A circular mirror measures 24 cm in diameter.
The cake is cut in half. Work out the perimeter of half of the mirror.
Answers
Answer:
The perimeter or circumference of a half mirror = 37.68 cm
Step-by-step explanation:
The diameter of circular measure = 24 cmWe know that the perimeter of a circular shape is called the 'circumference', with the formula
Circumference of a circle = C = 2πrWhen the mirror is cut into half, the diameter gets half as well.
Thus, the diameter of a half mirror = 24/2 = 12 cmWe know that radius = r = diameter / 2 = 12/2 = 6 cm
Thus, the perimeter of half of the mirror = C = 2πr
= 2(3.14)6
= 37.68 cm
Therefore, the perimeter or circumference of a half mirror = 37.68 cm

Annabelle went to the grocery store and bought bottles of soda and bottles of juice.
Each bottle of soda has 30 grams of sugar and each bottle of juice has 1o grams of
sugar. Annabelle purchased 3 times as many bottles of juice as bottles of soda and
they all collectively contain 120 grams of sugar. Graphically solve a system of
equations in order to determine the number of bottles of soda purchased, T, and the
number of bottles of juice purchased, y.
Answers
Answer:
120 = 3y + t
Step-by-step explanation:
120 = 3y + t because you purchase 3 times as many y then t. Overall, your answer should end up as 120 by using an equation like this.

(–2, 0)
(–1.5, 0)
(–6, 9)
(2, –3)
(3, –9)
(–4, 4)
Answers
Answer & Step-by-step explanation:
First write the line equation.
y=mx+b is the format where m=slope, b= y intercept
y=-2x-3
plug each x in to see if they match the point
y= -2(-2) -3 = -4 - 3 = -7 ; the point is (-2,0) so NO
y= -2(-1.5) -3= 3-3 = 0; point is (-1.5, 0) so YES it matches
y= -2(-6) -3 = 12-3 = 0; point matches so YES
y= -2(2) -3 = -4-3 = -7; point is (2, -3) so NO
y = -2(3) -3 = -6-3= -9; point matches so YES
y= -2(-4)-3 = 8-3 = 5; point is (-4, 4) so NO
(-1.5, 0) & (-6, 9) & (3, -9)

The highest point in the mountains of Seattle is 5,833 meters above sea level. The lowest point in the valley is 57 meters below sea level. What is the difference between the highest and lowest point?
Answers
Answer: 5890 meters
Step-by-step explanation:
Given: The highest point in the mountains of Seattle is 5,833 meters above sea level.
The lowest point in the valley is 57 meters below sea level.
in integers it is represented by -57 meters. [we use negative integer to represents "below"]
Difference between the highest and lowest point = Highest point - lowest point
= 5,833 meters -(-57) meters
= (5833 + 57) meters [a-(-b)= a+b]
= 5890 meters
Hence, the required difference = 5890 meters

Adam has 10 blocks numbered 1 through 10. Which describes the probability of randomly choosing a block that has an even number?
Answers
Answer:
[tex]\dfrac{1}{2}[/tex]
Step-by-step explanation:
Given that:
10 number of blocks which have numbers from 1 through 10.
To find:
Probability of randomly choosing a block that has an even number.
Solution:
The given set of numbers is: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
There are a total of 5 Even numbers are {2, 4, 6, 8, 10}.
And There are a total of 5 Odd number are {1, 3, 5, 7, 9}.
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, Event E is randomly choosing an even number.
Number of favorable cases = 5
Total number of cases = 10
Therefore, the required probability is:
[tex]P(E) = \dfrac{5}{10}\\\Rightarrow P(E) = \dfrac{1}{2}[/tex]

write an equation in slope-intercepts form for the line that passes through (5, -4) and is perpendicular to the line described by 2x-10y=0
EXPLAIN what you did in each step to arrive at your answer plz
Answers
Answer: [tex]y=-5x+21[/tex]
Step-by-step explanation:
In slope intercept form : y=mx+c , m= slope , c= y-intercept.
Let [tex]L_1[/tex] be the line passing through (5, -4) and perpendicular to [tex]L_2: 2x-10y=0[/tex].
Rewrite [tex]L_2[/tex] in slope-intercept form
[tex]10y=2x\Rightarrow\ y=0.2x+0[/tex]
Here, Slope of [tex]L_2[/tex] = m = 0.2
Let n be slope of [tex]L_1[/tex] .
Then [tex]m\times n=-1[/tex] [Product of slopes of perpendicular lines is -1.]
[tex]\Rightarrow\ n=\dfrac{-1}{m}=\dfrac{-1}{0.2}\\\\\Rightarrow\ n=-5[/tex]
Equation of a line that passes through (a,b) and have slope 'm' is given by :-
[tex](y-b)=m(x-a)[/tex]
So, Equation of [tex]L_1[/tex] :
[tex](y-(-4))=-5(x-5)\\\\\Rightarrow\ (y+4)=-5x+25\\\\\Rightarrow\ y=-5x+21[/tex]

What is the x-value in the solution to this system of linear equations?
2x − y = 11
x + 3y = −5
−3
−1
2
4
Answers
Answer:
(7, -3)
Step-by-step explanation:
Solve the system of linear equations
2x − y = 11
x + 3y = −5
by elimination by addition and subtraction. Multiply the second equation by -2, obtaining
2x - y = 11
-2x - 6y = 10
------------------
-7y = 21, which yields y = -3
Knowing that y = -3, we can now find the value of x. Let's use the first equation for this purpose. Substituting -3 for y, we get:
2x - (-3) = 11, or
2x = 11 + 3, or 2x = 14. Thus, x = 7.
The solution is (7, -3).

-3

Answer:
2x = y
Step-by-step explanation:
As you can see in the table, y = 2x, this is proven by the fact that if you divide any value in the y of the table by 2 you will get its corresponding x value, proving that 2x = y is the function that is used to represent this table's value.
Answer:
2x = y
Step-by-step explanation:
If x = 10
2x = y
2 * 10 = y
20 = y
