Answer:

Step-by-step explanation:

Alright, lets get started.

There are 6 different stages of Tina's bike ride.

First: When she starts, her speed continuous increases means graph goes up.

Second : After seeing the stop sign, she slows down and speed reached to zero.

Third : She waits at stop sign, so, there is zero speed for some time.

Fourth : She again starts but at lower speed than previous speed.

Fifth : She makes a ride with steady speed.

Sixth : She finally slow down her speed and ends to zero.

So, the answer is second graph.

Write a numerical expression for each verbal phrase.

Nookie1986 [14]

Answer:

Option B. 16-8

Step-by-step explanation:

Let

z ------> the number of apple left

x -----> the total number of apples

y -----> the number of apples sold

we know that

The numerical expression of the phrase " the number of apples left if eight out of the sixteen apples have been sold" is equal to subtract the number of apples sold from the total number of apples

z=x-y

we have

x=16 apples

y=8 apples

substitute

z=16-8

PLEASE HELP!!

sp2606 [1]

Standard form is just putting (in this case) variables in alphabetical order. First we simplify- 2x+4=4y would become 1/2x+1=y. This is already in standard form, as numbers w/o variables come at the end. simplifying the next one is more tricky. first you get a variable/number alone-
9-2x-2y=4x+3
9-2y=6x+3
6-2y=6x
1-1/3y=x
1=x+1/3y
3=x+y
x+y=3
sorry if I was wrong and not of any help, But I do believe this is correct.

The variables x and y have a proportional relationship, and y= 2/5 when x = 5/8

Archy [21]

Answer:

B. 16/25 x is the answer

Step-by-step explanation:

lets find the proportional relationship,

y = kx

2/5 = k * 5/8

k = (2/5) / (5/8)

k = 16/25

so if k, constant is 16/25

Please help with this one :/

Naddika [18.5K]

Answer:

6.3°

Step-by-step explanation:

$\because \: \pi^{c} = 180 \degree \\ \\ \therefore \: 1^{c} = \frac{180 \degree }{\pi} \\ \\ \therefore \: 0.11^{c} = \frac{180 \degree }{3.14} \times 0.11 \\ \\ \therefore \: 0.11^{c} = \frac{180 \degree }{314} \times 11 \\ \\ \therefore \: 0.11^{c} = \frac{1980 \degree }{314} \times 11 \\ \\ \therefore \: 0.11^{c} = 6.30573248\degree \\ \\ \huge \red{ \boxed{\therefore \: 0.11^{c} = 6.3\degree }} \\ \\$
