I thought of a 2-digit number. It's a multiple of 9 and the sum of its digits is five times smaller than the number itself. What is my number?
Step-by-step explanation:
Since the sum of the digits must be an integer, the number itself must also be a multiple of 5.
Lowest common multiple of 5 and 9 = 45.
Therefore the number could be 45 or 90.
5(9 + 0) =/= 90, so 90 is incorrect.
Since 5(4 + 5) = 45, 45 is the answer.
Answer: 45
Step-by-step explanation:
We know that it has to be a 2-digit number. Its the multiple of 9. We see there is a number in the question. Five. I simply took 9 and multiplied it by 5 which gave me a total of 45.
7x-6y=9
5x+2y=19 Solve the system using elimination.
Step-by-step explanation:
multiply 5x+2y=19 by 3 youll get 15x+6y=57
eliminate y
7x-6y=9
15x+6y=57 +
22x=66
x=3
substitute x to 5x+2y=19
15+2y=19
2y=4
y=2

Find the area of the shape.
Answer:
39.5 [tex]ft^{2}[/tex]
Step-by-step explanation:
We need to take this shape by shape
Top triangle
a = b*h/2
a = 3*2/2
a = 6/2
a = 3
__________________________________________________________
Bottom triangle:
a = b*h/2
a = 3*3/2
a = 9/2
a = 4.5
__________________________________________________________
Rectangle:
a = b*h
a = 8*4
a = 32
__________________________________________________________
Now add them all up
3 + 4.5 + 32 = 39.5
The area of the shape is 39.5 [tex]ft^{2}[/tex]

2. calculate the value of c
please help
Answer:
[tex] {c}^{2} = {a}^{2} + {b}^{2} \\ {c}^{2} = ({7 \sqrt{2}) }^{2} + ( {7 \sqrt{2} ) }^{2} \\ {c}^{2} = 2(49 \times 2) \\ {c}^{2} = 196 \\ c = \sqrt{196} \\ c = 13 \: units[/tex]
Find the values or a and b
Answer:
a=33 ( vertically opposite angles)
a+90=b( sum of opposite interior angle is equal exterior angle)
33+90 = b

Four friends took a road trip that lasted 50 hours round trip. Denny drove five times as long as Connor, while Pat and Seth drove the same amount of time. Connor drove half as long as Pat. How long did Denny drive?
Answer:
Denny drove for 25 hours
Step-by-step explanation:
Here, we want to calculate the amount of time Denny drove
Let the time Connor drove be c
Denny drove 5 times as this which is 5 * c = 5c
Conor drove half as long as Pat
So this means that Pat drove 2 times Conor = 2c
Seth is same as Pat which is also 2c
Adding all gives 50
c + 5c + 2c + 2c = 50
10c = 50
c = 50/10
c = 5 hours
Denny = 5 * c
= 5 * 5 = 25 hours

A traffic engineer records a sample of the types of vehicles that cross a bridge. She counts 112 passenger cars, 18 light trucks, and 20 heavy trucks.
What is the APPROXIMATE probability that a random vehicle crossing the bridge is a passenger car?
Answer:
The approximate probability that a random vehicle is a passenger car is 74.67%
Step-by-step explanation:
Probability
The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.
We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:
[tex]\displaystyle p=\frac{112}{150}[/tex]
p = 0.7467
p = 74.67%
The approximate probability that a random vehicle is a passenger car is 74.67%

A. 9
B. 8
C. 7
D. 6
Answer:
C
Step-by-step explanation:
The 2 triangles are similar (AA postulate ), thus the ratios of corresponding sides are equal, that is
[tex]\frac{14}{2}[/tex] = [tex]\frac{49}{x}[/tex] ( cross- multiply )
14x = 98 ( divide both sides by 14 )
x = 7 → C
