Mathematics Question!
Mika estimated the sum of 189.27, 15.8, and 11.2 by rounding each number to the nearest whole.
What was Mika’s estimate and what is the actual sum of the numbers?
Enter your answers in the boxes
Mika estimated the sum to be blank. The actual sum is blank
PLEASE DON’T ANSWER IF YOU DON’T NO THE ANSWER!
Answer:
Mika's estimated the sum to be 216. The actual sum is 216.27
Step-by-step explanation:
Mika:
189.27 = 189
15.8 = 16
11.2 = 11
189 + 16 + 11 = 216
Actual:
189.27 + 15.8 + 11.2 = 216.27
helppppp! please show your work!
Answer:
90 - 37 will give a solid 53
Step-by-step explanation:
the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)
and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37
now we add angle degrees and sum and subtract one another,
90 - 37
can some one PLS help me with this problem it will be great x+5<-4

In each of the following cases detemin the slop and the y intercept of the line whose equation is given y=2x+5
2y=4x_5
3x+6y=8
x+y=(x_y)
Answer:
Step-by-step explanation:
y = mx +b
m- Slope ; b - y-intercept
1) y = 2x + 5
Slope = 2
y-intercept = 5
2) 2y = 4x - 5
Divide the equation by 2
[tex]\frac{2y}{2}=\frac{4x}{2}-\frac{5}{2}\\\\y = 2x - \frac{5}{2}[/tex]
Slope = 2
y-intercept = [tex]\frac{-5}{2}[/tex]
3) 3x + 6y = 8
6y = -3x + 8
[tex]\frac{6y}{6}=\frac{-3x}{6}+\frac{8}{6}\\\\ y = \frac{-1}{2}x+\frac{4}{3}\\\[/tex]
Slope = -1/2
y-intercept = 4/3
help plz- these were given to me and i was told i could only get help on two-

0, start text, space, m, end text, squared.
Answer:
When there is no width, the area is 0m²
Step-by-step explanation:
Expressing the area of a rectangle as a function of its width:
Area of a rectangle = Length * width
Since the area of rectangle is related to the width by the multiplication operatkr. We can conclude from the options given that ; if the value of width = 0 ; the the area of rectangular plot = 0
When x :
Area = Length * width
Area = Length * 0
Area = 0
Area = Length * 0
Aea = 0

someone help i found the slope already.
Answer:
s(x)
Step-by-step explanation:
s(x) is a linear function, so the average rate of change is its slope.
Its slope is 3.
You are correct.
To find the average rate of change of polynomial function t(x) from -2 to 2, find the values of t(x) at x = -2 and at x = 2.
average rate of change = [t(2) - t(-2)]/[2 - (-2)]
t(x) = 0.1(x^3 - x^2 + 2)
t(-2) = 0.1[(-2)^3 - (-2)^2 + 2)]
t(-2) = 0.1(-8 - 4 + 2)
t(-2) = -1
t(2) = 0.1[(2)^3 - (2)^2 + 2)]
t(2) = 0.1(8 - 4 + 2)
t(2) = 0.6
average rate of change = [t(2) - t(-2)]/[2 - (-2)]
average rate of change = [0.6 - (-1)]/4
average rate of change = 1.6/4
average rate of change = 0.4
average rate of change for s(x) = 3
average rate of change for s(x) = 0.4
Answer: s(x)

Write the equation in standard form for the circle that has a diameter with endpoints (- 1, 12) and (- 1, 8)
Answer:
The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]
Step-by-step explanation:
The distance from (-1, 12) to (-1, 8) = 4 = diameter of the circle. So, 2 = radius
The center of the circle is at (-1, 10)
The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]

Subtract -2x^2+4x-1−2x 2 +4x−1minus, 2, x, squared, plus, 4, x, minus, 1 from 6x^2+3x-96x 2 +3x−9
Answer:
-86x^2 -2x - 8
Step-by-step explanation:
The solution is:
6x²+2x²+3x-4x-9+1 becomes 8x²- x -8.
What is Subtraction?Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.
Here, we have,
Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).
To subtract -2x^2+4x-1 from 6x^2+3x-9,
that is
6x^2+3x-9 - (-2x^2+4x-1).
This can be written as
6x²+3x-9 - (-2x²+4x-1)
Now, opening the bracket, we will get
6x²+3x-9 +2x²-4x+1
Then, collecting like terms, we get
6x²+2x²+3x-4x-9+1
6x²+2x² = 8x²
3x-4x = -x
-9+1 = -8
∴6x²+2x²+3x-4x-9+1 becomes 8x²-x -8
The answer is 8x²-x -8.

help!! help!! help!! help!! help!! help!! help!! help!! help!! USING THE ELIMINATION METHOD SOLVE THESE PLEASEE HELPPPO!!!!!
Answer:
a = 15, b = -14
Step-by-step explanation:
From the question,
a/5 - b/2 = 10
Multiply all through by 10
(a/5)10 - (b/2)10 = 10×10
2a - 5b = 100...................... Equation 1
a - b = 29 ........................ Equation 2
Solving equation(1 ) and equation (2) simultaneously
using elimination method,
multiply equation (2) by 2.
2a - 2b = 58.................... Equation 3
Substract equation 3 from equation 1
2a - 2a -5b-(-2b) = 100-58
0 - 5b+2b = 42
-3b = 42
b = 42/-3
b = -14.
Substitute the value of b into equation 2
a - (-14) = 29
a +14 = 29
collect like terms
a = 29-14
a = 15.
Hence, a = 15, b =-14

Mark is installing a mosaic tile backsplash and the shape of the tiles are shaped like regular octagons. Each tile has a length from side to side of 6 in. Once Mark gets a few pieces on the wall, he realized that there is a gap that the tiles do not cover. What size tile must he get to fill the gaps?
Answer:
square with sides of 6 in
Step-by-step explanation:
Tessellation is the arrangement of shapes in repeated patterns without gaps or overlapping.
Tessellation is usually done with regular polygons. Only three regular shapes can tessellate, these are equilateral triangle, regular square and regular hexagon. For other polygon to tessellate, more than one shape must be used. A octagon can be used to make tessellations if it is used together with a square.
Mark uses tiles with shape of octagon of sides 6 in. To fill the gaps, Mark have to uses a square with sides of 6 in
