In a rectangular coordinate system, what is the number of units in the distance from the origin to the point $(-15, 8)$? Enter your answer
distance of a point [tex](x,y)[/tex] from origin is $\sqrt{x^2+y^2}$
so distance is $\sqrt{(-15)^2+(8)^2}=\sqrt{225+64}=\sqrt{289}=17$
Answer:
Distance=17 units
Step-by-step explanation:
Coordinates of the origin: (0, 0)
Coordinates of the point in question: (-15, 8)
Distance formula for any two points [tex](x_1,y_1), (x_2,y_2)[/tex] on the plane:

HELP ME!!!!And I mark as BRAINLIEST✨✨make sure show proper working
Answer:
54 km/h
Step-by-step explanation:
From H to G:
Let the distance be x km.
Average speed = distance/time
60 = x/ 3
60*3 = x
x = 180 km
From G to F:
Let the distance be y km.
Average speed = distance/time
45 = y/2
45*2 = y
y = 90 km
From H to F:
Total distance = x + y = 180 + 90 = 270 km
Total time = 3 + 2 = 5 hours
Average speed from H to F
= Total distance/ total time
= 270/ 5
= 54 km/h

Alex has a block of wood that is in the shape of a prism with the dimensions shown. He cuts a 10-cm square hole through the center of the prism. What is the volume of the remaining solid?
Answer:
1,120
Step-by-step explanation:
Find the volume of the larger figure. This can be represented using the formula for volume.
V = lwh
V = 5*18*18
V = 1620
Now, find the volume of the cut out piece of the wood. We will subtract this from the larger block.
V = lwh
V = 5*10*10
V = 500
Subtract, and you will have your answer.
1620 - 500 = 1,120

how to solve 2x(x+3)=2x^2+15
Answer: x = 5/2 = 2.5
Step-by-step explanation:
Given expression
2x (x + 3) = 2x² + 15
Expand parentheses and apply the distributive property
2x · x + 2x · 3 = 2x² + 15
2x² + 6x = 2x² + 15
Subtract 2x² on both sides
2x² + 6x - 2x² = 2x² + 15 - 2x²
6x = 15
Divide 6 on both sides
6x / 6 = 15 / 6
x = 15/6
[tex]\boxed{x=\frac{5}{2} }[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Step-by-step explanation:
2x^2 + 6x = 2x^2 + 15
2x^2-2x^2+6x=15
6x = 15
x= 5/2 when simplified

A club has 16 members, included Mary and Peter. If two representative are
randomly selected from those members, find the probability that
(d) Mary or Peter is chosen.
Answer:
12.5 percent; 2/16; 1/8
Step-by-step explanation:
Peter and Mary make up 2 of the clubs members, so the probability that they are chosen is 2/16. This simplifies to 1/8, and in decimal form is .125. Therefore, the percentage form of the probability they are chosen is 12.5 percent.
The image below shows two dilated figures with lines IJ and JK drawn. If the smaller figure was dilated by a scale factor of 2, what relationship do lines IJ and KL have?
Answer:
IJ = 2*KL
Step-by-step explanation:
Given that the smaller figure was dilated to create the bigger figure with a scale factor of 2, it therefore means, the dimensions of the smaller figure was increased by times 2 of its dimensions to create the bigger figure.
Thus, the relationship that would exist between line IJ and KL, is that IJ is twice the size of KL.
The relationship is: IJ = 2*KL

Betsy's high school is putting on a production of a play as a fundraiser for the school's music programs. A local bank has agreed to allow the school to use a line of credit from which they can withdraw money to pay for the play. Then, any deposits they make at the bank will be applied to the negative balance of the credit account. The play cost $3,200.00 to produce, and they intend to sell tickets for $10 each. After the play, Betsy will take the ticket proceeds and deposit them with the bank. If 1,007 people attend the play's opening night, what will the balance of the bank account be?
Answer:
Hey there!
If 1007 people attend, they will make a profit of 10070 dollars.
The play costed 3200 dollars to produce, so we have -3200+10070=7500 dollars as the final balance of the bank account.

Answer:
a=53
Step-by-step explanation:
[tex] \sin(45) = \frac{a}{53 \sqrt{2} } \\ \frac{ \sqrt{2} }{2} = \frac{a}{53 \sqrt{2} } \\ a = 53[/tex]
I hope I helped you^_^
Answer:
a = 53
Step-by-step explanation:
This is a 45- 45- 90 triangle with sides in the ratio x : x : x[tex]\sqrt{2}[/tex]
x are the legs and x[tex]\sqrt{2}[/tex] the hypotenuse
Here x[tex]\sqrt{2}[/tex] = 53[tex]\sqrt{2}[/tex] , then x = 53
That is the leg a = 53
A ball is thrown vertically upward from the ground with an initial velocity of 111 ft/sec. Use the quadratic function h(t) = −16t2 + 111t + 0 to find how long it will take for the ball to reach its maximum height (in seconds), and then find the maximum height (in feet). (Round your answers to the nearest tenth.)
Answer:
t=3.5 seconds
Step-by-step explanation:
Given
h(t) = −16t^2 + 111t + 0
h'(t)= -32t + 111
Maximum height occurs when h(t) = 0 and the ball begins to fall
h(t)= -32t + 111=0
-32t + 111=0
-32t=-111
Divide both sides by -32
t=3.46872
Approximately, t=3.5 seconds
Recall,
Maximum height occurs when h(t) = 0
h(t)= -32t + 111=0
= -32(3.46872)+111
= -110.99904+111
= 0.00096 ft

