Answers
Answer:
5 3/4 hours
Step-by-step explanation:
They drove 3 1/2 hours then 2 1/4 hours. We need to find the total of these to find how long this part of the trip was
(3 + 1/2) + (2 + 1/4) = 5 + 1/2 + 1/4
For 1/2, we can multiply both the numerator and denominator by 2 to get
1/2 = 2/4
Substituting that in, we get
5 + 2/4 + 1/4
= 5 + 3/4 hours

Is a 39 Celsius body temperature higher than normal 98 Fahrenheit??
Yes or No
Answers
Answer:
Yes.
Step-by-step explanation:
According to medical science, a body temperature considered normal (that is, below fever) in degrees Fahrenheit is 98ºF, while its equivalent in degrees Celsius is 36.6ºC. Therefore, a body temperature of 39ºC is higher than 98ºF, being equivalent to 102.2ºF.
This is verified by applying the conversion formula from Celcius to Fahrenheit:
(39 x 9/5) + 32 = X
39 x 1.8 + 32 = X
70.2 + 32 = X
102.2 = X

Help Please!!! And can you explain how you got the answer?
Answers
Answer:
x=25
y= 64.5
Step-by-step explanation:
When lines are parallel, 2x=2(the number)
But, 2 isn't an angle. However, 50degrees is congruent to 2 since they are verticle angles.
2x=50
x=25
When lines are parallel, 2y+1=1(the number)
But, 1 doesn't have a verticle angle. However, 180-50 would be equal to 1
180-50=2y+1
130=2y+1
129=2y
y= 64.5

Answers
Ramona went out with her 3 sisters, they spent $58 plus 9% tax on their meal. They also left 15% tip. If they divided up the bill evenly, how much did each of them spend?
Solution:[tex] \frac{58 + 58(9\% + 15\%)}{3} [/tex]
[tex] = \frac{58 + 58(0.09 + 0.15)}{3} [/tex]
[tex] = \frac{58 + 58 \times 0.24}{3} [/tex]
[tex] = \frac{58 + 13.92}{3} [/tex]
[tex] = \frac{71.92}{3} [/tex]
[tex] = 23.97[/tex]
Answer:Each of them did spend $23.97

Clare subscribes to an online music streaming service
for a yearly fee of $96. Starting next month, there will
be a 12% increase in the fee.
The ad for another music streaming service is shown
below. Should Clare switch? Explain.
Answers
Answer:
She should go with service 2 because it is, cheaper. Service 1 cost $107.52, but service 2 cost only $105.
Step-by-step explanation:
Cost now+increase$=new cost
(Part=percent*whole)
Increase=percent increase*cost now
i=12%*$96
i=0.12*96=$11.52
$96+11.52=107.52
Service two⬇️
8.72*12=$105
Yes Clare should switch to service 2 because; cheaper it costs only $105 which is lesser than $107.52
How to Calculate Yearly Fee?
To find the new cost, we will use the expression;
New Cost = Present Cost + increase
However,
Increase = percentage increase * present cost
Increase = 12% * $96
Increase = 0.12 * 96
Increase = $11.52
Thus;
New Cost = $96 + 11.52
New Cost = $107.52
For Service two;
We are told that digital streaming costs $8.75 per month. Thus;
Cost = 8.75 * 12
Cost = $105

find all the real and complex zeros of f(x)=x^3-7x^2+4x-28
Answers
Answer:
For [tex]x \in\mathbb{C}[/tex]
[tex]x = -2i[/tex]
[tex]x = 2i[/tex]
[tex]x = 7[/tex]
Step-by-step explanation:
[tex]f(x)=x^3-7x^2+4x-28[/tex]
For [tex]f(x) = 0[/tex]
[tex]x^3-7x^2+4x-28 = 0[/tex]
We can easily factor the expression [tex]x^3-7x^2+4x-28[/tex] by grouping.
[tex]x^3-7x^2+4x-28 = (x^3-7x^2)+(4x-28) = x^2(x-7)+4(x-7) = \boxed{(x^2+4)(x-7) }[/tex]
Now we have
[tex](x^2+4)(x-7) = 0[/tex]
Therefore,
[tex]x^2+4 = 0 \text{ or } x-7 = 0[/tex]
So,
[tex]x^2 = -4 \implies x = \pm\sqrt{-4}[/tex]
Once [tex]\sqrt{-1} = i[/tex]
[tex]x = \pm\sqrt{-4} = \pm\sqrt{4}\sqrt{-1} = \pm 2i[/tex]

Solve. 3k -4 > 60 – k
Answers
Answer:
[tex]3k - 4 > 60 - k \\ = 3k + k > 60 + 4 \\ = 4k > 64 \\ = k > \frac{64}{4} \\ = k > 16[/tex]
Answer:
k > 16
Step-by-step explanation:
Solve it like an equation solving for k
Move the -4 to the other side by adding it to both sides.
3k -4 plus 4 > 60 plus 4 - k
You get 3k > 64 - k
now move the k from the right to the left by adding both sides by k
3k plus k > 64 - k plus k
You get 4k > 64
Now divide both sides by 4 so you get k alone on one side to solve for the inequality
4k/4 > 64/4
k > 16
