What is the area of the triangle?
48 in 2
28 in 2
96 in 2
24 in 2
Answer:
48 in^2
Step-by-step explanation:
To find the area of a triangle is (1/2)*base*height, so (1/2)*4in*24in = 2in*24in = 48 in^2.
Answer:
48 in2
Step-by-step explanation:
when finding area we use the equation A= 1/2bh
b meaning base and h meaning height
so for this we would use A= 1/2(24)(4)
multiply them both to get A=1/2(96)
and then take half of 96 to get 48
so the answer is 48in 2

18 vocabulary words learned in 2 hours; 27 vocabulary words learned in 3 hours
Answer: They are equivalent
Step-by-step explanation:
Here is the complete question:
18 vocabulary words learbed in 2 hours 27 vocabulary words learned in 3 hours Are they equivalent? Why
From the question, we are informed that 18 vocabulary words are learned in 2 hours. The number of words learned per hour will be:
= 18/2
= 9 words per hour.
27 vocabulary words learned in 3 hours. The number of words learned per hour will be:
= 27/3
= 9 words per hour.
Since they both have identical number of words learned per hour, it means that they're equivalent.

Alex was biking along a 48 mile trail. First half of the time he was biking twice as fast as the second half of the time. If he spent 4 hours on the road, how fast was he biking at first?
Answer:
The speed in the first part is 16 mph.
Step by step explanation:
The total distance is 48 miles. The total time is 4 hours.
In the second part of the trip, he was traveling at speed s for distance d for 2 hours.
In the first part of the trip he was traveling
at twice the speed, or 2s, for distance 48 - d, for 2 hours.
speed = distance/time
distance = speed * time
First part of trip:
48 - d = 2s * 2
d + 4s = 48 Equation 1
Second part of the trip:
d = s * 2
d = 2s =
Equation 2
Equations 1 and 2 form a system of equations in two unknowns, d and s.
d + 4s = 48
d = 2s
Substitute 2s for d in equation 1.
2s + 4s = 48
6s = 48 =
s=8
The speed in the second part is 8 mph.
The speed in the first part is 2s = 2(8) =
16.
The speed in the first part is 16 mph.
Check:
d = 2s = 2(8) = 16
48 - d = 48 - 16 = 32
The second part is 16 miles. The first part is 32 miles.
16 miles at 8 mph takes 2 hours.
32 miles at 16 mph takes 2 hours.
2 hours + 2 hours = 4 hours.
Our answer is correct.
Answer: The speed in the first part is 16 mph.

Question 9
(a) The distance, Jalaj walks in one day is 4.4 km
(b) The amount Jalaj raises after walking for 22 km at the end of the 5 days is $8
Question 10
(b) The difference between the largest and smallest areas is 2,400 m²
Step-by-step explanation:
Question 9
(a) The distance Jalaj walks in 5 days = 22 km
Whereby Jalaj walks equal distance every day, we have;
The distance, Jalaj walks in one day = 22 km/5 days = 4.4 km/day
The distance, Jalaj walks in one day = 4.4 km
(b) The amount he raises for every kilometer he walks = $1.60
The amount he raises after walking for 22 km at the end of the 5 days = 5 × $1.60 = $8
Question 10
(b) The given side length of the square = 120 meters to the nearest 10 meters
Therefore;
The maximum dimension for the side length of the square = 120 + 10/2 = 125
The largest possible area of the square, [tex]A_l[/tex] = 125 m × 125 m = 15,625 m²
The minimum dimension for the side length of the square = 120 m - 10 m/2 = 115 m
The smallest possible area of the square, [tex]A_s[/tex] = 115 m × 115 m = 13,225 m².
The difference between the largest and smallest areas, [tex]A_l[/tex] - [tex]A_s[/tex] = 15,625 - 13,225 = 2,400 m².

A line is perpendicular to the line given by the equation - 8 = 2y + 3x. What is the slope of the perpendicular line? 3
Answer:
2/3 is the slope of the perpendicular line
Step-by-step explanation:
1) put into slope-intercept form (y=mx+b)
-8=2y+3x
-2y=3x+8
y=-3/2x-4
2) the line is perpendicular so the slope will be opposite and the reciprical of the original slope.
so, because the original was -3/2, the new one is 2/3

Owen made exactly 72% of his free throws during the first half of the basketball season, and he made six free throws during the second half of the season. For the entire season he made exactly 60% of his free throws. What is the fewest possible number of free throws Owen could have attempted during the second half of the season?
Answer:
The fewest possible number of free throws Owen attempted is 15 throws
Step-by-step explanation:
From the first half,
72% = 72/100 = 18/25, reduced to its simplest ratio.
It means that he made at least 18 free throws in the first half of the season.
From the second half,
Let x be the fewest possible outcome of free throws, and the sum of total is 60% = 60/100 = 0.6
Considering the 6 free throws during the second half of the season,
(18+6)/(25+x) = 0.6
24/(25+x) = 0.6
Solving for x,
24 = 0.6(25+x)
24 = 15+0.6x
24-15 = 0.6x
9 = 0.6x
x = 9/0.6 = 15
x = 15 free throws
The fewest possible number of free throws Owen attempted is 15 throws
solve for a
15=3(a+7)
Answer:
