A recipe uses 3 cups of flour 2 cups of sugar write the ratio of flour to sugar. Then write the related rate and unit rate.
Answer:
The ratio of a certain thing say A to another B is written as A:BTo write this as a rate, put the left value A on top of the right value B so that [tex]A:B=\frac{A}{B}[/tex] So the rate is [tex]\frac{(3)cupsofflour}{(2)cupsofsugar}[/tex] read as 3 cups of flour per 2 cups of sugarThe unit rate means write the fraction as a rational non-fraction number so [tex]\frac{3}{2}=1.5\\so\\(\frac{3}{2})cupsofflour/cupsofsugar = (1.5)cupsofflour/cupsofsugar[/tex]Can somebody answer these 2 questions
Answer:
2. 12.08
3. 7.74
Step-by-step explanation:
a squared + b squared = c squared
2. 5 squared = 25, 11 squared = 121, 25 + 121 = 146, the squre root of 146 is 12.08
3.19 squared = 361, 421 - 361 = 60 60 squared = 7.74
Answer:
For 2 the answer is 12. For 3 the answer is 28.
Step-by-step explanation:
These may be wrong but hopefully they are correct
My work:
[tex]5^2+11^2=146[/tex] then [tex]\sqrt{146} = 12.08[/tex]
[tex]\sqrt{421}=20.5[/tex] [tex]19^2+20.5^2=781.25[/tex] then [tex]\sqrt{781.25} =28[/tex]

Consider the function f(x) = 3x − 2. Select True or False for each statement. The y-intercept is 2. A True B False The x-intercept is 2 3 . A True B False The slope is 3. A True B False
Answer: A false, B true, C true
Step-by-step explanation:
A) intercept with y axis
That means x=0
y= 3*0-2
y= -2 So A is false
B) intercept with x axis
That means y=0
0= 3x-2
2=3x
2/3= x B is true
C) The form of linear function is
f(x)= mx +n, where m is the slope
In this case m= 3 so C is true
1. The y - intercept is 2. ⇒ False
2. The x - intercept is 2/3 ⇒ True.
3. The slope is 3. ⇒ True.
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The function is,
f (x) = 3x - 2
Now,
1. To find the y - intercept we substitute x = 0 in the function.
Hence, The y - intercept is,
f (x) = 0 - 2
f (x) = - 2
Hence, The statement y - intercept is 2 is False.
2. To find the x - intercept we substitute f(x) = 0 in the function.
Hence, The y - intercept is,
f (x) = 3x - 2
0 = 3x - 2
3x = 2
x = 2/3.
Hence, The statement x - intercept is 2/3 is True.
3. We know that;
The slope intercept form of the line is,
y = mx + b
Where, m is slope of the line.
And, b is y - intercept.
So, By comparing with the function f (x) = 3x - 2 , we get;
Slope (m) = 3
Hence, The slope is 3 is True.

The freefall function to calculate velocity, v, of an object that begins at rest and falls for distance d is v(d) = 2gd , where g is the acceleration due to gravity. The Storm Runner roller coaster at Hershey Park drops 55 m. Use the free-fall function to calculate to the nearest tenth its velocity at the end of the freefall. Use g = 9.8 m/s2 Enter your answer, rounded to the nearest tenth, in the box. v(55) = m/s
9514 1404 393
Answer:
32.8 m/s
Step-by-step explanation:
The function is actually ...
[tex]v(d) = \sqrt{2gd}[/tex]
Filling in the given values, the velocity is about ...
[tex]v(55) = \sqrt{2\cdot9.8\cdot55}=\sqrt{1078}\approx32.8\text{ m/s}[/tex]
The velocity at the end of the free-fall is about 32.8 meters per second.

Can you tell me the slope for each graph i got the first 2
answers are at the bottom
Answer: 1) m=2, 2) m=-2/3, 3) m=-2/5 4) m=-1/2 5) m=4 6) m=1
Step-by-step explanation:
2, 3, & 4 are all declining so they are going to be negative and 1, 5, & 6 are all inclining so they’re positive. When you put the amount you go up vertically from point to point over the amount you travel horizontally between each point you should get the slope for each graph.

Result = 0.0045
Step-by-step explanation:
Given
[tex]0.09 * 0.05[/tex]
Required
Determine the result
Following Charlie's steps:
0.09 is a 2 decimal placed digit
and
0.05 is a 2 decimal placed digit
So, the product is as follows:
9 --------- 2 decimal place
5 --------- 2 decimal place
------------------------------------------
45 --------- 4 decimal place
Shifting the decimals in 45 to 4 decimal places will give us: 0.0045
Hence, the final answer is 0.0045