Answer:
120 $12 tickets and 180 $15 tickets
Step-by-step explanation:
Given the 2 equations
12x + 15y = 4140 → (1)
x + y = 300 ( subtract y from both sides )
x = 300 - y → (2)
Substitute x = 300 - y into (1)
12(300 - y) + 15y = 4140 ← distribute and simplify left side
3600 - 12y + 15y = 4140
3600 + 3y = 4140 ( subtract 3600 from both sides )
3y = 540 ( divide both sides by 3 )
y = 180
Substitute y = 180 into (2)
x = 300 - 180 = 120
Number of $12 tickets : 120 ; Number of $15 tickets : 180

Since the discriminant is negative, we will have 2 complex solutions
Answer:
2 complex solutions
Step-by-step explanation:
Given the standard form quadratic ...
ax^2 +bx +c
The expression b^2-4ac is called the "discriminant." Its value can be used to predict the type of solutions. Here, we have ...
a=2, b=4, c=4
so the discriminant is ...
d = b^2 -4ac = 4^2 -4(2)(4) = -16
Because the discriminant is negative, we can predict there are 2 complex solutions.

In the figure, ABC and DEF are similar. What's the scale factor from ABC to DEF?
(pls show how you got the answer)
Answer:
3
Step-by-step explanation:
The scale factor of ABC to DEF is the number you need to multiply a corresponding side of ABC to get one of DBC. We are given the two triangles are similar, so we can say that sides AB and DE are proportional. We are looking for the number we need to multiply AB by to get DE. From this relation, we can get the equation:
AB * x = DE
where x is our scale factor. We can substitute in the values of AB and DE, and solve for x:
5x = 15
x = 3
Therefore, the scale factor is three. This means that you can multiply any side of ABC by 3 to get a side of DEF.

Given that a quadrilateral PQRS is a parallelogram, PQ and RS are opposite sides, PQ = 7x + 16, RS = 5x +28, and QR = 67 which of the following statements are correct? More than one answer may be correct.
Answer:
PQ = 58
Perimeter = 250
Opposite sides are congruent
Step-by-step explanation:
PQ = 58:
Because PQRS is a parallelogram, PQ equals RS.
1. Set up the equation and solve
7x + 16 = 5x + 28
2x = 12
x = 6
2. Plug in x into PQ
7(6) + 16 = 58
Perimeter = 250:
PQ = RS and QR = SP
1. Add the sides
58 + 58 + 67 + 67 = 250
Opposite sides are congruent:

Type the correct answer in the box. Use numerals instead of words. The height of a baseball, in feet, is represented by this expression, where t is time in seconds. -16t squared+64t+3 The height of the baseball after 3.5 seconds is BLANK feet.
Answer:
31 Feets
Step-by-step explanation:
Given the expression for the height of a baseball:
Height(t) = -16t^2 +64t +3
Height in Feets ; time (t) in seconds
Height of baseball after 3.5 seconds :
Height(3.5) = -16(3.5)^2 + 64(3.5) + 3
Height = - 16(12.25) + 64(3.5) + 3
Height = - 196 + 224 + 3
Height = 31 Feets
Height after 3.5 seconds = 31 feets

I assume your question should be rephrased as "Josh has a bucket 30 inches deep..."
Josh is correct in estimating that it will take him under an hour to fill the entire bucket with water.
Given:
The bucket is 30 inches deepIt takes Josh 5 minutes to fill the bucket with 3 inches of waterTo find: If Josh is correct in estimating that it will take him under an hour to fill the entire bucket with water
It is given that, to fill the bucket with 3 inches of water, it takes Josh 5 minutes.
Using Unitary method, we can say that, to fill the bucket with 1 inch of water, it takes Josh [tex]\frac{5}{3}[/tex] minutes.
Then, to fill the bucket with 30 inches of water, it takes Josh [tex]\frac{5}{3} \times 30[/tex] minutes.
Solving, we can say that it takes Josh 50 minutes to fill the bucket with 30 inches of water.
Since the bucket is 30 inches deep, we can say that it takes Josh, 50 minutes to fill the entire bucket, which is just under an hour.
So, Josh is correct in assuming that it will take him under an hour to fill the entire bucket with water.
