To celebrate the first day of school, Emma brought in a tray of caramel brownies and walnut brownies. The tray had a total of 30 brownies, of which 90% were caramel. How many caramel brownies did Emma bring?

Answer:

     x ≈ 67.1

Step-by-step explanation:

The side adjacent to x° is given, along with the hypotenuse. That suggests the relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(x°) = 28/72 = 7/18

The angle is found from the cosine using the inverse cosine function:

  x° = arccos(7/18)

  x° ≈ 67.1°

The height of the flagpole to the nearest hundredth is 11.41 m

In order to get the height of the flagpole, we will use the similarity theorem of shapes.

From the given diagram, we will have the expression

1.65/1.15 = x/7.95

Cross multiply

1.15x = 1.65 * 7.95

1.15x = 13.1175

x = 13.1175/1.15

x = 11.406

Hence the height of the flagpole to the nearest hundredth is 11.41 m

Answer:

11.8 m:

Step-by-step explanation:

Volume = pi×r²×h
95 = pi×1.6²×h
h = 95/(pi×1.6²)
h = 11.8122809326
h = 11.8 m (nearest tenth)

Answer:

11.8 m:

Step-by-step explanation:

Volume = pi×r²×h

95 = pi×1.6²×h

h = 95/(pi×1.6²)

h = 11.8122809326

h = 11.8 m (nearest tenth)

Answer number 2

Answer:

d) 35ft

e) 6 seconds

f) 250°

Step-by-step explanation:

If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.

   36 secs = 360°

⇒ 1 sec = 360/36 = 10°

d)  After 9 seconds, it has turned:

9 x 10 = 90°

Therefore, it will be 15 + 20 = 35ft from the wall

e) 60° = 6 seconds

f) 25 seconds = 25 x 10 = 250°

Given :-

To Find :-

Solution :-

Here the cost price for Raj is Rs 400 and Selling price is Rs420 .

Here since SP > CP , so there's a profit .

→ Profit = SP - CP

→ Profit = Rs420 - Rs400

→ Profit = Rs 20

Now we can calculate the profit% as ,

→ Profit/CP * 100

→ Rs 20/ Rs 400 * 100 %

→ 20/4%

→ 5%

Hence the profit is 5% .

I hope this helps .

Answer:

Step-by-step explanation:

Cost price of the article = Rs 400

Selling price of the article = Rs 420

As, S.P > C.P

Profit = S.P – C.P

= Rs( 420 – 400)

⠀⠀⠀= Rs 20

So,

Profit percent = (20/400 × 100)%

⠀⠀⠀⠀⠀⠀⠀⠀ = (20/4) %

⠀⠀⠀⠀⠀⠀⠀⠀ = 5 %

percentage is a ratio of a number or fraction to 100

percentage =per(every) + cent (100)

per cent = per 100

percentage calculation formula (%) = (part / whole ) ×100

percentage increase equation = 100 ×( final - initial) /initial

ex1 : 2% is 2 percent = 2/100 =2:100

ex2: 35% = 35/100

48% = 48/100

ex3 : find the following 10% of 25,000

step 1 : convert 10% into fraction = 10/100

step 2 : multiply the fraction with value = 10/100× 25,000

answer = 2,500

ex4 : what is 7% of 68m ?

step 1 : convert 7% into fraction = 7/100

step 2 : multiply the fraction with value = 7/100 × 68

answer = 4.76 m

ex5 : The original price of a shirt was $10. It was decreased to $5 . What is the percent decrease of the price of this shirt?

step 1 : find the amount decreased = $10–$5 =$5

step 2 : write as part / whole = $5 / $10 = $0.5

step 3 : multiply by 100 = 0.5 × 100 = 50%

ex6 : Mary has a monthly salary of $21,000. She spends $350 per month on food. What percent of her monthly salary does she spend on food?

step 1 : write as part /whole and multiply by 100

= ( 350 / 21000 ) ×100 = 1.7 %

ex6 : The price of a pair of shoes was decreased by 21% to $100. What was the original price of the trousers?

