What is the area of the trapezoid? A trapezoid has a base of 12 centimeters, a height of 16 centimeters, and a top side length of 10 centimeters. 176 cm2 192 cm2 208 cm2 224 cm2
Answer:
176
Step-by-step explanation:
option a ( 176 cm²)
A trapezoid has a base of 12 centimeters, a height of 16 centimeters, and a top side length of 10 centimeters.
To find the area, we use the formula for the area of a trapezoid:
Area = 1/2 × (Base1 + Base2) × Height
Here, Base1 is 12 cm,
Base2 is 10 cm, and
the height is 16 cm.
the sum of the bases:
12 cm + 10 cm
= 22 cm.
Multiply by the height:
22 cm × 16 cm
= 352 cm².
Divide by 2 to get the area:
352 cm² ÷ 2
= 176 cm².
So, the area of the trapezoid is 176 cm².

2. Fred and Mary Merrill want to purchase a new car. The car has a base
price of $16,700, options totaling $1.095, and a destination charge of

O
$16,307.65
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.
Explanation:To estimate the dealer's cost, we need to find 90% of the base price and 87% of the options price.
90% of $16,700 (base price) = $16,700 x 0.90 = $15,03087% of $1,095 (options price) = $1,095 x 0.87 = $952.65Adding the dealer's cost of the base price and options price: $15,030 + $952.65 = $15,982.65Therefore, the estimated dealer's cost is $15,982.65.

O B. y= 3x - 14
OC. y= 3x-4
OD. y = 3x + 12

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.

-7 = -1 + [tex]\frac{x}{3}[/tex]
To solve this you must isolate x.
On the right side of the equation the one is negative. To cancel the -1 from the right side you must add 1 to both sides (what you do to one side you do to the other) since addition is the opposite of subtraction (negative). Doing this will make -1 zero on the right side of the equation and bring it over to the left side
-7 + 1 = -1 + 1 + [tex]\frac{x}{3}[/tex]
-6 = 0 + [tex]\frac{x}{3}[/tex]
-6 = [tex]\frac{x}{3}[/tex]
The x is being divided by 3 and the opposite of division is multiplication. To completely isolate x you must multiply 3 to both sides. This will cancel the three out on the right side of the equation and bring it over the left side.
-6 * 3 = [tex]\frac{x}{3}[/tex] * 3
-18 = x
Now check:
-7 = -1 + [tex]\frac{-18}{3}[/tex]
-7 = -1 + (-6)
-7 = -7
^^^This is true which means that x = -18

17. Only tenth-, eleventh-, and twelfth-grade students
attend Washington High School. The ratio of tenth
graders to the school's total student population is
86:255, and the ratio of eleventh graders to the
school's total student population is 18:51. If 1 student
is chosen at random from the entire school, which
grade is that student most likely to be in?
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.

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.

600 miles in 8 hours
_?_ miles per hour
(number answer only)
Question
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.
