Ratio of peanuts to raisins is 2:3.

The raisin number was altered so now the peanuts have to be equally altered as well.

45/3 = 15

15(2) = 30

The new ratio is 30:45. There are 30 peanuts.

Answer:

30 peanuts

Step-by-step explanation:

2 peanuts : 3 raisins

? peanuts : 45 raisins

the above can also be written out like this \frac{2}{3}=\frac{?}{45}

now cause of the rules of math 2 times 45 is equal to 3 times ?

so you can do 2 times 45 divided by 3 to get ?  

\frac{2X45}{3}=30

? is 30

Hope this helps!

If B = 1 - 2s^2 – s and C = 3 + 5s², find an expression that equals 3B + C in<br> standard form.
Keith_Richards [23]

Answer: -s² - 3s + 6

Step-by-step explanation:

b = 1 - 2s² - s

c = 3 + 5s²

Substitute

3b + c

3 (1 - 2s² - s) + 3 + 5s²

3 - 6s² - 3s + 3 + 5s²

Put like terms together

-6s² + 5s² - 3s + 3 + 3

-s² - 3s + 6

Hope I helped!

A ship at position (1, 0) on a nautical chart (with north in the positive y direction) sights a rock at position (7, 5). What an
Romashka-Z-Leto [24]

Answer:

0.69473828 radians east of north.

Step-by-step explanation:

Interpreting the information given on a Cartesian plane, the position of the ship will be (1,0) and that of the rock will be (7,5). Connecting the point (1,0) and (7,5) with a line and dropping a perpendicular line from point (7,5) to the x-axis to intersect the x-axis at (7,0), will form a right-triangle with base length 6 units and a height of 5 units.

<u>Finding the base length from points (1,0) and (7,0)</u>

d=√(x₂-x₁)²+(y₂-y₁)²

d=√(7-1)²

d= √6²

d=6 units

<u>Finding the height from points (7,5) and (7,0)</u>

d=√(x₂-x₁)²+(y₂-y₁)²

d=√(7-7)² + (0-5)²

d=√-5²

d=√25

d=5 units

So you now have a right triangle with base length 6 units and height 5 units.

To get the bearing of rock from ship position you apply the formula for tangent of an angle

Tan Ф = length of opposite side/length of adjustment side

TanФ=5/6

Tan Ф =0.83333333333

Tan⁻¹ (0.83333333333) =0.69473828 radians east of north.
