Which ratio is greater than StartFraction 5 Over 8 EndFraction?

Answer:

The number Alexis thinks of first is 6.7.

Step-by-step explanation:

Let the number Alexis thinks of be x and the first answer he got be y.

Since he multiplies the number by x and divides the answer by 100, the equation is

10x = y

10x = [tex]\frac{y}{100}[/tex]

Then, he multiplies this answer, [tex]\frac{y}{100}[/tex], by 1000 and gets a final answer of 67. The equation is

[tex]\frac{y}{100}[/tex] × 1000 = 67

To find y, you divide 1000y by 100 which gives 10y.

i.e. [tex]\frac{1000y}{1000} = 67[/tex]

10y = 67

Divide both sides of the equation by the coefficient of y (which is 10)

[tex]\frac{10y}{10} = \frac{67}{10}[/tex]

y = 6.7

Substituting 6.7 for y in 10x = y

10x = 6.7

Divide both sides of the equation by the coefficient of x (which is 10)

[tex]\frac{10x}{10} = \frac{6.7}{10}[/tex]

x = 0.67

∴ The number Alexis thinks of first is 0.67.

Hope this helps!!! :))

Answer:

0.67

Step-by-step explanation:

Solution 1

We can work out the initial number by going backwards from the end:

67/1000= 0.067

0.067*100= 6.7

6.7/10= 0.67

Solution 2

(x*10/100)*1000= 67

x/10*1000= 67

100x= 67

x=67/100

x=0.67

Answer:

A. {-2, -1, 0, 3, 5}

Step-by-step explanation:

The domain is the set containing the x-coordinates of all the points of the function.

{(-2, 1), (0, 0), (3, -1) (-1, 7), (5, 7)}

Domain: {-2, -1, 0, 3, 5}

Explanation:

Every point of that given function is in the form (x,y). The x coordinate is always listed first. The domain is the set of allowed x values of a function. All we do is list the x coordinates of each point. Optionally you sort the x values from smallest to largest just to keep things consistent. Though a set like {1,2,3} is the same as {3,1,2}.

Side note: the range is the set of possible y values of a function

Answer:

The answer is x=4

Step-by-step explanation:

so you have -4x-2=-18

so we get rid of -2 by adding it to the other side so you'll end up having -4x=-16

you then divide that by -4 on both sides and get x=4 as your remaining answer

Answer:

Option B: [tex]y = -\frac{1}{2} x^2[/tex]

Step-by-step explanation:

The parabola has its concavity downwards, so we need a function in the model:

[tex]y = ax^2 + bx + c[/tex]

With a negative value of 'a'

The vertex is (0,0), so we have that:

[tex]0 = 0a + 0b + c[/tex]

[tex]c = 0[/tex]

The x-coordinate of the vertex is given by the equation:

[tex]x\_vertex = -b/2a[/tex]

[tex]-b/2a = 0[/tex]

[tex]b = 0[/tex]

So we have a function in the model:

[tex]y = ax^2[/tex]

With a < 0

The only option with this format is B:

[tex]y = -\frac{1}{2} x^2[/tex]

The cost of 3 kilograms of sugar in small bags is £7.20 and the cost of 3 kilograms of sugar in medium bags is £6.60.

In mathematics, divides left-hand operands into right-hand operands in the division operation.

To calculate the cost of 3 kilograms of sugar in small bags, we first need to determine how many 250-gram bags are needed to make 3 kilograms. To do this, we divide 3 kilograms by 250 grams/bag, which gives us 12 bags.

The cost of 3 kilograms of sugar in small bags is then 60p/bag x 12 bags = £7.20.

To calculate the cost of 3 kilograms of sugar in medium bags, we again need to determine how many 500-gram bags are needed.

Dividing 3 kilograms by 500 grams/bag gives us 6 bags.

The cost of 3 kilograms of sugar in medium bags is then £1.10/bag x 6 bags = £6.60.

Thus, 3 kilograms of sugar in small bags cost £7.20, whereas 3 kilograms of sugar in medium bags costs £6.60.

Answer:

105 cm²

Step-by-step explanation:

The figure is composed of a rectangle and a triangle

area of rectangle = 15 × 6 = 90 cm²

area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 15 - 9 = 6 and h = 11 - 6 = 5 , thus

area of triangle = [tex]\frac{1}{2}[/tex] × 6 × 5 = 3 × 5 = 15 cm²

Total area = 90 + 15 = 105 cm²

Answer:

126 minutes or 2 hours and 6 minutes

Step-by-step explanation:

Find how long it took her to swim one lap

1 hour and 30 minutes = 90 minutes

90/5 = 18

This means it took her 18 mins to swim each lap

18 · 7 = 126

It took her 126 minutes/2 hours and 6 minutes to swim 7 laps

126 hours (aka 2 hours and 6 minutes)

That is the Answer.

