Answer:
1/4x (8 x - 15)
Step-by-step explanation:
write the division as a fraction
1/2x + 3/2x (x - 5 ÷ 2)
factor out 1/2 from the expression.
1/2x(x + 3(x - 5 ÷ 2))
divide the numbers.
1/2x(x + 3(x - 2.5))
distribute 3 through the parentheses.
1/2x(x + 3x - 7.5)
collect like terms.
1/2x(4x - 7.5)
1/2x(4x - 15/2)
factor out 1/2 from the expression.
1/2 x 1/2 x (8 x - 15)
multiply the fractions
= 1/4 x (8x - 15)
or alternative form
= 0.25(8x - 15)
Answer:
4000 sqft
Step-by-step explanation:
you multiply 5*10 which equals 50 then 8*10 which equals 80 then to find area you multiply 50*80 which equals 4000 sqft
The number of nine-players team= 21 teams.
The number of ten-players team= 5 teams.
<u>Step-by-step explanation:</u>
<u>step 1:</u> The total players signed up for a volleyball league= 118 boys+121 girls= 239 players.
<u>step 2:</u> The coach first makes a 9 players team= 239-9= 230 members
In this stage, the number of 9 players-team is one.
<u>step 3:</u> The remaining 230 players cannot be divided equally into 9 players, since 230 is not divisible by 9.
<u>step 4:</u> Find the number within 230 that is divisible by 9 as a whole. Check for easy number (9*20= 180 is within 230)
Therefore, 230-180= 50 players are remaining.
In this stage, the number of 9 players-team= 1+20= 21 teams with 9-players.
The number of 10 players-team= 50 players/10= 5 teams with 10-players.
1. Need distance formula to find how long it is then cut it in half to find the radius....d= 10.....r= 5
Need midpoint formula to find the center....midpoint= (-1, -1)
(h,k) in the equation of a circle is the center, "r" is the radius. When you plug in the center, you have to put the opposite signs...so......
equation of a Circle = (x - h)^2 + (y - k)^2 = r^2 = (x + 1)^2 + (y + 1)^2= 25
2. A= pi(r^2)
200.96= 3.14(r^2)
64 = r^2
r = 8
Then to find the circumference, C= 2(pi)(r) = 2 (3.14) (8) = 50.24
For 3 and 4, is there a diagram?
A quilt design uses parallelogram-shaped pieces that have a base measure of 4 inches and a height of 6 inches. If 15 pieces are used in the quilt, what is the total area of the parallelogram-shaped pieces in the quilt?
1.225 in.
2.360 in.
3.(450 in.)
4.900 in.
<span> 15*4*6 = 360 sorry but I only have the answers for number 1 and 2
