The ratio of right-handed students to left-handed students is 18:4.

Answer:

169 cm^2

Step-by-step explanation:

Right surface (rectangle)

A = LW = 7 cm * 5 cm = 35 cm^2

Left surface (hidden rectangle)

A = LW = 7 cm * 5 cm = 35 cm^2

Bottom surface (hidden rectangle)

A = LW = 9 cm * 5 cm = 45 cm^2

Front face = back face = 2 * triangle

A = 2 * bh/2 = 2 * 9 cm * 6 cm/2 = 54 cm^2

total surface area = 35 cm^2 + 35 cm^2 + 45 cm^2 + 54 cm^2 = 169 cm^2

Answer:

the answer is 1 and 7

Step-by-step explanation:

4 times 2 is 8 -7 =1

6 times 2 =12 -5 =7

Answer:

First problem equals 1 and second problem equals 7.

First multiply 4x2 to get 8, then subtract it by 7.  That would leave you with 1.

Now, 6x2 would be 12 minus 5 which would equal 7.

Answer:

4

Step-by-step explanation:

11 - 7 = 4

The required length of JK is 4 units.

It is required to find the length of JK.

Length is defined as the measurement or extent of something from end to end.  The greater of two or the greatest of three dimensions of an object. It can be measured in different units like centimeters, inches, meters, etc.

Given:

Point K on the  line segment  JL.

KL = 7

JL = 11

As per segment addition postulate

JL = JK + KL

Substituting values, to find the value JK we get,

11 = JK + 7

JK = 11 - 7

JK = 4

Therefore, the required length of JK is 4 units.

Answer:

B

Step-by-step explanation:

when you flip across the y axis you change the signs of the x coordinate but not the y coordinate.

Answer:

x = 0.2

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

3.5 + 1.2(6.3 - 7x) = 9.38

Step 2: Parenthesis (distribute)

3.5 + 7.56 - 8.4x = 9.38

Step 3: Combine like terms (constants)

11.06 - 8.4x = 9.38

Step 4: Subtract 11.06 on both sides

-8.4x = -1.68

Step 5: Divide both sides by -8.4

x = 0.2

Answer: E

Step-by-step explanation:

(-3^2) multiply -3 by itself to get -9

Now you have -2 x -9 or -2(-9)

Remember that multiplying a negative by a negative will get you a positive because the two negative signs are canceled out.

So -2(-9) gives you 18

Answer: The real numbers include natural numbers or counting numbers, whole numbers, integers, rational numbers (fractions and repeating or terminating decimals), and irrational numbers. The set of real numbers is all the numbers that have a location on the number line. Integers …, −3, −2, −1, 0, 1, 2, 3, and so on. All whole numbers are integers, so since 0 is a whole number, 0 is also an integer.

Answer: Wrong

Step-by-step explanation:

Continuous means every value is included. Since fractions of people do not exist, it cannot be continuous.

Wen is wrong.

It is given that ; according to Wen a function is continuous because number of people are unlimited.

We have to tell that whether Wen is right or wrong ?

What is a continuous function ?

A continuous function, is a function whose graph is continuous without any breaks or jumps.

We know that ;

A continuous function in calculus is continuous at a point x = a ; if the curve of the function does NOT break at the point x = a.

We can also say that , continuous means every value is included.

Since fractions of people don't exist, i.e., unlimited , So, it cannot be continuous.

Answer:

[tex]\huge\boxed{\sf Volume = 384 \ cm^3}[/tex]

Step-by-step explanation:

Slant Height = 10 cm

Base Edge = 12 cm

Finding the Height using Pythagorean Theorem:

[tex]\sf c^2 = a^2 + b^2 \\\\Where \ c = 10\ cm , b = 6\ cm [Half of 12] \ and \ a \ is \ height\\\\10^2 = a^2 + 6^2\\\\100=a^2 +36\\\\100-36 = a^2\\\\64 = a^2\\\\Taking \ sqrt \ on \ both \ sides\\\\Height= 8 \ cm[/tex]

[tex]\rule[225]{225}{2}[/tex]

Now, Finding the volume:

[tex]\sf Volume = a^2 \frac{h}{3}\\\\ Where \ a \ is base \ edge \ and \ h \ is \ height\\\\Volume = (12)^2 \frac{8}{3} \\\\Volume = 144 \frac{8}{3} \\\\Volume = 48*8\\\\\bold{Volume = 384 \ c m^3}[/tex]

Answer:

19/6

Step-by-step explanation:

1 2/3= 5/3 = 10/6

1.5= 3/2= 9/6

10/6+9/6=19/6

To make the equation go through (0,-4) the new equation would be 9x + 5y = 20. We needed to change it from subtracting to adding so the direction of the line would go from going down to up too up to down. In slope-intercept form the original equation would be found by the following.

9x - 6y = 20

-6y = 20 - 9x

y = -20/6 - (-9/6x)

y = 9/6x - 20/6

y = 3/2x - 10/3

To make the perpendicular line, take the slope and apply the opposite and reciprocal.

y = -2/3x - 10/3

Best of Luck!

Answer:

Step-by-step explanation:

We can form a table for the relation between muffins sold and days of the week given in the graph.

Days                    Muffins sold

Monday                       5

Tuesday                      6

Wednesday                 5

Thursday                     8

Friday                          10

Saturday                      13

Sunday                        15

This data reflects the sales of muffins are increasing continuously in the given week.

Therefore, number of muffins sold are directly proportional to the number of days of the week.
