Anna shops in an international store. A t-shirt with a tag price P420 is marked “save 20%.” How much will Anna have to pay for the t-shirt if she were to buy it?

Answer:

yes: each input has only one output

Answer: 160 children and 174 adults

Step-by-step explanation:

Let x represent the children and y represent the adults.

Create two equations:

x+y=334

1.50x+2y=588

Subtract 1.50x from the equation, then divide by 2:

y=294 - 0.75x

Plug it into the first equation then solve.

x+294-0.75x=334

x=160

Subtract 160 from 334 to get y:

y=174

Step-by-step explanation:

Ericsson is claimed to increase the likelihood of a baby girl ;

Given the alternative hypothesis to buttress this claim :

HA : p>0.5

In other to establish the success of Ericsson's claim, then there must be significant evidence to reject the Null hypothesis ; hence adopt the alternative.

To Do this, we need a very small Pvalue ; such that it will be lesser than the α - value in other to reject the Null and adopt the alternative.

Recall ;

Pvalue < α ; We reject the Null

Therefore, from the options, we choose the smallest Pvalue as we want the Pvalue to be as small as possible.

Equivalent fractions are fractions that represent the same value or amount, despite having different numerators and denominators.

In other words, equivalent fractions have the same ratio or proportion, but may be written in different forms.

For example, the fractions 1/2 and 2/4 are equivalent fractions because they represent the same amount, which is half of a whole.

Also, 3/5 and 6/10 are equivalent fractions because they both represent three-fifths or 60% of a whole.

Answer:

Step-by-step explanation:

a. The vertex is (1, -9).  False.  The vertex is (-1, -9).

b. The graph opens upward.  True.  That coefficient '6' is positive.

c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units.  False.  It's DOWN 9 units.

d. The graph is steeper than the graph of f(x) = x^2.  True.  The given function increases 6 times faster than does x^2.

e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.

Let's put f(x) = 6(x + 1)^2 -9 into standard form.  Expanding the first term, we get f(x) = 6(x^2 + 2x + 1) - 9, or f(x) = 6x^2 + 12x + 6 - 9.  YES, TRUE

Answer:

Find the "zeros" and plug in points

Step-by-step explanation:

You can tell this graph is a parabola.

We can find the "zeros" of the graph to help us.

Find the zeros:

2x-1=0

2x=1

x=0.5

2x-5=0

2x=5

x=2.5

We can substitute values into f(x)=(2x-1)(2x-5) to graph.

You should get (1.5,-4) to be the vertex.

Answer:

The missing numbers are 12 and 39 respectively

Step-by-step explanation:

From the table, we can see that the ratio of the left column to the right is 3/5

So at any point in time, the values on a particular row of the table must conform

to this ratio

In other light, we have to multiply what we have on the left by 5/3 to get what’s on the right

and we have to multiply what we have on the right by 3/5 to get what’s on the left

We have this as follows;

20 * 3/5 = 12

and;

65 * 3/5 = 39

Answer:

x = 50/7, or x = 7 1/7

Step-by-step explanation:

Create and solve an equation of ratios, as follows:

5      x

--- = ----

7     10

Cross-multiplying, we get:  7x = 50, or x = 50/7, or x = 7 1/7

Answer:

x² - 3x + 0.25 = 0

Step-by-step explanation:

Given a root x = a then the corresponding factor is (x - a)

Given roots x = 1.5 + [tex]\sqrt{2}[/tex] and x = 1.5 - [tex]\sqrt{2}[/tex] then the factors are

(x - (1.5 + [tex]\sqrt{2}[/tex] ) ) and (x - (1.5 - [tex]\sqrt{2}[/tex] ) ) , that is

(x - 1.5 - [tex]\sqrt{2}[/tex] ) and (x - 1.5 + [tex]\sqrt{2}[/tex] )

The equation is then the product of the factors

(x - 1.5 - [tex]\sqrt{2}[/tex] )(x - 1.5 + [tex]\sqrt{2}[/tex] ) = 0 ← expand factors using FOIL

(x - 1.5)² - ([tex]\sqrt{2}[/tex] )² = 0

x² - 3x + 2.25 - 2 = 0

x² - 3x + 0.25 = 0

Option B

Answer:

[tex]\begin{cases} \sf a_1=-6 \\ \sf a_n=a_{n-1}+4 \end{cases}[/tex]

Step-by-step explanation:

Given:

From inspection of the given terms, it is evident that there is a common difference between consecutive terms.  Therefore, this is an arithmetic sequence.

