Calculate the area of triangle ABC with altitude CD, given A(−7, −1), B(−1, 5), C(0, 0), and D(−3, 3). 9 square units 18 square units 18.5 square units 21 square units
9514 1404 393
Answer:
18 square units
Step-by-step explanation:
Referring to the figure, we see that the base AB has a slope of 1, and the altitude CD has a slope of -1. The number of unit squares crossed by these segments are, respectively 6 and 3, so the length of each is ...
AB = 6√2
CD =3√2
The area is half the product of the base (AB) and height (CD) so is ...
A = 1/2bh = (1/2)(6√2)(3√2) = 18
The area of ΔABC is 18 square units.

Additional comment
It is useful to remember that the diagonal of a unit square is √2. We used that fact here. If you need to figure it using the Pythagorean theorem, you find ...
c² = a² +b²
c = 1² +1² = 2
c = √2

Look at the triangular prism. Work out the volume of the prism.
Answer:
See explanation
Step-by-step explanation:
The question has missing details, as the diagram of the prism is not shown.
However, I'll solve using a general rule.
The volume of a triangular prism is:
[tex]Volume = \frac{1}{2}* b * h * l[/tex]
Where
[tex]b = base[/tex]
[tex]h = height[/tex]
[tex]l = length[/tex]
Take for instance:
[tex]b = 20cm[/tex]
[tex]h = 10cm[/tex]
[tex]l = 5cm[/tex]
The volume is:
[tex]Volume = \frac{1}{2} * 20cm * 10cm * 5cm[/tex]
[tex]Volume = 10cm * 10cm * 5cm[/tex]
[tex]Volume = 500cm^3[/tex]
Another instance (see attachment).
From the attachment:
[tex]b = 4.5cm[/tex]
[tex]h = 5cm[/tex]
[tex]l = 8cm[/tex]
The volume is:
[tex]Volume = \frac{1}{2} * 4.5cm * 5cm * 8cm[/tex]
[tex]Volume = 2.25cm * 5cm * 8cm[/tex]
[tex]Volume = 90cm^3[/tex]

There are 347 students going on a field trip. Each bus holds 44 students. If each bus costs $95, is the total cost of the buses more than $1,000? Estimate, then find the exact answer.
Answer:
Total cost= $760
Step-by-step explanation:
Giving the following information:
Number of students= 347
Each bus holds 44 students.
Bus cost= $95
First, we need to determine the number of buses needed:
Number of buses= total students / student per bus
Number of buses= 347 / 44
Number of buses= 7.88 = 8 buses
Now, the total cost:
Total cost= 8*95
Total cost= $760
4.) 960 meters in 15 seconds
Write the following rate as a unit rate
Answer:
64
Step-by-step explanation:
960 divided by 15 is 64. The unit rate means one so you are trying to get it to 1 second so just do 15 divided by 15 which is 1, then 960 divided by 15 which is 64

1. It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle. 2. The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°. 3. The sum of the lengths of any two sides of a...

3x-9=7x+14 solve for x
Answer:
x= - 23/4
Step-by-step explanation:
Add 9 to both sides of the equation:
3x -9 = 7x +14
3x- 9 + 9 = 7x +14 +9
Simplify:
3x -9 + 9 = 7x +14 +9
3x = 7x +14 +9
3x =7x +14 +9
Subtract 7x from both sides of the equation:
3x= 7x +23
3x -7x = 7x +23 - 7x
Simplify Again:
3x -7x = 7x +23 -7x
-4x =23
Combine like terms:
-4x =23
Divide both sides of the equation by the same terms:
14x/ 14 = 23/ -4
Cancel terms that are both the numerator and the denominator:
x= - 23/- 4
Answer:
x= - 23/4
How is 80.106 written in expanded form?
Plzzzz answer asap
Answer:
[tex]80.106= 8 * 10 + 0 * 1 * 0.1 + 6 * 0.001[/tex]
Given:
80.106
Required:
Write in expanded form
First, we need the place value of each digit:
Next, we multiply each digit by its place value, to give the expanded form;[tex]8- > Tens- > 10\\0- > Units- > 1\\1- > Tenths- > 0.1\\0- > Hundreds- > 0.01\\6- > Thousands- > 0.001[/tex]
[tex]80.106= 8 * 10 + 0 * 1 * 0.1 + 6 * 0.001[/tex]

What decimal is equivalent to 4/15
Hey there!
In order for you to find out the decimal form a fraction, just simply DIVIDE the NUMERATOR (TOP number) from the DENOMINATOR (BOTTOM number) and you should be able to find out your answer!
Formula:
NUMERAATOR / DENOMINATOR = ANSWER
NUMERATOR ➡️ 4
DENOMINATOR ➡️ 15
4 / 15 = answer
4 / 15 = 2.667
POSSIBLE ANSWER: 2.667 ☑️
