Answer: 3:7
Step-by-step explanation:
There are 3 stars for every 7 circles, thus the ratio is 3:7.
Answer:
3 : 7.
Step-by-step explanation:
For every 3 stars, there are 7 circles. If 3 stars is written first, you'll need to write 3 first in your answer, and 7 second.
This is what it would look like: 3 : 7
With ratios, you could also write,
3 to 7
or
3 / 7
But 3 : 7 is most common :)

bcz root of 121 is 11. then 2/3 +11 will give you a rational number.
Answer:
2/7 + square root of 121 (the third one)
Step-by-step explanation:
a rational number is a number where if you write it as a fraction, both the numerator and denominator are integers (numbers like 1 and 2 but not like 3.4 or 5.6)
the equation simplified a bit looks like this:
2/7 + 11/1
anddd so all the numbers are integers which means that expression is correct :3
Graph the function.
f(x)=−1/5x+4
Use the Line tool and select two points to graph.
Answer:
The coordinates are: (1,3.8), (2,3.6)
Now, plotting these points on graph as shown in figure.
Step-by-step explanation:
We need to graph the function: [tex]f(x)=-\frac{1}{5}x+4[/tex]
For drawing the graph, we need x and y coordinateness.
The can be found as following:
If we put x =1 in the given function, we will get:
[tex]f(x)=-\frac{1}{5}x+4\\Put\:x=1\\f(x)=-\frac{1}{5}(1)+4\\f(x)=-\frac{1}{5}+4\\f(x)=\frac{-1+4*5}{5}\\f(x)=\frac{-1+20}{5}\\f(x)=\frac{19}{5}\\f(x)=3.8[/tex]
So, we get when x =1 f(x) or y = 3.8
Now for finding second point, we put x =2 in the given function
[tex]f(x)=-\frac{1}{5}x+4\\Put\:x=2\\f(x)=-\frac{1}{5}(2)+4\\f(x)=-\frac{2}{5}+4\\f(x)=\frac{-2+4*5}{5}\\f(x)=\frac{-2+20}{5}\\f(x)=\frac{18}{5}\\f(x)=3.6[/tex]
So, we get when x =2 f(x) or y = 3.6
The coordinates are: (1,3.8), (2,3.6)
Now, plotting these points on graph as shown in figure.
You find 1 on x-axis and 3.8 on y-axis for first point (1,3.8)
Similarly You find 2 on x-axis and 3.6 on y-axis for second point (2,3.6)

Now let's assume that you have a newer toilet that uses 6 L per flush, but you are considering upgrading to a dual-flush toilet. If you flush the toilet four times per day, but three of those times you could use the 3 L flush, how many liters of water would you save in 1 year
Answer: 3,285 Liters
Step-by-step explanation:
In the actual case, all your flushes consume 6 L of water.
You flush 4 times per day, then you consume 4 times 6 L per day, this is:
4*6L = 24 L per day.
And in one year there are 365 days, then in one year you consume:
365*24 L = 8,760 L
Now, if you upgrade the toilet, now per day you use:
one time 6 L and 3 times 3 L
Then in day, you use:
1*6 L + 3*3 L = 6L + 9L = 15L
And in the complete year, you will use 365 times that, which is:
365*15 L = 5,475 L
The amount of water that you would save is equal to the difference between the amount that you use in one year with no upgrade (8,760 L) and the amount that you would use in a year if you upgraded your toilet ( 5,475 L)
The difference is:
D = 8,760 L - 5,475 L = 3,285 L
This means that, in this situation, you would save 3,285 liters of water per year if you upgrade your toilet.
Find the vertex of the parabola. y = negative 4 x squared + 24 x minus 35 a. ( -3, 1) c. ( 3, 1) b. ( -3, -1) d. ( -1, -3)
Answer:
(3, 1)
Step-by-step explanation:
y = -4x² + 24x - 35
Find the vertex by using the formula:
(h, k) → [tex]\displaystyle \Big [ -\frac{b}{2a}, \ f \Big (-\frac{b}{2a} \Big ) \Big ][/tex]In this problem, we have:
a = -4 b = 24 c = -35Using 24 for b and -4 for a, we can substitute these values into the vertex formula:
[tex]\displaystyle -\frac{b}{2a} \rightarrow -\frac{24}{2(-4)} = \frac{-24}{-8} = 3[/tex]The h-value for the vertex is 3.
Now let's plug 3 back into the standard form equation to solve for the k-value of the vertex.
[tex]-4x^2 + 24x - 35 \rightarrow -4(3)^2+24(3)-35 = -36 + 72 - 35 = 1[/tex]The k-value for the vertex is 1.
The vertex of the parabola is (3, 1).
Estimate the product of 2 & 4/11 and 16 & 1/5.
A. about 2 × 16 = 32
B. about 2 × 14 = 28
C. about 3 × 16 = 48
D. about 3 × 14 = 42
Answer:
a
Step-by-step explanation:
Determine what is closer to 2 4/11.
you would- 4/11 to get 2
you would +6/11 to get 3.
So 2 is closer
Do the same with 16 1/5
16 is closer
therefore, it is 2*16=32

Answer: 77/3 or 25.67
Step-by-step explanation:
3 1/2 * 11/3
3 * 2+1=7
7/3 * 11/3
7 * 11= 77
3 stays the same
77/3 or 25.67
Answer:
4 2/3
Step-by-step explanation:
You need to turn the fractions into improper fractions
To do that you multiply the whole number by the denominator and add the numerator, doing that will give you your new numerator, but the denominator stays the same
3 1/2. 3×2 = 6. 6+1=7 3 1/2 = 7/2
1 1/3. 1×3 = 3. 3+1 = 4. 1 1/3 = 4/3
Then multiply both numerator by each other and do the same for the denominators
7×4 = 28
2×3 = 6
28/6
Then simply it
28/6 = 4 2/3

(4,10) and (-2,-5) slope
Answer/Step-by-step explanation:
6. Given, (-5, 2) and (1, -2):
[tex] \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_2} [/tex]
[tex] = \frac{-2 - 2}{1 - (-5)} [/tex]
[tex] = \frac{-4}{6} [/tex]
[tex] = \frac{-2}{3} [/tex]
9. Given, (4, 10) and (-2, -5):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_2} [/tex]
[tex] = \frac{-5 - 10}{-2 - 4} [/tex]
[tex] = \frac{-15}{-6} [/tex]
[tex] slope = \frac{5}{2} [/tex]
