What is the minimum angle of rotation (in degrees) that will carry the six-sided star onto itself?
Answer:
The angle of rotation pf a six sided star, that will carry the six sided star onto itself is 60°
Step-by-step explanation:
The angle of rotation that will carry a six sided star onto itself is the angle between two adjacent lines of symmetry of the six sided star
Given that there are three lines of symmetry of the six sided star, and each line intersect with the next line at the center of the figure, the angle between two adjacent lines of symmetry = 360°/(2 × 3) = 60°
Therefore, the angle of rotation pf a six sided star, that will carry the six sided star onto itself = 60°.
The value of y directly proportional to the value of x. If y= 8 when x= 12, what is the value of y when x= -15?
The value of y directly proportional to the value of x. If y= 3 when x= 24, what is the value of y when x= -8?
Answer:
The value of y should be -10
Step-by-step explanation:
If x and y are proportional, then 8/12=y/-15
The fractions just show the y values over the x values
Cross multiply to get 12y= -120
y= -10
Jack's birthday is in 8 weeks. How many days is it until Jack's birthday? Complete the explanation on how you could use a number line to solve. Jack's birthday is in days. I would draw equal jumps of beginning at 0 on the number line. The jumps end at .
Answer:
Jack's birthday is in 56 days.
The jumps end at point 56 on the number line.
Step-by-step explanation:
Since one week has 7 days.
So, 8 week = 8 x 7 =56 days.
Hence, Jack's birthday is in 56 days.
On the number line, the current time is being represented by 0.
When I take one jump from 0, I will reach the point 1 on the number line, which corresponds to 1 day.
Again, in my 2nd jump from point 1 on the number line, the next point on the number line will be 2 which corresponds to 2 days.
This process repeats until I complete the 56 jumps to get point 56 on the number line, which corresponds to 56 days.
In this way, the number line can be used to solve.
Hence, the jumps end at point 56 on the number line.

· The senior class is planning an end of the year party to celebrate graduation. Their
total budget for food and drinks is $600. Each plate of food costs $5, and each drink
costs $1. Each person at the party gets one plate of food and one drink, with none
leftover. How many people went to the party?
Solve problem using systems of equations.
Answer:
100
Step-by-step explanation:
Because everyone had one plate and one drink, we can combine those individual prices.
5 + 1 = 6
Now we divide 600, the total cost, by 6, the cost for one person.
600 ÷ 6 = 100
So now we know that 100 people went to the party, as there was nothing left over.

The answer is A. 10x - 35
The perimeter of a rectangle is 48 centimeters. The relationship between the length, the width, and the perimeter of the rectangle can be described with the equation 2⋅length+2⋅width=48. Find the length, in centimeters, if the width is 10 centimeters
Answer:
The length of the rectangle is 14 cm
Step-by-step explanation:
Here, we want to find the length of the rectangle given the width
Mathematically, the perimeter of the rectangle can be calculated using the formula;
2( l + w)
from the question w = 10
and perimeter = 48
Thus;
2( l + 10) = 48
divide both sides by 2
l + 10 = 48/2
l + 10 = 24
l = 24 - 10
l = 14 cm

Step-by-step explanation:
find the slope and the y intercept 2x+y-2=0
Answer:
Slope: -2; Y-intercept: 2
Step-by-step explanation:
To find the slope, you can rewrite the equation into standard form:
2x+y-2=0
2x+y=2
y=2-2x
The slope is the coefficient of x, which is -2. The y-intercept is the other number, which is 2.
Step-by-step explanation:
gradient= ‐2
y‐ik intercept=2
explanation: rearrange the equation to make y your subject
from the equation , you already know that ‐2 is m (from the equation y=mx +c , whereby m is your gradient) which means ‐2 is your gradient.
from your equation you would also know that 2 is your y‐intercept. also from the equation y=mx+c is your UK intercept

Solve |4x +3| < 5
I’m stuck on this question
Answer:
x < 1/2
x > -2
Step-by-step explanation:
We know that 4x + 3 < 5 and 4x + 3 > -5
4x + 3 < 5
~Subtract 3 to both sides
4x < 2
~Divide 4 to both sides
x < 2/4 or x < 1/2
4x + 3 > -5
~Subtract 3 to both sides
4x > -8
~Divide 4 to both sides
x > -2

Answer:
∠COS = 30°
Step-by-step explanation:
∠BPO = 120° + x
∠COS = x
Alternate Interior/Exterior is congruent if two parallel lines are intersected by a transverse.
∠BPO = ∠COP
∠COP = 120° + x
∠COP + ∠COS = 180°
120° + x + x = 180°
120° + 2x = 180°
2x = 60°
x = 30°
