The spy will cover a distance of 60t in t hours and the special agent will cover a distance of 90t in t hours.
What is distance?Distance is actually known as the amount of space between two points. When calculating speed, it is given as:
Speed = distance ÷ time
The spy's distance in t hours:
Distance = 60 × t = 60t.
The special agent's distance in t hours:
Distance = 90 × t = 90t
The distance between them will be =
Distance of special agent minus distance of the spy: 90t - 60t = 30t.
By the time the chase begins, the distance between the spy and special agent will be:
(2 × 60mph) - 0 = 120m - 0.
= 120m.
Time taken for the special agent to catch the spy: 120 + 60t = 90t
120 = 90t - 60t
120 = 30t
t = 120/30 = 4 hours.
Speed the special agent should chase the spy:
Distance = 240 miles
Time = 4 hours.
Then Speed = 240/4 = 60mph.

Jamie needs to lease a car. At Big City Nissan, Jamie can lease an Altima for $3,000 down plus $420 per month. Big City will also give her the first two months of her lease free. At Rye Town Nissan, they offer her the same car for $3960 down plus $400 per month. Rye Town will give her the first four months free. After how many months would both deals cost the same?
Answer:
90 months
Step-by-step explanation:
Let x = number of months
Let y = total cost of deal
Big City Nissan
y = 3000 + 420x - 840
⇒ y = 2160 + 420x
Rye Town
y = 3960 + 400x
Equate the equations and solve for x
2160 + 420x = 3960 + 400x
⇒ 420x - 400 x= 3960 - 2160
⇒ 20x = 1800
⇒ x = 90
Find the values of x and y
x=
and
y=
Answer:
x = 61
y = 29
Step-by-step explanation:
The angle with the measure of 58 degrees and the angle represented by 2x are supplementary because they form a straight line.
2x + 58 = 180 subtract 58 from both sides
2x = 122 divide both sides by 2
x = 61
The angle represented by 2x and the angle represented by 58 are corresponding and their measure is equal to each other
2y = 58 divide both sides by 2
y = 29
What is the area of the quadrilateral
Answer:
Or you could also find the area of 2 triangles and one rectangle.
Area of a triangle = bh/2
1st triangle = 6 x 2 = 12
12 ÷2 = 6
2nd triangle = 6x2= 12 ÷ 2 = 6
Area of a rectangle
A=bh
b = 4
h= 6
6x4=24
Now add all the areas to find out the area of the shape, so
6+6+24 =

Find the distance between (1, 1) and (3, 4).
Answer:
√13
Step-by-step explanation:
Let,
( x1, y1 ) = ( 1, 1 )
Here,
x1 = y1 = 1
( x2, y2 ) = ( 3, 4 )
Here,
x2 = 3
y2 = 4
Formula : -
( Distance )² = ( x2 - x1 )² + ( y2 - y1 )²
( Distance )² = ( 3 - 1 )² + ( 4 - 1 )²
= 2² + 3²
= 4 + 9
( Distance )² = 13
Distance = √13

B and C are wrong
B: 7.89 x 10^-4
C: 3.15 x 10^2
Step-by-step explanation:
B is not written correctly. The purpose of scientific notation is to get rid of the decimal places with 0s. So instead of 0.789, it should be 7.89 x 10^-4
C is wrong, it should be 3.15 x 10^2
A circular flower bed is 24m in diameter and has a circular sidewalk around it that is 2m wide. Find the area of the sidewalk in square meters. Use 3.14 for pie (round to nearest 10th)
Answer:
163.3m²
Step-by-step explanation:
area = Pi(r²)
r = d / 2
r = 12
12² = 144
144 x 3.14 = 452.16
diameter of bigger circle = 24 + 4 (2 on each side)
28 / 2 = 14
14² = 196
196 x 3.14 = 615.44
sidewalk = bigger - smaller
sidewalk = 615.44 - 452.16
sidewalk = 163.3

