If Sally starts out with 10 seashells, and she gives away 4, that equation can be written as 10-4. When you subtract 4 from 10 you get 6 sea shells, which is how many Sally will be left with. I hope this helps! 10-4=6 shells

dimulka [17.4K]

Answer:

Height of tree = 15 ft

Step-by-step explanation:

Given:

Length of shadow (Base) = 8 ft

Length from the tip to top of the tree (Hypotenues) = 17 ft

Find:

Height of tree = ?

Computation:

Using Pythagoras theorem:

$Height\ of\ tree = \sqrt{Hypotenues^2 - base^2} \\\\Height\ of\ tree = \sqrt{17^2 - 8^2} \\\\Height\ of\ tree = \sqrt{289-64}\\\\Height\ of\ tree = \sqrt{225}\\\\ Height\ of\ tree =15$

Height of tree = 15 ft

500/25=100/y help me in this :(

kupik [55]

Answer:

$\boxed{\boxed{\sf 1 \ by \ 2 }}$

500/25 = 100/y

100/5 = 100/y

20 = 100/Y

200/1 = 100/Y

By cross multiplication

200 × Y = 100 × 1

Y = 100 /200

Y = 1/2

Banks provide a number of services including all of the following except __________.

olchik [2.2K]

Answer:

A. Payday Lending

Explanation:

Payday Lending is common for small lending companies and not banks. They assist clients who have a minimal amount of salary to borrow a small amount of money with a high interest. The amount of money he can borrow will depend on the amount of salary he receives per month. The client will not be required to give any form of collateral for the borrowed money, thus, the client is said to be high-risk. However, he will have to return the money over a short period of time with an interest rate that is high. Though it is easy to get a loan with this kind of service, you have to make sure that you are employed.

Banks prefer to offer loans to people who have a steady income and a certain amount of salary.

Write the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5. Include your work

STALIN [3.7K]

Paralell to 2x+y=-5
means it has same slope
means it is in form
2x+y=c where we have to find c
convert to slope intercept
minus 2x both sides

xint of 2
xint is where th eline crosses the x axis or where y=0, x=2

2(2)+0=c
2(2)=c
4=c

the equation is 2x+y=4
