Answer:

23

Solving steps

We know x= -10-15y, so we can subtract it to the equation above

x = -10-15y

2x+5y=35

2(-10-15y) + 5y = 35

(Refer to the 1st image to solve for y)

Y = -11/5

We now know y= -11/5, so we can subtract it to the equation for x.

Y = -11/5

x = -10-15y

x = -10-15(-11/5)

(Refer to the 2nd and 3rd image to solve for x) (Make sure to look at both images first before writing something down)

x = 33 - 10

x = 23

Hopefully, everything was clear and concise. Please comment if you have any questions.

Answer:

3?

Step-by-step explanation:

First I added 20 dollars to 2.50 and I got 22.50 than  I divided 67.50 / 22.50 which gave me 3, so I guess the answer is 3. Hope this helped!

Answer:

The area of the shaded portion is 123 cm^2

Step-by-step explanation:

Here, we want to find the area of the shaded portion

To find this, we subtract the area of the smaller inner rectangle from that of the outside bigger one

Mathematically, the area of a rectangle at any point in time is length * width

For the bigger one, we have;16 * 9 = 144 cm^2

For the smaller inner one, we have ;3 * 7 = 21 cm^2

The area of the shaded portion which is the difference is;

144-21 = 123 cm^2

Answer: y= [tex]\frac{-3}{1}[/tex]x-4

Step-by-step explanation:

y=mx+b

y intercept (the y intercept is where the line intercepts the y axis) = -4

y= [tex]\frac{-3}{1}[/tex]x-4

Answer:

m is equal to -1 ± 2√3, which is approximately equal to 2.46 and -4.46

Step-by-step explanation:

-4m² + 2m - 11 = -5m²

m² + 2m - 11 = 0

m² + 2m + 1 = 12

(m + 1)² = 12

m + 1 = ± √12

m = -1 ± 2√3

Step-by-step explanation:

Answer:

The surface area is 286.5in.

Step-by-step explanation:

7.5 * 11.5 = 86.25 * 2 = 172.5in for two big rectangles

7.5 * 3 = 22.5 for little rectangle

11.5 * 3 = 34.5 * 2 = 69 for two medioum rectangles

7.5 * 3 = 22.5 for the smallest rectangle

22.5 + 69 + 22.5 + 172.5 = 286.5 in SA

This problem can take a while if you cannot observer the answer quickly.

First of all we can see that 32=2*2*2*2*2=2^5

243, if you don't know its actually is 3^5

Now we can see that this turns into...

- 2^5/3^5

since the 5th power doesn't change the sign of the original number, we can put the negative in the ( ), if you don't know what I mean look below

(-3)^2=9 Positive

(-3)^3=-27 Negative since its to the odd power it keeps the sign.

This problem can be simplified to.

(-2/3)^5

And this is the answer :D

If you have any questions just put them in the comments.

Answer: D

Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

Answer:

4329 softballs

Step-by-step explanation:

To find the number of softballs that will fit into the container, we first find the volume of the softball. Since it is a sphere, its volume V = 4πr³/3 where r = radius = d/2 where d = diameter of softball.

So, V = 4π(d/2)³/3 = πd³/6

Since d = 8.3 in,

V =  πd³/6 =  π(8.3 in)³/6 = π × 571.787 in³/6 = 299.39 in³

The volume of the box, V' = 15 × 10 × 5 ft³ = 750 ft³ = 750 × (12 in)³ = 750 × 1,728 in³ = 1,296,000

So, for n softball to fit, its volume must equal the volume of the storage unit.

The volume of n softballs is nV.

For the softballs to fit, V' = nV

n = V'/V

= 1,296,000 in³/299.39 in³

= 4328.8 softballs

≅ 4329 softballs since we cannot have a decimal number of softballs.

Answer:

65.97m³

Step-by-step explanation:

This is a right circular cone, so we will be using V = (1/3)(π)(r²)h

r = radius = 3m

h = height = 7m

V = (1/3)(π)(3m²)(7m) = 65.97m³

Answer:B

y=13cos(1/13x)+13

Step-by-step explanation:

The cosine equation to model the height of the red spot over a distance you ride is y = 13 cos (x/13) + 13. Then the correct option is B.

It is a function that repeats itself in a particular time interval.

You ride through some wet paint on your bike, creating a red spot on the tire.

Write a cosine equation to model the height of the red spot over the distance you ride.

Your bike tire has a radius (r) of 13 inches.

The period is the circumference of the tire (2πr).

The cosine equation is given as

y = A cos (Bx + C) + D

Where

A = the amplitude

B = time period

C = phase difference

D = shifting of central line

Then we have the diagram

A = 13

B = 1/13

C = 0

D = 13

Then the equation will be

[tex]\rm y = 13 \cos (\dfrac{1}{13}x - 0 ) + 13\\\\y = 13 \cos (\dfrac{x}{13} ) + 13[/tex]
