Step-by-step explanation:
a clock is circular in shape with diameter of 25 cm. find the length of the arc between the markings 12 and 5 rounded to the nearest tenth cm
Answer:
32.7 cm
Step-by-step explanation:
For central angle θ in radians, the arc length is given by ...
s = rθ
The angle between 12 and 5 is 5π/6 radians, and the radius is 25/2 cm, so the arc length is ...
s = (25/2 cm)(5π/6) = (125/12)π cm ≈ 32.7 cm
The arc length between the markings is about 32.7 cm.
What is the value of x in the proportion StartFraction 2 and one-fourth over x EndFraction = StartFraction 1 and one-half over 3 and three-fifths EndFraction?
Answer:
x = 10 4/5
Step-by-step explanation:
We want to find the value of x in the expression below;
2 1/4/x = 1 1/2/3 3/5
The best thing to do here is to turn all the mixed fractions to improper fractions. Thus, we have;
9/2/x = 3/2/18/5
= 9/2x = 3/2 * 5/18
9/2x = 15/36
9 * 36 = 15 * 2x
324 = 30x
x = 324/30 = 10 8/10 = 10 4/5
Answer:
The correct answer is C or 0.5 or 1/2.
Step-by-step explanation:
I know this because I checked it 5 times.

Can anyone help me please very urgent due tonight being graded need help 2.Joey gets an allowance of $17 per week. He wants to buy a new basketball that costs $43.67. When will Jose be able to buy the basketball if he has already saved $22.22, but also has to pay $13.45 each week for snacks and school supplies? make an equation or inequality and solve. Show your work
A local restaurant offers a deal if you purchase 3 medium pizzas you get 2 side dishes for free if you get a total of 8 side dishes how many pizzas did you buy use table to show your work
Without solving, determine whether the equation has one solution, no solution, or infinitely many solutions. 6x+6=6(x+1)
Answer:
Infinite Solutions
Step-by-step explanation:
6x+6=6(x+1)
6x+6=6x+6
If both sides of the equations are equal, it will ALWAYS be infinite solutions:)
Answer:
Infinite solutions.
Step-by-step explanation:
You have to distribute the 6 to the x and the 1. You'll then realize that both sides have 6x+6, and since 6x-6x=0 and 6-6=0, If you solve this your answer would be 0=0 this means the problem has an infinite number of solutions.

1) Find the value of X if m < EDG= 112 degrees
Answer:
x = 12
Step-by-step explanation:
From the question given above, the following data were obtained:
m < EDG = 112°
m < EDH = 6x – 9
m < HDG = 4x + 1
x =.?
Thus, we can obtain the value of x as shown below:
m < EDG = m < EDH + m < HDG
112 = 6x – 9 + 4x + 1
112 = 6x + 4x – 9 + 1
112 = 10x – 8
Collect like terms
112 + 8 = 10x
120 = 10x
Divide both side by 10
x = 120/10
x = 12
Therefore, the value of x is 12.
The expression (y^20) (y^-5)^2 is equivalent to y^n. What is the value of n? n = 27 n = 10 n = -200 n = 17
Answer:
n = 10
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Given
([tex]y^{20}[/tex] ) ([tex](y^{-5}) ^{2}[/tex]
= [tex]y^{20}[/tex] × [tex]y^{-10}[/tex]
= [tex]y^{(20-10)}[/tex]
= [tex]y^{10}[/tex] → in the form [tex]y^{n}[/tex] with n = 10
Answer:
10.

Find the missing dimensions. Use the scale factor 1 inch:12 feet. A plastic toy bird has a wingspan of 5 inches. What is the actual bird wingspan? USE NUMBERS ONLY.
Answer: 60 feets
Step-by-step explanation:
Given the question :
Find the missing dimensions. Use the scale factor 1 inch:12 feet. A plastic toy bird has a wingspan of 5 inches. What is the actual bird wingspan?
Using a scale factor of 1 inch : 12 feet
Wingspan of plastic toy bird = 5 inches
Calculate the actual bird wingspan
(1 inch / 12 feet) = (toy bird wingspan / actual bird wingspan)
( 1 inch / 12 feet) = (5 / actual bird wingspan)
Actual bird wingspan = 5 × 12
Actual bird wingspan = 60 feets
compare 0.8 and 7/10
Answer:
O.8 is greater than 7/10
Step-by-step explanation:
0.8 is in the tenths Place So you know that equals 80 ones Out of one hundred. So you have 80/100 if you divide 80 and 100 by ten it reduces to 8/10. You know that 8/10 is greater than 7/10. Hope this helped .

how do you describe a correlation
Answer:
Correlation is a statistical technique that is used to measure and describe a relationship between two variables. Usually the two variables are simply observed, not manipulated. The correlation requires two scores from the same individuals. These scores are normally identified as X and Y.

can someone please help me with these questions ( show work plz)
Answer:
3) Y = -1.5
Step-by-step explanation:
7=-2y+4
We move all terms to the left:
7-(-2y+4)=0
We get rid of parentheses
2y-4+7=0
We add all the numbers together, and all the variables
2y+3=0
We move all terms containing y to the left, all other terms to the right
2y=-3
y=-3/2
y=-1+1/2