show that the point (7,1) lies on the perpendicular bisector of the line joining (2,4) and (4,6)
Answer: True
Step-by-step explanation:
Let the point (7, 1) be Point A
Let the perpendicular bisector of the line joining (2,4) and (4,6) be Line PQ; P(2, 4) and Q(4, 6)
If A (7,1) lies on perpendicular bisector of P(2,4) and Q (4, – 6), then AP=AQ
[tex]\begin{aligned}\therefore \quad A P &=\sqrt{\left(2-7\right)^2+\left(4-1\right)^2}\:\\&=\sqrt{5^2+3^2}\\&=\sqrt{25+9}=\sqrt{34} \\\mathrm{and} \ \ \ A &=\sqrt{\left(4-7\right)^2+\left(6-1\right)^2}\: \\&=\sqrt{3^2+5^2} \\&=\sqrt{9+25}=\sqrt{34}\end{aligned}[/tex]

To control pollination, pollen-producing flowers are often removed from the top of corn in a process called detasseling. The hourly rates for detasselers in Iowa are roughly normally distributed, with a mean of $12/hr and a standard deviation of $2/hr. What are the z-scores for a detasseler making $13 and $17 an hour? z13 = 0. 9, z17 = 1. 25 z13 = 0. 5, z17 = 1. 25 z13 = 0. 5, z17 = 2. 5.
The z-scores for a deta seller making $13 and $17 an hour will be [tex]Z_{13}=0.5 \ \ \ Z_{17}=2.5[/tex]
What is z- value ?The z-scores give us information about how many standard deviations from the mean the data are. This difference can be negative, if the data are n deviations to the left of the mean, or it can be positive if the data are n deviations to the right of the mean.
To calculate the Z scores, we calculate the difference between the value of the data and the mean and then divide this difference by the standard deviation.
[tex]Z=\dfrac{X-\mu}{\sigma}[/tex]
Where x is the value of the data, μ is the mean and σ is the standard deviation
In this case :
μ = 12 $/h
[tex]\sigma[/tex] = 2 $/h
We need to calculate the Z-scores for x=17 and x=13
[tex]Z_{13}=\dfrac{13-12}{2}=0.5[/tex]
[tex]Z_{17}=\dfrac{17-12}{2}=2.5[/tex]
Thus the z-scores for a deta seller making $13 and $17 an hour will be [tex]Z_{13}=0.5 \ \ \ Z_{17}=2.5[/tex]

use the intersect method to solve the equation
-2x+1=-x^2+4
The intersect method involves spliting an equation to a system of equations
The solutions to the equation are (-1, 3) and (3,-5)
How to solve the equation?The equation is given as:
-2x + 1 = -x^2 + 4
Using the intersect method, we have the following equations
y = -2x + 1
y = -x^2 + 4
Next, we plot the graph of both equations
From the graph (see attachment), we have the following points of intersection
(x,y) = (-1, 3) and (3,-5)
Hence, the solutions to the equation are (-1, 3) and (3,-5)

royalred just started production of a new synthetic motor oil they have overhead costs of $21,804.00 a month plus manufacturing costs of $4.99 per quart of oil the oil sells for $7.36 per quart and the company's profit per month can be determined by the function p(x)=2.37x-21,804, where x is the number of quarts of oil sold over which of the following intervals will the company be making a profit
a: 2,962, 10,580
b: 9,201, 18,860
c: 2,932, infinite
d: 9,200, infinite
Considering the given profit function, it is found that the interval of values of x for which the company makes a profit is:
d: 9,200, infinite.
What is the profit function?Considering x as he number of quarts of oil sold, the monthly profit function is given by:
p(x) = 2.37x + 21,804.
The company makes a profit if p(x) > 0, hence:
p(x) > 0
2.37x + 21,804 > 0
x > 21,804/2.37
x > 9,200.

What is word problem?Word problem in mathematics is the use of critical understanding of the problem which then employs basic arithmetic operations, fractions, ratios, algebraic expression, etc to solve real-life problems.
From the parameters given:
Debbie has = 65 tubs of yogurtThe boxes of granola = 16The number of kids that consume the same quantity of both food types = 4The time at which the 65 tubs of yogurt will finish:
= 65/4
= 16th rounds with a remainder of 1 tub
The time at which 16 boxes of granola will finish:
= 16/4
= 4th round
A tub of yogurt is roughly 17 ounces while a box of granola is 1 ounce.
