Write –3/8 as a decimal number.

Answer:

21

Step-by-step explanation:

3 (7) - 2(4) + 8

21 - 8 + 8

13 + 8

21

Answer:

21

Step-by-step explanation:

3k - 2c + 8

k = 7 and c = 4

Substitute the values of k and c in the algebraic expression

3(7) - 2(4) + 8 = 21 - 8 + 8 = 21

Answer:

5 scoops

Step-by-step explanation:

Given

[tex]Feeder = 4\frac{1}{2}[/tex]

[tex]Scoop = \frac{9}{10}[/tex]

Required

Determine the number of scoop in a feeder

To do this, we simply divide the size of the feeder by the size of the scoop as follows;

[tex]Number = \frac{Feeder}{Scoop}[/tex]

[tex]Number = 4\frac{1}{2}/\frac{9}{10}[/tex]

Convert Fractions to improper

[tex]Number = \frac{9}{2}/\frac{9}{10}[/tex]

[tex]Number = \frac{9}{2}*\frac{10}{9}[/tex]

[tex]Number = \frac{9 * 10}{2 * 9}[/tex]

[tex]Number = \frac{90}{18}[/tex]

[tex]Number = 5[/tex]

Hence, there are 5 scoops in a feeder

as in the question 4 students can sit on one bench than 4×3=12 which is equal to the total number of students in class.

Step-by-step explanation:

3 bench are needed for all students

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value

We have

Students in the gym = 12

how many students can sit in 1 bench = 4

Based on the given conditions formulate:

12 ÷ 4 = 3

Hence , 3 bench are needed for all students and option C is correct.

Answer:

I think it's 1/2

Step-by-step explanation:

32+25 is 60 and the total number of students are 50, meaning 10 offer both, and your question says chemistry only so I guess you'll have to subtract the 10 from the 35.

therefore, 25/50= 1/2.

If [tex]y=\frac{x}{2}+1[/tex] then [tex]y_{\perp}=-2x+1[/tex].

The slope in first line is [tex]1/2=0.5[/tex], therefore the slope of perpendicular line must be [tex]-1/0.5=-2[/tex].

Answer:

Step-by-step explanation:

We start by writing a real world problem

The cost of a pack of candle and a dozen of eggs is $12.5 and $11.3 respectively. If Ridwan intends to buy 2 dozen eggs and half pack of a candle, what should be Ridwan's budget.

Next; is to solve the above problem

We continue by listing out the given parameters

A pack of candle = $12.5

A dozen of egg = $11.3

Required

What is the cost of 2 dozen egg and half pack of candle?

We start by calculating the cost of 2 dozen egg

[tex]Cost = 2 * 1\ dozen\ egg[/tex]

[tex]Cost = 2 * \$11.3[/tex]

[tex]Cost = \$22.6[/tex]

Then, we calculate the cost of half pack of Candle

[tex]Cost = \frac{1}{2} * 1\ pack\ of\ candle[/tex]

[tex]Cost = \frac{1}{2} * \$12.5[/tex]

[tex]Cost = \$6.25[/tex]

Lastly, we add up the two costs;

[tex]Total = \$22.6 + \$6.25[/tex]

[tex]Total = \$28.85[/tex]

Answer:

p = 29 and q = -3

Step-by-step explanation:

Using long division, the remainder when we divide by x − 1 is p+q−16.  The remainder when we divide by x + 1 is p−q−20.

Therefore:

p + q − 16 = 10

p − q − 20 = 12

Add the equations together:

2p − 36 = 22

2p = 58

p = 29

Plug into either equation to find q:

q = -3

-53

Step-by-step explanation:

[tex] \frac{( { - 8)}^{2} }{5 - 9} - ( - 1)^2 + 4( - 9) \\ = \frac{64}{ - 4} - 1 - 36 \\ = - 16 - 1 - 36 \\ = - 52 - 1 \\ = - 53[/tex]

Answer:

None of the options seem to be equivalent to 1/8 but A, B, and C all are equivalent.

B:

4/28 = 1/7

C:

5/35 = 1/7

D:

2/8 = 1/4

E:

7/49 = 1/7

F:

7/40 (cannot be further simplified)

I think you may have a typo in your question as there are no answers. However if the question is asking for 1/7, the answers are A, B, C, E.

==================================================

Explanation:

1.5 liters of orange juice

7.5 liters of lemonade

1.5+7.5 = 9 liters total

1.5/9 = 15/90 is the fractional amount of orange juice. Note how I multiplied top and bottom of the first fraction by 10 to get 15/90. This is the same as moving the decimal point 1 spot to the right for each value.

----------

From here you divide both parts by the GCF 15 to reduce

15/15 = 1

90/15 = 6

Meaning 15/90 = 1/6

So 1/6 of the drink is orange juice.

Answer:

3,4,5 is the Pythagorean triplet

Step-by-step explanation:

A pythagorean triplet is when you have 3 consecutive numbers (for example 1,2,3 or 9,10,11). So since they've already given one of the numbers you can try doing trial and error to find out(use different combinations like 3,4,5 or 4,5,6) and see whether the Pythagoras theorem applies to it.

Answer:

The answer would be 8 1/4

Step-by-step explanation:

-5 1/4 + (-3)

let's start with the whole numbers:

-5 + (-3) = -8 because it's just like adding positives but add a negative sign

so then we just add the -1/4 and you get -8 1/4

*you have to put the second number in parentheses because its how you properly write the equation Ex: -2+8+(-3)+(-1 5/6)=...

* also note that when you add two negatives it becomes a positive!!!

t =2654.01465 year

Step-by-step explanation:

Given that the​ half-life of​ carbon-14 is 5600 years and if a piece of charcoal made from the wood of a tree shows only 72% of the​ carbon-14 expected in living​ matter.

we know

[tex]y=a(b)^{t/h}[/tex]

where y= final amount

a= initial amount

b= growth/decay

t= time elapsed

h= half time

plugging the values we get

[tex]0.72 =(\frac{1}{2})^{t/5600}\\[/tex]

taking log on both side

log 0.72 = t/5600 log(1/2)

solving we get t =2654.01465 year

It would be B. Fuction 1 has the larger maximum at (4,1)

Step-by-step explanation:

because the maximum point for Fuction 1 is at (4,1) becuase that the highest point/vertex it goes.

You can use a graph to identify the vertex or you can find the minimum or maximum value algebraically by using the formula x = -b / 2a. This formula will give you the x-coordinate of the vertex. Simply replace the x in your original equation with the value of the x-coordinate and then solve for y.

Answer:

It would be B. Fuction 1 has the larger maximum at (4,1)  because the maximum point for Fuction 1 is at (4,1) becuase that the highest point/vertex it goes.

Answer: Juanita

Step-by-step explanation: The question is referring to ratios of the lemon flavor. Juanita's lemonade is 4:2 and Lydia's is 5:3. 4:2 is a larger ratio than 5:3, so that means that Juanita's recipe has a higher concentration of lemon flavor.
