Answer:
x=2
Step-by-step explanation:
25/625 is 1/25
1/25 = 1/5^x
1/5 =sqrt 1/25 and that is 2
so x=2.

Two S-year old girls, Alyse and Jocelyn, have been training to run a mile racc Alyse's I mile A is approximately Normally distributed with a mean of 13.5 minutes and a standard deviation of 2.5 minutes. Jocelyn's I mile time approximately Normally distributed with a mean of 12 minutes and a standard deviation of 1.5 minutes. Assuming A and J are independent random variables, what is the probability that Alyse has a smaller time than Jocelyn in a 1 sile race on a randomly selected day?
Answer:
Step-by-step explanation:
An airplane is flying from nyc to la. The distance it travels in miles,d, is related to the to the time in seconds, t, by the equation d=0.15t
Answer:
It will cover 4.5 miles in 30 seconds.
Step-by-step explanation:
An airplane is flying from nyc to la.
The distance it travels in miles,d, is related to the to the time in seconds, t, by the equation :
d=0.15t ...(1)
Let us assume we need to find the distance at t = 30 s.
Put t = 30 s in equation (1).
d=0.15 × 30
d = 4.5 miles
Hence, it will cover 4.5 miles in 30 seconds.
Hey I neee help with this I don’t understand for number 1 it’s w=? For number 2 it’s w=75 and for number 3 it’s w=26. Pls I need help it’s due in 10 minutes I’ll mark brainliest possibly.
Answer:
1. W = 50 ft
2. L = 110 m
3. L = 61 m
Step-by-step explanation:
Area of a Rectangle
Given a rectangle of width W and length L, its area is calculated by the formula:
A = W.L
We are given three rectangle-shaped figures and are required to find different measures as explained below.
1. Length L=94 ft, Area = 4,700 square ft
We'll find the width by solving for W:
[tex]\displaystyle W = \frac{A}{L}[/tex]
[tex]\displaystyle W = \frac{4,700}{94}[/tex]
W = 50 ft
2. A=8,250 square m, W=75 m
We'll find the length by solving for L:
[tex]\displaystyle L = \frac{A}{W}[/tex]
[tex]\displaystyle L = \frac{8,250}{75}[/tex]
L = 110 m
3. A=1,586 square m, W=26 m
We'll find the length by solving for L:
[tex]\displaystyle L = \frac{A}{W}[/tex]
[tex]\displaystyle L = \frac{1,586}{26}[/tex]
L = 61 m

A submarine hovers at 66 and two-thirds yards below sea level. If it ascends 24 and StartFraction 1 over 8 EndFraction yards and then descends 78 and three-fourths yards, what is the submarine's new position, in yards, with respect to sea level?
Answer:
- 121 7/24
Step-by-step explanation:
Initial Position = 66 2/3 below sea level
Ascent = 24 1/8
Descent = 78 3/4
New position of submarine :
Since initial. Position is below sea level, we finite with a negative sign :
-66 2/3 = - 200 /3
Ascent is positive ; 24 1/8 = 193 / 8
-200 /3 + 193 / 8
(-1600 + 579) / 24
= - 1021 / 24
Descent = 78 3/4 (negative) downward
78 3/4 = - 315/ 4
-1021 / 24 - 315/4
(-1021 - 1890) / 24
= - 2911 / 24
= - 121 7/24
121 7/24 below sea level
2. Two rectangular fields with identical shapes and areas are to be fenced side by side. The total area enclosed is 8mi^2 and the perimeter for all the fencing is 16 miles. Find the possible dimensions of one of the fields (2 possible answers).
Step-by-step explanation:
Let length is x and breadth is y.
The formula for the area and the perimeter of a rectangle is given by :
A = xy
P = 2(x+y)
Here, A = 8 mi² and P = 16 miles
Putting all the values,
xy = 8
y=8/x ......(1)
2(x+y) = 16
x+y = 8 .....(2)
Put equation (2) in equation (1) as follows :
[tex]x+\dfrac{8}{x}=8\\\\x^2+8=8x\\\\x^2-8x+8=0[/tex]
When we solve, we get :
x = 6.82 miles, 1.17 miles
Put the value of x in equation (1)
When x = 6.82 miles,
y = 8/6.82
y = 1.17 miles
When x = 1.17 miles,
y = 8/1.17
y = 6.82 miles
Hence, the dimension of the field is 6.82 miles and 1.17 miles.

