Bob drove at an average speed of 15km/h correct to the nearest unit. He drove for 3 hours, correct to the nearest hour. What is the lower bound for the distance he drove?
Answer:
45km
Step-by-step explanation:
Given data
Average Speed= 15km/h
Time = 3 hours
Required
The distance traveled
Speed= distance/time
Distance= speed*time
Distance= 15*3
Distance= 45km
Hence the lower bound of the distance is 45km

Answer:
Step-by-step explanation:
1).b). 2x - 3y > 5
For (2, 1),
2(2) - 3(1) > 5
1 > 5
False.
So the answer is NO.
c). For (6, 2),
2(6) - 3(2) > 5
12 - 6 > 5
6 > 5
True.
Therefore, the answer is YES.
2). a). 3y + x ≤ 12
For (3, -2),
3(-2) + 3 ≤ 12
-6 + 3 ≤ 12
-3 ≤ 12
True.
Therefore, answer is YES.
b). For (4, 6),
3(6) + 4 ≤ 12
18 + 4 ≤ 12
22 ≤ 12
False.
Therefore, answer is NO.
c). For (-1, -2),
3(-2) + (-1) ≤ 12
-6 - 1 ≤ 12
-7 ≤ 12
True.
Therefore, answer is YES.
3). a). y < 3x - 15
For (5, -3),
-3 < 3(5) - 15
-3 < 0
True.
Therefore, answer is YES.
b). For (7, 5),
5 < 3(7) - 5
5 < 21 - 5
5 < 16
True.
Therefore, answer is YES.
c). For (3, -5),

-10x + 5y = 10
x - 5y = -28
−10x+5y=10
x−5y=−28
Rewrite equations:
x−5y=−28
−10x+5y=10
Step: Solve:
x−5y=−28
x−5y+5y=−28+5y(Add 5y to both sides)
x=5y−28
Step: Substitute:
−10x+5y=10
−10(5y−28)+5y=10
−45y+280=10(Simplify both sides of the equation)
−45y+280+−280=10+−280(Add -280 to both sides)
−45y=−270
−45y
−45
=
−270
−45
(Divide both sides by -45)
y=6
Step: Substitute:
x=5y−28
x=(5)(6)−28
x=2(Simplify both sides of the equation)
Answer:
x=2 and y=6

Answer:
48,400 yd²
Step-by-step explanation:
(220+180)/2*260=52000
1/2(180)(60)=5400
So the total area is 52000+5400=57400
Basketball court=2400
Picnic area = 4200
Playground = 40x50 + 10x40=2400
2400+4200+2400=9000
57400-9000=48400

hich scenario best describes an object with a displacement of zero?
A train moves uphill as it travels in a straight path.
A person walks 2 miles north and 2 miles west.
A ball rolls from the top to the bottom of a hill.
A race car starts and ends at the same point on a track.
Answer: C. A Ball Rolls from top to the bottom of a Hill
Step-by-step explanation: In order for this to be a displacement of 0, we need a vector quantity, so we need to specify a magnitude and direction in order to fully characterize it. Unlike distance, which can only get larger on any path taken, displacement can be positive, negative, or zero. Displacement is zero when you start and end at the same spot.

Solve each equation.
1. 25 - 3x = 40
2. } (x – 10) = -4
Step-by-step explanation:
For no 1
25 - 3x = 40
- 3x = 40 - 25
- 3x = 15
- x = 15 / 3
Therefore x = - 5
Now for no. 2
1/3 ( x - 10) = - 4
( x - 10 ) = - 12
x = - 12 + 10
Therefore x = - 2

Answer:
7/10
Step-by-step explanation:
Answer: [tex]-\frac{7}{10}[/tex]
Step-by-step explanation:
Ordered pairs are written as (x,y)
The difference between the x coordinates is -10
The difference between the y coordinates is -7
Slope is written as [tex]\frac{rise}{run}[/tex]
So, the slope is [tex]-\frac{7}{10}[/tex]

En un triángulo rectángulo A es un ángulo agudo y Sen A = 4/5 ¿Cuál será el valor de Tan A?
Answer:
[tex]\displaystyle \tan A=\frac{4}{3}[/tex]
Step-by-step explanation:
Funciones Trigonométricas
La identidad principal en trigonometría es:
[tex]sen^2A+cos^2A=1[/tex]
Si sabemos que A es un ángulo agudo (que mide menos de 90°), su seno y coseno son positivos.
Dado que Sen A = 4/5, calculamos el coseno:
[tex]cos^2A=1-sen^2A[/tex]
Sustituyendo:
[tex]\displaystyle cos^2A=1-\left(\frac{4}{5}\right)^2[/tex]
[tex]\displaystyle cos^2A=1-\frac{16}{25}[/tex]
[tex]\displaystyle cos^2A=\frac{25-16}{25}[/tex]
[tex]\displaystyle cos^2A=\frac{9}{25}[/tex]
Tomando raíz cuadrada:
[tex]\displaystyle cos\ A=\sqrt{\frac{9}{25}}=\frac{3}{5}[/tex]
La tangente se define como:
[tex]\displaystyle \tan A=\frac{sen\ A}{cos\ A}[/tex]
Substituyendo:
[tex]\displaystyle \tan A=\frac{\frac{4}{5}}{\frac{3}{5}}[/tex]
[tex]\displaystyle \tan A=\frac{4}{3}[/tex]

Answer:
Step-by-step explanation:
A printer takes two and one half seconds to print a flyer it took 75 seconds to print a batch of flyers without stopping how many flyers were printed with a multiplication and division equation and solve?
From the above question:
2 1/2 seconds = 1 flyer
75 seconds = x flyer
Cross Multiply
2 1/2 seconds × x flyer = 75 seconds × 1 flyer
