The expression is [tex]\sqrt{81} -(-1*-3*\sqrt{4})[/tex] Type the expression into a calculator.
Please write a proof
Answer:
Step-by-step explanation:
∠X ≅∠Z : Given
∠ZYV≅∠XYU
∠ZVY≅∠XUY Because ∠ZYV≅∠XYU, ∠X ≅∠Z.
So ∠YVW≅∠YUW
Draw VU
ΔVWU is an isosceles triange so ∠UVW≅∠VUW
So ∠YVU≅∠YUV
Therefore ΔYVU is also an isosceles triangle and YV = YU
So ΔZYV≅ΔXYU ( ASA)
So XU = ZV ( because of CPCTC)
Therefore XU + WU = ZV = VW : XW = ZV
ΔXWV ≅ΔZWU ( ASA)
The triangles in the picture are congruent by which method
Answer:
ASA

24. Michael leaves his house at 0837 and travels by motorcycle to the railway station, which is 27 km from his
house.
(i) If he arrives at the station 36 minutes later, find the average speed at which he travels in km/h.
(ii) If the train, which is due at 0942, is 11 minutes late, how long will he have to wait?
Answer:
i) 45km/hr
ii)29 min
Step-by-step explanation:
average speed = distanced travelled / time elapsed
It took 36min and need to convert to hr
36min x [tex]\frac{hours}{60 min}[/tex] = [tex]\frac{36 hr}{60 min}[/tex] = [tex]\frac{9 }{15 }[/tex] hours
distanced travelled is 27 km;
average speed = 27km / (9/15hr) = 45 km/hr
Add 36min to 0837 becomes 0913, the train will arrive at 0942 and the wait will be the difference of 0942 - 0913 = 29 min

Answer:
sin^2(a) I believe. Delete my response if needed.
Step-by-step explanation:
tan²(α) (2 cos²(α) + sin²(α) - 1)
Recall that sin²(α) + cos²(α) = 1 for all α. Then sin²(α) - 1 = -cos²(α) :
tan²(α) (2 cos²(α) - cos²(α))
tan²(α) cos²(α)
Rewrite tan(α) = sin(α) / cos(α) :
(sin(α) / cos(α))² cos²(α)
(sin²(α) / cos²(α)) cos²(α)
Cancel the factors of cos²(α) :
sin²(α)
01:29:01 Nikhil gets paid a 5 percent commission on every pair of shoes that he sells. He earned $1.00 on the last pair of shoes that he sold. The expression that can be used to represent x, the price of the shoes, is 0.05 x = 1 What was the price of the shoes?
Answer:
the price of the shoes is $20
Step-by-step explanation:
According to the question, The computation of the price of the shoes is shown below:
Data provided in the question
0.05x = 1
Based on the above information
We now solve for x
x = 1 ÷ 0.05
It can be written as
= 100 ÷ 5
= $20
hence, the price of the shoes is $20

The battery life for Bruhier's cell phone is longer when he has fewer apps running. When only one app is running, the battery will last for
16 hours. When four apps are running, the battery will only last for 4 hours.
This situation represents
variation.
The constant of variation, k, is equal to
If eight apps are running, Bruhler's battery will last for 4 hours
Answer:
inverse, 16, 4
Step-by-step explanation:
The constant of variation when eight apps are running, battery lasts for 4 hours is 32.
What is Inverse Variation?When a variable varies inversely with the other variable, i.e. on increasing one variable the other decreases is called Inverse Variation.
The battery life varies inversely with the number of apps running
The battery life is denoted by b
and the number of apps is denoted by a
then
[tex]\rm b\; \alpha \; (1/a)\\\\b = k /a[/tex]
here k is the proportionality constant
The battery lasts for 16 hours when the apps opened is 1
The battery lasts for 4 hours when the apps opened is 4
16 = k
The constant of variation when eight apps are running, battery will last for 4 hours
[tex]\rm 4 = k /8[/tex]
k = 32
