What is the ratio of the corresponding side lengths?
4:9
4:2
26:26
4.5:2
Answer:
4:2
Step-by-step explanation:
Answer:
4 : 2
Step-by-step explanation:
We are given ΔABC ≅ ΔA'B'C'.
When two triangles are congruent, their corresponding sides and angles are congruent.
Since, the sides of the triangles are in relation,
AB = 2 × A'B' and side BC = 2 × B'C' i.e. 4 = 2 × 2 and 9 = 2 × 4.5.
Therefore, the ratio of the corresponding sides are given by 4 : 2 and 9 : 4.5 i.e. 2 : 1.
Since, the ratio of the corresponding sides comes out to be 2 : 1 = 4 : 2.
Hence, the ratio of the corresponding sides is 4 : 2.

Your grandparents give you $1000 for your tenth birthday to invest for your college education. You research some investment companies around town and find one that pays you 4.2% and compounds quarterly. If you leave the money in your account until your 18th birthday, how much money will you have? Show all your work.
Answer:
$ 13,968.90
Step-by-step explanation:
You are given the money at 10 years oldInvest it until you're 18, so that's 8 yearsThis is compound interest, so use the formula: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]A is the total amount with interestP is the principal or starting amount 10000 dollarsr is the rate (percentage): 4.2%, use the decimal form in the equationn is the number of times you are compounding; in this case, it is compounded quarterly. Quarterly means every quarter of a year or 3 months, so it is compounded 4 times a year, n is 4t is the time, so that's 8 years[tex]A=10000(1+\frac{0.042}{4})^{4\times8}= 13,968.90[/tex]If a 6-ounce bottle of salad dressing costs $3.99, what is the cost per ounce?

14. Define a Variable
Answer: In mathematics, a variable is a symbol which functions as a placeholder for varying expression or quantities, and is often used to represent an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions
Step-by-step explanation:A symbol for a value we don't know yet. It is usually a letter like x or y.
Example: in x + 2 = 6, x is the variable.
Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.
The literal numbers like- x,y,z etc. are variables.
Eg - 4x - 7 = 5
Here in this example x is the variable.

FIND WHAT DID I DO WRONG
(-2)(-3)(-4)=(-6)(-4)=24
Answer:
It should look like this (-2)(-3)(4) = (-6)(-4) = 24
Step-by-step explanation:
You have to change the first -4 into a positive 4.
LOOK WHT YOU DID
(-2)(-3) = 6(-4) = -24
THE CORRECT WAY
(-2)(-3) = 6(4) = 24
So the equation should look like this (-2)(-3)(4) = (-6)(-4) = 24
See you only did one thing that's okay everyone makes mistakes!