step 1 : write % as fraction = 21/100

original price = y

(y × 21/100 ) = amount decreased --------- 1

y - amount decreased = $100 -------------- 2

rearrange equation 2 as;

y - $100 = amount decreased -------------- 3

when you equate both equation 1 and 3 you should get the ans y = $ 126.58

ex6 : The price of an item changed from $120 to $100. Then later the price decreased again from $100 to $80. Which of the two decreases was larger in percentage term?

step 1 : part / whole = (120 - 100) / 120 = 0.17 = 17%

step 2 : part / whole = (100 - 80) / 100 = 0.20 = 20%

The part were the same in both cases but the whole was smaller in the second decrease.

ex7 : A family had dinner in a restaurant and paid $35 for food. They also had to pay 9.5% sale tax and 10% for the tip. How much did they pay for the dinner?

for food = $35

sale tax = 9.5/100 × 35 = $3.33

tip = 10 /100 × 35 = 3.5

total = $45.83

ex8 : Smith invested $5000 for two years. For the first year, the rate of interest was 7% and the second year it was 8.5%. How much interest did he earn at the end of the two year period?

Answer

Interest at the end of the first year

7/100 * 5000 = $350

Interest at the end of the second year

8.5/100 * (5000 + 350) = $454.75

Total interest at the end of the two year period is

$350 + $454.75 = $804.75

Answer:

[tex] x\ intercept = (-8,0)\\\\ y\ intercept = (0,-4)[/tex]

Step-by-step explanation:

A equation is given and we need to find out the x and y intercept . The given equation is ,

[tex]\longrightarrow -2x + 4y =-16[/tex]

In order to find out the y intercept , substitute x = 0 in the given equation,as;

[tex] -2x + 4y =-16\\\\\longrightarrow -2(0)+4y =-16\\\\\longrightarrow 4y = -16\\\\\longrightarrow y =\dfrac{-16}{4}\\\\\longrightarrow y = -4 [/tex]

Again to find x intercept substitute y = 0 in the given equation, as ;

[tex]\longrightarrow -2x + 4y = -16 \\\\\longrightarrow -2x +4(0)=16\\\\\longrightarrow -2x = 16\\\\\longrightarrow x =\dfrac{16}{-2}\\\\\longrightarrow x =-8[/tex]

This is the required answer !

Step-by-step explanation:

Add the ones with like terms.

which means the ones with things in common.

4/5x^2 + 1/4x^2 i'm adding this first because we have x^2 on both sides.

(4/5 + 1/4)x^2

= (5+16/20)x^2

= (21/20)x^2

the next terms are those with x as common.

(1/4 +- 1/5)x...take the sign into consideration while dealing with the terms within the equations.

=(1/4 - 1/5)x

=(5 - 4/ 20)x

= (1/20)x

= (1 × x) / 20

= x/20.

last ones are the constant terms(numbers)

1/6 + 2/3

=12 + 3 / 18

= 15/18...we can simplify this one as well.

= 5 × 3 / 6 × 3

= 5/6.

Now write all the results as a one equation.

descending order starting from the highest degree which is 6/5x^2 --> 1/20x ---> 5/6.

21/20x^2 + x/20+ 5/6.

Step-by-step explanation:

Answer:

(3, -6)

Step-by-step explanation:

Both equations are equal to y, so you can make them equal to each other:

-2x = 5x-21

Get the same terms on the same side by subtracting 5x from both sides"

-7x = -21

Get x alone by dividing both sides by -7:

x = 3

The simplest way to find y is by filling in 3 for x in the first equation:

y = -2(3)

Multiply:

y = -6

Check your answer by filling in 3 for x in the second equation:

y = 5(3) - 21

Multiply:

y = 15 - 21

Subtract:

y = -6

To check both answers together, fill in 3 for x and -6 for y in both equations (although we already checked both answers above):

-6 = -2(3)

-6 = -6

-6 = 5(3) - 21

-6 = 15 - 21

-6 = -6
