Someone please help me answer at least one of these problems it’s really hard and it’s due by tomorrow and I really don’t get it someone helppp

yellow car = x

 white cars = 9x ( 9 times as many white cars)

9x +x = 40

10x = 40

x = 40/10 =4

4 yellow cars

9*4 = 36 white cars

you are right, when you see a number like 7√2

 you would multiply 7 by √2

which = 7 x 1.41 = 9.87

Answer:

C

Step-by-step explanation:

The inverse of a statement "If p then q" is the statement "if ¬p then ¬q". In our case p is "x=2" and q is "x+3=5". Moreover, the negations of p and q are "[tex]x \neq 2[/tex]" and [tex]x+3 \neq 5[/tex] respectively. Then, the inverse of the original statement is

[tex]\text{if} \quad x\neq 2 \quad \text{then} \quad x+3 \neq 5[/tex]

To solve the equation r + (-6) = -10, since -6 is being added to r, we need to subtract -6 from both sides of the equation.

It's important to understand that minus a negative means the same thing as plus a positive so we're really adding 6.

On the left side of the equation, the -6 and +6 cancel out and we have r. On the right side of the equation, -10 + 6 is -4.

So we have r = -4 which is the solution to our equation.

In scientific notation, the coefficient is a number from 1 to 10 multiplied by a power of 10, which represents the number of decimal places moved to convert a number to this format.

The first factor in an expression in scientific notation is the coefficient, which must be a number equal to or greater than 1 and less than 10. The coefficient is then multiplied by a power of 10 to represent the original number accurately.

For example, to write the number 79,345 in scientific notation, one would express it as 7.9345 × 104, because we have moved the decimal place to make 79,345 into 7.9345 while recording that we have moved the decimal place four positions to the right, hence the power of 10 being 4.

Answer: The slope of the line is [tex]-\frac{1}{3}[/tex].

Explanation:

From the given graph it is noticed that the line passing through many points.

The coordinates of three given points are (-6,6), (0,4) and (6,2).

If a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], the slope of the lie is defined by,

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The line passing through two points (0,4) and (6,2). So the slope of the line is,

[tex]m=\frac{2-4}{6-0}[/tex]

[tex]m=\frac{-2}{6}[/tex]

[tex]m=-\frac{1}{3}[/tex]

Therefore, the slope of the line is [tex]-\frac{1}{3}[/tex].

Which of the following is not a way to represent the solution of the inequality 2(x + 1)  alt= 20?

Step-by-step explanation:

To determine the cost of 4 erasers, set up a proportion using the given information.

To determine the cost of 4 erasers, we can set up a proportion using the given information. We know that 3 erasers cost $4.41, so we can write the equation:

3 erasers / $4.41 = 4 erasers / x

To solve for x, we can cross-multiply:

3 * x = 4 * $4.41

x = (4 * $4.41) / 3

Calculating this, we find that the cost of 4 erasers is $5.88. So, the equation that will help determine the cost of 4 erasers is 3 erasers / $4.41 = 4 erasers / $5.88.

The correct equation that represents this relationship and would help determine the cost of 4 erasers is:[tex]\[ \frac{4}{x} = \frac{3}{4.41} \][/tex]

The correct option is (A).

The image shows multiple choice options for equations that could be used to determine the cost of 4 erasers given that 3 erasers cost $4.41.

To find the cost of 4 erasers, we would want to set up a proportion where the number of erasers is directly proportional to the total cost. Given that 3 erasers cost $4.41, we can write this relationship as:

[tex]\[ \frac{\text{Number of erasers}}{\text{Cost}} = \frac{3}{4.41} \][/tex]

We want to find the cost for 4 erasers, so we can set up an equation with [tex]\( x \)[/tex] representing the unknown cost for 4 erasers:

[tex]\[ \frac{4}{x} = \frac{3}{4.41} \][/tex]

This equation can be solved to find \( x \), the cost for 4 erasers. We can cross multiply to solve for \( x \):

[tex]\[ 3 \times x = 4 \times 4.41 \][/tex]

[tex]\[ x = \frac{4 \times 4.41}{3} \][/tex]

Let's solve for[tex]\( x \)[/tex] to find the cost of 4 erasers.

The cost for 4 erasers, given that 3 erasers cost $4.41, would be $5.88.

The correct equation that represents this relationship and would help determine the cost of 4 erasers is:

[tex]\[ \frac{4}{x} = \frac{3}{4.41} \][/tex].

complete question given below:

Simply take 4.4% of $3:

0.044 * 3 = 0.132

You would pay $0.13 tax on a $3 item.

Answer:

A.

Step-by-step explanation:

We have that C>0, D>o and C > D. Now,

A. [tex](C+D)^2= C^2+2CD+D^2[/tex]

B. 2(C+D) = 2C+2D

C. [tex]C^2+D^2[/tex]

D. [tex]C^2-D^2[/tex]

We have that [tex]C^2+2CD+D^2> C^2+D^2[/tex] (beacuse on left we have adding one extra positive term) and also [tex]C^2+D^2> C^2-D^2[/tex] (adding two positive values is greater than subtract two positive values), then

[tex]C^2+2CD+D^2> C^2-D^2[/tex]

also, [tex]C^2+2CD+D^2> 2C+2D[/tex] (also because the middle term). Then, the largest term is  [tex](C+D)^2= C^2+2CD+D^2[/tex].

To make 120 caramel peanut butter bars, using a recipe that calls for 14 ounces of caramel for 36 bars, one would need 47 ounces of caramel (rounded to the nearest ounce).

Given that a cookie recipe for three dozen caramel peanut butter bars uses 14 ounces of caramel, we need to determine the amount of caramel needed to make 120 bars. Since three dozen bars are equal to 36 bars, we can find how many times the amount of bars in the recipe fits into the desired 120 bars count by dividing 120 by 36.

This gives us 120 / 36 = 3.33. Multiplying this factor by the amount of caramel used for 36 bars gives us the amount needed for 120 bars: 3.33 * 14 ounces = 46.62 ounces. Therefore, 47 ounces of caramel (rounding to the nearest ounce) should be used to make 120 bars for a cookie exchange.
