Answer:
Need points sorry <3
Step-by-step explanation:
We first write the fractions in their decimal forms and find out the ratio.
2 1/4 is equivalent to 2.25, and 1 1/3 is equivalent to 1.33
Ratio will be 2.25 / 1.33 = 1.69 or 1.7 rounded off. Since it cannot be simplified further, then the ratio of mulch to gravel will be 1.7: 1
Quantity of mulch sold → 1.7/2.7 of 172 →0.629 ×172 = 108.2 pounds
Quantity of gravel sold will be 172 -108. 2 = 63 .8 pounds
Answer:
2:3, 2 to 3
Step-by-step explanation:
9 and 6 are both factors of three, so you have to reduce. 3 goes into 9 tree times, and 3 goes into 6 twice. Since it is circles to squares, the 2 comes first then 3.
Hope this helps!
Answer:
Two sides have a measure of 48 cm and the shortest side is 16 cm.
Step-by-step explanation:
this is an isosceles triangle
let x = length of shortest side
let 3x = length of other two sides
find x:
3x + 3x + x = 112
7x = 112
x = 16
3x = 48
Answer:
r = 33 , s = 18
Step-by-step explanation:
Rationalise the denominator by multiplying both numerator and denominator by the conjugate of the denominator.
The conjugate of 4 -
is 4 +
, then
← expand numerator/denominator using FOIL
= ![\frac{24+6\sqrt{3}+4\sqrt{27}+\sqrt{81} }{16+4\sqrt{3}-4\sqrt{3}-3 }](https://tex.z-dn.net/?f=%5Cfrac%7B24%2B6%5Csqrt%7B3%7D%2B4%5Csqrt%7B27%7D%2B%5Csqrt%7B81%7D%20%20%20%7D%7B16%2B4%5Csqrt%7B3%7D-4%5Csqrt%7B3%7D-3%20%20%7D)
