A car is traveling at a steady speed. It travels 2 1/2 miles on 3 1/3 minutes. How will it travel in 43 minutes? 1 hour?
Answer:
32.25 miles in 43mins
45miles in an hour
Step-by-step explanation:
Divide '2 1/2' by '3 1/3' to find the distance done in a minute: 0.75 miles
Multiply the distance done in a minute(0.75) by 43 to find the distance done in 43 minutes: 32.25miles
Multiply the distance done in a minute(0.75) by 60 to find the distance done in an hour: 45miles
152=8(3a-2) justify each step
Step-by-step explanation:
152 = 8(3a - 2)
152 = 8 × 3a - 8 × 2
152 = 24a - 16
152 + 16 = 24a
168 = 24a
a = 168/24
a = 7
Answer:
-7
Step-by-step explanation:
152=8(3a-2)
8(3a-2)=152
8(3a-2)/8=(152){8)
3a-2=19
3a-2+2=19+2
3a=21

Answer:
4x + -6.03 = 2.07
Step-by-step explanation:
first one:
there are four big white boxes so that equals 4x
6 negative ones so its -6
3 negative 0.1 so its -0.3
add up 06 and -0.3 and that's -6.03
second one:
there are two squares that each equal one so that would be two and add the 7 0.1's and that will be 2.07
Pleas help me with this F(x)=3x-x Find F(10)
Answer:
f(10) = 20
Step-by-step explanation:
Since the x is defined, you can plug it in, x=10.
Substitute the x with 10, f(10) = 3(10)-10.
Then, simply the equation, f(10) = 20.
Which number line represents the solutions to \X – 5| = 1?
Answer:
Second number line represents the [X-5]=1.
Step-by-step explanation:
Given : [X-5]=1 .
To find : Which number line represents the solutions to [X-5]=1.
Solution : We have given that [X-5]=1.
We can se the value x-5 is inside the modulus it may be positive or negative.
So, we will do it by both cases.
1) (x - 5) = 1
On adding by 5 both sides.
x = 1+5 = 6
x = 6.
2) if -(x-5) = 1
remove parenthesis
-x +5 = 1
On subtracting by 5 both side
-x = -4
On dividing by -1 both side
x = 4.
So , x = 4, 6.
Therefore , the second number line represents the [X-5]=1.

The Nguyen family is traveling cross-country, driving 300 miles each day. Let 2 represent the number of days in the trip and let y represent the total number
of miles driven.
Write an equation to model their trip.
Enter the correct equation in the box.
Step-by-step explanation:
y = Total number of miles driven
= Number of days * Number of miles per day
= (x) * (300).
Therefore the equation is y = 300x.
When x = 2, y = 300(2) = 600.
The Nguyen family drove 600 miles during the 2 days.
Convert:4 gal= qt what is it
Answer:
4 gallon = 16 quarts
Step-by-step explanation:
Consider the provided information.
We need to convert gal into qt
We know that 1 gallon = 4 quarts
Now in the given question, we have 4 gal.
Multiply both the sides by 4
1×4 gallon = 4×4 quarts
4 gallon = 16 quarts
Hence, 4 gallon is equal to 16 quarts.

XY zand ABC are similar. If angle X is 32 degrees and angle Y is 84
degrees, find the measure of angle C.
Answer:
B
Step-by-step explanation:
A triangle always has a degree total of 180. x+y=116 180-116=64 therefore the last angle, angle c, must be 64 degrees.
Answer: B. 64 degrees
Step-by-step explanation:
∠C = 180° - (∠X + ∠Y)
∠C = 180° - (32° + 84°) = 180° - 116° = 64°

-1/6 x -3/5 the answer has to be a fraction
The product of -1/6 x -3/5 = 1/10
The given expression is,
-1/6 x -3/5
In mathematics, a fraction is defined as a portion of the total. If a pizza is cut into four equal pieces, each slice is represented by 14. Fractions make it easier to distribute and assess numbers and speed up calculations. The depiction of fractions appears easier without the use of decimal values.
Now proceed the product,
Multiply numerator with numerator and denominator with denominator,
Therefore,
-1/6 x -3/5 = -1x(-3)/6x5
= 3/30
= 1/10
Hence,
-1/6 x -3/5 = 1/10

Given that AB = 370 m and AC = 510 m, find
(i) the distance between B and C,
(ii) ACB,
(iii) the bearing of C from B,
(iv) the shortest distance from A to BC.
Answer:
(i) The distance between B and C is approximately 552.9 m
(ii) ∠ACB is approximately 40.49°
(iii) The bearing of C from B is approximately 184.49°
(iv) The shortest distance from A to BC is approximately 331.155 m
Step-by-step explanation:
The given parameters are;
The length of segment AB = 370 m
The length of segment AC = 510 m
The bearing of B from A = 68°
The bearing of C from A = 144°
(i) From the bearing of B from A = 68° and the bearing of C from A = 144°, we have;
∠BAC = 144° - 68° = 76°
∠BAC = 76°
Let A represent ∠BAC, c represent segment AB, b represent segment AC, and a represent segment BC, by cosine rule, we have;
a² = b² + c² - 2·b·c·cos(A)
By substituting the known values, we get;
a² = 510² + 370² - 2 × 510 × 370 × cos(76°)
a² ≈ 397000 - 91301.3234 ≈ 305698.677
BC = a ≈ √(305,698.677) ≈ 552.9
The distance between B and C, BC ≈ 552.9 m
(ii) By sine rule, we have;
a/(sin(A) = b/(sin(B)) - c/(sin(C))
Therefore;
552.9/(sin (76°)) = 370/(sin(C))
sin(C) = 370/(552.9/(sin (76°))) ≈ 0.649321
C = arcsine(0.649321) ≈ 40.49°
∠C = ∠ACB ≈ 40.49°
(iii) Angle ∠B = ∠ABC = 180° - 76° - 40.49° ≈ 63.51°
The bearing of A from B = 360° - (180° - 68°) = 248°
Therefore, the bearing of C from B ≈ 248° - 63.51° ≈ 184.49°
(iv) The shortest distance from A to BC = 370 m × sin(63.51°) ≈ 331.155 m

Brian spends the same amount of money each morning. On Saturday he bought a large coffee for $1.25 and 2 doughnuts. On Sunday he brought a small coffee for $.50 and 5 doughnuts. Write and solve an equation to determine the cost of one doughnut.
Answer:
Cost of one doughnut is $0.25
Step-by-step explanation:
Let the rate of one doughnut = $x
On Saturday he bought a large coffee and 2 doughnuts.
Cost of one large coffee = $1.25
Cost of 2 doughnuts = $2x
Total cost = $(1.25 + 2x)
On Sunday, he bought a small coffee and 5 doughnuts.
Cost of one small coffee = $0.50
Cost of 5 doughnuts = $5x
Total cost = $(0.50 + 5x)
Since, Brian spent same amount of money each morning,
Total expenditure on Saturday morning = Total expenditure on Sunday morning
(1.25 + 2x) = (0.50 + 5x)
1.25 - 0.50 = 5x - 2x
0.75 = 3x
x = $0.25
Therefore, cost of one doughnut is $0.25
