What is -1/2 + (3/4 x 4/9)
Answer:
[tex]-\frac{1}{6}[/tex]
Step-by-step explanation:
[tex]\frac{3}{4} *\frac{4}{9} =\frac{1}{3}[/tex]
[tex]\frac{1}{3} -\frac{1}{2}=-\frac{1}{6}[/tex]
Answer:
-1/6
Step-by-step explanation:
Using the PEMDAS rule, we start with the equation in the parentheses (3/4 x 4/9). 3 X 4 is 12 and 4 X 9 is 36, so the answer is 12/36. You can simplify this to 1/3. -1/2 plus 1/3 can also be written as 1/3 - 1/2. Next you will want to set the denominators equal to each other. In this case, I'll set them both equal to 6.
3 x 2 is 6, and 1 x 2 is 2, turning 1/3 into 2/6.
2 x 3 is 6 and 1 x 3 is 3, turning 1/2 to 3/6.
2/6 - 3/6 equals -1/6
Bella has $540 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $353.59.
She buys 3 bicycle reflectors for $4.98 each and a pair of bike gloves for $38.63.
She plans to spend some or all of the money she has left to buy new biking outfits for $49.20 each.
Write and solve an inequality which can be used to determine x, the number of outfits Bella can purchase while staying within her budget.
Answer:
(540 - 353.59 - (3 x 4.98) - 38.63) / 49.2 = X
Bella can buy 2 outfits without breaking her budget.
Step-by-step explanation:
Since Bella has $ 540 to spend at a bicycle store for some new gear and biking outfits, and she buys a new bicycle for $ 353.59, 3 bicycle reflectors for $ 4.98 each and a pair of bike gloves for 38.63, and she plans to spend some or all of the money she has left to buy new biking outfits for $ 49.20 each, to determine the number of outfits Bella can purchase while staying within her budget, the following equation must be performed:
(540 - 353.59 - (3 x 4.98) - 38.63) / 49.2 = X
(186.41 - 14.94 - 38.63) / 49.2 = X
132.84 / 49.2 = X
2.7 = X
Therefore, Bella can buy 2 outfits without breaking her budget.

The dairy goats on a farm give 2 gallons of milk each day.
How much milk do they give in 5 days?
Answer:
[tex]\huge\boxed{\sf 10\ gallons\ of\ milk}[/tex]
Step-by-step explanation:
=> 2 gallons of milk each day.
This means
1 day = 2 gallon of milk
Multiply both sides by 5
5 (1 day) = 5 (2 gallons of milk)
5 days = 10 gallons of milk[tex]\rule[225]{225}{2}[/tex]

Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. When he starts his shift, the water level shows 8 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups?

Alan wants to brick a pathway to his garden.The length of the path is 10 1/4 each brick is 5/8 of a foot long how many bricks can he fit along the length of the path
Answer:
He can fit 16.4 bricks or 16 1/4 bricks or he can fit 16 full bricks
Step-by-step explanation:
10 = 40/4
40/4 + 1/4 = 41/4
41/4 × 2/2 = 82/8
82/8 ÷ 5/8 = 16 2/8
2/8 ÷ 2/2 = 1/4

. Let X and Y be random variables of possible percent returns (0%, 10%,
15%, and 20%) for stock A and, with the joint probability distribution given
in the Table below:
Joint Probability Distribution for Random Variables X and Y
Y Return
X Return 0 5 10 15
0 0.0625 0.0625 0.0625 0.0625
5 0.0625 0.0625 0.0625 0.0625
10 0.0625 0.0625 0.0625 0.0625
15 0.0625 0.0625 0.0625 0.0625
(a) Find the marginal probabilities.
(b) Determine if X and Y are independent.
(c) Find the means and variances of both X and Y.
(a) The marginal distribution of X is
Pr(X = x) = ∑ Pr(X = x, Y = y)
… = 0.0625 + 0.0625 + 0.0625 + 0.0625
… = 0.25
That is, the first equality follows from the law of total probability, with the sum taken over y from {0, 5, 10, 15}. Each probability Pr(X = x, Y = y) is given in the table to be 0.0625.
Similarly, the marginal distribution of Y is
Pr(Y = y) = 0.25
(b) Yes, they're independent because
Pr(X = x, Y = y) = 0.0625,
and
Pr(X = x) Pr(Y = y) = 0.25 • 0.25 = 0.0625.
(c) The mean of X is
E[X] = ∑ x Pr(X = x)
… = 0.25 ∑ x
… = 0.25 (0 + 5 + 10 + 15)
… = 7.5
and you would find the same mean for Y,
E[Y] = 7.5
The variance of X is
V[X] = E[X^2] - E[X]^2
… = (∑ x^2 Pr(X = x)) - 7.5^2
… = 0.25 (∑ x^2) - 56.25
… = 0.25 (0^2 + 5^2 + 10^2 + 15^2) - 56.25
… = 31.25
and similarly,
V[Y] = 31.25
(each sum is taken with x and y from {0, 5, 10, 15})

