The answers is A x=4.5y because for whatever y is you multiply it by 4.5 and it gives you your x. Trust me. They all match too; I checked.

Answer:

A. y = 4.5x

Step-by-step explanation:

y is the length of the fish and x is the time, by checking each equation with values in the table you can see that this is the one that represents the relationship.

Example using (4 yrs, 18 cm):

A: 18 = 4.5(4) ✅

B: 4 = 4.5(18) ❌

C: 4 = 9(18) ❌

D: 18 = 9(4) ❌

Hey guys I need help on maths.

Pepsi [2]

Answer:

x=122°

Step-by-step explanation:

sum of all interior angles in a quadrilateral = 360°

then ,

119+105+78+m = 360

m = 58

....

m+ x = 180 ( linear pair)

58+x = 180

x = 122

Alexa can blow 15 balloons in 20 minutes. Sara can blow 18

mylen [45]

rate of blowing balloons of Alexa = 15/20 = 0.75

rate of blowing balloons of Sara = 18/25 = 0.72

rate of blowing balloons of Shirley= 16/21 = 0.76

rate of blowing balloons of Sam = 12/23 = 0.52

from above calculation we concluded Shirley can blow balloons at the fastest rate!

What is the slope of this line?

nataly862011 [7]

Answer: $-\frac{8}{5}$

Remember: RISE/RUN (y/x). Lines that are increasing have a positive slope, and lines that are decreasing have a negative slope.

You can find the slope in two ways:

1. Useful if the line is graphed: count the units between 2 points on the line.

Let's use the points (-1, 4) and (4, -4).

(-1, 4) is 8 units higher than (4, -4) and 5 units to the left of (4, -4).

Because the line is decreasing, the slope is negative.

Therefore, the slope is $-\frac{8}{5}$ .

2. Useful if the line is not graphed: find the difference between the y-coordinate values divided by the difference of the x-coordinate values.

Let's use the points (-1, 4) and (4, -4).
$\frac{-4 - 4}{4 - (-1)} = \frac{-8}{5}$

Therefore, the slope is $-\frac{8}{5}$ .

A pharmaticeutical company is making a new medicine capsule shaped like a cylinder with a half sphere at each end. The

DerKrebs [107]

Answer:

339.12 cubic millimeters

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The volume of the figure is equal to the volume of the two hemispheres (one sphere) plus the volume of the cylinder

step 1

Find the volume of the cylinder

The volume is given by

$V=Bh$

where

B is the area of the base of cylinder

h is the height of cylinder

we have

$B=\pi r^{2}$

we have

$h=8\ mm$

$r=6/2=3\ mm$ ----> the radius is half the diameter

$B=(3.14)(3)^{2}$

$B=28.26\ mm^2$

substitute

$V=(28.26)(8)=226.08\ mm^3$

step 2

Find the volume of the sphere

The volume is given by

$V=\frac{4}{3}\pi r^{3}$

we have

$r=6/2=3\ mm$ ----> the radius is half the diameter

substitute

$V=\frac{4}{3}(3.14)(3)^{3}=113.04\ mm^3$

step 3

Adds the volumes

$226.08+113.04=339.12\ mm^3$
