Answer:
DE is 4 units long.
Step-by-step explanation:
These are the 30-60-90 triangle side relationships:
Short leg × 2 = hypotenuseShort leg × √3 = long legLong leg ÷ √3 = short legHypotenuse ÷ 2 = short legWe are given the long leg and need to find the short leg. As seen above, the relation ship between those sides is:
[tex]S*\sqrt{3}=L[/tex]
or:
[tex]L \div \sqrt3 =S[/tex]
Given the long leg, divide it by √3 to find the short leg.
[tex]4\sqrt3 \div \sqrt3 = 4[/tex]
The short leg is 4 units long.

Joe borrow $5000 in the bank at a rate of 7% simple interest per year how much interest is paid in two years
Answer:
$700
Step-by-step explanation:
First, multiply 5,000 times 7:
5,000 × 7 = 35,000
Since 7% is 0.07, move the decimal place in 35,000 two times:
35,000.
One number is 5 less than twice a number.if the sum of two numbers is 76 what is the smaller number ?
Answer:
the smaller number is 27.
Step-by-step explanation:
set two numbers are a and b
one number is less that twice of a number:
let's say a is 5 less than twice of b
so we have : a=2b-5
sum of the two numbers is 76: we have a+b=76
then we set up the system of equation[tex]\left \{ {{a=2b-5} \atop {a+b=76}} \right.[/tex]
substitude a = 2b - 5 into the second equation
we have,
2b - 5 + b = 76
3b - 5 = 76
3b = 81
b = 27
Since a + b = 76 so a = 49

if the perimeter of the blanket has to be at least 280 inches is there egnough room for all three of them to cuddle up under the blanket? ( she’s talking about her dogs)
Answer:
hope it helps
Step-by-step explanation:
angle < EDG = 90°
5x + 4x = 90
9x = 90
x = 90/9
x = 10°
which means
5x = 50°
4x = 40°
---------------------------
sice EF and DG are parallel lines
EHD = 40°
DHG is 90°
then HGD = 50°
-----------------------------------------
ED = 64 x2 (2 sides) = 128 inches
DG = 84 x2 (2 sides) = 168 inches
total perimeter = 128 + 168 = 296 inches
and yes. theres enough room for all 3 to cuddle

Answer:
4.9 = 490%
15.27% = .1527
Step-by-step explanation:
1. To convert a decimal into a percentage, you multiply the decimal by 100.
For example, if we convert the number 1.01 into a percentage by multiplying it by 100, we get 101%. When converting from percentage to decimal, you divide by 100.2. (Solving)
4.9:
[tex]4.9 * 100[/tex] [tex]49 * 10[/tex] [tex]490[/tex] 490%15.27%:
[tex]15.27/100[/tex] [tex]1.527/10[/tex] [tex].1527[/tex]Therefore, the answers are 490% and .1527.
Answer: 490% and .1527
Step-by-step explanation:
Decimal to percentage: move decimal place 2 spaces to the left
Percentage to decimal: move decimal 2 space to the right
Steven noticed that there were 72 lights on and 78 lights turned off. Enter the percent of the lights turned on.
The lights which were on was 48%.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
Given that there were 72 lights on, and 78 lights turned off.
We need to find the percent of the lights turned on.
So, percentage of something =
= number of thing / total number of the thing x 100%
Here, the number of thing = light on = 72
Total = 72 + 78 = 150
So, the percent of light on = 72 / 150 x 100% = 0.48 x 100%
= 48%
Hence the lights which were on was 48%.

3x + y + z = 6
3x - 2y + 2z = 14
3x + 3y - 3z = -6
Let's solve for x.
3x+y+z=6
Step 1: Add -y to both sides.
3x+y+z+−y=6+−y
3x+z=−y+6
Step 2: Add -z to both sides.
3x+z+−z=−y+6+−z
3x=−y−z+6
Step 3: Divide both sides by 3.
3x3
=−y−z+6/3
x=−1/3y+−1/3z+2
Dalco Manufacturing estimates that its weekly profit, P, in hundreds of dollars, can be approximated by the
formula P = -4x² + 8x + 3, where x is the number of units produced per week, in thousands.
How many units should the company produce per week to earn the maximum profit?
Find the maximum weekly profit.
a.
b.
P = -2x^2 + 8x + 2
for maximum P, dP/dx = 0
dP/dx = -4x + 8 = 0
4x = 8
x = 2
The company should produce 2,000 units per week to earn maximum profit.
Maximum profit = -2(2)^2 + 8(2) + 2 = -8 + 16 + 2 = 10
Therefore, the maximum weekly profit is $1,000.

8x - 10y = 4
x = 8
Answer:
y= 6
Step-by-step explanation:
First you substitute in the 8 for x. you then multiply 8 times 8 which equals 64. you subtract 64 from 4 and 64, since it would be the opposite of addition. you would then take the -10y=-60, and you would divide by negative 10 to get y by itself. since negative 60 divided by negative 10 is a positive 6, your answer would be y equals 6.
In the triangle below, which equation can be used to solve for x?
Answer:
4th option
Step-by-step explanation:
We require to find the 3rd angle in the triangle, that is
third angle = 180° - (75 + 50)° = 180° - 125° = 55°
Using the Sine rule in the triangle
[tex]\frac{x}{sin75}[/tex] = [tex]\frac{13}{sin55}[/tex] ( cross- multiply )
x × sin55° = 13 × sin75° ( divide both sides by sin55° )
x = [tex]\frac{13sin75}{sin55}[/tex]
