Answer:
0.395 kilometre
Step-by-step explanation:
Given:
On Martin's first stroke, his golf ball traveled 4/5 of the distance to the hole.
On his second stroke, the ball traveled 79 meters and went into the hole.
Question asked:
How many kilometres from the hole was Martin when he started?
Solution:
Let distance from Martin starting point to the hole in meters = [tex]x[/tex]
On Martin's first stroke, ball traveled = [tex]\frac{4}{5} \ of \ total \ distance\ to\ the\ hole[/tex]
[tex]=\frac{4}{5} \times x=\frac{4x}{5}[/tex]
On his second stroke, the ball traveled and went to the hole = 79 meters
Total distance from starting point to the hole = Ball traveled from first stroke + Ball traveled from second stroke
[tex]x=\frac{4x}{5} +79\\ \\ Subtracting\ both\ sides\ by \ \frac{4x}{5}\\ \\ x- \frac{4x}{5}= \frac{4x}{5}- \frac{4x}{5}+79\\ \\ \frac{5x-4x}{5} =79\\ \\ By \ cross\ multiplication\\ \\ x=79\times5\\ \\ x=395\ meters[/tex]
Now, convert it into kilometre:
1000 meter = 1 km
1 meter = [tex]\frac{1}{1000}[/tex]
395 meters = [tex]\frac{1}{1000}\times395=0.395\ kilometre[/tex]
Thus, there are 0.395 kilometre distance from Martin starting point to the hole.

A cone-shaped kitchen funnel has a diameter of 6 inches and a height of 7 inches. About how many times would you need to fill the funnel to fill a cylindrical can that has a radius of 4 inches and a height of 13 inches?
A. 3
B. 4
C. 9
D. 10
Answer:
The funnel will fill the container in about 10 times
Step-by-step explanation:
To solve this question, the principal thing to do is to calculate the volumes of the cone-shaped funnel and the cylinder to actually know the number of times we will need to fill the funnel so as to fill the cylinder,
These number of times can simply be calculated by dividing the volume of the cylinder by the volume of the cone-shaped funnel.
Mathematically, we proceed as follows;
Volume of the cone funnel = 1/3 ×π× [tex]r^{2}[/tex]× h, where r and h represents the radius and height of the cone respectively.
From the question D = 6 inches, and mathematically r = D/2 = 6/2 = 3 inches and h = 7 inches
Plugging the values we have in the question, the volume = 1/3 ×π×[tex]3^{2}[/tex]×7 = 21π [tex]inches^{3}[/tex]
For the cylindrical receptacle, we have the volume calculated as π× [tex]r^{2}[/tex]× h
Where r = 4 inches and h = 13 inches.
Plugging these values we have ; π × [tex]4^{2}[/tex]× 13 = 208π [tex]inches^{3}[/tex]
Now the number of times is simply = volume of cylindrical container/volume of cone-shaped funnel
= 208π/21π = 208/21 = 9.9 which is approximately 10 times

Step-by-step explanation:
2x - 3y = -6
Convert this equation to Slope-Intercept form.
2x - 3y - 2x = -6 - 2x
-3y = -6 - 2x
Divide both sides by -3
y = (-6 - 2x)/ (-3)
y = 2 + 2x/3
slope is (2/3) and y-intercept is 2

Margaret is planning a wedding reception. She wants to spend less than her budget of 5,676, and margaret has already spent 2,652. The meal price per guest is 28. How many guests, x, can margaret invite to the reception and stay under budget?
Final answer:
To determine how many guests Margaret can invite to stay under budget, follow the steps to calculate the maximum number of guests based on the remaining budget and meal price per guest.
Explanation:
To determine how many guests Margaret can invite to stay under budget, follow these steps:
Calculate how much budget Margaret has left: $5,676 - $2,652 = $3,024.Divide the remaining budget by the meal price per guest to find out the maximum number of guests she can invite: $3,024 ÷ $28 = 108. Therefore, Margaret can invite a maximum of 108 guests and stay under budget.Which expression matches: 7 less than the product of 4 and 5

