SO my cake usually cooks from the top but stays undercooked at the bottom. I used olive oil instead of butter, and I didn't add
Ludmilka [50]

Answer:

Step-by-step explanation:

If your cake looks done outside but remains uncooked/gooey in the center, it means that its not completely cooked. Always insert a skewer in the center of the cake towards the finishing time to see if it comes out clean. If it doesn't then cook for few minutes more, and check after 5-10 minutes.

The average American spent $8,508 on health care in 2011. The cost of health care is projected to rise about 5.8% per year for t
klio [65]
<h3>The projected amount the average American spent on health care in 2014  is $ 10075.91</h3>

<em><u>Solution:</u></em>

Given that,

The average American spent $8,508 on health care in 2011

The cost of health care is projected to rise about 5.8% per year for the years 2012-2022

<em><u>The increasing function is given as:</u></em>

y = a(1+r)^t

Where,

y is future value

a is initial value

r is growth rate in decimal

t is number of years

From given,

a = 8508

r = 5.8 \% = \frac{5.8}{100} = 0.058

t = 2011 to 2014 = 3 years

<em><u>Substituting the values, we get,</u></em>

y = 8508(1 + 0.058)^3\\\\y = 8508(1.058)^3\\\\y = 8508 \times 1.1842\\\\y = 10075.914 \approx 10075.91

Thus the projected amount the average American spent on health care in 2014  is $ 10075.91

one bouquet of flowers has 3 roses for every 5 carnations. other bouquet has 4 carnations for every 5 daisies. if both bouquets
Leno4ka [110]

Answer:

therefore the second bouquet will have more flowers , as it will have 25 daisies

Step-by-step explanation:

3 roses for every 5 carnations

5 daisies for every 4 carnations

we can solve this using cross multiplication

3 : 5

x : 20

5x = 60

x = 60/5

<em>x = 12</em>

meaning that for a bouquet that has 20 carnations there will be 12 roses

5 : 4

x : 20

4x = 100

<em>x = 25</em>

meaning that for a bouquet that has 20 carnations there will be 25 daisies.

<u>therefore the second bouquet will have more flowers , as it will have 25 daisies</u>
