If you add 1.20 and 0.34, you get 1.54..
It depends which place you want it rounded to..
I am pretty sure your answer would be 1.50 then :)
Hope this helps you

Bert didn't finish 1/8 of the problems on a math test he made Mistakes on 1/6 of the problems the rest he answered correctly wha

Viefleur [7K]

Answer:

The fraction of the problems did he answer correctly is $(\frac{35}{48})$

Step-by-step explanation:

Here, let us assume the total number of problems in the test = p

Now, Bert did not finish 1/8 of the problems.

⇒The number of unfinished problems by Bert = $\frac{1}{8} \times p= \frac{p}{8}$

Also, the number of finished problems

= Total problems - Unfinished problems

$= p - \frac{p}{8} = \frac{7p}{8}$

Now, again 1/6 of the total finished problems had mistakes.

So, the number of problems with mistakes = $\frac{1}{6} \times \frac{7p}{8} = \frac{7p}{48}$

The total answers did correctly

= Total answers done - Problem with mistakes

$= \frac{7p}{8} - \frac{7p}{48} = \frac{(42 - 7)p}{48} = \frac{35}{48}p$

Hence, the fraction of the problems did he answer correctly is $(\frac{35}{48})$

A geometric sequence is shown below: a0, -11, 22, a1, 88, -176. A) What is the common ratio for this geometric sequence? -2 a2 B

xz_007 [3.2K]

Common ratio = 22/-11 = -2 also -76 / 88 = -2 confirms it.

B/ a0 = -11 / -2 = 5.5 and a1 = 88 / -2 = -44

So y=mx+b
the 'm' part means the slope which is found by 'rise/run'
a. y=2x+3 or y=2x+3
b. y=-1x+6
c. i'm not sure what this part means
d. this means 'what values will work for x and y in both equations at once so
y=-x+6 and y=2x+3
y=-x+6
add x to both sides
x+y=6
subtitute 'y=2x+3' for y in x+y=6
x+(2x+3)=6
collect like terms
3x+3=6
subtract 3 from both sides
3x=3
divide both sides by 3
x=1
sibtitue into x+y=6
1+y=6
subtract 1 from both sides
y=5

(1,5) is the solution (x,y)

Question 2
so amount of peanuts (x) =60%
ammount of almonds (y)=40%
y=2(1/3x) or y=2/3x
so there is a mixture that is8/10 almonds
for
a. i'm not sure about this one
b. so 60% of 5 pounds=3 pounds
40% of 5 pounds=2pounds
we need to find out how many pounds, times 8/10, = 2pounds

she will need 2.5 pounds of the pure peanuts and 2.5 pounds of the almond-peanut mixture
