Answer:
He can build 3 toys in 4 minutes.
Step-by-step explanation:
Divide 360 by 8 since you are dividing it first to get the number of toys he can build in an hour. As a result, he can build 45 toys in an hour. Divide that number by 15 since 4 times that number equals an hour. You should get 3 toys as your final result.
For easier explanation, multiply 8 and 15 together to get 120 for better understanding. Divide that number from 360 to get the same answer.

6x + 3y = 12
4x + y = 14 what is the solution
Answer:
x=5 y=-6
Step-by-step explanation:
6x + 3y = 12 , 4x + y = 14
4x*3+y*3=14*3
12x+3y=42 , 6x+3y=12
(12x-6x)+(3y-3y)=30
6x=30, x=5
4*5 + y = 14
y=-6
A food store makes a 11-lb mixture of oatmeal, crispies, and chocolate chips. The cost of oatmeal is $1.50 per pound, crispies cost $2.00 per pound, and chocolate chips cost $1.00 per pound. The mixture calls for twice as much oatmeal as crispies. The total cost of the mixture is $17.00. How much of each ingredient did the store use?
Answer:
6 pounds of oatmeal, 3 pounds of crispies and 2 pounds of chocolate chips were used.
Step-by-step explanation:
Let,
x be the pounds of oatmeal used
y be the pounds of crispies used
z be the pounds of chocolate
According to given statement;
1.50x+2.00y+1.00z = 17.00 Eqn 1
x+y+z = 11 Eqn 2
x = 2y Eqn 3
Putting x=2y in Eqn 2
2y+y+z = 11
3y+z = 11 Eqn 4
From Eqn 4
z = 11 - 3y Eqn 5
Putting value of x and z from Eqn 3 and Eqn 5 in Eqn 1
1.50(2y) + 2.00y + 1(11-3y) = 17.00
3y+2y+11-3y=17
[tex]2y=17-11\\2y=6\\\frac{2y}{2}=\frac{6}{2}\\y=3[/tex]
Putting y = 3 in Eqn 3
x= 2(3)
x= 6
Putting in Eqn 2
6 + 3 + z = 11
z = 11-9
z= 2
Hence,
6 pounds of oatmeal, 3 pounds of crispies and 2 pounds of chocolate chips were used.

A rectangular book measures 4 x 7. What is the length of its
diagonal?
A rectangular book measures 4 x 7, the length of its diagonal is √65.
Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In mathematical terms, if a and b represent the lengths of the two shorter sides (also known as legs) of a right triangle, and c represents the length of the hypotenuse, then the Pythagorean theorem can be expressed as:
a² + b² = c²
Given:
Base = 4
Length = 7.
To determine the length of diagonal by using Pythagorean theorem.
Diagonal² = Base² + Length²
Plugging the values in Pythagorean theorem.
Diagonal² = 4² + 7²
Diagonal = √(16 + 49) =√65.
Therefore, the length of diagonal of book is √65.

Shannon and Bob are members of a cross-country team. Bob runs at a rate of 8 kilometers per hour and Shannon runs at a rate of 10 kilometers per hour. If the distance around the team's practice course is 1.7 kilometers, how much longer does it take Bob to complete one trip around the course than Shannon, to the nearest tenth of a minute?
Answer:
2.6 minutes
Step-by-step explanation:
Speed of Bob = 8 km/hr
Speed of Shannon = 10 km/hr
Distance of practice course = 1.7 km
As time = (distance)/(speed), so
Time taken by Bob to cover the distance, t1 = 1.7/8=0.2125 hours
Time taken by Shannon to cover the distance, t2 = 1.7/10= 0.17 hours
As t1 > t2, so, Bob takes more time than Shannon to complete the course.
t1-t2= 0.2125-0.17 = 0.0425 hours = 0.0425 x 60 minutes= 2.55 minutes.
On rounding up to tenth digit, t1-t2 = 2.6 minutes.
Hence, It takes 2.6 minutes more time for Bob to complete one trip around the course than Shannon
A cleaning company charges $3 per square foot and a flat fee of $100. Which of the equations below shows the cost y, in dollars, of cleaning a patio that is x square foot? Hint: find the key words and corresponding amounts for "m" and "b."
Step-by-step explanation:
Y= 3x + b
As, to know the total, which is y, we need to solve for the cost
So first for money per square foot = $3
For square foot = x
So, price for x square foot = $3x (here this is the value of m)
Now, for value b,
$100 is added to the cost as its the charge, as the flat fee
So the value of b = $100
So, y=3x+100

