2.6Step-by-step explanation:
To solve this, we need to use the Pythagorean theorem to solve this.
The way to solve is by solving for AD by using triangle CAD and then using that result to solve for BD.
3.4² + b² = 6.5²
11.56 + b² = 42.25
42.25 - 11.56 = b²
b = √30.69
b = 5.53985559 or about 5.5
4.9² + b² = 5.5²
24.01 + b² = 30.69
30.69 - 24.01 = 6.68
b = √6.68
b = 2.58456959666 or about 2.6
EDIT: the other user is incorrect, here's why3.4 + 4.5 = 7.9
6.5² + 4.9² = 7.9²
66.26 doesn't equal 62.41

The Sweater Shack is offering a 20% discount on sweaters. If the regular price of a sweateris $15.00, what is the discount? /There are 30 students in Mrs. Jones class. Twenty percent of the students received an A on the last math test. How many students received an A? / Jean Junction is selling jeans at 15% off the regular price. The regular price is $25.00 per pair. What is the discount?/ if you can answer these Ill do another 100 points but please I really need help
Given that ,
The sweater shack is offering 20% discount,
and the regular price is $ 15 .00,
so, the discount given would be
⇢ $ 15 x 20/100
⇢$ 15 x 0.2
⇢$ 3
selling price⇢Regular price - Discount price
⇢$15 - $(20/100 x 15)
⇢$15 - $3
⇢$12
Answer 2↷Given that,
20% out of 30 students scored an A in previous math test,
so ,the number of students who got an A in the test
⇢ 30 x 20/100
⇢30 x 0.2
⇢6
Hence ,6 students secured an A grade in last math test
Answer 3↷Given that,
The Jean junction is selling the jeans at the discount rate of 15% of the regular price which is $25.00,
so, the discount is
⇢$25.00 x $ ( 15/100 )
⇢$25.00 x $ 0.15
⇢$3.75
selling price⇢ $25.00 - $25.00 x $ ( 15/100 )
⇢$25.00- $25.00 x $ 0.15
⇢$25.00 -$3.75
⇢$21.25

You and your friend join a new gym that requires a one-time joining fee and monthly payments. Your friend chooses the 1 year plan and pays $687, while you elect the 18 month contract which costs $981. Use this information to determine the linear model used to calculate cost from months of membership.
Answer:
C = 99 + 49m
x = $99
y = $49
Step-by-step explanation:
Let
x = one time joining fee
y = monthly payment
Your friend:
1 year = 12 months
x + 12y = $687
You:
x + 18y = $981
x + 12y = 687 (1)
x + 18y = 981 (2)
Subtract (1) from (2)
18y - 12y = 981 - 687
6y = 294
Divide both sides by 6
y = 294 /6
= 49
x = $49
Substitute y = 49 into
x + 12y = 687
x + 12(49) = 687
x + 588 = 687
x = 687 - 588
= 99
x = $99
C = 99 + 49m
Where,
C = total charges
m = number of months
99 = a one time joining fee
49 = charges per month

The length of Rectangle A is 5 inches more than its width. The perimeter of Rectangle B is 17. The difference between the perimeters of the rectangles is less than 9. What are the possible integer values for the width of Rectangle A?
Based on the perimeter value, the width of the rectangle is 1.75 inches
What are perimeters?The perimeter of a shape is the sum of the side lengths of the shape
For all regular quadrilaterals, you add up the side lengths to determine the perimeter
How to determine the width of the rectangle?The given parameters about the rectangle are
Perimeter = 17
Length = Width + 5
Rewrite the above equations as
l = w + 5
p = 17
The perimeter of a rectangle is
p = 2 x (l + w)
Substitute p = 17 in the above equation
So, we have
2 x (l + w) = 17
Substitute l = w+ 5 in the above equation
So, we have
2 x (w + 5 + w) = 17
Evaluate the like terms in the above equation
So, we have
2 x (2w + 5) = 17
Open the bracket in the above equation
So, we have
4w + 10 = 17
Evaluate the like terms in the above equation
So, we have
4w = 7
Divide both sides of the above equation by 4
So, we have
w = 1.75
Hence, the width of the rectangle is 1.75 inches