Answer:
5a. ΔGKM ~ ΔSPM by SAS
b. ΔABC is not similar to ΔDEF
6. The missing side is 2[tex]\sqrt{11}[/tex]
Step-by-step explanation:
5a. Yes, the triangles are similar.
<KMG ≅ <PMS (vertically opposite angles)
ΔGKM ~ ΔSPM by SAS
Ratio: GM:SM OR KM:PM
3:6 OR 2:4
1:2 OR 1:2
Ratio: 1:2
b. No, the triangles are not similar
ΔABC is not similar to ΔDEF
Ratio: AC:DF OR AB:DE
4:6 OR 2:4.5
1:1.5 ≠ 1:2.25
Ratio: not similar
6. let the missing side of the triangle be represented by x. Since the triangle is a right angled triangle, then applying the Pythagoras theorem we have;
[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/12/^{2}[/tex] = [tex]x^{2}[/tex] + [tex]/10/^{2}[/tex]
144 = [tex]x^{2}[/tex] + 100
[tex]x^{2}[/tex] = 144 - 100
= 44
x = [tex]\sqrt{44}[/tex]
= [tex]\sqrt{4 *11}[/tex]
= 2[tex]\sqrt{11}[/tex]
x = 2[tex]\sqrt{11}[/tex]
The missing side is 2[tex]\sqrt{11}[/tex].

A wire is attached to a 425-foot tower that is perpendicular to the ground. The wire makes an angle of 26.5o to the ground. what is the length of the wire in feet
Answer
952.49feet
Step-by-step explanation:
This set up will be a right angled triangle
Height = opposite side = 425foot
Length of wire = hypotenuse= x
Angle of elevation= 26.5°
Using the SOH identity
Sin 26.5 = opp/hyp
Sin26.5 = 425/x
x = 425/sin26.5
x =425/0.4462
x = 952.49feet
Hence the length of the wire is 952.49feet

The change in the value of stock is represented by the rational number -5.90. Describe, in words, what this means.
Answer:
DEFINITION of Value Change
Value change is an adjustment made to a stock's price to reflect the number of outstanding stock shares issued and currently held by investors. A value change allows the group of stocks to be equally weighted and, therefore, more easily evaluated. Since the number of shares held by investors changes daily, this number can be updated daily to reflect the changes.

If there are 328 million people and 228 thousand become infected each day, how long will it take for all to be infected?
Answer:
1438.6 days
Step-by-step explanation:
We are told in the above question that:
228,000 people get infected per day. Hence, how long it would take for 328,000,000 people to be infected is calculated as:
228,000 people = 1 day
328,000,000 people = x days
Cross Multiply
228,000 people × x days = 328,000,000 people × 1 day
x days = 328,000,000 people × 1 day/228,000 people
x days = 1438.5964912 days
Approximately = 1438.6 days
Therefore, it would take 1438.6 days for 328,000,000 people to be infected.

What is JK? please explain/show your work on how you got your answer
Answer:
JK = 20 mStep-by-step explanation:
A line segment that connects two midpoints of the sides of a triangle is called a midsegment.A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side.Point J is midpoint of side HI as HJ = JI
Point K is midpoint of side GI as GK = KI
JK is midsegment as connects the midpoints of the sides
JK = 1/2HG as per property of midsegment
6x - 4 = 10x/26x - 4 = 5x6x - 5x = 4x = 4JK = 6x - 4 = 6*4 - 4 = 24 - 4 = 20 m
Answer:
[tex]JK=20m[/tex]
Step-by-step explanation:
It is given in the diagram that IJ = JH and IK = KG. Therefore, by the definition of a midpoint, we know that J and K are the midpoints of segments IH and IG respectively. Then, it can be concluded that JK is a midsegment by the definition of a midsegment. The Midsegment Theorem states that a midsegment connecting the midpoints of two sides of a triangle is parallel and half of the length of the third side. Thus, we know that JK is half of HG. Now, we can set up the following equation to solve for x:
[tex]JK = \frac{1}{2}HG\\6x-4=\frac{1}{2}(10x)[/tex]
Solving for x, we get:
[tex]6x-4=\frac{1}{2}(10x)\\6x-4=5x\\x-4=0\\x=4[/tex]
Therefore, [tex]JK = 6x - 4 = 6(4) - 4=24-4=20 m[/tex].
