The bases of a trapezoid are 16.8 yards and 6.9 yards. If the height is 2 yards, what is the area of the
trapezoid?
47.4 yd 2
9.9 yd 2
23.7 yd 2
19.8 yd 2
Given:
Bases of a trapezoid are 16.8 yards and 6.9 yards.
The height is 2 yards.
To find:
The area of the trapezoid.
Solution:
We know that, area of a trapezoid is
[tex]Area=\dfrac{\text{Sum of bases}\times \text{Height}}{2}[/tex]
Using this formula, we get
[tex]Area=\dfrac{(16.8+6.9)\times 2}{2}[/tex]
[tex]Area=\dfrac{(23.7)\times 2}{2}[/tex]
[tex]Area=23.7\text{ yards}^2[/tex]
Therefore, the correct option is C.
Answer:
the answer is 19.8 yd 2

An object is moving at a speed of 7 meters every 9 days. Express this speed in centimeters per year. Round your answer to the nearest whole number.
Answer:
28400cm
Step-by-step explanation:
if 9 days=7m
:.365 days=?
365×7/9
283.88888
rounded off to nearest whole number =284m
change to cm=28400cm
The speed of the object expressed in centimeters per year and rounded to the nearest whole number is 28390 cm/yr
Speed per day = Distance / Number of days
Speed per day = 7 meters ÷ 9 days = 0.7778 m/day
Converting to centimeters per year :
1 meter = 100 cm1 day = 1/365 yearsHence,
0.7778 m/day = (0.7778 × 100cm) ÷ (1/365 years)
(0.7778 × 100cm) ÷ (1/365 years) = (77.78 cm ÷ 0.0027397 year)
0.7778 m/day = 28389.7 cm / year
Therefore, the speed of the object is 28390 cm/yr

Charles wants to compare the solutions to the equations x^2=64 and x^3=64.
Compare the signs of the solutions. Explain your reasoning.
Answer:
x = ±4
x = 4
Step-by-step explanation:
x² = 64.
Square root both sides
√x² =√64
x= ±8
When squaring both sides, the required solution is both positive and negative since the product of two negative number is positive.
x³ = 63.
Cube root both sides
3√x³ = 3√65
x =4
This only gives a positive number not negative since the product of three negative number gives a negative number

Can someone please help me this problem? Thanks :)
Answer: B) 2/3
====================================================
Work Shown:
Method 1
Apply the slope formula
m = (y2-y1)/(x2 - x1)
m = (3-1)/(-1 - (-4)) ..... using the first two rows as points
m = (3-1)/(-1 + 4)
m = 2/3 is the slope
-----------------------------------
Method 2
Each time y goes up by 2, x goes up by 3.
For instance, the jump from y = 1 to y = 3 is "plus 2". At the same time, the jump from x = -4 to x = -1 is "plus 3".
We can then say
slope = (rise)/(run)
slope = (change in y)/(change in x)
slope = (y increase by 2)/(x increase by 3)
slope = 2/3
