Answer:
The distance of the park from the Gary's house is 125 miles.
Step-by-step explanation:
Speed of Gary = 50 miles/hour
Time taken by Gary to reach the park from his house = 2.5 hours
Now, we know that,
Distance travelled = speed × time
So, distance between park and Gary's house = speed × time
= 50 × 2.5
= 125 miles
So, the park is 125 miles away from the Gary's house.

Answer: X = 2
Step-by-step explanation: In this problem, notice that x is being divided by 2. So to get x by itself, we need to multiply both sides of the equation by 2.
Notice that on the left side, the 2 and 2 cancel each other out so we are just left with x. On the right side, we have 1 x 2 which is 2 so x = 2.
Finally, we can check our answer by plugging a 2 back into the original equation. So we have [tex]\frac{(2)}{2} = 1[/tex] which is a true statement so we know that our answer is correct.
rick school is 30 miles from the hostipital. the school and hospital are 3/5inch apart on an online map.the hostipal is 4 inches from the airport on the map. hom far from the hostpital is the airport?
Answer: 200 miles
Step-by-step explanation: 1/5 is equal to 10miles so you 5/5 is 50 miles or 1 inch on the map.
Final answer:
The distance from the hospital to the airport on the map is 18 inches.
Explanation:
To find the distance from the hospital to the airport, we can use the scale of the map. Since the school and hospital are 3/5 inch apart on the map, and the school is 30 miles away from the hospital, we can set up the proportion:
3/5 inch = 30 miles
x inch = distance from hospital to airport
Cross-multiplying, we get 5x = 3 * 30
x = 18
Therefore, the distance from the hospital to the airport is 18 inches on the map.
by what would you multiply each side of the equation ax=27 to solve x
Answer:
Step-by-step explanation:
ax= 27........I would normally solve this by division....but it says multiply....so multiply both sides by 1/a
example :
3x = 27.....multiply both sides by 1/3
1/3(3/1)x = 27 * 1/3
x = 27/3 which reduces to 9

Your teacher is giving you a test worth 100 points containing 40 questions. There are two point and to
ur point questions on the test. How many of each type of question are on the test?
Answer:
There are 30 two point questions and 10 four point questions on the test.
Step-by-step explanation:
Given:
Your teacher is giving you a test worth 100 points containing 40 questions. There are two point and four point questions on the test.
Now, to find number of each type of question are on the test.
Let the two point questions be [tex]x[/tex].
And let the four point questions be [tex]y[/tex].
So, total questions:
[tex]x+y=40.[/tex].........( 1 )
⇒ [tex]y=40-x.[/tex]
Now, total number of points of the questions on the test:
[tex]2x+4y=100.[/tex]
Substituting the value of [tex]y[/tex]:
⇒ [tex]2x+4(40-x)=100[/tex]
⇒ [tex]2x+160-4x=100[/tex]
⇒ [tex]160-2x=100[/tex]
Adding both sides by [tex]2x[/tex] we get:
⇒ [tex]160=100+2x[/tex]
Subtracting both sides by 100 we get:
⇒ [tex]60=2x[/tex]
Dividing both sides by 2 we get:
⇒ [tex]30=x[/tex]
⇒ [tex]x=30[/tex].
The number of two point questions = 30.
Putting the value of [tex]x[/tex] in the equation ( 1 ) we get:
[tex]30+y=40.[/tex]
Subtracting both sides by 30 we get:
⇒ [tex]y=10.[/tex]
The number of four point questions = 10.
Therefore, there are 30 two point questions and 10 four point questions on the test.

