I Had Also Taken The Test And It Was 1 7/18 In Mixed Numbers.
The expression 4(19 + e2) + 3f at e = 13 and f = 16 is 804.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, we have to Evaluate the expression 4(19 + e2) + 3f when e = 13 and
f = 16 is the same as replacing the numerical values of e and f in the expression
4(19 + e2) + 3f which is,
= 4(19 + 13²) + 3×16.
= 4(19 + 169) + 48.
= 4(189) + 48.
= 756 + 48.
= 804.

Answer:
-4
Step-by-step explanation:
We are given the equation:-
[tex] \displaystyle \large{x + Cy = \frac{1}{4} }[/tex]
Since we wants to find the value of C that makes the line pass y-intercept which is -1/16.
When we talk about y-intercept, our x-value remains 0 and y-value remains any real number.
It can be expressed as (0,b) point where b is any real numbers.
What we have to do is to substitute (0,-1/16) or x = 0, y = -1/16 in the equation so we can find the value of C.
Thus:-
[tex] \displaystyle \large{x + Cy = \frac{1}{4} } \\ \displaystyle \large{0 + C( - \frac{1}{16} ) = \frac{1}{4} } \\ \displaystyle \large{ - \frac{ C}{16} = \frac{1}{4} }[/tex]
Multiply both sides by GCF.
[tex] \displaystyle \large{ - \frac{ C}{16} = \frac{1}{4} } \\ \displaystyle \large{ - \frac{ C}{16} (16)= \frac{1}{4} (16)} \\ \displaystyle \large{ - C= 4 } \\ \displaystyle \large{ C= - 4 }[/tex]
Therefore, C = -4

Find the volume of a right circular cone that has a height of 10.6 m and a base with a
diameter of 18.5 m. Round your answer to the nearest tenth of a cubic meter.
The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,
V = 949.76cm³
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Height of cone = 10.6 m
Diameter of cone = 18.5 m
Hence, We can solve for radius as;
= 18.5/2
= 9.25
We know that;
Volume of a right circular cone is,
V = 1/3(πr²h)
Here, r = 9.25, h = 10.6, π = 3.14,
Hence, We get;
V = 1/3(3.14)(9.25)²(10.6)
V = 1/3(3.14)(85.5625)(10.6)
V = 1/3(2847.86225)
V = 949.287417
V = 949.76cm³
Thus, The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,
V = 949.76cm³

14 over 15 rounded to the nearest tenth
Answer:
0.9
Step-by-step explanation:
14/15 = 0.933333333 IF:
1. You first change it into a decimal by dividing the numerator by the denominator.
14 ÷ 15
2. You will get a recurring decimal.
0.933333333
3. The first digit after the decimal is in the position of the 'tenths'
0.9
4. You should use only two digits after the decimal to calculate
0.93
5. Since the number 3 is less than five, it will change into a zero and get eliminated.
∴ The answer will be = 0.9
In a lottery game, a player picks 9 numbers from 1 to 46. If 8 of the 9 numbers match those drawn, the player wins second prize. What is the probability of winning this prize? Be sure to leave your answer as a reduced fraction in order to earn credit.

probability of winning second prize.
Answer: [tex]\frac{37}{1,101,716,330}\\\\[/tex]
This is the same as writing 37/1101716330
======================================================
Explanation:
Let's say the nine winning numbers are: 1,2,3,4,5,6,7,8,9
Let's further say that if we matched everything from 1 to 8, then we'll win second prize. That ninth value can be anything but 9. So we could have something like one of these examples
1,2,3,4,5,6,7,8,101,2,3,4,5,6,7,8,111,2,3,4,5,6,7,8,12As you can see, there are 46-9 = 37 different choices we can have for that last slot. In other words, there are 37 items in the set {10,11,12,...,45,46} we can pick for that last ninth slot. Note that 46-10+1 = 37. This value will form the numerator of the answer.
------------------------------------------
Now to calculate how many ways there are to select the nine values regardless if we win or lose.
Since order doesn't matter, we use the nCr combination formula.
[tex]_{n} C _{r} = \frac{n!}{r!*(n-r)!}\\\\_{46} C _{9} = \frac{46!}{9!*(46-9)!}\\\\_{46} C _{9} = \frac{46!}{9!*37!}\\\\_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38*37!}{9!*37!}\\\\[/tex]
[tex]_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38}{9!} \ \text{ ... the ``37!'' terms cancel}\\\\_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38}{9*8*7*6*5*4*3*2*1}\\\\_{46} C _{9} = \frac{399,790,821,830,400}{362,880}\\\\_{46} C _{9} = 1,101,716,330\\\\[/tex]
There are slightly over 1 billion ways to select the nine values.
This large value is the denominator of our answer which is [tex]\frac{37}{1,101,716,330}\\\\[/tex]
The 37 up top represents the number of ways to win the second prize we're after, while the massive number in the denominator represents how many ways there are to play the game.
------------------------------------------
Notice that in the jump from step 4 to step 5, shown in the section above, we had the "37!" terms cancel out. What this means is that the prime number 37 is nowhere to be found anywhere in the factorization of 1,101,716,330
Why is this important? Because it tells us that the fraction [tex]\frac{37}{1,101,716,330}\\\\[/tex] cannot be reduced.
Side note: That fraction converts to the decimal form 0.00000003358397 approximately and that converts to the percentage form 0.000003358397%; both of which are very very small numbers. We can see that the odds are definitely stacked against the player.

A motorboat can maintain a constant speed of 47 mph relative to the water. The boat makes a trip upstream to a certain point in 51 minutes; the return trip takes 43 minutes. What is the speed of the current?
9514 1404 393
Answer:
4 mph
Step-by-step explanation:
The ratio of speeds upstream and down is inversely proportional to the ratio of times upstream and down. If we let c represent the speed of the current, the relation can be written ...
(47 +c)/(47 -c) = 51/43
43(47 +c) = 51(47 -c)
94c = 8(47) . . . . . . . . . . . add 51c -43(47)
c = 4 . . . . . divide by 94
The speed of the current is 4 miles per hour.