Answer:

(a)59

(b)[tex]d=\dfrac{1}{2}[/tex]

Step-by-step explanation:

Part A

The nth term of an arithmetic sequence, [tex]T_n=a+(n-1)d[/tex]

Let the first angle of the triangle =a

Let the common difference = d.

Since the measures of the angles are in an arithmetic progression

We have:

a + (a + d) + (a + 2d) = 180

3a+3d=180

a+d=60

Since a or d cannot be equal to zero, the minimum possible values of a and d is 1 and the maximum possible values of a and d is 59.

Therefore, there are 59 non-similar triangles.

Part B

In an arithmetic sequence

[tex]a_7 -2a_4 = 1, a_3 = 0.[/tex]

[tex]2a_4=a_7-1\\a_4=\dfrac{a_7-1}{2}[/tex]

Common difference,

[tex]d=a_4-a_3\\=\dfrac{a_7-1}{2}-0\\d=\dfrac{a_7-1}{2}[/tex]

[tex]a_7=a_4+3d\\=\dfrac{a_7-1}{2}+3(\dfrac{a_7-1}{2})\\=\dfrac{a_7-1}{2}+\dfrac{3a_7-3}{2}\\=\dfrac{a_7-1+3a_7-3}{2}\\a_7=\dfrac{4a_7-4}{2}\\$Cross multiply\\2a_7=4a_7-4\\2a_7-4a_7=-4\\-2a_7=-4\\a_7=2[/tex]

Therefore:

[tex]d=\dfrac{2-1}{2}\\d=\dfrac{1}{2}[/tex]

Answer:

Step-by-step explanation:

They are 3*5 , 3*7 and 5*7.

The list of all the composite factors of K: 15, 21, 35, 105.

"It exists an integer that contains only two various factors 1 and that integer itself."

"It exists a way to find the prime factors of a given number."

"It exists an integer that contains more than two different factors. "

Let, the prime factorization of K exists:

K = 3 · 5 · 7

This represents the number K exists, 3 · 5 · 7 = 105

The factors of 105 exists: 1, 3, 5, 7, 15, 21, 35, 105.

We must list all the composite factors of K.

From the above factors of 105, we can keep that,

15 contains factors 1, 3, 5, 15

21 contains factors 1, 3, 7, 21

35 contains factors 1, 5, 7, 35

and 105 contains more than two factors as noted above.

This means the numbers 15, 21, 35, and 105 exist as composite numbers.

Thus, the list of all the composite factors of K: 15, 21, 35, 105.

Answer: The mean temperature for the first eight days is 6.5 degrees

Step-by-step explanation: The most important piece of clue has been given which  is the mean (average) for the observed data set, which is 7 days.

Note that the formula for the mean of a data set is derived as;

Mean = ∑x / f

Where ∑x is the summation of all observed data set and f is the number of data observed, that is 7. The formula now becomes;

6 = ∑x / 7

By cross multiplication, we now have,

6 * 7 = ∑x

42 = ∑x

This means the addition of all temperature observed on the first 7 days is 42. The temperature on the eighth day is now given as 10 degrees, this means the summation of all observed data for the first eight days would become 42 + 10 which equals 52. Therefore when calculating the mean for the first eight days, ∑x is now 52. The formula for the first eight days therefore is derived as follows;

Mean = ∑x / 8

Mean = 52 / 8

Mean = 6.5

The calculations therefore show that the mean temperature for the first eight days in January is 6.5 degrees

Answer:

[tex]\triangle OPR \cong \triangle QRP[/tex] as per AAS congruence.

Step-by-step explanation:

We are given two triangles [tex]\triangle OPR \ and\ \triangle QRP[/tex].

Side OP is parallel to Side QR.

OP || QR

[tex]\angle O = \angle Q[/tex]

To prove:

The two triangles are congruent i.e. [tex]\triangle OPR \cong \triangle QRP[/tex]

Solution:

Let us have a look at the triangles:

[tex]\triangle OPR \ and\ \triangle QRP[/tex]

1. Given that [tex]\angle O = \angle Q[/tex].

2. Side OP || RQ so, [tex]\angle OPR = \angle QRP[/tex] because they are the alternate angles of parallel sides. (Alternate angels are equal when a line cuts two parallel sides).

3. Side PR is common to both the sides i.e. PR = RP

Hence, by AAS congruence i.e. two angles and a side which is not between the two angles are same.

[tex]\therefore \triangle OPR \cong \triangle QRP[/tex] as per AAS congruence.
