The wildflowers at a national park have been decreasing in numbers. There were 1200 wildflowers in the first year that the park

Year New flowers

1 1200

2 300

3 75

There were 1200 wildflowers in the first year that the park started tracking them. Since then, there have been one fourth as many new flowers each year

Initially there are 1200 flowers and start decreasing by $\frac{1}{4}$

So first term is 1200 and common ratio is $\frac{1}{4}$ .

Its a geometric sequence so summation becomes

i =1∑ ∞ 1200( $\frac{1}{4})^{i-1}$

Now we find the sum

We use sum formula

$Sum = \frac{a}{1-r}$

Where a is the first term , a= 1200

r is the common ratio , r= 1/4

$Sum = \frac{1200}{1-(\frac{1}{4})}$

$Sum = \frac{1200}{\frac{3}{4}}$

Sum = 1600 wildflowers

A bag contains blue marbles and red marbles, 107 in total. The number of blue marbles is 7 more than 4 times the number of red m

Ratling [72]

Answer: red is 13.36

Blue is 93.625

Step-by-step explanation:

Let the red marbles be y

Based on the question,red is 4times which means 4y

And blue is 7times greater than red which means 7(4y)

Blue + red=107

7(4y) + 4y=107

28y+4y=107

32y=107

Divide both sides by 32

Y=3.34

Red =4y

Red= 4(3.34)

Red =13.36

Blue= 7(4y)

Blue=7(4×3.34)

Blue= 93.625
