Last year the depth of the river was 4.2 feet deep. This year it dropped 7%. Find the depth of the river this year to cross it.
Answer:
7/100 × 4.2 = 0.294ft
(find 7% of 4.2 ft)
4.2-0.294= 3.91 ft
(subtract 7% from 4.2ft)
FINAL ANSWER: depth of river this year is 3.91 ft

Area of circle A
[tex]\pi \times {r}^{2} = area \: of \: a \: circle \\ \pi = 3.14 \\ 3.14 \times {8}^{2} \\ 3.14 \times 64 = 200.96 \: {cm}^{2} [/tex]
Area of circle B
[tex]\pi\times 4 (because \: radius \: is \: the \: half \: of \: diameter) \\ 3.14 \times 4 square = 50.24\: {cm}^{2} [/tex]
How many times larger is the area of circle A than circle B
[tex]200.96 \div 50.24 = 4[/tex]
therefore circle A is 4 times larger than circle B in accordance with its area

9. Write the equation of the line that is parallel to the line 5x - 4y = 4 and passes through the
point (-8, 2).
Answer:
y = 5/4x + 12
Step-by-step explanation:
4y = 5x - 4
y = 5/4x - 1
2 = 5/4(-8) + b
2 = -10 + b
b = 12
The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour. If
the depth after 6 hours of draining is 8 feet then write an equation for the water depth, d, as a function of the
amount of time it's been draining, t, in hours.
The linear function for the depth of water after t hours is given by:
[tex]d(t) = 17 - 1.5t[/tex]
The format of a linear function is given as follows:
[tex]d(t) = d(0) - at[/tex]
In which:
d(0) is the y-intercept, which is the initial value.a is the slope, which is the rate of change.The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour, which means that [tex]a = -1.75[/tex], thus:
[tex]d(t) = d(0) - 1.5t[/tex]
The depth after 6 hours of draining is 8 feet, which means that when [tex]t = 6, d(t) = 8[/tex]. This is used to find d(0).
[tex]d(t) = d(0) - 1.5t[/tex]
[tex]8 = d(0) - 1.5(6)[/tex]
[tex]d(0) = 17[/tex]
Then
[tex]d(t) = 17 - 1.5t[/tex]

Robert spends $30.45 before tax at the bookstore. If the sales tax rate in his city is 7.25%, what is the total cost of his purchase?
Answer:
32.65
Step-by-step explanation:
Answer:
Total cost of purchase = $32.66
Step-by-step explanation:
$30.45 before tax
If sales tax = 7.25% or 0.0725, then: $30.45 × 0.0725 = $2.21
Add the sales tax of $2.21 to $30.45 = $32.657 or $32.66
Therefore, the total cost of his purchase is $32.66

please help! Complete the function for this graph.
Answer:
y = - 2|x - (-2)| + 1
Step-by-step explanation:
The general form of an absolute value function is y = a|x – h| + k, where a ≠ 0.
The value of a determines whether the graph opens up or down. If a is negative, the graph opens down. This holds true, as the value of a = -2
The given graph for the absolute function has a vertex (h, k) of (-2, 1). This is the maximum point of the graph.
Therefore, the missing values on the given equation is the value of the vertex. It has to be written as y = - 2|x - (-2)| + 1 because the equation on your given problem is formatted according to the general form of the absolute value function, y = a|x – h| + k.

The length of a rectangular sign is 5 times its width. If the sign’s perimeter is 24 inches, what is the sign’s area The sign's area is ___ square inches.
The sign's area is 80 square inches.
A rectangle is a quadrilateral. This means that a rectangle has four sides.
The area of a rectangle = length x width
Perimeter of a rectangle = 2 x ( length + width)
Let the width of the sign be represented with w
The length of the sign is 5x
Substitute these dimensions into the formula for the perimeter of a rectangle.
(x + 5x) = 24
6x = 24
x = 24/6
x = 4 inches
The length is 5 x 4 = 20 inches
Area of the sign = 20 x 4 = 80 inches²

Graph by using the slope and the y intercept.
1. a) equation of the line :
[tex]y = \dfrac{2}{5}x - 7[/tex]y - intercept = -7
so, it will pass through point (0, -7)
and if we plug the value of x as 5, we get
[tex]y = (\dfrac{2}{5} \times 5) - 7[/tex][tex]y = 2 - 7[/tex][tex] = - 5[/tex]so, it will pass through point (5, -5) too
now, just plot the points (0 , -7) and (5 , -5) and join them.
2. b) equation of line is :
[tex]y = - 3x + 5[/tex]here, y - intercept = 5
so the line passes through point (0 , 5)
now, Plugging the value of x = 1 we get :
[tex]y =( - 3 \times 1) + 5[/tex][tex]y = - 3 + 5[/tex][tex]y = 2[/tex]so, the given line passes through point (1 , 2)
plotting the points, we can get our required line.

work out the value of x. 3x? x?
Answer:
x = 67.5
Step-by-step explanation:
Exterior angles always add up to 360 degrees. We have a defined right angle which takes 90 off of our 360, giving us 270 degrees. If we have x as an individual angle and also as x 3 times, then x is appearing 4 times. To find x, we divide our 270 degrees by 4 to get 67.5 . We can check this using a reversive property by multiplying 67.5 by 4 and then adding 90.
360 - 90 = 270
270 / 4 = 67.5
67.5 = x
