Write and solve an equation to find the values of d and w .

Answers

Answer:

d = 65°

w = 55°

Step-by-step explanation:

m∠DAC +∠m∠CAB = 60

m∠DAC + 35 = 60

m∠DAC = 25

m∠DAC + d = 90

25 + d = 90

d = 65°

m∠GAF + w + d = 180

60 + w + 65 = 180

w + 125 = 180

w = 55°

Find the volume of the cone. Round your
to the nearest tenth.

Answers

Answer: 147.71 yard³

Step-by-step explanation:

The volume of a cone is calculated using the formula:

Volume = ⅓πr²h

where,

π = 3.14

r = Diameter/2 = 8.4/2 = 4.2

h = height = 8

Volume = ⅓ × 3.14 × 4.2² × 8

Volume = ⅓ × 3.14 × 17.64 × 8

Volume = 147.71 yard³

$1215 is deposited in account that pays 6.5% annual interest, compounded continuously what is the balance after 8 years?

Answers

Answer:

FV= A= $2,043.66

Step-by-step explanation:

Giving the following information:

Initial deposit= $1,215

Interest rate= 6.5% compounded continuously

Number of years= 8

To calculate the future value, we need to use the following formula:

A= P*(e^rt)

A= Future value

P= principal

r= rate of interest

t= time in years

A= 1,215*(e^0.065*8)

A= $2,043.66

A teacher working's day is 7 1/2 hours long. one certain day, he spent 3 1/2 hours teaching and 2 1/2 hours marking student assignment. What fraction did he spend (a) Teaching (b) Marking.​

Answers

Answer:

(a) 7/15

(b) 1/3

Step-by-step explanation:

(a) teaching:

(3 1/2) / (7 1/2) = (7/2) / (15/2) = 7/2 * 2/15 = 7/15

(b) marking:

(2 1/2) / (7 1/2) = (5/2) / (15/2) = 5/2 * 2/15 = 5/15 = 1/3

Cody has $7. He wants to

dogs (x) are $2 each.
Peanuts (y) are $1 each.
Which ordered pair is a
solution?
x + y 24
2x + y s7
1,1 or 1,3

Answers

Answer:    (1,3)

=====================================================

Explanation:

Note that the two shaded regions overlap to form the darker shaded region. The point (1,1) is only in the green region, but not in the blue region. It needs to be in both regions for it to be a solution to the system. In contrast, the point (1,3) is on the boundary of the blue region and in the green region as well. It's a solution point because of this.

Points on the boundary are included because of the "or equal to" as part of the inequality sign. Hence the solid boundary lines rather than dashed boundary lines.

The solution (1,3) means that x = 1 and y = 3 pair up together. It says that Cody can buy x = 1 hotdog and y = 3 packs of peanuts so that he has at least 4 snacks, and he stays within the $7 budget.

Going back to (x,y) = (1,1) for a moment, this isn't a solution because x+y = 1+1 = 2 is not 4 or larger. In other words, he only buys 2 snacks here instead of 4 or more.

Step-by-step explanation:

To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.

The rectangle's area ([tex]lw[/tex]):

[tex]7.21*14=100.94[/tex]

The triangle's area ([tex]\frac{1}{2}bh[/tex]):

WILL MAKE BRAINLIEST!!!What are the practical results of the modern cult of beauty? The exercises and the massages, the health motors and the skin foods-to what have they led? Are women more beautiful than they were? Do they get something for the enormous expenditure of energy, time, and money demanded of them by the beauty cult? These are questions which it is difficult to answer. For the facts seem to contradict themselves. The campaign for more physical beauty seems to be both a tremendous success and a lamentable failure. It depends how you look at the results.It is a success insofar as more women retain their youthful appearance to a greater age than in the past. "Old ladies" are already becoming rare. In a few years, we may well believe, they will be extinct. White hair and wrinkles, a bent back and hollow cheeks will come to be regarded as medievally old-fashioned. The crone of the future will be golden, curly, and cherry-lipped, neat-ankled and slender. The Portrait of the Artist's Mother will come to be almost indistinguishable, at future picture shows, from the Portrait of the Artist's Daughter. This desirable consummation will be due in part to skin foods and injections of paraffin wax, facial surgery, mud baths, and paint, in part to improved health, due in its turn to a more rational mode of life. Ugliness is one of the symptoms of disease; beauty, of health. Insofar as the campaign for more beauty is also a campaign for more health, it is admirable and, up to a point, genuinely successful. Beauty that is merely the artificial shadow of these symptoms of health is intrinsically of poorer quality than the genuine article. Still, it is a sufficiently good imitation to be sometimes mistakable for the real thing. The apparatus for mimicking the symptoms of health is now within the reach of every moderately prosperous person; the knowledge of the way in which real health can be achieved is growing, and will in time, no doubt, be universally acted upon. When that happy moment comes, will every woman be beautiful-as beautiful, at any rate, as the natural shape of her features, with or without surgical and chemical aid, permits?The answer is emphatically: No. For real beauty is as much an affair of the inner as of the outer self. The beauty of a porcelain jar is a matter of shape, of color, of surface texture. The jar may be empty or tenanted by spiders, full of honey or stinking slime-it makes no difference to its beauty or ugliness. But a woman is alive, and her beauty is therefore not skin deep. The surface of the human vessel is affected by the nature of its spiritual contents. I have seen women who, by the standards of a connoisseur of porcelain, were ravishingly lovely. Their shape, their color, their surface texture were perfect. And yet they were not beautiful. For the lovely vase was either empty or filled with some corruption. Spiritual emptiness or ugliness shows through. And conversely, there is an interior light that can transfigure forms that the pure aesthetician would regard as imperfect or downright ugly.
