Tammy bought 24 apples to feed her horse. She wants to give her horse 2 apples a day. Tammy said that after 10 days she will hav

kipiarov [429]

Yes she is correct..
the reason why is because if she gives her horse 2 apples a day for 10 days, she will have spent 20 apples.
and so to get the number of apples she has remaining after 10 days, just subtract 20 from 24:
24-20 = 4
and you get four. That means that after 10 days she will indeed have 4 apples left

the lengths of the side of a rectangular window have the ratio 1.7 to 1 the area of the window is 2,720 sqaure inches what are d

nignag [31]

Answer:

$Lenght: 68\ in\\\\Width: 40\ in$

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght and "w" is the width.

You know that the ratio of the sides of the rectangular window is:

$1.7:1$

Then, let be $x$ the width (in inches) of the rectangular window and $1.7x$ the lenght (in inches) of the rectangular window.

Knowing that the area of the window is 2,720 square inches, you can know that:

$(1.7x)(x)=2,720$

Now you must solve for "x" in order to find the width:

$(1.7x)(x)=2,720\\\\1.7x^2=\\\\x=\sqrt{\frac{2,720}{1.7} }\\\\x=40$

Finally, the lenght is:

$1.7x=1.7(40)=68$

Question 15 (1 point)

zloy xaker [14]

Answer:

The value of k is 12.57
Radius of a seventeenth-century cannonball is 2.999 inches which can be rounded off to 3

Step-by-step explanation:

Let s be the surface area and r be the radius

Then according to given statement

s∝r²

Removing the proportionality symbol introduces k, the constant of proportionality

$s = kr^2$

Now

A soap bubble with a 0.75 in. radius has a surface area of approximately 7.07 square inches.

Putting in the equation

$7.07 = k (0.75)^2\\7.07 = k * 0.5625\\k = \frac{7.07}{0.5625}\\k = 12.5688..\\k = 12.57$

The euqation beomes

$s = 12.57r^2$

Putting s = 113.1 in the equation

$113.1 = 12.57r^2\\r^2 = \frac{113.1}{12.57}\\r^2 = 8.99761...\\\sqrt{r^2} = \sqrt{8.9976..}\\r = 2.9996..$

Hence,

The value of k is 12.57
Radius of a seventeenth-century cannonball is 2.999 inches which can be rounded off to 3

A triangle has coordinates A (1,5), B (-2,1) and C (0,-4). What are the new coordinates if the triangle is dialated with the sca

yan [13]

Answer:

A(0.2,1)

B(-0.4,0.2)

C(0,-0.8)

Step-by-step explanation: multiply the coordinates by the number of dilation. In this case you would multiply the coordinates by 1/5
