A rectangle has a length of √7 and a width of 3√8. Find the area of the rectangle.
The area of the rectangle is 3[tex]\sqrt{56}[/tex]
Given,
A rectangle has a length of √7 and a width of 3√8.
We need to find the area of the rectangle.
What is the area of a rectangle?The area is given by:
Area = Length x width
Find the length and width of a rectangle.
Length = [tex]\sqrt{7}[/tex]
Width = 3[tex]\sqrt{8}[/tex]
Find the area of the rectangle.
Area = Length x width
= [tex]\sqrt{7}[/tex] x 3[tex]\sqrt{8}[/tex]
When there are two different square roots we multiply them together under one root.
[tex]\sqrt{a\times b} ~~=~~\sqrt{a}\times\sqrt{b}[/tex]
Now,
= 3[tex]\sqrt{7\times8}[/tex]
= 3[tex]\sqrt{56}[/tex]
Thus the area of the rectangle is 3[tex]\sqrt{56}[/tex]

Solve. 2(2z – 4) = 4
Answer:
[tex]z = 3[/tex]
Step-by-step explanation:
1) Divide both sides by 2.
[tex]2z - 4 = \frac{4}{2} [/tex]
2) Simplify 4/2 to 2.
[tex]2z - 4 = 2[/tex]
3) Add 4 to both sides.
[tex]2z = 2 + 4[/tex]
4) Simplify 2 + 4 to 6.
[tex]2z = 6[/tex]
5) Divide both sides by 2.

log [tex]x^{n}[/tex] = nlog x
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]
Given

Q: Maya has 200 songs on her mobile device. Of these songs, 48 are jazz songs. What percent of Maya's songs are jazz songs?
To find the percentage of something, we can take the number that we want to find the percentage for divided by the total number of items.
In this problem, the number that we want to find the percentage for are the jazz songs, which is 48.
The total number of items is 200 songs.
Therefore, we can divide the number of jazz songs by the total number of songs in order to find the percentage of Maya's jazz songs.
# jazz songs/total # songs 48/200 = 0.24To convert a decimal to a percentage, we can move the decimal point two places to the right (aka multiply by 100).
0.24 → 24%24% of Maya's songs are jazz songs.

Answer:
x=128
Step-by-step explanation:
180-52=128
Answer: x= 128 degrees
Step-by-step explanation:
Angle “x” and angle with measure of 52 degrees are a linear pair.
Linear pairs sum to 180.
52+x=180. Subtract 52 from both sides.
X= 128
*OR you can use angles around a point sum to 360 degrees.
52+38+142+x = 360. Combine like terms.
232+x= 360. Subtract 232 from both sides.
X= 128

One-third of a number plus 2 is greater than 11. What are the possible values for ?
Answer:
The equation is 1/3x+2>11
Anything greater than 27 is a possible answer
Step-by-step explanation:
Step 1
Subtract 2 from both sides, 2-2 cancels out and 11-2=9
Now you have 1/3x>9
Step 2
Divide both sides by 1/3, 1/3 divided by 1/3 cancels outs and 9 divided by 1/3 is 27
Now you have x>27
So anything greater than 27 is a possible answer
You want $5000 4 years from nowfor a down payment for a car. How much money must be deposited monetly into an account earning 4.2% compounded monthly to achieve this goal?
Answer:
$95.5090 must be deposited monthly
Step-by-step explanation:
From the information given:
The annual interest rate (r) = 4.2% = 0.042
Let assume that an amount Y is deposited, then after one month, it will increase to:
[tex]Y ( 1+ \dfrac{0.042}{12})[/tex]
The total amount after 4 years will be:
[tex]= Y ( 1+ \dfrac{0.042}{12})^{48}+Y ( 1+ \dfrac{0.042}{12})^{47} +Y ( 1+ \dfrac{0.042}{12})^{46} +...+ Y ( 1+ \dfrac{0.042}{12})[/tex]
[tex]= Y ( 1.0035)^{48}+Y ( 1.0035)^{47} +Y( 1.0035)^{46} +...+ Y( 1.0035)[/tex]
Using the sum of a geometric progression:
[tex]= Y (1.0035) \dfrac{ (1.0035^{48}-1)}{(1.0035-1)}[/tex]
[tex]= Y (1.0035) \dfrac{ (1.0035^{48}-1)}{0.0035}[/tex]
The above amount is then equal to $5000
i.e
[tex]= Y (1.0035) \dfrac{ (1.0035^{48}-1)}{0.0035} = 5000[/tex]
[tex]Y = \dfrac{5000\times 0.0035}{(1.0035)(1.0035^{48}-1)} \\ \\ \mathbf{Y = \$95.5090}[/tex]
Prove \triangle ABE\cong\triangle ACE△ABE≅△ACE. Be sure to state any congruencies and the criteria used to determine them.
Answer:
The answer is below
Step-by-step explanation:
Two triangles are congruent if they have the same shape and their corresponding sides are equal to each other.
1) AB = DC, BE = CE (given)
2) ∠AEB≅∠DEC (vertical angles are congruent)
3) ΔABE ≅ ΔACE (side angle side congruence theorem)
If the two sides and an included angle of one triangle is equal to two sides and one included angle of another triangle, then the two triangles are congruent by SAS congruence theorem.
