What resources were brought from Europe to exchange for slaves

Length = 12 m and width = [tex]\frac{7}{2}[/tex] m.

Solution:

Let the width of the rectangle be w.

Length of the rectangle = 2w + 5

Area of the rectangle given = 42 m²

Area of the rectangle = length × width

length × width = 42

(2w + 5) × w = 42

[tex]2w^2+5w=42[/tex]

Subtract 42 from both sides, we get

[tex]2w^2+5w-42=0[/tex]

Using quadratic formula,

[tex]$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]

Here, [tex]a=2, b=5, c=-42[/tex]

[tex]$w=\frac{-5 \pm \sqrt{5^{2}-4 \cdot 2(-42)}}{2 \cdot 2}[/tex]

[tex]$w=\frac{-5 \pm \sqrt{25+336}}{4}[/tex]

[tex]$w=\frac{-5 \pm \sqrt{361}}{4}[/tex]

[tex]$w=\frac{-5 \pm19}{4}[/tex]

[tex]$w=\frac{-5+19}{4}, w=\frac{-5-19}{4}[/tex]

[tex]$w=\frac{14}{4}, w=\frac{-24}{4}[/tex]

[tex]$w=\frac{7}{2}, w=-6[/tex]

Dimension cannot be in negative, so neglect w = –6.

Width of the rectangle = [tex]\frac{7}{2}[/tex] m

[tex]$L=2(\frac{7}{2} )+5=12 \ m[/tex]

Hence length = 12 m and width = [tex]\frac{7}{2}[/tex] m.

Answer:

75

Step-by-step explanation:

you have 600 = 8 and you want to break it down into just 1 hour so you divide both sides by 8

600/8 = 75

Final answer:

The student was traveling at a speed of 75 miles per hour.

Explanation:

To calculate the speed in miles per hour when a student has traveled 600 miles in 8 hours, you divide the total distance by the total time taken. The formula to find speed is:

Speed = Distance / Time

So, if we plug in the values we have:

Speed = 600 miles / 8 hours = 75 miles per hour

Therefore, the student was traveling at a speed of 75 miles per hour.

Answer:

y=3x+4

Step-by-step explanation:

The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

[tex]y = mx + b[/tex]

where m=3 is the slope .

We substitute the slope to get:

[tex]y = 3x + b[/tex]

We substitute the point to find b.

[tex] - 5 = 3( - 3) + b \\ - 5 = - 9 + b \\ b = - 5 + 9 = 4[/tex]

The equation of the straight line is:

[tex]y = 3x + 4[/tex]

6x divided by 6 will be equal to x.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that 6x is divided by 6. The solution will be done as below:-

E = 6x / 6

Divide 6 by 6 we will get 1. The value of expression will be:-

E = x

Therefore, 6x divided by 6 will be equal to x.

Answer: Eleventh Grade

Step-by-step

The ratio of tenth graders to the school's total population is 86:255 = 33.7%.

The ratio of eleventh graders to the school's total population is 18:51 = 35.3%.

Since the probability of a student being in either tenth, eleventh, or twelfth grade = 1 = 100% (that is, certainty), then the probability of a randomly drawn student being in twelfth grade is (100-33.7-35.3)% = 31.0%.

When randomly choosing one student from the whole school, it is most likely (35.3%) that the student is in the eleventh grade.

To estimate the dealer's cost, calculate 90% of the base price and 87% of the options price. Add the dealer's cost of the base price and options price to find the estimated dealer's cost.

To estimate the dealer's cost, we need to find 90% of the base price and 87% of the options price.

Therefore, the estimated dealer's cost is $15,982.65.

Step-by-step explanation:

Two expressions are equivalent if we can arrange one of them in order to match the other.  If we evaluate the two expressions for certain values in the input, we must get the same value in the output. In this exercise, we have the following expression:
