Can someone see if my answers are correct!
Sorry i keep asking questions lol, im just really struggling with math and my teacher wont answer my emails! And my mom doesn't understand any of this even though she's good at math! :(
Answers
Answer:
Step-by-step explanation:
The cross sectional area of a basketball would indeed be a circle. The units for surface area would be meters squared. The units meters cubed would be volume. Area is inherently a 2-dimensional problem. Therefore, having 3-dimensional units makes no sense. In your case, the correct answer would be yards squared

Use the translation vector <−4, 7> to determine the rule for translation of the coordinates: (x,y)→(x+(−4),y+7).
Apply the rule to translate vertices J(−3,5), K(−1,0) and L(8,−4).
J(−3,5)→(−3+(−4),5+7)→J'(−7,12).
K(−1,0)→(−1+(−4),0+7)→K'(−5,7).
L(8,−4)→(8+(−4),−4+7)→L'(4,3).
To apply the reflection across x-axis use the rule for reflection: (x,y)→(x,−y).
Apply the reflection rule to the vertices of △J'K'L'.
J'(−7, 12)→J''(−7,−12).
K'(−5,7)→K''(−5,−7).
L'(4,3)→L''(4,−3).
Therefore,
J(−3,5)→J'(−7,12)→J''(−7,−12)K(−1,0)→K'(−5,7)→K''(−5,−7)
L(8,−4)→L'(4, 3)→L''(4,−3)
represents the translation of △JKL along vector <−4, 7> and its reflection across the x-axis.

Let x² + 15x = 49 . What values make an equivalent number sentence after completing the square? Enter your answers in the boxes.
x² + 15x + = [ ]
Answers
Answer:
Step-by-step explanation:
15/2 = 7.5 and (7.5)^2 = 56.25 so
x^2 + 15x + 56.25 = 49 + 56.25
x^2 + 15x + 56.25 = 105.25.
Answer:
[tex]x^2+15x+\boxed{\dfrac{225}{4}}=\boxed{\dfrac{421}{4}}[/tex]
[tex]x^2+15x+\boxed{56.25}=\boxed{105.25}[/tex]
Step-by-step explanation:
General form of a quadratic equation: [tex]ax^2+bx+c[/tex]
When completing the square, first add the number that is the square of half of [tex]b[/tex].
Given equation: [tex]x^2+15x=49[/tex]
Therefore, [tex]b=15[/tex]
[tex]\implies \left(\dfrac{b}{2}\right)^2=\left(\dfrac{15}{2}\right)^2=\dfrac{225}{4}[/tex]
So we need to add 225/4 to both sides of the equation:
[tex]\implies x^2+15x+\dfrac{225}{4}=49+\dfrac{225}{4}[/tex]
[tex]\implies x^2+15x+\boxed{\dfrac{225}{4}}=\boxed{\dfrac{421}{4}}[/tex]
In decimal form:
[tex]\implies x^2+15x+\boxed{56.25}=\boxed{105.25}[/tex]
To finish completing the square,
factor the left side of the equation:
[tex]\implies \left(x+\dfrac{15}{2}\right)^2=\dfrac{421}{4}[/tex]
Finally, subtract 421/4 from both sides:
[tex]\implies \left(x+\dfrac{15}{2}\right)^2-\dfrac{421}{4}=0[/tex]
In decimal form:
[tex]\implies (x+7.5)^2-105.25=0[/tex]
On Monday,221 students went on a trip to the zoo.all 4 buses were filled and 5 students had to travel in cars how many students were in each bus
Answers
Answer:
54
Step-by-step explanation:
If 5 students went in cars then 216 students were in the buses (221-5=216)
There were four buses so divide 216 by 5 which is 54.
So there were 54 students in each bus
Answer:
54
Step-by-step explanation:
If you have 221 students going to the zoo and 5 that went to the zoo in cars you only need to account for the 216 travelling by bus. So you subtract 5 from 221 and divide what you have left over (216) by 4 for the 4 buses you're using.
216/4= 54

p = [tex]-\frac{15}{2}[/tex], p = [tex]\frac{17}{2}[/tex]
Step-by-step explanation:
1. Subtract 15 from both sides:
- |2p -1| = -16
2. Divide both sides by -1:
[tex]\frac{-|2p - 1|}{-1} = \frac{-16}{-1}[/tex]
|2p - 1| = 16
3. Apply the absolute value rule (If |u| = a, a > 0, then u = a, or u = -a)
2p - 1 = 16 or 2p - 1 = -16
4. Solve for the positive and negative intervals:
2p - 1+1 = 16+1
2p = 17
[tex]\frac{2p}{2} = \frac{17}{2}[/tex]
p = [tex]\frac{17}{2}[/tex]
2p - 1+1 = -16+1
2p = -15
[tex]\frac{2p}{2} = \frac{-15}{2}[/tex]
p = [tex]\frac{-15}{2}[/tex]

The measure of angle BOC is 28.65°.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
The area of a triangle is,
Area = 1/2 × base × height
We have radius of the circle is 12 inches since OA = 12 which is the radius.
So, OB = 12 inches.
Height of the triangle AOB to the base OA = 12 sin (30°) = 12/2 = 6 inches
Area of ΔAOB = 1/2 × 12 × 6 = 36 inches²
Area of sector = (x/360°) πr², where r is the radius and x is the central angle formed.
Here x is ∠BOC.
Since area of sector = area of triangle,
(x/360°) π(12)² = 36
x π = 90°
x = 28.65°
Hence the required measure is 28.65°.