The product of 4 and 5 means that 4 and 5 are multiplied together.
"7 less than," means subtracting 7.
That means you get 4(5) - 7
A train leaves at 17.22 and arrives at its destination at 18.14.
If the train travelled 56 km, what was it's the average speed in km/h?
Give your answer rounded to 1 dp.
The train's average speed was calculated by using the formula for average speed (Total distance \/ Total time), resulting in approximately 64.4 km/h, after converting the total journey time from minutes to hours.
To calculate the average speed of the train, we can use the formula:
Average speed = Total distance \/ Total time
First, we find the total time taken by the train for its journey:
Departure time: 17:22
Arrival time: 18:14
Total time = Arrival time - Departure time
Total time = 18:14 - 17:22
Total time = 52 minutes
To convert minutes to hours (since speed is in km/h), we divide by 60:
Total time in hours = 52 / 60 ≈ 0.87 hours
Now, we can plug in the given distance and calculated time into the formula:
Average speed = 56 km / 0.87 hours ≈ 64.4 km/h
Hence, the train's average speed was approximately 64.4 km/h, rounded to 1 decimal place.

change the equation 8x-7y+8=0 into an equivalent equation written in the slope-intercept form
Answer:
Slope = 2.286/2.000 = 1.143
Step-by-step explanation:
To convert 8x - 7y + 8 = 0 to slope-intercept form, first, isolate y by moving terms, then divide by the coefficient of y to find the slope and intercept values as per the equation y = mx + b.
To change the equation 8x - 7y + 8 = 0 to slope-intercept form (y = mx + b), you need to solve for y. Here's the step-by-step process:
Move the term 8x to the right side by subtracting 8x from both sides, giving -7y = -8x - 8.
Divide by -7 to isolate y, resulting in y = (8/7)x + 8/7.
Therefore, the equivalent equation in slope-intercept form is y = (8/7)x + 8/7.

Answer: 5F < 5( X + x )
Step-by-step explanation:
Let each finger = F and
The index finger = X
The shortest index finger = x
the combined length of all 5 of her fingers on one hand should be less than 5 times the length of index finger
From the statement above, we get
5F < 5X

If the required value of y is -108.5, use the fit line equation y = -2.61x + 152.51 to determine the needed x-value. Round to the nearest whole number. *
Final answer:
To determine the needed x-value when the required value of y is -108.5, substitute the value of y into the fit line equation and solve for x. The rounded x-value is 100.
Explanation:
To determine the needed x-value when the required value of y is -108.5 using the fit line equation y = -2.61x + 152.51, we can substitute the value of y into the equation and solve for x.
-108.5 = -2.61x + 152.51
Subtract 152.51 from both sides: -108.5 - 152.51 = -2.61x
Simplify: -261.01 = -2.61x
Divide both sides by -2.61: x = -261.01 / -2.61
Rounding to the nearest whole number, x = 100.

A restaurant is offering a special deal on pizza and drinks. You can get 2 large pizzas and 4 large drinks for $16. Or, you can get 4 large pizzas and 7 large drinks for $30. How much would each pizza (p) and each drink (d) cost separately?
Answer:
p=4 d=2
Step-by-step explanation:
To do this, we can set up a system of equations.
Special Deal 1:
2p+4d=16
Special Deal 2:
4p+7d=30
Now we can set this up for elimination, and try to eliminate the p variable.
Let's do this by multiplying the entire equation for Special Deal 1 by 2.
2(2p+4d=16)
4p+8d=32
Now we can eliminate p by subtracting the equation for special deal 2, by the equation for special deal 1.
4p+8d=32 minus
4p+7d=30 equals
d=2
Now we can plug that into the original equation to find the cost of p.
2p+4(2)=16
2p+8=16
Subtract 8 from both sides.
2p=8
p=4
Therefore, a pizza costs $4 and a drink costs $2.
Answer: p=4 d=2

Would i solve this doing 14+5 or 14-5 to get the missing length?
Answer:
The answer to your question is 10 ft
Step-by-step explanation:
We can observe that all the sides have a length but the first to the left.
Also, we know the corners meet at right triangles, so to calculate the length of the missing side, we must add to sides.
But these sides must be the ones that are in front of it (6 ft and 4 ft)
Then ? = 6 + 4
10 ft