Harold opened a credit card at a department store with an APR of 14.55% compounded monthly. What is the APY on this credit card?
Answer:
the APY on this credit card is 15.56%
Step-by-step explanation:
The computation of the APY is as followS:
The nominal monthly rate is
= 0.1455 ÷ 12
= 0.012125
Now
real annual rate= [(1 + Nominal monthly rate)^number of months] - 1
= [(1.0.12125^12) - 1]
= 15.56%
Hence, the APY on this credit card is 15.56%

A shoe store uses a 38% markup to price their items. The store buys the
shoes from the wholesaler for $52. By how much will they mark up the price?
Answer:
They will Markup the price by $19.76.
Step-by-step explanation:
Markup percent = 38%
Wholesale Price = $52
Markup price can be calculated by simply multiplying the wholesale price by 38% or 0.38.
so
Markup price = 38% of 52
= 38/100 × 52
= 0.38 × 52
= $19.76
Therefore, they will Markup the price by $19.76.
What is the equation of the line perpendicular to the line y = 2x + 3 with a y-intercept of -6
Answer:
y = -¹/₂ x - 6Step-by-step explanation:
Two lines are perpendicular if the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = 2x + 3 ⇒ m₁=2
2×m₂ = -1 ⇒ m₂ = -¹/₂
The y-intercept is b=-6 so the equation in slope-intercept form:
y = -¹/₂ x - 6

Harry and Tim both made New Years resolutions. Harry made 5 more resolutions than Tim. Together they made 13 resolutions. How many resolutions did Harry make?
Answer:
Harry made 9 resolutions
Step-by-step explanation:
Okay, so the first thing that we have to do is divide 13 by 2.
Of course, it wouldn't equal so let's just say 6.
So both boys made around 6 resolutions each.
Now we have to take into consideration the 5 more resolutions that Harry made.
What I did to answer this question was I kept taking away Tim's resolutions and giving them to Harry until Harry had 5 more resolutions than Tim.
Finally, my resolution ratio came to 4:9
Tim made 4 resolutions and Harry made 9
In conclusion, Harry made 9 resolutions.
Plz mark me brainliest :)
There are 9 resolutions did Harry make.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Harry and Tim both made New Years resolutions.
Harry made 5 more resolutions than Tim.
And, Together they made 13 resolutions.
Now,
Let number of resolution Tim make = x
Then, Number of resolution Harry make = x + 5
Since, Together they made 13 resolutions.
Hence, We get;
⇒ x + (x + 5) = 13
⇒ 2x = 13 - 5
⇒ 2x = 8
⇒ x = 4
Thus, Number of resolution Harry make = x + 5
= 4 + 5
= 9

A shop sells a party hat at x dollars and a mask at y dollars. On a particular morning, 10 hats and 20 masks were sold for $30. In the afternoon, 8 hats and 10 masks were sold for $18. What is the cost of one hat and one mask? Let Hat be "H" and Mask be "M"
Answer:

Step-by-step explanation:
i think... seems the only reasonable answer
The cost of one hat is $1 and cost of one mask is $1.
What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have 10 hats and 20 masks were sold for $30.
and, 8 hats and 10 masks were sold for $18.
let the cost of one hat be H and cost one Mask be M.
So, the system of Equation we get
10H + 20M = 30..........(1)
8H + 10M = 18...........(2)
Solving the above equation we get
10H - 16H = 30 - 36
-6H = -6
H = 1
and, 10 + 20M= 30
20M= 20
M= 1
