Answer:
6 7/8
Step-by-step explanation:
Since 1 cup of rice is added to 2 3/4 water
We are to determine the Amount of water to be to 2 1/2 cups of rice
Let the unknown number for water be x
So let's solve
1 cup of rice=11/4 water
5/2 cup of rice=x water
Cross multiply
x=5/2×11/4
x=55/8
X=6 7/8
Therefore,6 7/8 water is needed
The height and weight of several adults were recorded:

It was discovered that this can be modeled by the equation
y = 50.2x−140
where x is height in feet and y is weight in pounds.
What height corresponds to a weight of 130 pounds? Round to the nearest hundredth.
A 6.25 ft B 5.85 ft C 6.68ft D 5.38 FT
Answer:
D ) 5.38 ft
Step-by-step explanation:
Plug y as the weight
130 = 50.2x -140
add 140 to both sides
270 = 50.2x
divide by 50.2
x = 5.37848606
5.37848606 rounds to 5.38

f a tennis ball has a diameter of 10, What is the volume of the tennis ball?
Answer:
294.375 or 294.38
Step-by-step explanation:
Volume of a circle: [tex]\frac{3}{4}[/tex]πr³
If the diameter of a circle is 10, the radius is 5 .
5³ = 125
125 x 3.14 = 392.5
392.5 x [tex]\frac{3}{4}[/tex] = 294.375 or 294.38
The sum of two numbers is 34. The smaller number is 20 less than the larger number. What are the numbers?
Answer:20 and 14
Step-by-step explanation:
Final answer:
The two numbers sought are 27 and 7, with 27 being the larger number and 7 being the smaller number, 20 less than 27. This is determined by setting up a system of equations based on the given conditions and solving for the two unknowns.
Explanation:
The question involves finding two numbers based on the conditions given: the sum of the two numbers is 34, and the smaller number is 20 less than the larger number. Let's denote the larger number as x and the smaller number as y. According to the conditions, we have two equations: x + y = 34 and y = x - 20.
We can substitute the second equation into the first to find the value of x: x + (x - 20) = 34, which simplifies to 2x - 20 = 34. Adding 20 to both sides gives us 2x = 54, and dividing both sides by 2 yields x = 27. Now that we know the larger number, we can find the smaller number by substituting x into the second equation: y = 27 - 20, which gives y = 7. Therefore, the two numbers are 27 and 7.

Answer:
1. a=1 b=9 c=20
(x+5) (x+20)
2. a=1 b=2 c=-8
(x-2)(x+4)
Step-by-step explanation:
When you use the box method, follow these steps (only usable when a=1)
(i'll be using x^2+9x+20 as an example)
be sure to understand that the formula is ax^2+bx+c
1. the top left corner is a, so put x^2
2. the bottom right is the c, or the y intercept. that would be 20 when using x^2+9x+20
3. find 2 numbers that when multiplied equal c and when added equal b. in this problem, 4(5)=20 and 4+5=9, so 4 and 5 belong in the remaining 2 boxes. make sure to add the x after each term, since these terms are b.
4. find to common term in each row of the box (x^2 and 4x share x, and 5 and 20 share 5) and then the common terms in the columns (x^2 and 5x share x and 4 and 20 share 4)
this should give you (x+4)(x+5)

Which dimensions can create only one unique triangle?
Answer:
case A. Three angles measuring 25,65,and 90
sum of a internal angles=25+65+90-----> 180° is ok
That dimensions can create infinity similar triangles
case B. Three angles measuring 50,50,and 50
sum of a internal angles=50+50+50----> 150° is not a triangle
therefore
That dimensions cannot create a triangle
case C. Three sides measuring 5 in,12 in,and 14 in
Applying the Triangle Inequality Theorem
5+12>14 -- > is ok
14+5>12 --- > is ok
12+14>5 --- > is ok
That dimensions can create only one unique triangle

