Answers

Answer 1

Answer:

9

Step-by-step explanation:

→ Divide the number of red marbles by the ratio of red marbles

12 ÷ 4 = 3

C) 5/24
D) 1/6​

Answers

3+7=10

10/12
simplified (divide by 2) it’s
5/6

the answer is A

Answer:

A. 5/6

Step-by-step explanation:

Since our denominators match, we can add the numerators.

3 + 7 = 10

So 10/12 the answer but simplified would give 5/6

Consider the function given by the graph. What are
these values?
fl-2) =
10) =
f(4) =

Answers

Answer:

f(-2) = 2

f(0) = 4

f(4) = -1

Step-by-step explanation:

Given the graph of a piecewise function:

[tex]\displaystyle\mathsf{f(x) = \left \{ {{x\:+\:4\quad if\:\:x\leq \:0} \atop {-\frac{1}{2}x\:+\:1\quad if\:\:x\: >\:0}} \right.}\\[/tex]

Side note:

I used the method of finding the linear equations in slope-intercept form to establish the piecewise function. First, I solved for the slope by choosing two points in each defined interval. Then, I plugged in the y-intercepts of each interval, for f(x) = x + 4: the y-intercept is (0, 4) where b = 4; for f(x) = -½x + 1, the y-intercept is (0, 1) where b = 1.

Explanation:

There are two methods for determining the range values of the given domain values.  

Method 1: The first method is using the graph to find the corresponding range values of the given domain {-2, 0, 4}.  

Method 2: Alternatively, we could use the rules provided by the piecewise function in evaluating the following domain values.  This post will use the second method (using the piecewise function) to evaluate the input values.

Regardless of the method used, the results will remain the same.

f(-2)

Since the input value is x = -2, then we must use the function, f(x) = x + 4:

f(x) = x + 4

f(-2) = -2 + 4

f(-2) = 2

Therefore, the range value given the domain, x = -2 is 2, or simply: f(-2) = 2.

f(0)

Given the input value is x = 0, then we must also use the function, f(x) = x + 4:

f(x) = x + 4

f(0) = 0 + 4

f(0) = 4

Therefore, the range value given the domain, x = 0 is 4, or  f(0) = 4.

f(4)

Since the input value is x = 4, then we must use the function, f(x) = -½x + 1:

f(x) = -½x + 1

f(4) = -½(4) + 1

f(4) = -2 + 1

f(4) = -1

Therefore, the range value given the domain, x = 4 is -1, or  f(4) = -1.

Yara is trying to find the best price for 8 notebooks.

If 2 notebooks cost $14.00 at Barnyard Books, and 5 notebooks cost $20.00 at The Bookworm, how many dollars will Yara save if she buys 8 notebooks from The Bookworm instead of Barnyard Books?

Answers

Answer:

Yara will save $24.00 if she buys 8 notebooks from bookworm instead of barnyard books.

Step-by-step explanation:

if 2 notebooks = $14.00, then, 14 ÷ 2 = $7.00

Therefore, 1 notebook at Barnyard book is $7.00

She bought 8, so 8×7 = $ 56.00

> She will spend $56.00 at Barnyard book

while at bookworm, 5 notebooks cost $20.00

> 20 ÷ 5 = $4.00

Therefore, 1 notebook at bookworm cost $4.00

She bought 8, so 8×4 = $32.00

> She will spend $32.00

Subtract the total amount that she'll spend on both stores

$ 56.00 - $ 32.00 = $ 24.00

Therefore, Yara will save $24.00 if she buys 8 notebooks from bookworm instead of barnyard books

There are 495 pages in the mathematic book, from this 330 pages are included for the first term. Find the proportion of total pages to allotted pages in simplest form.

Answers

Answer:

330/495 = 2/3

the answer is 2/3

Answer:

3 : 2

Step-by-step explanation:

Total pages : allotted pages = 495 : 330

Find the HCF of 495 and 330

495 = 5 * 3*3*11

330 = 5 * 3 * 2 * 11      

HCF = 5 * 3 * 11 = 165

Divide 495 and 330 by 165

495 : 330 = 3 : 2

Answers

Answer:

π is equivalent to 3.14

Step-by-step explanation:

π is equal to 3.14

Circumfrance = 8.5*2*π

So 8.5 * 2 is 17 times π is 53.38

round to nearest whole number is 53

area is π * radius squared so

8.5 * 8.5 =72.25

A cyclist travels 6.7 km in 30 minutes. What is his average speed in km/h?​

Answers

Answer:

[tex]\implies \footnotesize \text{ Average Speed} = \dfrac{ \text{Total Distance}}{ \text{Total time}} \\ [/tex]

30 min = ½ hr.

[tex]\implies \footnotesize \text{ Average Speed} = \dfrac{ 6.7 \: km}{ \frac{1}{2} \: hr }[/tex]

[tex]\implies \footnotesize \text{ Average Speed} = 6.7 \times 2 \: km/h[/tex]

[tex]\implies \footnotesize \textbf{ Average Speed = 13.4 \: km/h}[/tex]

His rate is 13.4km/ hour

Data;

Distance = 6.7kmTime = 30 minutes

Conversion From Minutes to Hours

To solve this problem, we have to convert his speed from km/min to km/h

[tex]60min =1 hour\\[/tex]

Since his rate is 6.7kmin 30 minutes, let's convert it to hour

[tex]6.7km = 30min\\x km = 1min\\x = \frac{6.7}{30} \\x = 0.223km/min[/tex]

But to convert minutes to hours, we have to divide the time by 60

[tex]0.223\frac{km}{min}*60/1 = 13.4[/tex]

From the calculation above, his rate is 13.4km/ hour
