Equivalent fractions
3/10 = 6/20
1/4 = 5/20
4/5 = 16/20
Step-by-step explanation:
For
3/10
We Multiply numerator and Denominator by 2
= 3×2/10 × 2
= 6/20
For 1/4
We Multiply numerator and Denominator by 5
= 1×5/4× 5
= 5/20
For 4/5
We Multiply numerator and Denominator by 4
= 4×4/5× 4
4/5 = 16/20

Answer:
31
Step-by-step explanation:
A straight line has the angle 180 and this one is split by line segment BO. The 180 is now split into 149+x=180, so subtract 149 from both sides to get x=31

Answer:
266pi
Step-by-step explanation:
SA = 2*pi*r^2 + 2pi*r*h
= 2pi*r(r+h)
r = 7 and h = 12
2*pi*7(7+12) = 14pi*19=266pi
Answer:
TSA = 2 pi r (r+h)

The variable y varies directly with x . If x=2 and y = −7, find y when x = −6.
Answer:
Step-by-step explanation:
X=2
Y=-7
Then if x is -6 u have to find what times 2 is -6 Which is -3.
so -7 x -3 is 21. Y is 21
Step-by-step explanation:
[tex] \frac{2}{ - 6} = \frac{ - 7}{y} \\ y = \frac{( - 6) \times (- 7)}{2} \\ y = \frac{42}{2} \\ \boxed{y = 21}[/tex]
21 is the right answer.can someone please answer this for me?

QUESTION 23
Tamara has $50 to spend on craft supplies. She spends $30
plus a 5% tax at the store. How much change should she
receive?
Answer:
the answer is $18.5
Step-by-step explanation:
30 + tax is $31.50
Answer:
$18.50
Step-by-step explanation:
Before Tax Price: $30
Sales Tax Rate: 5%
After Tax Price: $18.50
How can you find how much the sales tax is? Let's say you're buying a $100 item with a sales tax of 5%. Your math would be simply:
[cost of the item] x [percentage as a decimal] = [sales tax]
Step 1 : $30 x .05 (5%) = $1.50 Step 2 : $30 + $1.50 = $31.50Step 3 : $50 - $31.50 = $18.50Someone help plz!! I need some anyone who’s good with slope help?
Answer:
1/6
Step-by-step explanation:
Slope is calculated as rise over run. Rise is the change in the y-axis while run is the change in the x-axis.
The two coordinates are (-2, -3) and (4, -2).
From (-2, -3), if you go up 1 unit, you would be at (-2, -2). If you go to the right 6 units, you would be at (4, -2).
So, the slope is 1/6.
Hope that helps.
Hank put $10,000 in an account for 10 years. The account earned 2.5% interest. How much interest had been earned by the end of the 10 years?
Answer:
A = P ( 1+ i )^n
A = 10,000(1+0.025)^10
= 10,000(1.025)^10
= $12,800.84
Step-by-step explanation:
A = future amount
i = interest rate
n = number of years
P = Present value
i.e i = 2.5% , P = $10,000 and n = 10 years

At what values of x, does f(x) = 0?
A. 4
B. 0
C. 2
D. 4.2
E. -8
F. -1
Answer:
-1, 2, 4
Step-by-step explanation:
f(x) is the function's value at any given x. In other words, it's your function's y coordinate. You're looking for where the y coordinate is zero - so, in other words, the x intercepts. Luckily for you, all the x-intercepts here are clearly marked and they were kind enough to give you the coordinates.
lyn put 3 7/8 gas in her gas tank. If there are now 18 1/6 gallons in her tank, how many gallons did she start with?
Answer:
14.3 gallons
Step-by-step explanation:
18 1/6 gallons - 3 7/8 = 14.29
18 - 3 = 15
1/6 - 7/8 = 15 - 0.70833333333 = 14.2916666667
You need to be careful here if you use basic subtraction, simply as two minus would change to addition.

Answer:
trisect the median. The centroid is 1/3 its length from the side.
Step-by-step explanation:
The centroid divides each median into parts with a ratio of 2:1. If you trisect the median, the centroid will be 1 unit from the side and 2 units from the vertex.
Karen bought a 40-pound bag of dog food at the beginning of the week. Her dogs ate f pounds of dog food during the week. Which expression can be used to find the amount of dog food that is left? 40 + f 40 - f F - 40 40/f
Answer:
40 - f
Step-by-step explanation:
Total pounds of food bought= 40 pounds
Total pounds of food eaten by the dog = f pounds
Total pounds of dog food left = Total pounds of food bought - Total pounds of food eaten by the dog
= 40 - f
Expression that can be used to find the amount of dog food that is left = 40 - f

Step-by-step explanation:
PLEASE HELP. WILL MARK BRAINLIEST TO THE PERSON WITH THE BEST ANSWER. PLEASE SHOW FULL SOLUTIONS. As shown in the diagram, the lines through points P and Q, and through points R and S are parallel. A transversal intersects the parallel lines at the point P and S, respectively, such that ⦣QPS=(2k+89)° and ⦣PSR=(3k+61)°.
Find the measure of ⦣QPS and ⦣PSR in degrees. THANK YOU VERY MUCH AND GOD BLESS.....
9514 1404 393
Answer:
∠QPS = 101°
∠PSR = 79°
Step-by-step explanation:
The marked angles are called "same-side interior angles" or "consecutive interior angles". By either name, they are supplementary.
(2k +89) +(3k +61) = 180
5k +150 = 180 . . . . . . . . . collect terms
5k = 30 . . . . . . . . . subtract 150
k = 6 . . . . . . . divide by 5
Then the angles are ...
∠QPS = (2·6 +89)° = 101°
∠PSR = (3·6 +61)° = 79°
Answer:
∠QPS = 2 x 6 + 89 =101°
∠PSR = 3 x 6 + 61 =79°
Step-by-step explanation:
∠QPS and ∠PSR are consecutive interior angles, they are supplementary
(2k+89) + (3k+61) = 180
5k + 150 = 180
5k = 180-150 = 30
k = 6
∠QPS = 2 x 6 + 89 =101
∠PSR = 3 x 6 + 61 =79
