Shown is a triangle
x + 20
2x-20
2x 40
Work out the value of
Answer:
x = 44
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 20 + 2x - 40 + 2x - 20 = 180, that is
5x - 40 = 180 ( add 40 to both sides )
5x = 220 ( divide both sides by 5 )
x = 44
Use FOIL to explain how to find the product of
(a + b)(a − b). Then describe a shortcut that you could use to get this product without using FOIL.
Answer:
A² + 2AB - B²
Step-by-step explanation:
Answer:
Multiply the first, outside, inside, and last terms of the binomials.
Multiply a times a, a times -b, b times a, and b times -b.
This is the same as just squaring a and squaring b.
A shortcut is to add a squared and b squared

Answer:
0.8
Step-by-step explanation:
Divide the numerator and denominator together to find the answer.
19 / 24 = 0.79166...
Round to the nearest tenth.
0.79166... → 0.8
Best of Luck!
Answer:
0.8
Step-by-step explanation:
numerator ÷ denominator = 0.791..
19 / 24 = 0.791..
0.791 to the tenth is 0.8
Hope this helps :)
Find BA
CB + BA = CA
7x-2 + 5x+1 = 23
Answer:
BA = 11
Step-by-step explanation:
CB + BA = CA , substitute values
7x - 2 + 5x + 1 = 23, that is
12x - 1 = 23 ( add 1 to both sides )
12x = 24 ( divide both sides by 12 )
x = 2
Thus
BA = 5x + 1 = 5(2) + 1 = 10 + 1 = 11

5) Ziegler is using paper for an art project
thatis 0.025 mm thick. If she glues a layer
of thepaper onto a construction board with
athickness of 7 * 10^-2 mm, what will the
total thickness of the paper and the
construction
board be? Write your ansicer
in scientific notation
Answer:
9.5 * 10^-2 mm
Step-by-step explanation:
To find the total thickness, we proceed to add the two thickness that we have
Mathematically, this will be;
0.025 mm + 7 * 10^-2 mm
7 * 10^-2 mm = 0.07
So we have;
0.025 mm + 0.07 mm = 0.095
In scientific notation, this is 9.5 * 10^-2 mm
Three drivers competed in the same fifteen drag races. The mean and standard deviation for the race times of each of the drivers are given.
- Driver A had a mean race time of 4.01 seconds and a standard deviation of 0.05 seconds.
- Driver B had a mean race time of 3.96 seconds and a standard deviation of 0.12 seconds.
- Driver C had a mean race time of 3.99 seconds and a standard deviation of 0.19 seconds.
Which driver do you predict will win the next drag race? Support your prediction using the mean and standard deviation.
Answer:
Driver B
Step-by-step explanation:
From the given options, Driver B will win the next race because the previous result shows that Driver B has the fastest race time due to the fact that it recorded the lowest mean race time.
Similarly, the standard deviation of 0.12 seconds illustrates that the driver keep-up with the bearest minimum time frame all through the entire race time.
Answer:
It is B and the other one is Driver C if you have that question

Callan goes for a hike every Saturday. Callan hikes at a rate of 3 miles per hour.
Complete the table for the given ratio.
Answer:
(1) 27 meters. (2, 3) Both distances in miles (y) are 10 miles (y)
Step-by-step explanation:
For the first question, every mark represents 9 meters. and 9 multiplied by 3 is 27.For the second half, look at the y section and see that the dots are a line higher than 9. So they both have 10 as y.

If a figure starts off in a Quadrant I and is reflected along the x-axis and then rotated 180 degrees about the origin, what quadrant will it land on?
Answer:
Quadrant 2
Step-by-step explanation:
First you reflect and it goes to Quadrant 4(Positive,Negative). When rotating 90 degrees you go to the next quadrant. In this case it is 180 degrees, so it ends up two quadrants away. The final location is quadrant 2

Calculate the shortest distance between P and Q.
Answer:
10.6 cm
Step-by-step explanation:
Shortest distance between P(3, -1) and Q(-5, 6) using [tex] PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Plug in the values
[tex] PQ = \sqrt{(-5 - 3)^2 + (6 -(-1))^2} [/tex]
[tex] PQ = \sqrt{(-8)^2 + (7)^2} [/tex]
[tex] PQ = \sqrt{64 + 49} [/tex]
[tex] PQ = \sqrt{113} = 10.6 [/tex] (1 d.p)
