write the fraction as a product of a whole number and a unit fraction 5/5
Answer:
1 and to find a unit fraction of an amount, divide the amount by the denominator of the fraction. For example to find 1/3 of 18, divide 18 by 3. 18 ÷ 3 = 6 and so, one third of 18 is 6. /3 is a unit fraction with a denominator of 3.

Prasad worked 15 hours this week and earned $195. Assuming he is paid by the hour, how much will Prasad earn next week if he is scheduled to work 12 hours?
Answer:
$156
Step-by-step explanation:
First you must find out the number of dollars Prasad receives per hour.
Since he earns $195 in 15 hours we can do 195/15 = 13 to find out the amount of dollars he earns per hour which is $13.
Next we must find out how much money he receives when he work for 12 hours so we simply do 13 (payment per hour) * 12 (amount of hours he works) which will give us $156!
This makes sense cuz 156 is a little bit less than 195 and ofc 12 is a little bit less than 15!
Prasad earn $156 next week if he is scheduled to work 12 hours
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Prasad worked 15 hours this week and earned $195
We have to find the amount earned by prasad for work 12 hours
Let us form an proportional equation.
Let x be the amount earned for 12 hours
15/195 = 12/x
Apply cross multiplication
15x=195(12)
15x=2340
Divide both sides by 15
x=2340/15
x=156
Hence, Prasad earn $156 next week if he is scheduled to work 12 hours

In ΔRST, s = 620 cm, r = 210 cm and ∠R=17°. Find all possible values of ∠S, to the nearest 10th of a degree.
Answer:
1843:6754.9709254546.,657675
Step-by-step explanation:
The measure of the angle of the triangle is calculated by the law of sines and m∠S = 59.7°
What is the law of sines?The relationship between a triangle's sides and angles is provided by the Law of Sines. Trigonometry's law of sines can be expressed as a/sinA = b/sinB = c/sinC, where a, b, and c are the lengths of the triangle's sides, and A, B, and C are the triangle's respective opposite angles.
Law of Sines :
a / sin A = b / sin B = c / sin C
Given data ,
Let the triangle be represented as ΔRST
Now , the measure of s = 620 cm
The measure of side r = 210 cm
And , the measure of angle m∠R = 17°
From the law of sines , we get
a / sin A = b / sin B
On simplifying , we get
sin ( 17 )° / 210 = sin ( S ) / 620
Multiply by 620 on both sides , we get
sin ( S ) = ( 620 / 210 ) x 0.2923717
On further simplification , we get
sin S = 0.86319265203
Taking inverse on both sides , we get
S = sin⁻¹ ( 0.86319265203 )
S = 59.68°
S = 59.7°
Therefore , the value of S is 59.7°
Hence , the measure of angle m∠S = 59.7°

David compro 23 boligrafos y 15 lapizes, cada boligrafo le costo 14 pesos y cada lapiz 9. ¿Cuanto gasto en total David?
Answer:
457 pesos
Step-by-step explanation:
From the above question, we are told that:
David bought 23 pens and 15 pencils.
Each pen = 14 pesos
Each pencil = 9 pesos
The amount of money David spent in total =
(23 × 14 pesos) + (15 × 9 pesos)
= 322 pesos + 135 pesos
= 457 pesos
Therefore, David spent in total 457 pesos

Sandy bought a soft drink for 2 dollars and 5 candy bars. She spent a total of $12. How much did each candy bar cost?
Answer:
If Sandy bought a soft drink for 2 dollars that's 2 dollars subtracted from the total of $12.00 spent
If we have 10 dollars and bought 5 candy bars we would divide so 10 divided by 5 = 2 so each candy bar costed $2 dollars

y=x+ - 4x3
Find the two stationary points
on the graph of y=x4 - 4x3
Answer: [tex](0,0), (3,-27)[/tex]
Step-by-step explanation:
Given
Curve is [tex]y=x^4-4x^3[/tex]
The stationary point on a differentiable function is the points where the differentiation of the function is zero i.e. slope is zero at that point.
Differentiate the curve [tex]f(x)=x^4-4x^3[/tex]
[tex]\Rightarrow f'(x)=4x^3-12x^2[/tex]
Equate it to zero
[tex]\Rightarrow 4x^3-12x^2=0\\\Rightarrow 4x^2(x-3)=0\\\Rightarrow x=0,0,3[/tex]
Put [tex]x=0,3[/tex] in the function [tex]f(x)=x^4-4x^3[/tex]
[tex]\Rightarrow f(0)=0\\\Rightarrow f(3)=3^4-4(3)^3\\\Rightarrow f(3)=81-108\\\Rightarrow f(3)=-27[/tex]
Therefore, the stationary points are [tex](0,0), (3,-27)[/tex]
Consider function f.
Which statement is true about function f?
A.
The function is continuous.
B.
As x approaches positive infinity, approaches positive infinity.
C.
The function is increasing over its entire domain.
D.
The domain is all real numbers.
Answer:
Step-by-step explanation:
Check for continuity by evaluating 2^x and -x^2 - 4x + 1 at the break point x = 0: 2^0 is 1 and -x^2 - 4x + 1 is also 1, so these two functions approach the same value as x approaches 0.
Now do the same thing with
-x^2 - 4x + 1 and (1/2)x + 3 at x = 2; the first comes out to -11 and the second to 4. Thus, this function is not continuous at x = 2.
We must reject statement A.
Statement B: as x increases without bound, (1/2)x + 3 also increases without bound. This statement is true.
Statement C: False, because the quadratic -x^2 - 4x + 1 has a maximum at
x = -b/[2a], or x = -(-4)/[-2], or x = -2
Statement D: True: there are no limitations on the values of the input, x.
The statement B is as x approaches positive infinity f(x) approaches positive infinity is true
What is the definition of the limit?A point or level beyond which something does not or may not extend or pass.
We have to check for continuity by evaluating [tex]2^x[/tex] and [tex]-x^2 - 4x + 1[/tex]
at the break point x = 0
[tex]2^0[/tex]is 1 and [tex]-x^2 - 4x + 1[/tex] is also 1,
So these two functions approach the same value as x approaches 0.
Now do the same thing with
[tex]-x^2 - 4x + 1[/tex]and [tex](1/2)x + 3[/tex] at x = 2;
The first comes out to -11 and the second to 4.
Thus, this function is not continuous at x = 2.
We must reject statement A.
for B we have as x increases without bound,
[tex](1/2)x + 3[/tex]
also increases without bound.
Therefore the statement B is true statement.
Statement C is False,
because the quadratic[tex]-x^2 - 4x + 1[/tex] has a maximum at
[tex]x = -b/[2a],[/tex]
[tex]x = -(-4)/[-2],[/tex]
[tex]x=-2[/tex]
There are no limitations on the values of the input, x.
D is also false negative number are in real numbers.
Therefore,the statement B is as x approaches positive infinity f(x) approaches positive infinity is true
