They are used to share something among friends , Like if there are four friends and they want to divide a cake equally among themselves , then the quantity of cake that each friend will get will be one-fourth of the cake , That is a rational number 1/4.

Step-by-step explanation:

short answer it won't trust me

The number of red cells are 4 and the number of blue cells are 8. Then the correct option is C.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

In the grids, there are 12 square box.

Let R be the red and B be the blue.

R + B = 12   ...1

R / B = 1/2  ...2

By solving equation 1 and 2, we have

R + 2R = 12

      3R = 12

        R = 4

Then  

4 + B = 12

     B = 8

Then the correct option is C.

Answer:

a=5.1

Step-by-step explanation:

Isolate the variable by dividing each side by the factors that don't contain the variable. Hope this helps! :)

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.

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.

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

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

Answer:

24 is the lcd for 6 and 8..

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

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.

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
