What is the value of Z ?

Answer:

Step-by-step explanation:

surface area of cuboid=2(lb+bh+hl_

=2(7*4+4*5+5*7)

=2(28+20+35)

=2*83

=166 mm^2

Given figure is cuboid so use surface area of cuboid formula.

Answer:

36

Step-by-step explanation:

All angles in the triangle will equal to 180

Angle A = 180-98-46

A=36

Answer:

A=36

Step-by-step explanation:

A=180-(b+c)

=180-144

=36

since the sum of the triangle angles is 180

Answer:

Two quantities can be compared by a ratio. As a fraction in the simplest form, a typical manner of expressing a ratio. If you compare the two numbers with distinct measuring units, this type of ratio is known as a rate. A rate is unit rate when it is 1. A rate is unit rate.

Step-by-step explanation:

Answer:

You can use a ratio to compare things for example you can compare the number of people in class, there are 6 boys and 8 girls so you will compare them like this : 6:8.

There are various ways to do this : 6/8 as a fraction, 6:8 or in words 6 to 8. You have to make sure to write it in the correct order or you will for sure not get the point.

Answer:

[tex] - 13 = 5 + a \\ a = - 13 - 5 \\ a = - 18[/tex]

Answer: a=-18

Step-by-step explanation:

Subtract 5 from both sides

Answer:

C

Step-by-step explanation:

Write the expression out

factor it

[tex](\frac{(x+1)(x-1)}{6x})(\frac{3x(x)}{x(x+1)})[/tex]

cancel out all everything that is the same and appears on both the top and the bottom

Cancel out:

(x+1)

(x)

(x)

leaves you with

[tex]\frac{3(x-1)}{6}[/tex]

3 goes into 6 '2' times so the 3 in the numerator cancels out too. The 6 in the denominator turns into a 2

This leaves you with the final answer of

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

Answer:

C

Step-by-step explanation:

after factoring them

they become:

[tex]\frac{(x+1)(x-1)3x^2}{6x^2(x+1)}[/tex]

after dividing the numerator and denominator by 3x^2(x+1)

it becomes (x-1)/2

Answer:

Slope: [tex]\frac{7}{5}[/tex]

Y-intercept: -5

Step-by-step explanation:

If the equation of the line is not given but is graphed we can do in this way:

First, it's very simple to find the y-intercept: is -5 as you can see (the line touch the points -5 in the y line).

You know that the slope can be find by having two points (now we have the A(0; -5) (the y-intercept point).

As you can see, the line touch also the B(5; 2) perfectly.

Now we simply use this formula for find the slope:

[tex]s=\frac{yB-yA}{xB-xA}[/tex]

Let's substitute the value:

[tex]slope=\frac{2+5}{0+5}[/tex]

[tex]slope = \frac{7}{5}[/tex]

Answer:

Slope: 7/5

Y-intercept: -5

Answer:

x = 37

Step-by-step explanation:

The angle with a measure of 74 degrees and the angle labeled "2x" are vertical angles

Vertical angles are congruent ( equal to each other )

Hence, 74 = 2x

             ^(note that we just created an equation that we can use to solve for x)

Now we solve for x

74 = 2x

step 1 divide each side by 2

74 / 2= 37

2x / 2 = x

we're left with x = 37

Answer:

7^2 =49

Step-by-step explanation:

Exponents represent a number and how many times you multiply it by itself. So 5^2 is 5*5 or 4^3 is 4*4*4. So 7^2 is 7*7, which is 49!

Answer:

Step-by-step explanation:

I only know the answer to #1, 2 degrees is warmer because -5 degrees Celsius is equal to 23 degrees fehrinheit, and 2 degrees Celsius is equal to 35.6 degrees fehrinheit, therefore, 2 degrees Celsius is warmer.

Answer:

A. C = 43.96

Step-by-step explanation:

Circumference = Diameter * pi

Your diameter in this problem (given by the picture) = 14 inches.

If we plug this into the formula:

C = 14 * 3.14 = 43.96

There is a problem with your question, however, because the length we have found is in inches, while all of your options are in centimeters. However, converting the correct inches answers into centimeters is not an answer choice.

Answer:

Assuming you want them to weigh the same the answer would be 3 grams

Step-by-step explanation:

Because... 6 × 3 = 18 3 × 4 = 12

18 + 12 = 30

6 × 4 = 24 3 × 2 = 6 24 + 6 = 30 therefore

squares = 3

Hope this helps not sure if I am right.

Answer: 3 grames

3 because half of 6 is 3 that’s why and that it is balance so I know they are equal

Answer:

LMK is 30  

Step-by-step explanation:

inside the triangle, the LMN is the equation 3x=90degrees

under the KN is 4x

on the left is 150dgrees = 5x

3x+4x+5x=360

add the x's together

12x=360

divide

x=30

LMK= 150-90/2=60/2=30

Step-by-step explanation:

The required scenario in the below solution part would lead to the given equation 2r + 15 = 25. The correct answer would be option (C).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.

The equation is given in the question, as follows:

2r + 15 = 25

Let r be items you can buy at the concession stand.

You are going to the movies with some friends. You have $25 to spend. The movie costs $15 and each item at the concession stand costs $2. This equation shows how many items you can buy at the concession stand.

Thus, the required scenario in the above solution part would lead to the given equation.
