Mickey used these calculations to find how much he would spend on 7 cartons of eggs, if 12 cartons of eggs cost $22.20. Describe his error.
12 cartons(÷22.20)
$22.22(÷22.20)
Unit price = $0.54
$0.54(7) = $3.78
Answer ; Mickey set up the equivalent rate wrong. The cartons of eggs should be in the denominator, because you need to find the unit price for 1 carton of eggs.
Answers
Answer: you would divide the total price of $22.20 by the amount of cartons, which is 12, giving you the unit rate of $1.85 per carton. the unit rate, $1.85 multiplied by 7 is $12.95, so it would cost $12.95 for 7 cartons of eggs

Question 8

Answers
Answer:
6.6
Step-by-step explanation:
The way to do this is to find the tax as a decimal. Worry about the 100 later.
54 * x = 3.56
Divide by 54
x = 3.56/54
x = .06593
Now use the 100
0.06592 * 100 = 6.593
But you want it rounded to the 1/10
So you should get 6.6 %

The expression y2 – 10y + 24 has a factor of y – 4. What is another factor of y2 – 10y + 24? y – 20 y – 14 y – 8 y – 6
Answers
Answer:
y - 6
Step-by-step explanation:
Given
y² - 10y + 24
Consider the factors of the constant term (+ 24) which sum to give the coefficient of the y- term (- 10)
The factors are - 4 and - 6, since
- 4 × - 6 = + 24 and - 4 - 6 = - 10, thus
y² - 10y + 24 = (y - 4)(y - 6)
Thus the other factor is (y - 6)
(y - 4) and ( y - 6 ) are the factors of the quadratic equation
What do you mean by quadratic equation?The equation ax2 + bx + c=0 in one variable, with a 0, is known as a quadratic equation. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.The answer could be simple or complicated.
The roots of the quadratic equations are
x = [-b ± √ (b² - 4ac)] / ( 2a ) ( 2a )
Since (b2 - 4ac) is positive, we have two real solutions where (b2 - 4ac) is the discriminant.
When the discriminant is 0, there is just one viable option (both answers are the same)
In the case of a negative discriminant, two complicated solutions are obtained.
Let the quadratic equation be expressed as A given the data.
Right now, A is valued at
y² - 10y + 24 be equation (1)
The quadratic equations' roots are
y = [ -b ± √ ( b^2 - 4ac ) ] / ( 2a )
y = 10 ± √ ( 100 ) - ( 4 ( 24 ) ) / 2
y = ( 10 ± √4 ) / 2
y = ( 10 ± 2 ) / 2
As a result, y has two values of 10 + 2 / 2 and 6
And , y = (10 - 2) / 2 y = 4
In addition, the variables in the equation are
( y - 4 ) ( y - 6 ) = y² - 10y + 24
The quadratic equation is therefore resolved.

