Lisa and Marie are both on the track team. During practice, Lisa ran 10 laps around
the track in 18 minutes. Marie ran 8 laps around the track in 14 minutes. Who ran at a
faster rate? If each runner continues at her same pace, how long would it take each
one to run 15 laps?
Answer:
Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.
Step-by-step explanation:
18 ÷ 10 = 1.8 (Lisa's rate)
14 ÷ 8 = 1.75 (Marie's rate)
1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)
1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)
Write 125 as a repeated multiplication of 5s. Then write it as a power.

in the triangle find y (it’s geometry) i’ll give thanks
Answer and Step-by-step explanation:
We will use trig functions to solve for y.
This will be done using the sine trig function.
[tex]sin(y) = \frac{9}{17}[/tex]
Multiply [tex]sin^{-1}[/tex] to both sides, then use a calculator to solve.
[tex]y = sin^{-1} (\frac{9}{17} )[/tex]
y = 31.96571875
y ≈ 32 is the answer.

(I NEED HELP ASAP) Raven bought a TV originally priced at $225. She got a 22% discount. If she gave the cashier $200, how much change did she get back?
Answer:
She got $24.50 after paying for the tv.
Step-by-step explanation:
First, you want to find what the price was after the discount. So you want to multiply 225 by .22 to get the price.
225 x .22 = 49.5
After the discount, the price is off $49.50
Now you take 225 - 49.5 and that you give you $175.50
Next, you take 200 - 175.50 and that you give you 24.5
So, She got $24.50 after paying for the tv.

g1(1)=51
g(n)=g(n_1)+2
Answer:
[tex]g_n = 49+ 2n[/tex]
Step-by-step explanation:
Given
[tex]g_1=51[/tex]
[tex]g_n=g_{n-1}+2[/tex]
Required
Determine the explicit formula (missing from the question)
First, calculate g2
[tex]g_n=g_{n-1}+2[/tex]
[tex]g_2 = g_{2-1} +2[/tex]
[tex]g_2 = g_1 +2[/tex]
[tex]g_2 = 51 +2[/tex]
[tex]g_2 = 53[/tex]
So, we have:
[tex]g_1=51[/tex]
[tex]g_2 = 53[/tex]
Calculate the common difference:
[tex]d = g_2 - g_1[/tex]
[tex]d = 53 - 51[/tex]
[tex]d = 2[/tex]
The explicit formula is calculated using:
[tex]g_n = g_1 + (n-1)d[/tex]
This gives:
[tex]g_n = 51 + (n-1)*2[/tex]
[tex]g_n = 51 + 2n-2[/tex]
Collect Like Terms
[tex]g_n = 51 -2+ 2n[/tex]
[tex]g_n = 49+ 2n[/tex]

A certain animal gets food from another animal without killing it. Identify the type of organism.
(A) Saprophyte
(B) Carnivore
(C) Parasite
(D) Autotroph
Answer:
The correct answer is C. Parasite.
Step-by-step explanation:
Parasitism describes the phenomenon within the animal and plant world that an organism or virus (parasite) misuses a usually considerably larger organism of a different species as a host. The host serves the parasite for food supply (mostly in the form of blood or other body secretions) and in some cases also as a long-term habitat. The host's health is damaged by the parasite, but usually remains alive. The consequences of parasitic infestation range from sting or bite injuries from massive physical complaints to serious infectious diseases and even death in extreme cases. The best known and most widespread human parasites are human lice, mosquitoes and various types of ticks and worms.
