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 [12381]

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.

Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to
AnnZ [12381]

Response:

9.55 minutes

Step-by-step breakdown:

x hours to reach the river

0.25-x hours for the return trip, as 15 minutes equals 0.25 hr.

to the river 40 mph * x hours =40x miles

from the river 70 mph (0.25-x) hours=17.5-70x

these two equations are equivalent

40x=17.5-70x

110x=17.5

x=17.5/110=0.159 hours

9.55 minutes

A health department spokesman speaking on a local radio station has advocated that parents download a particular app on their ph
AnnZ [12381]

Response:

Option E is the right choice.

A connection seems evident between the app and the reduction of daycare-related illnesses.

Step-by-step breakdown:

Research involved 1200 randomly chosen parents, revealing that the kids of parents who utilized the app had an average of 10 fewer cases of daycare illnesses compared to those whose parents didn’t download it during the study duration.

Reviewing the options individually

a. Since using the app appears to lower child sickness, its effectiveness should extend to decreasing child neglect as well.

The study indicates a reduction in daycare-related illnesses for those using the app but does not address neglect, making this conclusion incorrect.

b. Using the app will ensure daycare employees do not transmit germs.

The research didn't examine how the app functions, nor whether it stops daycare workers from transmitting germs. Thus, this conclusion lacks accuracy.

c. The analysis was performed as an experiment, not an observational study.

In reality, it was primarily observational. Such studies document results without manipulation by the researchers.

d. The sample size of the study was inadequate for drawing conclusions.

A pool of 1200 is sufficiently large to reflect the wider population’s characteristics. Therefore, this assertion is also incorrect.

e. A link seems to exist between the app and reduced transmission of daycare illnesses.

From the provided details, it’s clear that the findings of this study depict a link between using the app and a marked decrease in daycare-related illnesses among children of those who have downloaded it. Hence, the app likely plays a role in lowering the risk of such illnesses in their children.

Hope this is helpful!

5 Adoncia makes a scale drawing of the front of
zzz [12365]

Answer:

Due to the drawing measuring 200 ft., which translates to 13.33 in. with a scale of 15 ft to 1 in., and given that the sheet of paper is 11 in. long, Adoncia's depiction will not fit onto the paper.

Step-by-step explanation:

The provided details include;

The scale is 15 ft = 1 in.

The actual monument's dimensions;

Height = 80 ft.

Length = 200 ft.

Hence, we can establish;

The necessary paper height = 80/15 = 16/3 = 5.33 in.

The necessary paper length = 200/15 = 40/3 = 13.33 in.

As the paper size provided is 11 in., which is standard at 8.5 in. by 11 in.,

The drawing length of 13.33 in. exceeds the available paper length of 11 in.

Thus, Adoncia's drawing will not fit on the paper.
