Subtract 510 from 375 because you need to find how many more points that he needs to get

If he needs at least 510 points and he has 375 points, then you would simply subtract. 510-375=135. Russell needs at least 135 points to get an A in Science.
Hope this helps!

Roisin is a price analyst for a food distributor. One week she put together bids for 680 cases, 507 cases, 830 cases, 391 cases,

sineoko [7]

Answer: The average number of cases per bid is 599.

Step-by-step explanation:

Given: One week she put together bids for 680 cases, 507 cases, 830 cases, 391 cases, and 587 cases.

Total cases = 680 + 507 + 830 + 391+587

= 2995

Number of bids = 5

Now, average number of cases per bid = $\dfrac{\text{Total cases }}{\text{Number of bids}}$

$=\dfrac{2995}{5}\\\\=599$

Hence, the average number of cases per bid is 599.

Identify a pattern in each list of numbers. Then use this pattern to find the next number.

dsp73

Answer:

-140

Step-by-step explanation:

a₀ = 3

a₁ = 3 - 13*1 = -10

a₂ = -10 + 13*2 = 16

a₃ = 16 - 13*4 = -36

a₄ = -36 + 13*8 = 68

a₅ = 68 - 13*16 = -140

* a₀=3 n is integers and n ≥ 1

aₙ = aₙ₋₁ + (-1)ⁿ * 13 * (2)ⁿ⁻¹

The sum of two consecutive even number's is 66. find the numbers.

Elena L [17]

Answer:

$32\ and\ 34.$

Step-by-step explanation:

Let x be the smaller number.

The next even number will be (x + 2).

$x+x+2=66$

$2x+2=66$

Subtract 2 from both sides:

$2x+2-2=66-2$

$2x=64$

Divide both sides by 2:

$\frac{2x}{2}=\frac{64}{2}$

$x=32$

The smaller number is 32.

Larger number $=32+2=34$

What is the sum of the two largest numbers in the list

Dmitriy789 [7]

Answer:

$\frac{25}{39}$

Step-by-step explanation:

The given numbers are

$\frac 13,~\frac 27,~\frac 3{10},~\frac 4{13},~\frac 5{17}$

We need to find the sum of the two largest numbers in the list.

The values of each number are

$\frac{1}{3}=0.33..$

$\frac{2}{7}\approx 0.286$

$\frac{3}{10}=0.3$

$\frac{4}{13}\approx 0.308$

$\frac{5}{17}\approx 0.294$

Using these we can say that

$\frac{2}{7}$

It means two largest numbers in the list are $\frac{4}{13}\text{ and } \frac{1}{3}$ .

The sum of these two number is

$Sum=\frac{4}{13}+\frac{1}{3}$

$Sum=\frac{4\cdot 3+1\cdot 13}{39}$

$Sum=\frac{25}{39}$

Therefore, the sum of the two largest numbers in the list is $\frac{25}{39}$ .