what is the equation of the line that is parallel to 3x-y=4 and goes through the point (3,2).
Answer:
Step-by-step explanation:
In parallel lines gradient are the same so first re-arrange the given equation.
1. Ax+By=C
2. The equation is given in standard format [tex]3x-y=4[/tex]
Solve for m.
1. [tex]3x-y=4[/tex]
2. [tex]\frac{3x}{3} =\frac{4}{3}+\frac{y}{3}[/tex]
3. [tex]x=\frac{4}{3}+\frac{y}{3}[/tex]
Find the value of b using the formula for the equation of line.
[tex]y=mx+b[/tex]
Substitute the value of m into the equation.
[tex]y=(\frac{4}{3}+\frac{y}{3}) . x+b[/tex]
Substitute the value of x into the equation
[tex]y=(\frac{4}{3}+\frac{y}{3}).(3)+b[/tex]
Substitute the value of y into the equation
[tex]2=(\frac{4}{3}+\frac{2}{3}).(3)+b[/tex]
Find B
[tex]b= -4[/tex]
Now we know the value of m and b. Substitute them into y=mx+b to find the equation of the line.
[tex]y=\frac{4}{3} x+\frac{1}{3} yx-4[/tex]

Answer:
Option B
Step-by-step explanation:
For the polygons to be similar, the dilation ratio must be uniform for all sides.
>> In option A, each side of the bigger hexagon is 8cm while each side of the smaller one is 5 cm. Thus, the dilation ratio is uniform at 8:5. Thus, they are similar polygons.
>> In option B, the longer side of the big rectangle is 12 inches and reduces to 10 inches. Which means a ratio of 6:5 whereas, the shorter side reduces from 7 to 6 which is a ratio 7:6. Since both ratios are different, then it means that both rectangles are not similar.
>> In option C, the hypotenuse of the big triangle is 15 m and reduces to 10 m in the small triangle. This gives a ratio of 3:2.
The perpendicular side of the big triangle is 9m which reduces to 6 m in the small one. This is a ratio of 3:2.
The horizontal side of the big triangle 12m which reduces to 8m in the small triangle. This is a ratio of 3:2.
Since all the ratios are same, then they are similar triangles.
>> In option D, each side of the bigger polygon is 7ft while each side of the smaller one is 4ft. Thus, the dilation ratio is uniform at 7:4. Thus, they are similar polygons.

An aircraft factory manufactures airplane engines. The unit cost C (the cost in dollars to make each airplane engine) depends on the number of engines made. If x engines are made, then the unit cost is given by the function C(x)=x2-180x+20,482. How many engines must be made to minimize the unit cost? Do not round your answer.
Answer:
90 engines must be made to minimize the unit cost.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a>0, the minimum value of the function will happen for [tex]x = x_v[/tex]
C(x)=x²-180x+20,482
This means that [tex]a = 1, b = -180, c = 20482[/tex]
How many engines must be made to minimize the unit cost?
x value of the vertex. So
[tex]x_{v} = -\frac{b}{2a} = -\frac{-180}{2(1)} = 90[/tex]
90 engines must be made to minimize the unit cost.

Answer here
-10

(-8, -7)
(-7,-8) -10-+
Answer:
(-7 1/2, -7 1/2)
Step-by-step explanation:
Midpoint is 1/2 the x difference and 1/2 the y difference.
The x distance is the absolute values (can't have a negative distance) of
(x2 - x1) / 2 and the y distance is (y2 - y1) / 2.
So
Dx = (-8 -(-7)) / 2 = -1 / 2 or 1 / 2 and
Dy = (-7 - (-8)) / 2 = 1 /2 or 1 / 2
pick the point with the largest -x or smallest +x value and add distance
x = -8 + 1/2 = -7 1/2
pick the point with the largest -y or smallest +y value and add distance
y = -8 + 1/2 = -7 1/2
so midpoint is (-7 1/2, -7 1/2)
