Answer:
31.5 units^2
Step-by-step explanation:
This is a right triangle
The x dimension is from B to C
-4 to 3 is 7 units
The y dimension is from A to B
5 to -4 = 9 units
The area of a triangle is
A = 1/2 bh
A = 1/2 (7)(9)
= 31.5
Answer:
First one:
31.5 units²
Step-by-step explanation:
AB: 5 - (-4) = 9 units
BC: 3 - (-4) = 7 units
ABC is a right angle triangle with 90° at B
Base: BC
Height: AB
Area:
½ × base × height
½ × 7 × 9

and hits the ground with a speed of
33.8 m/s
Answer:
3m/s or option 1
Step-by-step explanation:
Given,
Height(h)=90m
time(t)=30s
Speed(v)=?
Now,
Speed(v)=distance/time
v=height/time(Since,height here is the distance covered by the balloon)
v=90/30
v=3
Unit of speed is m/s
Therefore,v=3m/s

A line passes through the point (6,-6) and has a slope of 3/2. Write a equation in point-slope form for this line
Answers
Answer: [tex]y+6=\frac{3}{2} (x-6)[/tex]
Step-by-step explanation:
use the equation [tex]y-y_{1} =m(x-x_{1})[/tex]
we know the slope, y, and x, so plug in
[tex]y-(-6)=\frac{3}{2} (x-(6))[/tex]
[tex]y+6=\frac{3}{2} (x-6)[/tex]
Answer:
[tex]y=\frac{3}{2}x-15[/tex]
Step-by-step explanation:
The point-slope equation is [tex]y-y_{1} =m(x-x_{1} )[/tex]
Here our m is our slope which is [tex]\frac{3}{2}[/tex] and our [tex](x_{1},y_{1})[/tex] point is (6, -6)
Plugging in these values to our equation gives us
y - (-6) = [tex]\frac{3}{2}[/tex](x - 6) → distribute the negative to the -6 on the left side and then distribute the [tex]\frac{3}{2}[/tex] to the x term and the -6 on the right side → y + 6 = [tex]\frac{3}{2}x[/tex] - 9 → then subtract the 6 from both sides → [tex]y=\frac{3}{2} x-15[/tex]

A square pyramid has a base with a total area of 144 m2 and the volume of 384m3, what is the slant height of the pyramid
Answers
Answer:
8mStep-by-step explanation:
Volume of a square based pyramid is expressed as [tex]V = a^{2} \frac{h}{3}[/tex] where;
a is the base edge
a² is the base area
h is the slant height
Given Volume of the pyramid V = 384m³

If I have a probability of 2/5, what is the percentage of probability.
A. 52%
B. 40%
C. 2.5%
D. 80%
Answers
2 divide by 5= 0.4 which equals to 40%
Answer: 40%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 2/5 as a percent, we need to find a fraction equivalent to 2/5 that has a 100 in the denominator.
We can do this by setting up a proportion.
[tex]So[/tex] [tex]we[/tex] [tex]have[/tex] [tex]\frac{2}{5} = \frac{n}{100}[/tex].
Now, we can use cross-products to find the missing value.
So we have (2)(100) which is 200 is equal to (5)(n) or 5n.
So we have 200 = 5n.
Next, dividing both sides of the equation by 5, we have 40 = n.
So 2/5 is equal to 40/100 or 40%.
2/5 of it is 22.\

The hourly wages earned by 20 employees are shown in the first box-and-whisker plot below. The person earning $15 per hour quits and is replaced with a person earning $8 per hour. The graph of the resulting salaries is shown in plot 2. A box-and-whisker plot is shown. The number line goes from 7 to 15. The whiskers range from 8 to 15, and the box ranges from 8.8 to 10.2. A line divides the box at 9.5. Plot 1 A box-and-whisker plot is shown. The number line goes from 7 to 15. The whiskers range from 8 to 11, and the box ranges from 8.7 to 10. A line divides the box at 9.6. Plot 2 How does the mean and median change from plot 1 to plot 2? The mean and median remain the same. The mean decreases, and the median remains the same. The mean remains the same, and the median decreases. The mean and median decrease.
Answers
Answer:
The mean decreases, and the median remains the same.Step-by-step explanation:
Remember that a box plot is made by the quartiles of the distribution, the maximum value and the minimum value. So, from a box plot we can deduct the range, the median and the interquartile range.
In this case, the median remains the same at $9.5 per hour. The median is indicated by the middle line of the box, and you can observe that it doesn't change.
Now, the range of the data set decreases from 7 to 3.
On the other hand, the mean must decrease, because data greater than $11 doesn't exist in the box plot number 2, and the mean is a central measure sensible to those changes.
Therefore, the right answer is The mean decreases, and the median remains the same.

Answer:
The corresponding base is 12 cm.
Step-by-step explanation:
The area of a parallelogram is calculated with the formula of A=bh, where b is the base and h is the height.
You can apply the problem to the formula:
420=b(35)
To solve, work backwards.
Divide 35 to both sides.
420 divided by 35 is 12

If you need 4 tables spoons of golden syrup to make 10 cupcakes, how many tables spoons of golden syrup will you need to make 4 cupcakes.
Answers
Answer:
1.6 tablespoons
Step-by-step explanation:
Let’s make a proportion
syrup/cupcakes=syrup/cupcakes
4 tablespoons are needed for 10 cupcakes and x tablespoons are needed for 4 cupcakes.
4/10=x/4
Now we have to solve for x. x is being divided by 4. To reverse this, multiply both sides by 4, because multiplication is the opposite of division.
4*4/10=x/4*4
The 4s on the right will cancel, so we are left with:
4/4*10=x
1.6=x
So, 1.6 tablespoons are needed for 4 cupcakes.
