Step-by-step explanation:
79 : 53
divide by 79 on both sides
[tex]1 : \frac{53}{79}[/tex]
[tex]n = \frac{53}{79}[/tex]
Answer: 1 : 1.49
Step-by-step explanation:
the starting Ratio was= 79 : 53
now its 1 : ?
The first number was divided by 79 so we divide the other number by 79.
1 : 53 is now

Answers
Answer:
i just stole your points thank you
Step-by-step explanation:
5 – 6w – 5 – 95 + 2w = –48w – 70
-6w + 2w + 48w = -70 -5 + 5 +95
44w = 25
w=25/44
You can run at a speed of 6 mph and swim at a speed of 3 mph and are located on the shore, 4 miles east of an island that is 1 mile north of the shoreline. How far should you run west to minimize the time needed to reach the island?
Answers
The distance to run to minimize the time needed to reach the island is
3.4 miles
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Let x = distance to run.
Remaining distance to the point that is closest to the island = (4 - x) miles.
The distance d to the point x from the island is
using the Pythagorean theorem:
d² = 1² +(4 - x)²
d² = 1 + 16 -8x + x²
d² = 17 - 8x + x²
d = √(x² - 8x + 17)
Total travel time.
= Times running + Time swimming.
Speed = Distance / Time
Time = Distance/Speed
Total time:
T = x/6 + d/3
T = x/6 +√(x² - 8x + 17)/3
Minimized time is when T' is zero.
T' = 0
1/6 + 1/3 x 1/{2(√(x² - 8x + 17)} x (2x - 8) = 0
1/6 + (2x - 8)/6√(x² - 8x + 17) = 0
Multiply 6 on both sides.
1 + (2x - 8)/√(x² - 8x + 17) = 0
√(x² - 8x + 17) + 2x - 8 = 0
√(x² - 8x + 17) = 8 - 2x
Square both sides.
(x² - 8x + 17) = (-(2x - 8))²
(x² - 8x + 17) = (2x - 8)²
x² - 8x + 17 = 4x² - 32x + 64
4x² - x² - 32x + 8x + 64 - 17 = 0
3x² - 24x + 47 = 0
Finding the roots of the quadratic equation.
We get,
x = 3.4 and 4.6
Thus,
The distance to run to minimize the time needed to reach the island is
3.4 miles

In right triangle EAD with right angle at A, AE=4 units, AB=BC=CD and the area of triangle ABE=6 sq units. What is the length of segment CE? Express your answer as a decimal to the nearest tenth.
Answers
Answer:
CE = 7.2
Step-by-step explanation:
Area = 1/2bh
6 = 1/2 (b)(4)
6 = 2b
3 = b b represent AB, so BC and CD is 3 unit also
Length of CE , you have a right triangle with a leg(AE) = 4 and and the other leg (AC) = 6 and the hypotenuse (CE) = x
The figure is a right triangle so you know that a² + b² = c²
4² + 6² = x²
16 + 36 = x²
52 = x²
[tex]\sqrt{52 }[/tex] = x
7.211 ≈ 7.2 = CE

Fred earns $45 mowing the lawn. He spends $5 on music and puts half of what's left in a savings account. He then gets another $5 for washing his neighbor's car.
First, write the expression that represents the number of dollars Fred keeps (and does not put in his savings account), and then simplify.
Answers
The total amount that Fred keeps (and does not put in his savings account) is $20
Total earnings of Fred = $45
Amount spent on music = $5
Amount remaining after spending on music = $40
Fred puts half of what's left in a savings account.
Total amount put in the savings account = 40/2
Total amount put in the savings account = $20

Polynomial 2 = 23m - 4m²
Polynomial 3 = 5m³ - 1
(m³+3m²-18m)+(23m-4m²)+(5m³-1)
When adding polynomials, you'll add like terms.

Scrooge invests $500. He found a bank that would pay him 4% interest, compounded monthly.
a) Type of exponential function.
b) Write a function to represent the situation.
c) If he deposits the whole $500 and does not deposit or withdraw any other amount, how much money would he have after 4 years?
Answers
The formula that can be used to determine the amount Scrooge would have in 4 years is: A(1 +r)^nm
A = Amount invested = $400
r = interest rate = 4/12 = 0,0333
n = number of years
m = number of compounding
$500(1.0333)^(12 x 4) = $586.60.

Given: D is the midpoint of AC, ED = FD, and angle EDA = angle FDC
Prove that: Triangle AED = Triangle CFD
Answers
Answer:
Step-by-step explanation:
Side-Angle-Side postulate (SAS)
There are ΔAED and ΔCFD triangles that are congruent due to the SAS congruence postulate.
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
As per the given question,
D is the midpoint of AC, ED = FD, and angle EDA = angle FDC
In ΔAED and ΔCFD,
Side DE = Side DF
m∠EDA = m∠FDC
Side AE= Side FC
According to SAS, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.
Thus, both triangles are congruent.
Hence, there are ΔAED and ΔCFD triangles that are congruent due to the SAS congruence postulate.

in what value of b makes y= 2x + b the same as y= 2x what does that value mean
Answers
Answer:
B = 0
Step-by-step explanation:
If you have y = 2x + b and are trying to get to y = 2x
Then just remove the B itself meaning it's value would be 0 so it is as if that variable was never in the actual equation.
Basing ourselves off of the formula "y = mx + b"
B = 0 would mean that the y-intercept of the line is 0
Answer:
0
Step-by-step explanation:
if y=2x and y=2x+b is the same then b must be 0.
