right triangles to find the exact length of:
T
30°
14 in
a) TI = in
60°
R
a) TI = 7√3 in
b) IR = 7 in
Explanation:Using cosine rule:
[tex]\sf cos(x) = \dfrac{adjacent}{hypotenuse}[/tex]
[tex]\hookrightarrow \sf cos(30) = \dfrac{TI}{14}[/tex]
[tex]\hookrightarrow \sf TI = 14cos(30)[/tex]
[tex]\hookrightarrow \sf TI = 7\sqrt{3}[/tex]
Using sine rule:
[tex]\sf sin(x) = \dfrac{opposite}{hypotenuse}[/tex]
[tex]\hookrightarrow \sf sin(30) = \dfrac{IR}{14}[/tex]
[tex]\hookrightarrow \sf IR = 14sin(30)[/tex]
[tex]\hookrightarrow \sf IR = 7[/tex]

Answer:
130 m²
Step-by-step explanation:
Area of a parallelogram is given by the formula :
A = bh (b is the base length and h is the perpendicular height)
Now we simply substitute values given in diagram to find our answer:
A = bh
A = (13)(10)
A = 130
Units will be m² as this is area

Answer:
(-1,4)
Step-by-step explanation:
For x the midpoint between -2 and 0 is -1
for y the midpoint between -1 and 9 is 4
Answer:
(-1,4)
Step-by-step explanation:
Midpoint can be found by:
(x1+x2)/2 ; (y1+y2)/2
So, if we substitute, we can find:
(-2+0)/2 ; (-1+9)/2
This gives us -2/2 and 8/2, which is:
(-1, 4)

If it takes 10gallons of gas to travel 130 miles. Plot a chart showing the distance covered by 25 gallons, 30 gallons and 32 gallons of gas.
PLEASE ANSWER QUICKLY
Answer:
325, 390, 416
Step-by-step explanation:
So, to find one gallon, we can do 130/10=13. So, we can multiply 13 by the other numbers. 25x13=325, 30x13=390, and 32x13=416.

Answer:
Center is [tex](8,-1)[/tex]
Radius is [tex]3[/tex]
Step-by-step explanation:
To convert from a general form equation to a standard form equation, we must complete the square for each variable to simplify. Make sure to rearrange the equation to complete the square more easily:
[tex]x^2+y^2-16x+2y+56=0\\\\x^2-16x+56+y^2+2y=0\\\\x^2-16x+56(+8)+y^2+2y(+1)=0+8+1\\\\x^2-16x+64+y^2+2y+1=9\\\\(x^2-16x+64)+(y^2+2y+1)=9\\\\(x-8)^2+(y+1)^2=9[/tex]

The circumference of a circle is 37.68 meters. What is the circle's diameter?
C = 37.68 m
Use 3.14 for л.
Answer:
The diameter is 12.
Explain: i used this formula C= Dπ or C= 2rπ
(37.68) = Dπ Divide by 3.14, as the instructions in this question specify to do so.
37.68/3.14 = D π/ 3.14
D = 12 The diameter equals twelve.

Step-by-step explanation:
1) Parallelepiped
We need to find its surface area minus the area of the base and the base of the cylinder above.
2 (9) (2.4) = 43.2
2 (5) (2.4) = 24
4pi = Area of the base of the cylinder
45 - 4pi = Area of the base of the parallelepiped minus covered region.
Surface needed = 112.2 - 4pi
2) Cylinder
We need to find its surface area minus the area of the base.
2 (pi) (2) (3) = 12pi
pi (4) = 4pi
Surface needed = 16pi
Total surafec needed: (112.2 - 4pi) + 16pi = 112.2 + 12pi
(This is solved in 'pi' terms)

The probability of sandy flipping a coin twice and getting heads both times is 0.25 the probability of john's spinner stopping on the color red is
The true statement is (c) Neither. Both events are equally likely.
Complete questionThe probability of Sandy flipping a coin twice and getting heads both times is 0.25. The probability of John's spinner stopping on the color red is 1/4.
Which of these events is more likely?
-Sandy flips a coin twice and gets heads both times.
-John's spinner stops on the color red.
-Neither. Both events are equally likely.
How to determine the likely event?The given parameters are:
P(Head twice) = 0.25
P(Red) = 1/4
Rewrite P(Red) as:
P(Red) = 0.25
By comparison, we have:
P(Red) = P(Head twice) = 0.25
This means that both events are equally likely
Hence, the true statement is (c)
