How to solve -3/9 + ( -2 9/10)
[tex] - 3 \sqrt{8 + ( - 2 \times \frac{9}{10} } [/tex]
9514 1404 393
Answer:
-3 7/30-7.46994Step-by-step explanation:
We understand this to be two separate problems.
-3/9 +(-2 9/10) = -(3/9 +2 9/10)
= -(10/30 +87/30) = -97/30 = -3 7/30
__
-3√(8 +(-2(9/10))) = -3√(8 -1.8) = -3√6.2 ≈ -7.46994

A calculator can help with these, especially if it is able to deal with rational numbers. (Many graphing calculators and some scientific calculators will do that more or less nicely. My favorite Android calculator app makes arithmetic with fractions and mixed numbers very easy.)

length of the ribbon is 120 M. what is the length of 7/15 of the ribbon?
Answer:
56 M
Step-by-step explanation:
Reduce fractions to their lowest terms equivalents
Multiply the numerators and denominators of the fractions separately
[tex]\frac{7}{15}[/tex] * 120 = convert to fraction
[tex]\frac{7}{15}[/tex] * [tex]\frac{120}{1}[/tex] = convert to fraction
[tex]\frac{7 * 120}{15}[/tex] = apply fraction rule [tex]\frac{a}{b}[/tex] * [tex]\frac{c}{d}[/tex] = [tex]\frac{a * c}{b * d}[/tex]
[tex]\frac{7 * 120}{15 *1}[/tex] = apply rule a * 1 = a 15 * 1 = 15
[tex]\frac{120}{15}[/tex] = 8 divide the numbers
7 * 8 = 56 multiply the numbers
Solve the following inequality. Use interval notation.
9514 1404 393
Answer:
(-∞, -1/3) U (3, ∞)
Step-by-step explanation:
The given inequality is equivalent to two inequalities (joined with OR).
-(3x -4) +3 ≥ 8
-3x +7 ≥ 8 . . . . . . eliminate parentheses
-3x ≥ 1 . . . . . . . subtract 7
x ≤ -1/3 . . . . . divide by 3
3x -4 +3 ≥ 8
3x ≥ 9 . . . . . add 1
x ≥ 3 . . . . . . divide by 3
Then the solution to the inequality is the union of these intervals:
x ∈ (-∞, -1/3) ∪ (3, ∞)

Need help!!! Got the first try wrong
Answer: f(x+3) = -5x -9
Step-by-step explanation: Start by substituting (x+3) for x. When you do this, you'll get the answer
f(x + 3) = -5 (x + 3) + 6
When you multiply out the (x + 3) by the -5, you'll get an answer of (-5x -15), which gives you the full equation
f(x + 3) = -5x -15 +6
Now, you just have to combine the like terms of -15 and +6, or, 6-15, to get -9.

What is the value of x?
Enter your answer, as a decimal, in the box.
ft
Answer:
67.5 ft.
Step-by-step explanation:
Length of MA = 71.5 - 22 = 49.5 ft.
Length of BP = 97.5 - x.
So we have the equation:
22 / 49.5 = (97.5- x) / x
Cross multiply:
22x = 49.5(97.5 - x)
22x = 4826.25 - 49.5x
22x + 49.5x = 4826.25
71.5x = 4826.25
x = 4826.25/71.5
x= 67.5 ft.
Answer: x=97.5

P, Q, V, and K are collinear with V between K and P, and Q between V and K. If VP = 14x + 4, PK = x + 630, VQ = 17x + 6, and KQ = 11x + 5, solve for VP.
9514 1404 393
Answer:
VP = 214
Step-by-step explanation:
The order of points on the line is KQVP. The whole is the sum of the parts, so we have ...
KQ +QV +VP = KP
(11x +5) +(17x +6) +(14x +4) = x +630
42x +15 = x +630 . . . . . . . . . . . . . . . . . collect terms
41x = 615 . . . . . . . . . . . subtract x+15
x = 15 . . . . . . . . . . divide by 41
Then the measure of VP is ...
VP = 14x +4 = 14·15 +4 = 210 +4
VP = 214

Answer:
heliocentric = sun is center
geocentric = earth is center
Answer:
Heliocentric Theory goes with 2.
Geocentric Theory goes with 1.
Step-by-step explanation:
The Heliocentric theory is the theory that the Sun is the center of the solar system. Hence, the prefix "helio" which means "relating to the sun"
The Geocentric theory is the theory that the earth is the center of the solar system. Hence, the prefix "geo" which means earth.
A good way to remember which is which is to remember the prefixes.

A circle has a Diameter of 8 what is the perimeter and area
Answer:
Area is 16 pi or about 50.27
Perimeter/circumference is 8 pi or about 25.13
Perimeter of a circle is basically the circumference. the formula of the circumference is 2 pi r. 2r = diameter
that means the circumference is 8pi or about 25.13
The formula for the area of a circle is pi r^2
The radius, or r is half the diameter. so 8/2 = 4 . The radius is 4
pi * 4^2
4^2 = 16
16 pi is the area or about 50.27

The graph shows the result of a matrix transformation, where the pre-image has dashed lines. Which matrix operation is represented in the graph?
The matrix operation needed to transform the original matrix (pre-image) is represented by option C. ( [tex]T' = \left[\begin{array}{cc}-1&0\\0&-1\end{array}\right]\cdot \left[\begin{array}{cccc}-5&-8&-5&-3\\-9&-7&-3&-6\end{array}\right][/tex]. )
The operation used to obtain the image in dash lines is a rotation around the origin, which is defined by following vectorial expression:
[tex]T' = R\cdot T[/tex] (1)
Where:
[tex]T[/tex] - Original matrix (pre-image).[tex]R[/tex] - Rotation matrix.[tex]T'[/tex] - Resulting matrix (image).Where the original matrix is defined by the following matrix:
[tex]T = \left[\begin{array}{cccc}x_{1}&x_{2}&...&x_{n}\\y_{1}&y_{2}&...&y_{n}\end{array}\right][/tex] (2)
And the rotation matrix is:
[tex]R = \left[\begin{array}{cc}\cos \theta&-\sin \theta\\\sin \theta&\cos \theta\end{array}\right][/tex] (3)
Where [tex]\theta[/tex] is the rotation angle, in sexagesimal degrees.
If we know that [tex]\theta = 180^{\circ}[/tex], [tex](x_{1}, y_{1}) = (-5, -9)[/tex], [tex](x_{2},y_{2}) = (-8,-7)[/tex], [tex](x_{3},y_{3}) = (-5, -3)[/tex] and [tex](x_{4}, y_{4}) = (-3, -6)[/tex], then the resulting matrix is represented by this entity:
[tex]T' = \left[\begin{array}{cc}-1&0\\0&-1\end{array}\right]\cdot \left[\begin{array}{cccc}-5&-8&-5&-3\\-9&-7&-3&-6\end{array}\right][/tex]
The matrix operation [tex]T' = \left[\begin{array}{cc}-1&0\\0&-1\end{array}\right]\cdot \left[\begin{array}{cccc}-5&-8&-5&-3\\-9&-7&-3&-6\end{array}\right][/tex] is represented in the graph.
