If you use squares to approximate area,what do you use to approximate volume?
1 rectangles
2 cubes
3 spheres
4 circles
Answer:
cubes
Step-by-step explanation:
because when you find area you would say 2 meters "squared" but when you find volume you woukd say 2 meters "cubed"
The table represents an exponential function.
What is the multiplicative rate of change of the
function?
Х
1
3
.
2.
4
9

9
Answer:
Step-by-step explanation:
An exponential function has a standard form
[tex]y=a(b)^x[/tex] where a is the initial value, b is the rate of growth or decay, and x and y are found in coordinates from the table. We need to solve for b, the rate of change (growth or decay). We will use the first 2 coordinates in the table, namely (1, 6) and (2, 4) to solve for b. We will use a system of equations...2 equations for 2 unknowns. The first equation is found by plugging in a 6 for y and a 1 for x to get:
[tex]6=a(b)^1[/tex] and, solved for a:
[tex]a=\frac{6}{b}[/tex].
In the second equation, we will plug in a 4 for y, a 2 for x and the value for a we just found:
[tex]4=\frac{6}{b}(b)^2[/tex] and, simplified a bit:
[tex]4=\frac{6b^2}{b}[/tex] which finally simplifies to
4 = 6b and
[tex]b=\frac{2}{3}[/tex]. That's the rate of change we are asked to find. We could continue to find the whole equation. Plug in 2/3 for b to solve for a:
[tex]a=\frac{6}{\frac{2}{3} }[/tex] and
[tex]a=\frac{6}{1}*\frac{3}{2}=\frac{18}{2}=9[/tex] and the exponential equation is
[tex]y=9(\frac{2}{3})^x[/tex] that means that we started with 9 of something and it is dying/decaying/depreciating at a rate of 33%

Pythagorean Theorem
Answer:
Pythagorean Theorem is A^2+B^2=C^2
Step-by-step explanation:
which two ratios represent quantities that are proportional help i will mark as brainless
Answer:
A
Step-by-step explanation:
So, lets take all of our ratios, and simplfy them the best we can. Once we do this, we can easily compare and see which ratios are and are not similar.
So lets start with A:
21/28 and 12/16
Lets simplfy each fraction.
The greatest number that goes into the numeraotr and denominator(GCF) of 21/27 is 7. Taking out 7 we get:
3/4
We can do the same with the 12/16. 4 goes into both the numerator and denominator:
3/4
So this would work.
Lets look at the others, and see if any others work as well:
56/64 and 36/48
8 goes into both 56 and 64:
7/8
4 goes into 36 and 48:
9/12
These are clearly different.
Next we have 9/10 and 10/9
We can instantly see that one is bigger than 1, and the other is smaller than 1, so they must be different.
Finally we have 5/7 and 7/14
Again, these are clearly different.
If we give both the same denominator, which can be 14, we get:
10/14 and 7/14
We get 10/14 from 5/7 since we need to multiply both numerator and denominator by 2 so that the 7 becomes 14 in the denominator.
10/14 adn 7/14 are clearly different, so these dont work as well.
Only A, which is 21/28 and 12/16, will work.
Hope this helps!

Answer:
[tex]17\sqrt{2}[/tex] ft
Step-by-step explanation:
take angle b as reference angle
using sin rule
sin 45 = opposite / hypotenuse
[tex]\frac{1}{\sqrt{2} }[/tex] = 17 / BC
BC =17 / [tex]\frac{1}{\sqrt{2} }[/tex]
BC = 17 * [tex]\sqrt{2}[/tex]
BC = [tex]17\sqrt{2}[/tex] ft
Answer:
BC = 17[tex]\sqrt{2}[/tex] ft
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{17}{BC}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
BC = 17[tex]\sqrt{2}[/tex] ft
Solve for X.
-4(3 + 4x) - 8(x + 6) = 12
Please show work
Answer:
-3
Step-by-step explanation:
-4(3+4x)-8(x+6)=12
-12-16x-8x-48=12
-12-48-16x-8x=12
-60-24x=12
24x=-60-12
24x=-72
x=-72/24
x=-3
Answer:
x = -3
Step-by-step explanation:
-4(3 + 4x) - 8(x + 6) = 12
-12 - 16x -8x - 48 = 12
-24x - 60 = 12
-24x = 72
x = -3
There are 4.5 litres of milk in a pot. The chef stirs in 2.5 g of salt and 1.2 litres of water. How much liquid is in the pot?
Answer:
5.7 litres
Step-by-step explanation:
The salt is not a liquid so you do not need to add it in.
4.5 litres + 1.2 litres = 5.7 litres