A 2-liter bottle of soda (67.6 ounces) costs $1.89. A case of twelve 12 ounce
cans of the same soda costs $2.99. Calculate the unit price (price/ounce) of each
item and determine which is the better bargain. Explain your answer.
Answer:
The two-liter bottle of soda has a unit price of $0.028/ounce.
The case of twelve 12 ounces has a unit price of $0.021/ounce.
The case of twelve 12 ounce can is the better bargain.
Step-by-step explanation:
A two-liter bottle of soda i.e. 67.6 ounces cost $1.89.
So, the unit price (price/ounces) of this type of soda is [tex]\frac{1.89}{67.6} = 0.028[/tex] dollars per ounce.
Again, a case of twelve 12 ounce cans of the same soda costs $2.99.
So, the unit price (price/ounces) of this type of soda is [tex]\frac{2.99}{12 \times 12} = 0.021[/tex] dollars per ounce.
Therefore, the case of twelve 12 ounce can is the better bargain. (Answer)

A bulletin board has a perimeter of 200 inches. Which equation expresses the area A(w) of the bulletin board as a function of its width, w?
A. A(w) = 100w - w2
B. A(w) = 200w - w2
C. A(w) = w2 – 100w
D. A(w)=w2 - 200w
The equation that expresses the area A(w) of the bulletin board as a function of its width w is A(w) = w².
Explanation:To express the area A(w) of the bulletin board as a function of its width, we need to find the equation that relates the width to the area. Since the perimeter of the bulletin board is given as 200 inches, we can use the formula for the perimeter of a rectangle: P = 2w + 2l, where w is the width and l is the length. Since the bulletin board is assumed to be a rectangle, the length is equal to the width. We can rewrite the formula as 2w + 2w = 200, which simplifies to 4w = 200. Solving for w, we find w = 50.
Now that we know the width, we can express the area A(w) as a function of w. Since the area of a rectangle is given by the formula A = length * width, and the length is equal to the width in this case, we have A(w) = w * w = w².
The correct equation that expresses the area A(w) of the bulletin board as a function of its width w is A(w) = w², which corresponds to option D.

he expression $130-60t$130−60t represents the distance, in miles, the counselor still needs to drive after $t$t hours.
What does the $60$60 in the expression represent?
Answer:
Speed of the counselor is represented by 60 and is equal to 60 mph
Step-by-step explanation:
Given:
The expression that represents the distance, in miles, the counselor still needs to drive after 't' hours is given as:
[tex]d=130-60t\\d=-60t+130[/tex]
The above expression is of the form of a standard linear equation:
[tex]y=mx+b[/tex]
Here, 'm' represents the slope or rate of change of 'y' with 'x' and 'b' is the y-intercept or initial value of 'y' when 'x' was 0.
On comparing the standard equation with the given equation, we conclude that:
[tex]m=-60[/tex]
Therefore, the slope here represents the change in distance with time 't'.
We know that, change in distance with time is nothing but the speed.
So, the speed of the counselor is 60 mph.
Therefore, the term 60 represents the speed of the counselor.
(4x+7) and [5(x-4)} what is the value of x
Answer:
The value of x is 27
Complete question and statement:
(4x + 7) = [5(x - 4)} what is the value of x?
Source: Previous question that can be found at brainly
Step-by-step explanation:
Let's solve for x, (4x + 7) = [5(x - 4)]
(4x + 7) = [5x - 20]
4x + 7 = 5x - 20
4x - 5x = - 20 - 7 (Subtracting - 5x and - 7 at both sides)
- x = - 27
x = 27 (Multiplying by -1 at both sides)
The value of x is 27
length of a room is 3 times its breadth and height is 4.6 m.if the total cost of carpeting the floor of a room at the rate of Rs. 60 per square meter is Rs. 4500,Find the total cost of papering the 4 walls at the rate of Rs. 6.
The student's homework question involves the calculation of a room's floor area for carpeting costs and then determining the wall area for papering costs, utilizing given ratios and costs per square meter.
The question involves calculating the area of a room's floor and using that to determine the cost of carpeting, followed by calculating the cost of papering the walls. To solve for this, we use the given ratio of the length being 3 times the breadth (let's say the breadth is 'b', then the length would be '3b'). When the carpeting cost of Rs. 60 per square meter totals Rs. 4500, we can find the area of the floor by dividing the total cost by the per square meter cost, which gives us an area of 75 square meters (i.e., 4500 / 60 = 75 m2).
Assuming the room to be a rectangle, the length and breadth can be determined from the area (since length times breadth = area), and given the relationship between length and breadth, we can solve for 'b' and then find '3b'. Once we have the dimensions of the floor, we can calculate the perimeter (2 times (length + breadth)) and use the given height to find the total area of the walls. The cost of papering is then determined by multiplying the wall area by the cost per square meter (Rs. 6 in this case).

