Whats 30 times 30 plus 45 minus 456

Answers

Answer 1
30 times 30 plus 45 minus 456 is 489
Answer 2

Answer:

489 or -113

Step-by-step explanation:

Whats 30 times 30 plus 45 minus 456

rewrite in terms of numbers:

30 * 30 + 45 - 456

remember the order of operations and solve:

30 * 30 + 45 - 456

=900 + 45 -456

= 945 - 456

= 489

the answer could change depending on the placement of parenthesis, such as if the equation was:

30 * (30 + 45 -456)

solve with the order of operations:

30 * ( 30 + 45 - 456)

= 30 * (75 - 456)

= 30 *(-381)

= -11430

Find the midpoint of the line segment with end coordinates of: (−1,−6)and (4,5) Give coordinates as decimals where appropriate.

Answers

Answer: The coordinates of the midpoint (1.5, -0.5)

Step-by-step explanation:

For the x-coordinate, find the difference between -1 and 4. That's 5. Take half of 5 and add to -1. So -1+2.5= 1.5

For the y-coordinate, the difference between -6 and 5 is 11. Half of 11 is 5.5. Add -6 + 5.5= 0.5

Write an equation to find the number of students in Mr. Boggs' homeroom if the total number of students is 90.
Teacher: Number of students
Mr. Boggs b
Mr. Hamilton 15(b+2)
Ms. Simpson 15
Mrs. Walton 2b-9

Answers

Answer:

15(b+2) + 15 + 2b-9 +b = 90

Step-by-step explanation:

Essentially you add up all of the values and make it equal to 90, then solve for b

15(b+2) + 15 + 2b-9 +b = 90

15b + 30 + 15 + 2b - 9 + b = 90  

18b + 30 + 15 - 9 = 90

18b + 36 = 90

18b = 54

b=3

Find the midpoint of the line segment with end coordinates of: (−3,−1)and (−4,2) Give coordinates as decimals where appropriate.

Answers

Answer:

ANSWER

M=(−72,12).

Step-by-step explanation:

The midpoint for two points P=(x1,y1) and Q=(x2,y2) is

M=(x1+x22,y1+y22).

We have that x1=−3, y1=−1, x2=−4, y2=2.

So, M=(−3+(−4)2,−1+(2)2)=(−72,12)

Answer:

The answer is

( - 3.5 , 0.5)

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(−3,−1) and (−4,2)

The midpoint is

[tex]M = ( \frac{ - 3 - 4}{2} \: , \: \frac{ - 1 + 2}{2} ) \\ = ( - \frac{7}{2} \: , \: \frac{1}{2} )[/tex]

We have the final answer as

( - 3.5 , 0.5)

what is the value of x satisfies the equation 3( x +7 ) =18

Answers

Answer: -1

Step-by-step explanation:

3( x +7 ) =18

8Use distributive property

3x + 21 = 18

Substract 21 from both sides

3x = -3

Divide 3 by both sides

x = -1

Another way to solve:

3( x +7 ) =18

Divide 3 by both sides

x + 7 = 6

Substract 7 by both sides

x = -1

Answer:

x = -1

Step-by-step explanation:

In order to answer this question, all we have to do is simplify the equation:

3(x + 7) = 18

3x + 21 = 18

-21 -21

3x = -3

/3 /3

x = -1

You can even put this answer in the equation to check.

Answers

Answer:

Lower left.

Step-by-step explanation:

To determine if a graph is a function the "vertical line test is used.  If any point on a graph has one x value go to two y values it is not a function.  

Witht he four pictures, the two on the right use a horizontal line, so it doesn't tell at all, on the leftthe upper one is vertical but it doesn't show that one x value has two corresponding y values.  So it must be the lower left one.

The lower left picture has a line at x=1, and it passes through the line of the graph at two different y values, 4 and -4.  So this has two y values with one x value.

Answer:

I believe the graph with the line going through 1,0 (x,y) is correct because it doesnt pass the vertical line test

Step-by-step explanation:

7x7=49

8x8=64

9x9=81

10x10=100

11x11=121

12x12=144

Janine can build 12 models of equal dimension  (1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12).

What is a cube?

A three-dimensional object with six equal square faces is called a cube. The cube's six square faces all have the same dimensions.

A cube is become by joining six squares such that the angle between any two adjacent lines should be 90 degrees.

The surface area of the cube = 6 side².

The volume of the cube = side³.

Given that Janine can build up to 150 inches² area of cube.

Area of cube < 150

So,

13x13 = 169 > 150 And  12x12 = 144 < 150

So Janine can use up to 12 inches cube

Possible dimensions up to 12 inches are

(1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12).

Hence "Janine can build 12 models of equal dimension  (1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12)".