(1) 3. Suppose Kaitlyn wants to make the statement that 25% of the 24 students
she sampled raised over a certain amount for the charity. What is that
amount? Explain.
Answer:
That amount is 6 STUDENTS out of 24 students.
Step-by-step explanation:
Please see the attached files for more information.
Final answer:
To calculate the amount representing 25% of the 24 students Kaitlyn sampled, an equation using equivalent fractions and cross-multiplication is set up. The equivalent fractions are 25/100 and x/24. After cross-multiplying and solving for x, we find that 6 students (x) raised more than a certain amount for the charity.
Explanation:
If Kaitlyn wants to make the statement that 25% of the 24 students she sampled raised over a certain amount for the charity, we would need to determine what number of students that percentage represents. To calculate this, we use the phrase “part over total, times one hundred, equals percent.” Applying this to Kaitlyn's situation, we would set up an equation using equivalent fractions and then cross-multiply to find the part.
For the equivalent fraction, we have 25/100 (since 25% is the same as 25/100) and we let the part be x/24 (where x is the number of students who raised over a certain amount). The equation would then be 25/100 = x/24.
By cross-multiplying, we have 25 * 24 = 100 * x, which simplifies to 600 = 100x. Therefore, after dividing both sides of the equation by 100, we find that x = 6. Thus, Kaitlyn is saying that 6 out of the 24 students raised more than a certain amount for the charity.

Step-by-step explanation:
:) It's 100% right!!!
The amount of methane emissions, in millions of metric tons, from 2002 to 2008 is shown. So, the answer is 1) Quadratic 2) 711 metric tons and 3) Most Likely to Increase.
What is the fitting of the curve for a data plot?When the data shows some trend, either linear (making a line), or non-linear (a predictable curve), we fit a mathematical curve on that data set, as a representative of the pattern in that data set, to predict the output based on the inputs.
A 2-column table with 7 rows.
The first column is labeled year with entries 2002, 2003, 2004, 2005, 2006, 2007, and 2008.
The second column is labeled methane (millions of metric tons) with entries 673.3, 660.6, 661.6, 669.2, 678.5, 690.9, and 724.2.
1) A regression model that best models the data would be the Quadratic function.
2) The amount of methane emissions in 2000 was about million metric tons.
It would be 711 metric tons
3) The amount of methane emissions in the years immediately following 2008 would most likely to Increase.

Convert the angle 0 = 345° to radians.
6. 02 rad. is the value of conversion of the angle 0 = 345° to radians.
Here, we have,
given that,
Convert the angle theta = 345° to radians.
To convert from degrees to radians, multiply the number of degrees by π/180.
This will give you the measurement in radians.
If you have an angle that's 90 degrees, and you want to know what it is in radians, you multiply 90 by π/180. This gives you π/2.
here, angle = 345°
We convert degrees to radian by multiplying by (π/ 180)
=(345)×(π/ 180)
=( 345/180)×(π)
=1.9166π
=1.9166×3.14
=6.018 rad
≈6.02 rad .

What is 119 times 31%
Answer:
61.69?
Step-by-step explanation:
Are you asking what 31% of 119 is? If so, then the answer would be 61.69.
Because (119)0.31=61.69
(To make a percent, you take a decimal out of 1, and multiply. 0.31 would be 31, because we would multiply it by 100, becuase you can only get to 100%. Then you woukd do the opposite, reverse it by dividing by 100. Which then, you would get 0.31)

the the square of the measure of the tangent is equal to the product of the external part of the secant and the entire secant, that is
x² = 4(4 + 9) = 4 × 13 = 52 ( take the square root of both sides )

The value of the z-score is 1.33.
What is a z-score?The z-score is defined as the mean (average) values, measured in terms of standard deviations from the mean.
The formula is used to calculate z-score is;
Z-score = (X-μ)/σ
We have, mean = 7 and σ =3.522 and X is 11.7.
Substitute all the values in the formula;
Z-score = (X-μ)/σ
= (11.7-7)/3.52
= 4.7/3.52
= 1.33
Hence, the value of the z-score is 1.33.
