Answer:

Step-by-step explanation:

I arrived at 2 because you can move both leftward and rightward. Negative values are located to the left of 0, whereas positive values appear to the right. Moving 10 units to the right of 0 results in 10, while moving 10 units to the left of 0 gives -10.

I hope this clarifies things for you! If there are any inaccuracies, please let me know, as that would be very helpful.

Michael uses a blend of dark chocolate and milk chocolate to make the ice cream topping at his restaurant. He needs to buy 100\,

AnnZ [9104]

Answer:

Michael purchases 60 kg of dark chocolate alongside 40 kg of milk chocolate.

Step-by-step explanation:

Let d signify the kilograms of dark chocolate bought by Michael and m signify the kilograms of milk chocolate he acquires.

He must acquire a total of 100 kg of chocolate, thus

$d+m=100$

With dark chocolate priced at $12 per kg, the cost for d kg would be $12d. The price of milk chocolate is $10 per kg, indicating the cost for m kg is $10m. Michael intends to spend $1,120 on the chocolate, therefore

$12d+10m=1,120$

Taking the first equation

$d=100-m$

By inserting this into the second equation:

$12(100-m)+10m=1,120\\ \\1,200-12m+10m=1,120\\ \\-12m+10m=1,120-1,200\\ \\-2m=-80\\ \\m=40\\ \\d=100-m=100-40=60$

Michael ends up buying 60 kg of dark chocolate and 40 kg of milk chocolate.

A 16\dfrac1216 2 1 16, start fraction, 1, divided by, 2, end fraction kilometer stretch of road needs repairs. Workers can rep

lawyer [9240]

Answer:

The repair of the stretch of road will require

weeks to finish. $7\frac{1}{3}$

Step-by-step explanation:

Provided:

Length of the roads needing repair =

Length of the road workers can fix in a week = $16\frac{1}{2}\ km$

To ascertain how many weeks it will take to mend this road stretch. $2\frac{1}{4}\ km$

Solution:

Worker's road repair rate = per week.

Overall road length to repair =

$2\frac{1}{4}\ km$

The time required to repair $16\frac{1}{2}\ km$

of road by the workers can be calculated: $16\frac{1}{2}\ km$ ⇒

When dividing mixed numbers, we change them first into fractions. $\frac{16\frac{1}{2}\ km}{2\frac{1}{4}\ km}$

To compute fraction division, we take the reciprocal of the divisor and substitute division with multiplication:

⇒ $\frac{\frac{33}{2}} {\frac{9}{4}}$

We revert the fraction back into a mixed number.

Thus, it will take

weeks to complete the road repair task. $\frac{33}{2}\times \frac{4}{9}$

Twelve of the 20 students in Mr. Skinner’s class brought lunch from home. Fourteen of the 21 students in Ms. Cho’s class brought

Svet_ta [9518]

Solution:

In Mr. Skinner's class, the count of students bringing lunch from home is 12 out of 20.

Fraction of students who brought lunch from home in Mr. Skinner's class= $\frac{12}{20}=\frac{3}{5}$

For Ms. Cho's class, the number who brought lunch from home is 14 out of 21.

Fraction of students who brought lunch from home in Ms. Cho's class= $\frac{14}{21}=\frac{2}{3}$

Siloni is utilizing two spinners with 15 equal sections to randomly select students from the classes and predict whether they brought lunch or will purchase it from the cafeteria.

Number of Equal sections in each Spinner=15

To visualize the students from Mr. Skinner's class who brought lunch using a Spinner with 15 equal sections = $\frac{9}{15}$

For Ms. Cho's class, using a Spinner with 15 equal sections = $\frac{10}{15}$

Mr. Skinner's Class +1 = Ms. Cho's Class

This means that the spinner for Ms. Cho's class will include one additional section representing students who brought lunch.

Option A signifies that one additional section on Mr. Skinner's spinner represents students who brought lunch, reflecting Ms. Cho's class.
