In a week Dave will spend 150 minutes on cardio exercise and 75 minutes on weights. On Monday Dave spent 30 minutes on cardio and 15 minutes on weights. What percentage of his total exercise time for a week did Dave spend exercising on Monday?
A) 20%
B) 25%
C) 10%
D) 50%
Please answer soon
He spent 20% of his exercise time for the week on Monday!
How I got this is by finding the total amount of time spent exercising in the week and the total amount of exercise on Monday. I found that one fifth (1/5) of his exercise time was spent on Monday, or in percentage form, 20%!

Answer:
-12Step-by-step explanation:
Let the equation of the line be x = y - 12
The x intercept occurs at y = 0
Substitute y = 0 into the equation
x = 0 -12
x = -12
Hence the x intercept of the line is -12
Note that the equation was assumed. The same calculation can be employed for any equation given

The width of a rectangle is 2 inches smaller than its length. The perimeter is 24 inches. Find the length and width of the rectangle.
Answer:
7 inches and 5 inches
Step-by-step explanation:
The length the length and width of the rectangle be l and b.
Accodrding to question,
Width, b = l-2
Perimeter, P = 24 inches
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
24 = 2(l+l-2)
12 = 2l-2
14=2l
l = 7 inches
Width, b = 7-2 = 5 inches
Hence, the length and width of the rectangle are 7 inches and 5 inches respectively.

Sam runs a lemonade stand. One day he collected $6.55 in nickels and dimes. The number of nickels was 6 more than half the number of dimes. Find out how many dimes Sam collected.
Answer:
Total number of dimes collected = 50
Step-by-step explanation:
Let the number of dimes collected = d
And the number of nickels collected = n
On day collection in nickels and dimes = $6.55
Since, 1 nickel = $0.05
Therefore, 'n' nickels = 0.05n
And 1 dimes = $0.10
Value of 'd' dimes = $0.10d
Total value of 'n' nickels and 'd' dimes = $(0.05n + 0.10d)
So the equation for the total value will be,
0.05n + 0.10d = 6.55
5n + 10d = 655 --------(1)
Number of nickels was 6 more than half the number of dimes.
n = [tex]\frac{d}{2}[/tex] + 6 ------(2)
By substituting the value 'n' from equation (2) to equation (1)
5([tex]\frac{d}{2}[/tex] + 6) + 10d = 655
[tex]\frac{5d}{2}[/tex] + 30 + 10d = 655
[tex]\frac{25d}{2}[/tex] = 655 - 30
25d = 625 × 2
d = [tex]\frac{1250}{25}[/tex]
d = 50
Therefore, total number of dimes collected = 50

Louis had £3257 in his savings account at the end of the 5 years.
Work out the value of R.
Give your answer correct to 1 decimal place.
Answer:
2.4%
Step-by-step explanation:
The value of R is, 2.4%
What is Simple interest?A quick and easy method of calculating the interest charge on a loan is called a Simple interest.
Given that;
Louis invested £2950 in a savings account for 5 years.
He was paid 1.9% per annum compound interest for each of the first 4 years.
And, He was then paid R% interest for the fifth year.
Louis had £3257 in his savings account at the end of the 5 years.
Here, We know that;
⇒ Compound interest formula = Capital × (1 + r%) ⁿ
Where, n is time in years.
So, We can formulate;
⇒ £2950 × (1 + 0.019)⁴
⇒ £3180.67
And, For calculate R;
⇒ £3180.67 × (1 + R%)⁵ = £3257
⇒ R = 2.4%

The expressions given represent the measures of the acute angles of a right triangle Find the measure of each acute angle.
Answer:
30, 60
Step-by-step explanation:
The sum of a triangles angles should be 180.
Subtract 90 because it's a right triangle.
180 - 90 = 90
Now we know the sum of the other angles should be 90.
x + 2x = 90
Solve for x.
3x = 90
x = 30
Now you substitute 30 for x.

Answer:
12x +12y = 7
Step-by-step explanation:
The 2-point form of the equation for a line is useful.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (1/3 -1/4)/(1/4 -1/3)(x -1/3) +1/4
y = (1/12)/(-1/12)(x -1/3) +1/4)
y = -x +1/3 +1/4
Add x and multiply by 12.
x +y = 1/3 +1/4
12x +12y = 4 +3
12x +12y = 7
A tree measured 12 1/2
feet tall. Over the next 5 1/2
years it grew to be 51 feet tall.
During the 5 1/2
years, what was the average yearly growth rate of the tree?
Answer:4.08 ft a year or 1 and 5/8 feet a year (approx)
Step-by-step explanation:
It's 12.5 feet the first year
51 feet 5 years later
If you do the math and divide 51 by 12.5, you get 4.08 which is around 1 and 5/8 ft
12.5x4.08 is 51 feet.
So the tree grows approximately 1 and 5/8 feet a year

what is the value of y?
For the given triangle the measure of the angle y is 65°.
Hence the correct option is C.
The angles that are created outside of a triangle are its external angles.
In other terms, the angle created between one of a triangle's sides and its neighboring extended side is the triangle's exterior angle.
And the exterior angle of a triangle is the sum of the interior angles of opposite sides.
The given angles are:
Exterior angle = 130°
Interior angles are y° and y°
Therefore,
Exterior angle = y° + y°
130° = y° + y°
2y° = 130
Dividing both sides by 2 we get,
y° = 65°
Hence,
The measure of the angle y is 65°.

A spherical balloon is inflating with helium at a rate of 64π ft/min. How fast is the balloon's radius increasing at the instant the radius is 2 ft? How fast is the surface area increasing?
The balloon's radius is increasing at a rate of...
Answer:
let r ,v be the radius and volume of sphere.
dv/dt=64πft³/min
r=2ft
Dr/dt=?
Step-by-step explanation:
we have
volume of sphere=4/3πr²
v=4/3πr²
differentiating both side with respect to t we get
dv/dt=4πdr²/dr×dr/dt=4π×2r×dr/dt=8/3×πr×dr/dt
substituting the given value we get
dv/dt=8/3×πr×dr/DT
64π×3/(8π×2)=dr/dt
Dr/dt=12ft/min
The balloon's radius is increasing at a rate of12 ft/min
The balloon's radius increasing at the instant the radius is 2 ft will be 10106.47 ft³ per minute.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
A spherical balloon is inflating with helium at a rate of 64π ft/min.
dr/dt = 64π ft/min
Then the balloon's radius increasing at the instant the radius is 2 ft will be
V = (4/3)πr³
Differentiate with respect to time. Then we have
[tex]\rm V' = \dfrac{dV}{dt} \\\\ V' = \dfrac{4}{3}\cdot \pi 3r^2 \cdot \dfrac{dr}{dt}[/tex]
Simplify the equation, then we have
V' = 4πr² × 64π
V' = 4π × (2)² × 64π
V' = 10106.47 ft³ per minute
The balloon's radius increasing at the instant the radius is 2 ft will be 10106.47 ft³ per minute.