Step-by-step explanation:
ab - 0.5b when a = 1 and b = 5
Answer:
2.5
Step-by-step explanation:
a = 1
b = 5
ab
= 1 x 5
= 5
0.5b
= 0.5 x 5
= 2.5
ab - 0.5b
= 5 - 2.5
= 2.5
Answer:
2.5
Step-by-step explanation:
ab - 0.5b
a = 1 and b = 5
(1)(5) - 0.5(5)
Multiply (1)(5) = 5
5 - 0.5(5)
Multiply -0.5(5) = -2.5
5 - 2.5
Subtract 5 - 2.5 = 2.5

Bill rented a truck for one day. There was a base fee of $16.95 , and there was an additional charge of 83 cents for each mile driven. Bill had to pay $248.52 when he returned the truck. For how many miles did he drive the truck?
Answer:
279 miles
Step-by-step explanation:
First, subtract the base fee from his total charge:
248.52 - 16.95
= 231.57
Divide this by 0.83 to find how many miles he drove:
231.57/0.83
= 279
So, he drove 279 miles

Javier bought 1/2 liter of soda for his party. Javier's brother bought a liter of soda and Javier's mom bought 200 milliliters of soda. How many total milliliters did Javier have for his party?
Answer:
1,700 milliliters
Step-by-step explanation:
Convert the liters that Javier and his brother got into milliliters.
In 1 liter, there are 1000 milliliters.
So, Javier's brother bought 1000 milliliters of soda.
And, in 1/2 liter of soda, there are 500 milliliters. So, Javier bought 500 milliliters of soda.
Add these two amounts to how much Javier's mom bought:
500 + 1000 + 200
= 1700
So, for his party, Javier has 1,700 total milliliters of soda.
the lenths of the sides of a triangle are in the extended ratio 5:9:10. the perimeter of the triangle is 48 cm. what are the lengths of the sides?
Answer:
What's my age im 1300
Step-by-step explanation:
Answer:
The sides are of lengths 10, 18, 20
Step-by-step explanation:
Perimeter = 48
Lengths of the sides
5:9:10 * (48/(5+9+10) = 5:9:10 * (48/24) = 10:18:20
The sides are of lengths 10, 18, 20
Write the equation for a line Parallel to this one.
y = 3x + 2
a
y = 3x + 2
y = 3x + 7
ос
y = (1/3)x + 7
Od
y = -(1/3)x + 3
Answer:
actually, a and b are correct, as any line is also parallel to itself (a).
b is probably the truly wanted answer, as this line is on a chart visible as a second line and parallel to the first one.
Step-by-step explanation:
the factor of x is also the slope of the line.
for a line to be parallel to another, both need to have the same slope.
the constant number in the equation is the offset of the line from point (0,0) in y direction.
so, b is a parallel line 4 units above the first line.
The perimeter of a rectangle is 32 inches. The length is 1 foot. What is the width of the rectangle in inches? A. 4 inches B. 10 inches C. 15 inches D. 20 inches 12 / 15
Answer:
A. 4 inches
Step-by-step explanation:
Applying,
P = 2(L+W)............. Equation 1
Where P = Perimter of the rectangle, L = Length of the rectangle, W = width of the rectangle.
make W the subject of the equation
W = (P/2)-L............ Equation 2
From the question,
Given: P = 32 inches, L = 1 foot (Convert from Foot to inches), L = 12 inches
Substitute these values into equation 2
W = (32/2)-12
W = 16-12
W = 4 inches.
Hence the right option is A.

9514 1404 393
Answer:
x = 4
Step-by-step explanation:
The parallel lines divide the sides proportionally, so ratios of corresponding sides are the same.
(x +5)/15 = (5x +1)/35
Multiplying by 105, we have ...
7(x +5) = 3(5x +1)
7x +35 = 15x +3 . . . . . eliminate parentheses
32 = 8x . . . . . . . . . subtract 7x+3 from both sides
4 = x . . . . . . . . divide by 8

Emilio plays basketball. During his last 6 games he made 24 out of 60 free
throw shots. If Emilio will have 25 free throws shots in the next games,
about how many he expects to make?
24 out of 60 is 0.4 which is 40%, so to find out how many he would make in 25 throws you multiply 25 by 0.4 then you would get 10 out of 25.
