Answer:
y = 7.
Step-by-step explanation:
The work for this is in the attachment. Since WXY = ZOP, then sides OP and XY are congruent.
Therefore, you can use XY on the other side of the equal sign to figure out the variable.

which expression could be used to determine the product of -4 and 3 1/4
Answer:
B (-4)(3) + (-4)(1/4)
Step-by-step explanation:
We must find the product of -4 and 3 1/4, which is (-4)(3 1/4). We know that 3 1/4 = 3 + 1/4, so we substitute that to the expression we want.
(-4)(3 1/4) = (-4)(3 + 1/4)
Using the distributive property, we distribute the -4 to the 3 and the 1/4 and the expression becomes
(-4)(3 + 1/4) = (-4)(3) + (-4)(1/4)
I hope this helps! :)
does anyone know how to solve this
Step-by-step explanation:
7 + 2x + 3 = x + 10
2x - x = 10 - 7 - 3
x = 0
What?
I don't think this helps...
Answer:
x = 0.
Step-by-step explanation:
The distance between the point U and W are x + 10 and 2x + 3 + 7 so we can make the following equation:
x + 10 = 2x + 3 + 7
x + 10 = 2x + 10
Subtract 10 from both sides:
x = 2x
Subtract x from both sides:
0 = x
x = 0

Answer:
First image:
C, D, and E are true.
Second image:
30 tbsp
Step-by-step explanation:
1 cup = 8 ounces
A is false.
1 quart = 4 cups
7 qt = 28 cups
28 + 4 = 32
32 < 34
B is false.
1 gallon = 8 pints
4 gallons = 32 pints
31 < 32
C is true.
1 gallon = 4 quarts
5 gallons = 20 quarts
20 < 21
D is true.
1 quart = 2 pints
15 quarts = 30 pints
30 = 30
1 ounce = 2 tablespoons
15 ounces = y tablespoons

Answer:
(x, y) = (-7, 5)
Step-by-step explanation:
I find a graphing calculator to be useful for solving equations by graphing. The graph shows the solution to be ...
(x, y) = (-7, 5)
__
In these equations, the y-coefficients are the same, so we can eliminate y by subtracting the first equation from the second.
(4x -6y) -(-2x -6y) = (-58) -(-16)
6x = -42 . . . . . . . . . simplify
x = -7 . . . . . . . . divide by 6
Substituting into the first equation gives ...
-2(-7) -6y = -16
6y = 30 . . . . . . . . . . add 16+6y to both sides
y = 5 . . . . . . . . .divide by 6
The solution is (x, y) = (-7, 5).

If a quadratic equation is given to you in vertex form, what is the vertex?
If for example, you were given y = 2(x-3)^2 + 5, then the vertex is (3,5)
As another example, the equation y = 7(x+1)^2 + 10 has the vertex (-1,10)
The general vertex form is y = a(x-h)^2 + k with the vertex (h,k)
Answer:
(-h,k)
Step-by-step explanation:
vertex form:
y＝a(x-h)^2+k
switch sign of h and you get the x
keep sign of k and you get y
ex- 3(x-5)+7
vertex＝（5,7）

