Answer:
1.h=7; 2. A=78.5; 3. h=3; 4. h=8; 5. I=5.
Step-by-step explanation:
1. A = bh for h, if b = 4 and A = 28
So 28=4h then we divided both side by 4 to get the value of h , h=7.
2. A = πr2 for A, if r = 5.
So A=3.14×25=78.5.
3. A = bh for h if b = 15 and A = 45. h=?
So 45=15h then we divided both side by 15 to get the value of h , h=3.
4. A = bh for h if b = 10 and A = 80. h=?
So 80=10h then we divided both side by 10 to get the value of h , h=8.
5.P = 2l + 2w for l if w = 4 and P = 18. l=?
So 18=2I + 2(4) =18-8=2I 10=2l then to get the value of I divided both side by 2, I=5.

Perpendicular lines are lines that intersect at a 90-degree angle. So, for example, line ST is perpendicular to line CD. So line ST is perpendicular to line CD.
Perpendicular lines always intersect each other, however, all intersecting lines are not always perpendicular to each other. The two main properties of perpendicular lines are: Perpendicular lines always meet or intersect each other. The angle between any two perpendicular lines is always equal to 90.
Given that
line m and n are perpendiculars
then angle ∠a = ∠b
then
5x + 20 = 7x -4
7x -5x = 20 + 4
2x = 24
x = 24/ 2
x = 12.
Hence the value of x = 12

4x - 2x + x - 6 = 15
solve for x and show steps!
Answer:
x = 7
Step-by-step explanation:
Let's solve the problem,
→ 4x - 2x + x - 6 = 15
→ 3x - 6 = 15
→ 3x = 15 + 6
→ x = 21/3

4. Technology required. Priya starts with $50 in her bank account. She then deposits $20
each week for 12 weeks.
a. Write an equation that represents the relationship between the dollar amount
in her bank account and the number of weeks of saving.
d=50+20w
b. Graph your equation using graphing technology. Mark the point on the graph
that represents the amount after 3 weeks.
The equation [tex]d=50+20w[/tex] represents the relationship between dollar amount in her bank account and the number of weeks of savings.
The definition of an equation is a formula that states that two formulas are equal. For example, 3x + 5 = 14 is an equation where 3x + 5 and 14 are two terms separated by an equal sign. The most basic and simple algebraic equations consist of one or more variables in mathematics. In mathematics, a graph can be defined as a graphical representation or chart that systematically represents data or values. A point on a graph often represents a relationship between two or more things.
(a) It is given that amount in bank account is $50 , amount deposited by Priya is $20 and time period is 12 weeks .
Let " d " be the dollar and " w " be the weeks
Multiply the number of weeks w by 20 to get the total savings and add up how much money she had in the account initially.
Money deposit by Priya in 1 week = $20
Money deposit by Priya in 1 week = [tex]20\times w[/tex]
Therefore , the equation will be [tex]d=50+20w[/tex]
(b) Graph of given equation is given below :
Let " w " represents the x - axis and " d " represents the y - axis
For 1 week , amount will be [tex]d=50+20=60[/tex]
For 2 week , amount will be [tex]d=50+20(2)=90[/tex]
For 3 week , amount will be [tex]d=50+20(3) = 110[/tex]

Marcy walked 3 7/10 miles on Saturday and Sunday she walked 0.25 more miles than she did on Saturday how many total miles did she walk over the weekend. Pls.
Help
It’s math
B
Over the weekend she walked a total distance of (4 + 5/8) miles
How many total miles did she walk over the weekend?
We know that on Saturday she walked a total of (3 + 7/10) miles (so we need to work with mixed numbers), and on Sunday she walked 0.25 of that distance.
Then the distance that she walked on Sunday is:
D = 0.25*(3 + 7/10) miles
We can rewrite: 0.25 = 1/4
replacing that:
D = (1/4)*(3 + 7/10) mi = (3/4 + 7/40) mi
= (30/40 + 7/40)mi = (37/40)mi
Then the total distance that she walked over the weekend is:
d = (3 + 7/10) mi + (37/40)mi
= (120/40 + 28/40) mi + (37/40) mi
= (185/40)mi = (160/40 + 25/40) mi = (4 + 5/8) mi

The value of x of the first rectangular deck is 8.
For given question,
The perimeter of a one rectangular deck is 78 feet.
The length of the first rectangular deck is represented as (2x + 3), and its width is represented as (3x-4).
Similarly, the perimeter of a second rectangular deck is 2 times the perimeter of the first deck with a length of (4x + 6) and a width of (6x -1).
We need to find the value of x of the first rectangular deck.
Let P1 be the perimeter of the first rectangular deck.
⇒ P1 = 2 × (length + width)
⇒ 78 = 2 × [(2x + 3) + (3x - 4)]
⇒ 39 = (2x + 3x + 3 - 4)
⇒ 39 = 5x - 1
⇒ 40 = 5x
⇒ x = 40/5
⇒ x = 8
Therefore, the value of x of the first rectangular deck is 8.

You are 5 feet 4 inches tall and cast a shadow 3 feet long. At the same time, a nearby water tower casts a shadow 74 feet 3 inches long.
a. Find the height of the water tower.
The height of the water tower is 132 feet
How to solve for the height of the towerWe have the height to be 5 feet 4 inches
then 1 feet = 12 inches
inch = 1 / 12 ft
Then 4 inches = 1 / 12 x 4
= 1 / 3 ft
Height = 5 1/3
= 16 / 3
height of the shadow cast = 3 feet
For the water tank
74 ft 3 inches
= 74 x 3 / 12
297 / 4
the height of the tower
[tex]\frac{height of person}{height of shadow} =\frac{height of tower}{height of person}[/tex]
= [tex]\frac{16/3}{3} =\frac{x}{297/4} \\\\\frac{16}{3*3} =\frac{4x}{297}[/tex]