The expression to represent the cost, in dollars, for 5 people to go horseback riding for 2 hours each is $ (15 + 10x)
Solution:
Given that The total cost to go horseback riding is "x" dollars per hour plus a $3 fee for renting a helmet.
total cost = $ 3 + "x" dollars per hour
To find: expression to represent the cost, in dollars, for 5 people to go horseback riding for 2 hours each.
Let us first find the total cost for 1 person to horse ride for 2 hours
total cost for 1 person = $ 3 + 2x
Thus to find total cost for 5 people to go horseback riding for 2 hours each is found by multiplying the above expression by 5
Total cost for 5 people = 5 x total cost for 1 person
[tex]\text{ Total cost for 5 people } = 5 \times (3 + 2x)[/tex]
[tex]\text{ Total cost for 5 people } = 15 + 10x[/tex]
Thus the expression to represent the cost, in dollars, for 5 people to go horseback riding for 2 hours each is $ (15 + 10x)

What is the lcm of 1 and 5
Answer:
5
Step-by-step explanation:
The LCM of 1 and 5 is 5, as 1 is a factor of all numbers and thus does not change the other number when finding the LCM.
The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both of the given numbers. In the case of 1 and 5, the LCM can be found by simply taking the larger number since 1 is a factor of all integers which therefore, gives the LCM of 1 and 5 as 5. There isn't really a need for a complex calculation because any number multiplied by 1 remains unchanged.

Find the primary solution of cosθ=−0.3
The primary solution for [tex]\( \cos \theta = -0.3 \) is approximately \( \theta \approx 109.47^\circ \) within \( [0^\circ, 360^\circ) \).[/tex]
To find the primary solution of [tex]\( \cos \theta = -0.3 \), we need to determine the angle \( \theta \) within the interval \( [0^\circ, 360^\circ) \) that satisfies this equation.[/tex]
1. **Using Inverse Cosine Function**: Since[tex]\( \cos \theta = -0.3 \), we need to find the angle whose cosine is -0.3. We use the inverse cosine function \( \arccos \) to find \( \theta \):[/tex]
[tex]\[ \theta = \arccos(-0.3) \][/tex]
2. **Evaluate the Inverse Cosine**: We evaluate [tex]\( \arccos(-0.3) \)[/tex] using a calculator or a trigonometric table. This gives us the angle in radians.
3. **Convert Radians to Degrees (if necessary)**: If the solution is given in radians, we convert it to degrees since the interval given is in degrees. Recall that [tex]\( 180^\circ = \pi \) radians. To convert radians to degrees, multiply by \( \frac{180}{\pi} \).[/tex]
4. **Check Interval**: Finally, we ensure that the angle [tex]\( \theta \)[/tex] is within the interval [tex]\( [0^\circ, 360^\circ) \). If the angle is greater than or equal to \( 360^\circ \), we subtract multiples of \( 360^\circ \)[/tex]until we get an angle within the desired interval.
5. **Final Result**: The angle [tex]\( \theta \)[/tex] found in step 4 is the primary solution of the given equation.
In summary, the detailed stepwise solution involves using the inverse cosine function to find the angle whose cosine is -0.3, evaluating this angle, converting it to degrees if necessary, and ensuring it falls within the desired interval.