H
O
Р
Answer:
mEOP is 29°
Step-by-step explanation:
mHOP is 48° and mHOE is 19°, so to get the missing angle you subtract the smaller value from the total to get 29°
- 19-48=29
Which of the following is not true with respect to tests for the difference between two means when the population standard deviations are known? a. The samples must come from normally distributed populations or the sample sizes must be large enough to apply the central limit theorem. b. The samples must be randomly and independently selected. c. The test statistic for a hypothesis test has a t distribution. d. The margin of error for a confidence interval estimate is
Answer:
c. The test statistic for a hypothesis test has a t distribution
Explanation:
The test statistic when the standard deviation is known and population is normally distributed should not have a t-distribution. A t-distribution will be required for the test statistic for the hypothesis if standard deviation is unknown and population is also normally distributed. The other options are correct however.
ANSWER. Write the word or phrase that best completes each statement or answers the question. Solve the problem. 1) Two kinds of crated cargo, A and B, are to be shipped by truck. Each crate of cargo A is 50 cubic feet in volume and weighs 200 pounds, whereas each crate of cargo B is 10 cubic feet volume and weighs 360 pounds. The shipping company charges $75 per crate for cargo A and $100 per crate for cargo B. The
Answer:
To complete the problem statement it is needed:
1.- the volume and weight capacity of the truck, because these will become the constraints.
2.- In order to formulate the objective function we need to have an expression like this:
" How many of each type of crated cargo should the company shipped to maximize profit".
Solution:
z(max) = 175 $
x = 1
y = 1
Assuming a weight constraint 700 pounds and
volume constraint 150 ft³ we can formulate an integer linear programming problem ( I don´t know if with that constraints such formulation will be feasible, but that is another thing)
Step-by-step explanation:
crated cargo A (x) volume 50 ft³ weigh 200 pounds
crated cargo B (y) volume 10 ft³ weigh 360 pounds
Constraints: Volume 150 ft³
50*x + 10*y ≤ 150
Weight contraint: 700 pounds
200*x + 360*y ≤ 700
general constraints
x ≥ 0 y ≥ 0 both integers
Final formulation:
Objective function:
z = 75*x + 100*y to maximize
Subject to:
50*x + 10*y ≤ 150
200*x + 360*y ≤ 700
x ≥ 0 y ≥ 0 integers
After 4 iterations with the on-line solver the solution
z(max) = 175 $
x = 1
y = 1
Suppose that 60 batteries are shipped to an auto parts store, and that 5 of those are defective. A fleet manager then buys 6 of the batteries from the store. In how many ways can at least 4 defective batteries be included in the purchase
Answer:
In 8910 ways can at least 4 defective batteries be included in the purchase
Step-by-step explanation:
The order in which the batteries are there is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
4 defective:
4 defective from a set of 5 and 2 non-defective from a set of 60 - 5 = 55. So
[tex]C_{5,4}C_{60,2} = \frac{5!}{1!4!} \times \frac{60!}{2!58!} = 8850[/tex]
5 defective:
5 defective from a set of 5 and 1 non-defective from a set of 60 - 5 = 55. So
[tex]C_{5,5}C_{60,5} = \frac{5!}{0!5!} \times \frac{60!}{1!59!} = 60[/tex]
In how many ways can at least 4 defective batteries be included in the purchase?
[tex]T = 8850 + 60 = 8910[/tex]
In 8910 ways can at least 4 defective batteries be included in the purchase
Given vectors a = <9, 9> and b = <–4, 7>, find 3a − 2b.
Answer:
35i+13j
Step-by-step explanation:
Vector a = 9i+9j
Vector b = -4i+7j
We need to find the value of 3a-2b.
3a = 3(9i+9j) = 27i+27j
2b = 2(-4i+7j) = -8i+14j
3a-2b = 27i+27j-(-8i+14j)
= 27i+27j+8i-14j
= 35i+13j
Hence, the required vector is equal to 35i+13j.
The vertices of figure KLMN are K(−2, −1), L(−2, −3), M(−5, −3), and N(−5, −1). If figure KLMN is reflected across the line x = 2, find the coordinates of vertex Nˊ.
Answer:
N'(9, -1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation include translation, reflection, rotation and dilation.
Reflection is the flipping of an object over the line of reflection. If the point A(x, y) is reflected over the line x = a, the y coordinate would remain but the x coordinate will change.
The vertices of figure KLMN are K(−2, −1), L(−2, −3), M(−5, −3), and N(−5, −1). If figure KLMN is reflected across the line x = 2, the new points would be at:
K'(6, -1), L'(6, -3), M'(9, -3) and N'(9, -1)

Answer:
5196
Step-by-step explanation:
So it's 5040+(-156)
We have to find the absolute value
|-156|=156
5040+156=5196
Answer:
5196 m
Step-by-step explanation:
The sea is level = 0
If Punack Jaya, is 5040 m above sea level then it would be = + 5040 m
If Lake Assal is 156 m below sea level then it would be = - 156 m
The difference between the two elevations:
= 5040 - (-156)
= 5040 + 156 --> two negatives create a positive
= 5196 m

Answer:
C. 116°
Step-by-step explanation:
The angles created by the tangent and chord are each half of the measure of the circular arc they intercept. So, you can figure angle 1 two ways:
the supplement of half the arc whose measure is shown: 180°-(128°/2)=116°half the measure of the remaining arc of the circle: (360° -116°)/2=232°/2=116°The measure of angle 1 is 116°.

The length of a rectangle is 12 m.
Its width is 15 m.
Find the area and perimeter of this rectangle.
Answer:
for perimeter you add all sides. so Lenth x2 + width x2 is 24+30 which would equal 54
for area it's Lenth times width so 12 times 15 equals 156
