A triangle PQR is right angled at R, with PQ=80cm and R=60cm. find QR?
pythagorus theorem

Answers

Answer 1

Answer:

Solution given:

A triangle PQR is right angled at R, with hypotenuse{h}PQ=80cm

and

base[b]PR=60cm.

perpendicular [P]= QR

by using Pythagoras law

=+

80²=QR²+60²

QR²=80²-60²

QR=[tex]\sqrt{2800}[/tex]

QR=20[tex]\sqrt{7}[/tex]=52.9=53cm

QR=53cm.

Darnell ran 550 yards in 3 minutes. At this rate, how many yards can he run in 6 minutes?​

Answers

Answer:

Darnell can run 1100 yards in 6 minutes

Step-by-step explanation:

There are 2 ways you can solve this

Method 1: You would have to divide 550 by 3 which you would get about 183, (the exact answer is very long so I recommend using a calculator). Then you multiply that by 6 to get 1100.

Method 2: This one would probably be easier. Since 3 x 2 is 6 then you can multiply 550 x 2 to get 1100.

I hope this helps!

Answer:

1100 yards

Step-by-step explanation:

Write it as an equation

550/3 = x/6

Cross multiply :

550 * 6 = 3x

3300 = 3x

x = 1100

Step-by-step explanation:

Equation:

m<DGF = m<DGE + m<EGF

Given:

m<DGF = 12y - 5

m<DGE = 5y + 6

m<EGF = 24

Work:

m<DGF = m<DGE + m<EGF

12y - 5 = 5y + 6 + 24

12y - 5 = 5y + 30

12y - 5y = 30 + 5

Reflecting over the y axis does not change the Y value. It multiplies the x value by -1.

A playground has two sandboxes. Each sandbox is in the shape of a right prism. The first sandbox has a square base with a side length of 8 feet. What is the area, in square feet, of the base of the first sandbox? Show or explain how you got your answer. Help

Answers

Answer:

64 ft²

Step-by-step explanation:

A prism is a three dimensional shape with two identical shapes facing each other known as bases. A right prism is a three dimensional solid with a polygon as its base and vertical sides which are perpendicular to the base.

Given that the first sandbox is a right prism a square base, hence this is a square prism (that is a cube).

Since the side length of the square base is 8 ft, hence the area of the base of the first sandbox is:

Area of the base = length * length = 8 ft * 8 ft = 64 ft²

what is an equation in point slope form of the line that passes through (-5, -4) and has a slope of 3

Answers

Answer:

y + 4 = 3(x + 5)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 3 and (a, b) = (- 5, - 4) , then

y - (- 4) = 3(x - (- 5) ) , that is

y + 4 = 3(x + 5)

Hi there! The point-slope is shown in the picture.

Both x1 and y1 are the ordered pairs or coordinate points. Not to be confused with the x and y, they are just for to form an equation of a line.

As we know, m is defined as slope.

What we have now are:

the value of slope (m = 3)(x1, y1) = (-5,-4)Point-Slope equation

Substitute the value of the point and slope in the equation.

Of six Kokomuka (Hebe Elliptica) seedlings, four have survived the winter.



What percentage of the seedlings survived?

Answers

Answer:

66.7%

Step-by-step explanation:

The number of seedlings planted is 6, while the number of seedlings that survived the winter is 4. Therefore the percentage of seedlings that survived can be gotten using the formula:

Percentage of seedlings survived = (survived seedlings / total seedlings planted) * 100%

Therefore substituting values gives:

Percentage of seedlings survived = (4 / 6) * 100% = 66.7%

A circle of radius 1 is inside a circle of radius 5. The smaller circle is rotated clockwise
on the larger circle without slipping until it arrives back at its starting point P. How
many revolutions (turns) will the small circle make? Be careful. The answer is not 5.





Answers

9514 1404 393

Answer:

  4

Step-by-step explanation:

Consider the arcs PQ and P'Q. When turns are made without slipping, these have the same measure. The length of arc PQ is ...

  PQ = CP·θ

The length of arc P'Q is ...

  P'Q = O₂Q·(∠PO₂Q)

Segment O₂A is parallel to CP, so angle AO₂Q is θ. Then ∠PO₂Q = θ+α, where α is the angle by which P' has rotated counterclockwise from A.

We are given that ...

  CP = 5, O₂Q = 1

Using the above relations, we can write ...

  5θ = 1(θ+α)

  α = 4θ

That is, for every full turn θ = 2π, the smaller circle makes turns totalling 4(2π) = 8π, or 4 full turns.

The small circle makes 4 revolutions to arrive at its starting point.
