Oscar rides his skateboard 5/8 mile in 1/4 hour. How fast, in miles does he ride his skateboard

Answers

Answer:

2.5 miles per hour

Step-by-step explanation:

[tex]\frac{1}{4}\times \frac{5}{8}[/tex]

Step 1: Apply the fraction rule: [tex]\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]

[tex]\frac{1}{4}\times \frac{5}{8}=\frac{1\times \:5}{4\times \:8}[/tex]

Step 2: Set up the fraction

[tex]\frac{5\times \:4}{8}[/tex]

Cancel the numbers: [tex]\frac{4}{8}=\frac{1}{2}[/tex][tex]=\frac{5}{2}[/tex]Convert to decimal[tex]\frac{5}{2} = 2.5[/tex]

Therefore, Oscar's speed is 2.5 miles per hour.

If PR is 4, WQ is 8, and QR is 5, SP = ___ units

Answers

Answer:

From the attached graphic, we can see:

(SP + PR) * PR = (WQ + QR) * QR

SP * PR + PR^2 = WQ * QR + QR^2

4 SP + 4*4 = 8 * 5 + 25

4 SP + 16 = 65

4 SP = 49

SP = 49 / 4

SP = 12.25

Can u Put 9x + 3y = -9in slope intercept form ?

Answers

Answer:

y = - 3x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

9x + 3y = - 9 ( subtract 9x from both sides )

3y = - 9x - 9 ( divide terms by 3 )

y = - 3x - 3 ← in slope- intercept form

Answers

Answer:

3 ft , 4 ft and 5 ft is a triangle.

Step-by-step explanation:

The first is not a triangle as 4 + 4 = 8 so triangle cant be drawn with these lengths.

Also third: 3 + 3 < 7 and last one 4 + 5 < 10 so neither are triangles.

What is the arc measure of \stackrel{\LARGE{\frown}}{AB}


AB





A, B, start superscript, \frown, end superscript on circle PPP in degrees?


^\circ





degrees


Answers

Answer:

72 degrees

Step-by-step explanation:

Find the diagram attached. We are to find the length of the arc

Measure of arcABC = rtheta

16π = 10 theta

theta  = 16*180/10

theta = 16 * 18

theta = 288degrees

central angle = 360 - 288 = arc AC

central angle = 72degrees

Hence the arc measure of AC is 72 degrees

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 90 pounds. The truck is transporting 50 large boxes and 65 small boxes. If the truck is carrying a total of 4950 pounds in boxes, how much does each type of box weigh?

Answers

Answer:

small = 30 pounds

large = 60 pounds

Step-by-step explanation:

two equations can be derived from the question

x + y = 90 eqn 1

50x + 65y = 4950 eqn 2

x = small box

y = big box

multiply equation 1 by 50

50x + 50y = 4500 eqn 3

subtract equation 3 from 2

15y = 450

y = 30

substitute for y in equation 1

y = 60

If the area of the rectangle shown is given by the expression 3x2 + 72 - 6and the width is (a + 3), which of the
following would represent the length? Remember: A = lw (Hint: Box method multiplication may be helpful here!)

Answers

Answer:

3x - 2.

Step-by-step explanation:

The length = area / width.

The area 3x^2 + 7x - 6 = (3x - 2 )(x + 3)

so the length =  (3x - 2 )(x + 3 ) / x + 3

= 3x - 2.

A triangle has one angle that measures 19 degrees, one angle that measures 118 degrees, and one angle that measures 43 degrees.

What kind of triangle is it?

A. right triangle

B. obtuse triangle

C. acute triangle

D. equilateral triangle

Answers

Answer:

B. obtuse triangle

Step-by-step explanation:

Obtuse triangles are triangles with one obtuse angle and two acute angles. Define obtuse angles as angles over 90 degrees and acute angles as angles less than 90 degrees.

In this triangle:

118 degrees - obtuse angle

19 degrees - acute angle

43 degrees - acute angle

Thus, this triangle is an obtuse triangle.

The answer is D

x = 3y
4x + 5y = 34

solve for x and y


Help help

Answers

Answer: y=2 and x=6

Step-by-step explanation:

x=3y

4x+5y=34

From equation ( 1) x=3y thus substituting in eqn(2)

4(3y)+5y=34

12y+5y=34

17y=34

y=34÷17=2

Thus y=2

Putting y=2 in eqn(1)

x=3y

x=3(2)

x=6

Nine students can make a poster in 10 hours how many students join them so that they can all together make this poster in six hours

Answers

Answer:

there is not enough information

Answer:

If 9 students make the poster in 10 hours
Then it would take 1 student 90 hours to make 1 poster
Therefore you do 90 hours/6hours to get 15
So you'd need 15 students to make the poster in 6 hours
Which means 6 more students would need to join them

6, 8, 11, 12, 2x – 8, 2x + 10, 35, 41, 42, 50
are in ascending order. If the median is 25,
find the value of x.
Ans: 12​

Answers

Answer:

12

Step-by-step explanation:

(2x-8+2x+10)/2 = 25

(4x+2) = 2×25

4x+2 = 50

4x = 50-2

4x = 48

x = 48/4

x = 12

Answer:

x = 16.5 as the median in this term is 2x-8

and 2x-8 = 25

25+8=2x

33=2x

x=[tex]\frac{33}{2}[/tex]

Determine the volume of the space in the tank that still needs to be filled with water if the water is ⅓ ft. Deep

Answers

Answer:

11 1/9 ft^3

Step-by-step explanation:

find the complete question in the attached image

volume of the tank = length x width x height

2 x 5 x 1 2/3

2 x 5 x 5/3 = 50/3 = 16 2/3 ft^3

If the tank is 1/3 filled with water, the volume that needs to be filled with water is 1 - 1/3 = 2/3

volume that needs to be filled with water = 2/3 x volume of the tank

2/3 x 50/3 = 11 1/9 ft^3

someone please help or i’ll be failing geometry this year

Answers

Step-by-step explanation:

I don't know what constructions you were taught.

a "similar" triangle is a triangle with exactly the same angles as the other triangle, but the lengths of all sides are stretched or shortened by the same scaling factor f.

by saying 1:2 she means the second triangle should have sides with twice the lengths of the first triangle (f=2).

and the extra challenge - same basic thing. she allows you to pick one of the two triangles as reference. and then you need to draw a third triangle (again with the same angles) with the side lengths extended by the scaling factor f of 4/3.

I would draw the triangles right on top of each other with the same starting corner (let's call it A) for all 3.

we would get the triangles ABC, AMN and AXY.

the points B and C would be then halfway on AM and AN.

and M and N would then a bit before X and Y on AX and AY.

the beauty is, you only need to construct 2 sides of every new triangle down to the new endpoints. the third side is automatically scaled correctly, and you only need to connect these new endpoints.

let's assume you draw a triangle (just very simple) ABC with all side lengths being 3. so, AB=3, AC=3, BC=3.

now you draw AMN by extending AB and AC to a side length of 6 (f=2) creating M and N, and you connect M and N.

and then you can create the third triangle AXY by extending AM and AN by a factor of 4/3 to side lengths of 8 (4/3 × 6 = 8) creating new end points X and Y. and you connect X and Y.

and that is it. all 3 triangles are similar (the same angles), and all sides of a triangle have the same length ratio to the sides of the other triangle(s).

Displace the block from the system's equilibrium position to a new vertical position. 4. Release the block from rest. 5. Use a meterstick to measure the vertical displacement of the center of mass of the block from the system's equilibrium position to its maximum vertical position above the equilibrium position. 6.
