siny=s/8
tany=s/t

$\\ \tt\longmapsto cosy=\dfrac{siny}{tany}$

$\\ \tt\longmapsto cosy=\dfrac{s/8}{s/t}$

$\\ \tt\longmapsto cosy=8/t$

Secy=1/cosy=t/8

Please help me <br>ineed it now

yanalaym [24]

Answer:

look at explanation

Step-by-step explanation:

To solve all of these questions you just need to scale. While scaling you can divide or multiply.

1. $\frac{180 km}{4 hrs}$ (divide by 4 to get unit rate)

unit rate = $\frac{45km}{1hr}$

2. If it takes one hour to travel 40 miles, then we don't have to scale or anything. We know $\frac{40 miles}{1 hr}$ , the answer is...

"It'll only take one hour to travel 40 miles. This is correct because the unit rate is $\frac{40 miles}{1 hr}$ . "

3. Knowing that the constant speed of the plane is $\frac{800 km}{1 hour\\}$ , we can scale then add half of the unit rate to get our answer.

$\frac{800 km}{1 hour\\}$ x 3 = $\frac{2400 km}{3 hrs}$ 800 x 3 = 2400

then add half of unit rate which is $\frac{400 km}{30 mins}$ $\sqrt[2]{800}$ = 400

so, our answer is $\frac{2800 km}{3.5 hours}$

4. $\frac{3km}{30 mins}$ <--- ( divided by 2) $\frac{6 km}{1 hr}$ ( multiplied x 2.5) ---> $\frac{15 km}{2.5 hrs}$

To get an easier way to find the answer, if possible you can scale back farther than the 1 hour mark.

Elmer would take 2 and a half hours to ride 15 km.

5. The boys speed is $\frac{4 km}{1 hr}$ . All we need to do is divide by 2. $\sqrt[2]{8}$ = 4

Softa [21]

Answer:

$(d)$ $H_o: p = 0.35$ $H_a: p > 0.35$

Step-by-step explanation:

Given

$\mu = 35\%$

Required

The hypothesis statements

First claim: 35% will support a strike.

This represents the null hypothesis

$H_o: p = 0.35$

Second claim: A greater percentage will support the strike.

This represents the alternate hypothesis

$H_a: p > 0.35$
