Answer:
34.93
Step-by-step explanation:
Ok, so using the formula for a trapezoid, you would get that Jim's garden's area is equal to 135.
Since each grass bag can cover 20m of the garden,
135/20=6.75
You would need seven bags because you can't buy 6.75 bags at a store.
Since each bag of grass seed is 4.99, 7*4.99 = 34.93.
I'm doing this in dollars, so I'm assuming that one pound is 100 cents or something like that.
Answer:
1/3 * (8 + 4)
Step-by-step explanation:
Expression which represents 1/3 tines the sum of 8 and 4
Expressing mathematically,
Sum of 8 and 4 is written as (8 + 4)
1/3 of the sum is expressed as ; 1/3 x (8 + 4)
Hence,
1/3 * (8 + 4)
1/3 * 12
= 4
Expression is 1/3 * (8 + 4)
Result = 4
Answer:
26
Step-by-step explanation:
Okay so first, let's write out an equation:
36.26/49 = x/100
Then, multiply both sides by 100 to get the x isolated.
x = 74
100-74 = 26
So the percent decrease is 26
Answer:
I'm going to assume that you meant y=3x-8 and y=-4
This means that you would substitute -4 into the spot of y which gives you -4=3x-8. Once solved you would receive x=4/3.
Hope I helped have a nice day :)
