3/10

Step-by-step explanation:

60% is the same as 60/100

90% is the same as 90/100

90-60=30

30/100

30/100 is divided by 10 on each side to simplify it to 3/10

If it starts at 7 and there are 8 lines going to the number 8, then each line represents 1/8 of the distance between 7 and 8, or 1/8 of a unit. If it stops at the third line, then it has traveled 3/8 of a unit. Therefore, the number it represents is 7 + 3/8, or 7.375.

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

No

Step-by-step explanation:

Two positive integers can never make negative integers because they are all greater than 0. For example, numbers above 10 like 11 and 13 can never add up to 10. It is the same with negative numbers

Step-by-step explanation:

1. He Saves 10% From 15$.

It Means 10% Of 15$ Is 1.5$

Which Is 15 Dimes.

The Answer Is 15$ - 1.5$ = 13.5$

2. He Saves 25%.

As 6$ Of 24$ Is

25% Because

10% Is 2.4$. Then, 5% Of 24$ Is 1.2$

So, 2.4$ × 2 + 1.2$

It's 6$.

Solve step by step : x=12 because it said the height is 12.

Inside, x-6, so therefor it would really be, 12-6. Which we know would be 6.

Perimeter : 60

now we know the inside is 6. The outside height is 12. 6+12=18. So the width would be 18. 18+12+18+12 = 30+30 = 60.

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer:

16/63

Step-by-step explanation:

Given problem,

→ (8/9) × (2/7)

Let's solve the problem,

→ (8/9) × (2/7)

→ (8 × 2)/(9 × 7)

→ 16/63

Hence, answer is 16/63.

Answer:

\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)

See attachment for the graph of the equation.

Step-by-step explanation:

Given equation:

\(y=\dfrac{1}{3}x\)

To complete the table, find the corresponding values of y by substituting each given value of x into the equation.

\(x=6 \implies y=\dfrac{1}{3}(6)=\dfrac{6}{3}=2\)

\(x=12 \implies y=\dfrac{1}{3}(12)=\dfrac{12}{3}=4\)

\(x=18 \implies y=\dfrac{1}{3}(18)=\dfrac{18}{3}=6\)

Therefore the completed table is:

\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Ruth’s new floor cost $432.

The cost can be calculated as follows.

First, calculate the area of dining room. Use the formula of rectangle area (width x length)

Area = width x length

= 6 yd x 9 yd

= 54 sq yd

Second, calculate the total cost.

Cost = 54 sq yd x $ 8 per sq yd

= $ 432

Hence it cost $ 432 to install the new wood floor.

Answer:

$432

Step-by-step explanation:

1. Find the area of the dining room. The equation for finding the area is Length x Width = Area, so, 9x6=54 square yards.

2. Then, since each square yard is $8.00, multiply 54 and 8 to get $432.

Answer:

1.6 < 1.622

Step-by-step explanation:

1.6 is equal to 1.600

Answer: 1,600 ml

Step-by-step explanation:

You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).

2,800 ml - 1,200 ml = 1,600 ml

I hope this helps :)

Answer: 1,600 mL

Step-by-step explanation:

1. convert the 1,200 mL to L, which is 1.2 L.

2. Subtract that value from 2.8 L, equaling 1.6 L

3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

Answer:

\(a = 2; b = 1\ and\ c = -1\)

Step-by-step explanation:

Given

\((x+4)(ax^2+bx+c)=2x^3+9x^2+3x-4\)

Required

\(Find\ a,b,c\)

\((x+4)(ax^2+bx+c)=2x^3+9x^2+3x-4\)

Open Bracket

\((x)(ax^2+bx+c)+(4)(ax^2+bx+c)=2x^3+9x^2+3x-4\)

\(ax^3+bx^2+cx+4ax^2+4bx+4c=2x^3+9x^2+3x-4\)

Collect like terms

\(ax^3+bx^2+4ax^2+cx+4bx+4c=2x^3+9x^2+3x-4\)

By comparing coefficients; we have

\(ax^3=2x^3\\bx^2+4ax^2=9x^2\\cx+4bx=3x\\4c=-4\)

Remove all traces of x from both sides

\(a=2\\b+4a=9\\c+4b=3\\4c=-4\)

From the first equation;

\(a = 2\)

From the last equation

\(4c = -4\)

Divide both sides by 4

\(\frac{4c}{4} = \frac{-4}{4}\)

\(c = \frac{-4}{4}\)

\(c = -1\)

Substitute -1 for c in the third equation

\(c+4b=3\)

\(-1 + 4b = 3\)

Add 1 to both sides

\(1-1 + 4b = 3+1\)

\(4b = 4\)

Divide both sides by 4

\(\frac{4b}{4} = \frac{4}{4}\)

\(b = \frac{4}{4}\)

\(b = 1\)

Substitute 2 for a in the second equation [To confirm the value of b]

\(b+4(2)=9\)

\(b + 8 = 9\)

Subtract 8 from both sides

\(b + 8 - 8 = 9 - 8\)

\(b = 1\)

Hence;

\(a = 2; b = 1\ and\ c = -1\)

yes
