Answer:
10.34 cm.
Step-by-step explanation:
First we need to calculate the angle between the hour and minute hand
We see that there are 5 * 5-minute intervals between the 2 hands and the clock has 12 * 5-minute intervals, so:
This is 5/12 * 360 = 150 degrees,
So we apply the Cosine Rule to the triangle:
x^2 = 4.5^2 + 6.2^2 - 2*4.5*6.2cos150
= 107.014
x = √107.14 = 10.34.
Missing length is 10.3cm to 1.d.p
The clock is a circle divided into 12
360/12=30 degrees for each part
1) 7 to 8
2) 8 to 9
3) 9 to 10
4) 10 to 11
5) 11 to 12
5 parts
30 x 5 = 150 degrees
We've got an angle between 2 lengths - cosine rule comes to mind for me.
a = root 6.2^2 + 4.5^2 - 2x6.2 4.5 x cos 150
= 10.34476764
length is 10.3cm to 1.d.p
(the others are to 1.d.p too)
Hope this helps!
What lines are parallel?
A: y=3x-2 and y=1/3x-3
B: y=x and y=3
C: y=0 and y=3
Please explain the answer!!! Will give brainliest!!!
Answer:
C
Step-by-step explanation:
y=0 gives the straight horizontal line passing through (0,0)
y=3 also gives straight horizontal line passing through (0,3)
In order to find out which two lines are parallel, let's find the slope of each line first.
The slope of the line y=3x-2 is 3.
The slope of the line y=1/3x-3 is 1/3
The slope of the line y=x is 1
The slope of the line y=3 is 0
The slope of the line y=0 is 0
Now, if two lines have the same slope, they are parallel to each other.
So if a line's slope is 0, the line parallel to it has a slope of 0.
So the parallel lines here are ↓
y=0 and y=3

Tisha and her scout troop are heading to the Swing Time zipline park. They plan to purchase
the group package. With the package, the cost per person is $5 less than the normal cost for
an individual. There are 12 scouts in Tisha's troop. Her troop leader called ahead and found
that the total cost for the group will be $150. What is the normal cost for an individual?
Answer:
$17.5
Step-by-step explanation:
divide 150 by 12 to get 12.5. 12.5 is what they paid per-person with the discount. add 5 to get 17.5 and that is the on-discounted price
The normal cost for an individual is $17.50.
Let's denote the normal cost for an individual as "N."
According to the given information, with the group package, the cost per person is $5 less than the normal cost for an individual. So, the cost for each scout in Tisha's troop is "N - $5."
There are 12 scouts in Tisha's troop, so the total cost for the group is given as $150.
We can set up an equation based on the total cost:
Total Cost = Cost per Person × Number of People
$150 = (N - $5) × 12
Now, let's solve for the normal cost for an individual (N):
$150 = 12N - $60
12N = $150 + $60
12N = $210
N = $210 / 12
N = $17.50
So, the normal cost for an individual is $17.50.

find area of the shaded portion of the figure
Answer:
[tex]\sf C) \quad 57 \frac34 \:cm^2[/tex]
Step-by-step explanation:
To find the shaded area, subtract the area of the semicircle from the area of the rectangle.
Formulae
[tex]\textsf{Area of a rectangle}=\textsf{width} \times \textsf{length}[/tex]
[tex]\textsf{Area of a semicircle}=\dfrac12 \pi r^2 \quad \textsf{(where r is the radius)}[/tex]
[tex]\textsf{Diameter of a circle}=2r \quad \textsf{(where r is the radius)}[/tex]
Area of rectangle
Given dimensions of the rectangle:
width = 7 cmlength = 11 cmSubstituting these values into the formula:
[tex]\implies \textsf{Area}=\textsf{7} \times \textsf{11}=77\: \sf cm^2[/tex]
Area of semicircle
Diameter of semicircle = 11 - 2 - 2 = 7 cm
⇒ Radius (r) = 7 ÷ 2 = 3.5 cm
[tex]\textsf{let}\: \pi=\dfrac{22}{7}[/tex]
[tex]\implies \textsf{Area}=\dfrac12 \left(\dfrac{22}{7}\right) (3.5)^2=19.25\: \sf cm^2[/tex]
Area of shaded region
= area of rectangle - area of semicircle
= 77 - 19.25
= 57.75

Answer:
60kph
Step-by-step explanation:
Distance = Rate X Time
640 = r x 4+ (r+5) x 7
640 = 4r + 7r + 35
640=11r + 35
640 - 35 = 11r
605 = 11r
r = 605 / 11
r= 55 kph
r=55 =5 =60 kph is the speed of the train
To see if the answer is right: 55 x 4 + 60 x 7 = 220 + 420 = 640 km

The endpoints of a
diameter of a circle are (2,
4) and (-4, 7). What is the
standard form of the
equation
of this circle?
I know one of the answer is not c
Hurry i got like 30 mins left and a girl is tired
Answer:
2nd option
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
the centre is at the midpoint of the endpoints of the diameter.
The coordinates of the centre is the average of the coordinates of the endpoints.
centre = ( [tex]\frac{-4+2}{2}[/tex], [tex]\frac{7-1}{2}[/tex] ) = ([tex]\frac{-2}{2}[/tex] , [tex]\frac{6}{2}[/tex] ) = (- 1, 3 )
the radius is the distance from the centre to either of the endpoints
using the distance formula to calculate r
r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2[/tex]
with (x₁, y₁ ) = (- 1, 3 ) and (x₂, y₂ ) = (2, - 1 )
r = [tex]\sqrt{(2-(-1))^2+(-1-3)^2}[/tex]
= [tex]\sqrt{(2+1)^2+(-4)^2}[/tex]
= [tex]\sqrt{3^2+16}[/tex]
= [tex]\sqrt{9+16}[/tex]
= [tex]\sqrt{25}[/tex]
= 5
then equation of circle is
(x - (- 1) )² + (y - 3)² = 5² , that is
(x + 1)² + (y - 3)² = 25

Is 2.67034165508… rational or unrational?
Answer:
Unrational
Step-by-step explanation:
Step 1: Determine what is rational and unrational
"A rational number includes any whole number, fraction, or decimal that ends or repeats. An irrational number is any number that cannot be turned into a fraction, so any number that does not fit the definition of a rational number."
Step 2: Now determine what our number fits into
Since our decimal isn't a whole number, isn't a fraction, and it is a decimal that continues to either repeat or just continues. Therefore, our number would fit into the unrational category. If our number is just 2.67034165508 then it would be a rational number since it ends. However, since we have the ... at the end that means that it continues and therefore falls into the unrational category.
Answer: Unrational

Brady dilates an oblique prism by a scale factor of 2/3. Determine the scale factors for perimeter, area, and Volume. (Answer as a fraction)
Using proportions, it is found that:
The scale factor for the perimeter is of [tex]\frac{2}{3}[/tex].The scale factor for the area is of [tex]\frac{4}{9}[/tex].The scale factor for the volume is of [tex]\frac{8}{27}[/tex].What is a proportion?A proportion is a fraction of a total amount.
For the perimeter, as it is given in units, the scale factor is the same, hence it is of [tex]\frac{2}{3}[/tex].
For the area, as it is given in units squared, the scale factor is squared, hence:
[tex]\left(\frac{2}{3}\right)^2 = \frac{4}{9}[/tex]
For the volume, as it is given in cubic units, the scale factor is eleveted to the third power, hence:
[tex]\left(\frac{2}{3}\right)^3 = \frac{8}{27}[/tex]