The local water supply has a leak, it is losing 4 gallons of water every second.
After 15 seconds, the water level is at 1024 gallons. Write an equation to
represent the situation: *
Answer:
An equation to represent the situation would be:
[tex]y = 4x + 964[/tex]Step-by-step explanation:
Given that the water supply is losing 4 gallons of water every second.
It means the rate of change = 4 gallons per second
Given that after 15 seconds, the water level is at 1024 gallons.So the equation becomes
1024 = 4(15) + b
comparing with the slope-intercept form of the equation of a line
[tex]y = mx+b[/tex]
where m is the slope (rate of change) and b is the y-intercept
so
[tex]1024 = 4(15) + b[/tex]
[tex]1024 = 60 + b[/tex]
[tex]1024 - 60 = b[/tex]
[tex]b = 964[/tex]
So, the value of y-intercept i.e b=964
Thus, the equation will be
[tex]y = mx+b[/tex]
substituting the value rate of change i.e m = 4 and b=964
[tex]y = 4x + 964[/tex]
Therefore, an equation to represent the situation would be:
[tex]y = 4x + 964[/tex]Ann and Ruth bowled together and had a combined score of 410 points. Ann's score was 44 points less than Ruth's score. Write a system of equations that can be used to determine x, Ann's score and y, Ruth's score.
Answer:
x=y-44 and x+y=410
Step-by-step explanation:
So, you want to use the equations x=y-44 and x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.

Answer:
The Distance from the center ( B ) of the smaller circle to its edge is the radius of the circle therefore length BD = length AB
From the given diagram
The center of the bigger circle is at C while
The center of the smaller circle is at point B .
The smaller circle cuts through the bigger circle creating two segments BD and AB which starts from the middle of the smaller circle to the intersecting edges of the circles.
Hence the length of segment BD = length of segment AB because they both start from point B .

Answer:
1/25
Step-by-step explanation:
We can see that in this pattern, the denominator and the numerator of the next fraction cancel out; they're the same.
(1/2) x (2/3) x (3/4) = 1/4 (do you see it?)
The only things that do not cancel out are the numerator of the first fraction and the denominator of the last. So, in the end, the answer will be 1/25.

350cm³ to 1 litre as a ratio in its lowest terms
We need to know about ratio to solve the problem. The ratio of 350[tex]cm^{3}[/tex] to 1 litre as a ratio in its lowest terms is 7:20.
Ratio is the measure of how many times one number contains another in it. We can find the ratio of one quantity to another by dividing one by the other by cancelling out the common factors between the two. We have to find the ratio of 350[tex]cm^{3}[/tex] to 1 litre in its lowest terms. The lowest terms for both the quantities is [tex]cm^{3}[/tex]. We know that 1 litre =1000[tex]cm^{3}[/tex], we will convert the 1 litre to 1000[tex]cm^{3}[/tex] for calculating the ratio.
The ratio of 350 [tex]cm^{3}[/tex] to 1 litre =350/1000=35/100=7/20= 7:20
Therefore we found the ratio of 350 [tex]cm^{3}[/tex] to 1 litre in its lowest terms to be 7:20 by using the concept of ratio.

Prove that the measure of angle JKL is 90 degrees.
∡ NKM + ∡KNM + ∡ NMK = 180° Because Angles in a triangle ΔNKM sum to 180°
∡ NKM + 90° + 60° = 180°
∡ NKM = 30°
∡ NKM = ∡JKN = ∡ MKL = 30° because ΔJKM∼ΔNKM∼ΔMKL
Finally:
∡ JKL = ∡ NKM + ∡JKN + ∡ MKL
∡ JKL = 30° + 30° + 30°
∡ JKL = 90°
With the help of properties of triangle ∠JKL = 90 degrees.
To prove:
∠JKL = 90 degrees.
Here,
Angle sum property of triangle:
In any triangle sum of angles is 180 degrees.
So,
In ΔNKM
∡ NKM + ∡KNM + ∡ NMK = 180°
∡ NKM + 90° + 60° = 180°
∡ NKM = 30°
Now,
ΔJKM∼ΔNKM∼ΔMKL (By AAA)
Thus,
∡ NKM = ∡JKN = ∡ MKL = 30°
Next,
∡ JKL = ∡ NKM + ∡JKN + ∡ MKL
∡ JKL = 30° + 30° + 30°
∡ JKL = 90°
Hence proved.
