On January 22 in 1943, the town of Spearfish, South Dakota, set the record for the world’s fastest temperature change.



At 7:30 a.m., the temperature was `-4`°F.

By 7:32 a.m., the temperature was `45`°F.

By 9:00 a.m. the same day, the temperature was `54`°F.

By 9:27 a.m., the temperature was `-4`°F.



How many degrees did the temperature change each minute from 7:30 to 7:32?

Answer:

Yes.

Step-by-step explanation:

The expression 2y + 6 could be used to denote the tree's height.

A number, a variable, or a mixture of numbers and variables, along with operation symbols, make up an expression. Two expressions joined by an equal sign form an equation.

Given, the height of a tree that began at 6 feet and increases by 2 feet per year. Let y represent the number of years

Expression = 2y + 6

Since the height of the tree starts at 6 feet thus positive 6 would be constant and it increases by 2 feet every year thus 2 would be the multiple of the variable that is y.

therefore, an Expression that represents the height of the tree would be 2y + 6.

Answer:

C

Step-by-step explanation:

the "-" sign can't be true, because that would have turned the whole graph of x² upside-down. but it is not.

so, we need a positive sign for the x term.

and the whole graph is shifted to the right. so the functional value of x of F(x) is now the same that happened "earlier" (for smaller x) with G(x). so, the argument "x" is now reduced (by 3 units, as the graph is shifted right by 3 units) in the calculation compared to the original G(x) calculation.

therefore, the ...(x-3)... expression is right.

so, positive sign and "(x-3)" is only in C.

Answer:

123 + (456 + 789)

Step-by-step explanation:

since this is an addition problem, the parenthesis don't matter, and they can be put wherever you want.

(123 + 456) + 789

123 + 456 + 789

(123 + 456 + 789)

123 + (456 + 789)

technically, any of these would work, but I think the kind of answer the problem is looking for is;

123 + (456 + 789)

Answer:

Step-by-step explanation:

Let the larger number = x

Smaller number = y

6x + 7y = 114 ------------(I)

10x - 9y = 66 ------------(II)

Multiply equation (I) by 9 and multiply the equation (II) by 7. After that add the two equations. So that, y will be eliminated and we can find the value of x

         (1)*9        54x + 63y = 1026

         (II)*7        70x - 63y  =  462    {Now add}

                        124x           = 1488   {Divide both sides by 124}

                                        x = 1488/124

x = 12

Plugin x =  12 in any of the equation. Here, We are substituting in  equation (I)

6*12 + 7y = 114

  72 + 7y =114

         7y = 114 - 72

         7y = 42

          y = 42/7

y = 6

The numbers are 12 , 6

Answer:

x = 49

Step-by-step explanation:

Since the line is parallel, the value of 2x - 8 is equal to 90.

=> 2x - 8 = 90

=> 2x = 98

=> x = 49

Answer:

x = 49

Step-by-step explanation:

2x - 8 and the right angle are corresponding angles and are congruent , then

2x - 8 = 90 ( add 8 to both sides )

2x = 98 ( divide both sides by 2 )

x = 49

Answer:

277 591.1 ft³

Step-by-step explanation:

First, use the formula for circumference to solve for the diameter.

Circumference = πd

295.3 = πd

295.3/π = d

94 ft = d

Then, divide the diameter by 2 to find the radius.

r = d/2

r = 94/2

r = 47 ft

Now, use the value of the radius with the given height in the formula for volume of a cylinder.

V = πr²h

V = π(47²)(40)

V = 277 591.1 ft³

Answer:

first we need to add all of the swans together, then from there you take the amount of mute swans and divide it by the sum of all the swans! finally, multiply by 100 to convert into a percent and round it to 12.2%

Step-by-step explanation:

Answer:

8%

Step-by-step explanation:

First, add the total of all the swans together

5+34+2=41

Next, take the total and divide it by the number of mute swans there are

41÷5=8.2

Finally round 8.2 to the nearest whole percent

8.2=8

The answer is 8%

Answer:

105

Step-by-step explanation:

Assuming A^2 + B^2 = C^2:

C^2 = 4 + 3 = 7

So,

C^2 * 15 = 49(15) = 105

Note: Since the relationship between A, B, and C isn't known, it cannot be said for certain that 105 is the answer.

Step-by-step explanation:

there is no C in the first 2 equations. There is no A or B in the last expression. I do not think you can solve this.

75 = 3 x 25 = 3 x 5²

32 = 2 x 16 = 2 x 4²

68 = 4 x 17 = 2² x 17

So

the largest perfect square number that is a factor of 75 is 25

the largest perfect square number that is a factor of 32 is 16

the largest perfect square number that is a factor of 68 is 4

Answer:

a is D and b is C

Step-by-step explanation:

Slope is always with an x, b is always alone

Hey there!

Please remember that

Is y=4x-5 written in slope-intercept form (y=mx+b)? Sure! :)

Therefore, the slope, m, is 4, and the y-intercept, b, is -5.

Same with the second equation:

y=2/3-x

or

y=x-2/3

here, the y-intercept, b, is 2/3, and the slope, m, is -1.

Now, what's the equation of the line with a slope of 2 and a y-intercept of -7?

That's right, y=2x-7.

Hope everything is clear.