The school athletic director had a budget of $500 to purchase 164 items
for the soccer team. She purchased vests for $2.50 each, soccer balls for
$9.25 each, and cones for $0.75 each. She purchased 40 more cones than
balls. How many of each item can purchase?
Answers
Answer: She purchased 72 cones, 32 balls, and 60 vests.
Step-by-step explanation:
The total number of items is 164.
The price of the vests is $2.50 each.
The price of the soccer balls is $9.25 each.
The price of the cones is $0.75 each.
The total budget was $500.
If V is the number of vests, B the number of balls, and C the number of cones, we have that:
V + B + C = 164.
V*$2.50 + B*$9.25 + C*$0.75 = $500.
and:
"She purchased 40 more cones than balls."
C = B + 40.
Then we have a system of 3 equations and 3 variables:
V + B + C = 164.
V*$2.50 + B*$9.25 + C*$0.75 = $500.
C = B + 40.
Here the first step is to replace the third equation into the other two, in this way we eliminate one variable and one equation:
V + B + (B + 40) = 164
V*$2.50 + B*$9.25 + (B + 40)*$0.75 = $500.
Now we want to isolate one variable in one of the equations, i will isolate V in the first equation:
V = 164 - 2*B - 40 = 124 - 2*B
Now i can replace this into the other equation:
(124 - 2*B)*$2.50 + B*$9.25 + (B + 40)*$0.75 = $500
Now let's solve this for B.
$310 - $5*B + B*$9.25 + B*$0.75 + $30 = $500
B*( $9.25 - $5 + $0.75) = $500 - $310 - $30
B*$5 = $160
B = 160/5 = 32
Now we know the value of B.
And by the equations above:
V = 124 -2*B = 124 - 2*32 = 60
C = B + 40 = 32 + 40 = 72.
Then:
She purchased 72 cones, 32 balls and 60 vests.
My lawn is 17ft wide and 20ft long, each square foot of lawn gets 1350 new snowflakes per min how much snow in kilograms accumulates every hour average mass of snowflake is 1.70mg
Answers
Answer:
46.818 kg
Step-by-step explanation:
First, find the surface area of your yard. This is found by multiplying the length and width.
The equation for this is (l*w)=sa
So,
l=20ft
w=17ft
(20*17)= 340 square feet.
So, if each square foot gets 1350 new flakes per minute, you are going to find how much the entire yard gets in a minute by multiplying the surface area by 1350.
So,
(340*1350)= 459000 flakes for the entire yard in one minute.
Since there is 60 minutes in an hour, multiply 459,000 by 60.
459,000*60= 27,540,000 new flakes in the yard per hour.
Now, to find the weight in milligrams:
27,540,000*1.7= 46,818,000 mgs
Finally, because a kilogram is equal to one million milligrams (mg),
46,818,000/1,000,000= 46.818 kg

Calculate the average speed between 0 s and 20 s
Answers
Answer:
2 m/s
Step-by-step explanation:
Notice that the slope of the time period from 0s to 20s is linear. This means we can simply look at the distance traveled over the amount of time. So the distance and time both start at 0. At 20s, the distance is 40m.
So we can say the following to find the slope:
(40m - 0m) / (20s - 0s) == 40m / 20s == 2 m/s
Hence, the average speed between 0s and 20s is 2m/s.

What is Unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Payment for one hour = $8.95
So, paid for 40 hours
=40*$8.95
= $358.00
Now for -a-half overtime
=$8.95*1.5
= $13.425
Now, for extra 9.5 hours
=$13.425*9.5
=$127.5375
Hence, Irving’s time-and-a-half pay rate an hour
=127.5375+358.00

¿Cuántas libras de café “La Finca” que se vende a $5 la libra debe mezclarse con 80 libras decafé común que se vende a $2 la libra, para hacer una mezcla que se venda a $3 la libra?
Answers
Answer:
Necesitamos agregar 40 libras del café La Finca
Step-by-step explanation:
Sea x el número de libras de café de La Finca a mezclar.
Entonces, la cantidad total de libras que obtendremos en la mezcla será (x + 80) libras.
Ahora trabajemos con los precios; Tenemos x libras de La Finca a $ 5 por libra, con 80 libras de café a $ 2 por libra para dar una mezcla de (x + 80) a $ 3 Así, sumaremos el precio de La Finca más la otra variante para llegar al costo de la nueva mezcla.
Matemáticamente;
5 (x) + 2 (80) = 3 (x + 80)
5x + 160 = 3x + 240
5x -3x = 240-160
2x = 80
x = 80/2 x = 40
There are 6 black marbles, 14 blue marbles, 8 white marbles,
and 12 clear marbles in a bag. If Andy chooses a second marble
without replacing the first marble, what is P(black, then clear)?
Answers
Answer:
3/65 = 0.046 = 4.6%
Step-by-step explanation:
Notice that the total number of marbles is:
6 + 14 + 8 + 12 = 40
Then , the probability of getting a black marble first is 6/40 = 3/20
Now, since the experiment is without replacing, he is left with a total of 39 marbles in the bag, and the probability of getting a clear one is now 12/39
The total probability is the product of these two:
(3/20) x (12/39) = 3/65 = 0.046 = 4.6%
