Answer:

$6

Step-by-step explanation:

Original price of the pineapple = $20

Percentage off = 70%

Amount discounted = 70% of $20

Amount discounted  = 0.7 * 20

Amount discounted  = $14

Sale price = Original price - Discount

Sale price = $20 - $14

Sale price = $6

Hence the sale price was $6

3x = 21

x = 21 ÷ 3

x = 7

Answer: 48 pupils get the bus to the cinema and 36 pupils walk to the cinema.

Step-by-step explanation:

Let's suppose that there are a total of N pupils.

We know that N/4 walk to the cinema.

We know that N/3 get the bus to the cinema.

And the remainder is equal to 60 people.

Then:

N - N/4 - N/3 = 60

N*(1 - 1/4 - 1/3) = 60

N( 12/12 - 3/12 - 4/12) = 60

N*( 5/12) = 60

N = (12/5)*60 = 144

Then the number of pupils that walk to the cinema is N/4, or:

144/4 = 36

And the number of pupils that get the bus is N/3, or:

144/3 = 48.

Answer:

93

Step-by-step explanation:

Given the data:

$79,$ $84,$ $86,$ $92,$ $93,$ and $97

79, 84, 86, 92, 93, 97

Highest possible score obtainable in a test = 100

Hence to calculate the highest possible score she could still attain;

We assume she obtained a score of 100 in all remaining 3 tests

Then the data becomes :

79, 84, 86, 92, 93, 97, 100, 100, 100

Median of the dataset:

Q2 = 1/2(n + 1)th term

n = sample size = 9

Q2 = 1/2(9 + 1)th term

Q2 = 1/2(10)th term

Q2 = 5th term

Q2 = 93

Answer:

1) simplified would be 4m^5

2) simplified would be 2m

3) would be 8/r

The error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.

The number that is rounded off is:

x = 9.8

9.8 can be rounded off for 9.75 to 9.84

So, this means that:

9.75 ≤ x

or 9.84 ≥ x

So, the error interval becomes:

9.75 ≤ x ≤ 9.84

Therefore, we get that, the error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.

Answer: 3:2

Step-by-step explanation:

the base ratio of unused tape to used tape is 24:16.

then we have to simplify,

both 16 and 24 can be divided by eight,

24 divided by eight is 3

16 divided by eight is 2

therefore, our simlpified ratio is 3:2

Answer:

Step-by-step explanation:

the distance around the figure--we need to find the perimeter

we have rectangle that has the side, 8 and 15

P(r)=2(8)+2(15)=16+30=46

we also have half of the circle with the diameter =8 and r=4

Circumference =2*3.14*r

C=2*3.14*4=25.12

we need just half of the circle 25.12/2=12.56

P figure=46+12.56=58.56

Area= rectangle=l*w=8*15=120

Area(circle)=3.14*r^2=3.14*16=50.24

half circle 50.24/2=25.12

Area figure=120+25.12=145.12

Answer:

$48

Step-by-step explanation:

so since the column on the right says n is 4 (next to yellow box), you would substitute 4 for n.

c=12n

c=12(4)

c=48

Answer:

B is your answer

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Option B:

3x = 15

x = 15 / 3

x = 5

[tex]y = a {(x - h)}^{2} + k[/tex]

where a-term determines the shape of graph.

h-term determines the change of graph for x-axis.

k-term determines the change of graph for y-axis.

Vertex of the graph is at (h,k).

[tex]y = a {(x - 7)}^{2} + 2[/tex]

We need to find the value of a-term. We have the given root which we can substitute in the equation.

Also the roots are on x-axis, meaning that the y-value for roots must be 0.

[tex]0 =a {(5 - 7)}^{2} + 2 \\ 0 =a {( - 2)} ^{2} + 2 \\ 0 = 4a + 2[/tex]

[tex]4a + 2 = 0 \\ 4a = - 2 \\ a = \frac{ - 2}{4} \\ a = - \frac{1}{2} [/tex]

Therefore the value of a is - 1/2. Rewrite the equation as we get the answer.

[tex] \large \boxed{y = - \frac{1}{2} {(x - 7)}^{2} + 2}[/tex]