A recursive formula for an arithmetic sequence allows you to find the nth term of the sequence provided you know the value of the previous term in the sequence.

From inspection of the sequence, we can see that each term is found by adding 4 to the previous term.  Therefore, the recursive formula is:

[tex]\sf a_n=a_{n-1}+4[/tex]

A recursive rule comprises the recursive formula together with the 1st term a₁.  To find the 1st term, keep subtracting 4 from each term:

[tex]\begin{aligned} \sf a_3 & = \sf a_4 - 4\\ & = \sf 6 - 4\\ & = \sf 2\end{aligned}[/tex]

[tex]\begin{aligned} \sf a_2 & = \sf a_3 - 4\\ & = \sf 2-4 \\ & = \sf -2\end{aligned}[/tex]

[tex]\begin{aligned} \sf a_1 & = \sf a_2 - 4\\ & = \sf -2-4 \\ & = \sf -6\end{aligned}[/tex]

Therefore, the recursive rule that can be used to find the nth term of the sequence is:

[tex]\begin{cases} \sf a_1=-6 \\ \sf a_n=a_{n-1}+4 \end{cases}[/tex]

Answer: -17x-1

Answer:

-17x-1

Step-by-step explanation:

Answer:

a. 13 , b. = 4 , c. 2.2

Step-by-step explanation:

Given : a xx b = ab + b - a

So, no.1 xx no.2 = Product no.1 x no.2 + no.1 - no.2

As evident 3 xx 7 = (3 x 7) + 3 - 7 → 3 xx 7 = 21 + 3 - 7 = 17

Hence, 5 xx 2 = (5 x 2) + 5 - 2 → 5 xx 2 = 10 + 5 - 2 = 13

3 xx 1/2 = 3 (1/2) + 3 - 1/2 = 1.5 + 3 - 0.5 = 4

x xx 5 = 8

x xx 5 = 5x + x - 5

6x - 5 = 8

6x = 13

Answer:

B)

Step-by-step explanation:

let 's' = # shirts they can buy

8s + 45 ≤ 325

8s ≤ 280

s ≤ 35

they cannot purchase more than 35 shirts

first set up the equation:

let t = number of t-shirts

8t + 45 [tex]\leq[/tex] 325

solve for t:

subtract 45 from both sides

8t [tex]\leq[/tex] 280

divide both sides by 8

t  [tex]\leq[/tex] 35

looking at the number line:

when placing this onto the numberline, there should be a close circle at 35 and the arrow should be going towards 0 to show that it is less than or equal to 35

answer: B

Answer:

H = 42

Step-by-step explanation:

18 ÷ 108 = [tex]\frac{1}{6}[/tex]

7 ÷ [tex]\frac{1}{6}[/tex] = 42

You can check to make sure your answer is right by entering your proportions into a calculator. For example, [tex]\frac{42}{108}=0.38888888888...[/tex] and [tex]\frac{7}{18}[/tex] also equals [tex]0.38888888888...[/tex] so since they match, we know it is correct.

Answer:

180000

Step-by-step explanation:

Solve

Given: Both Raised $240,000, Blin raised $60,000 more than Alex

To find: How much money Blin raised

Firstly, since two people raised that amount, divide the amount by 2 of them

240,000 ÷ 2 = 120,000

Nextly, subtract 60,000 from Alex's share; because Brin has more so Alex has less, less means subtract.

120,000 - 60,000 = 60,000

Now, Add that amount to Brin's share; again, Brin has more so Alex has less, less means subtract.

60000 + 120,000 = 180,000

Therefore, Brin raised $180,000

Confirm: 180,000 + 60,000 = 240,000

(For your information, Alex has $60,000)

Step-by-step explanation:

The question is incomplete, as there are no options to select from.

However, a general explanation is as follows.

Given

[tex]2\ cups = 1\ pint[/tex]

Required

Is [tex]c = 2p[/tex] a correct expression?

Let

[tex]c = cups[/tex]

[tex]p = pint[/tex]

So:

[tex]2\ cups = 1\ pint[/tex]

becomes

[tex]2 * c = 1 * p[/tex]

[tex]2c = p[/tex]

Divide both sides by 2

[tex]c =\frac{1}{2}p[/tex]

Hence:

[tex]c = 2p[/tex] is incorrect
