If sec 50 = cosec 70, prove that 0 = 7.5°​

Answers

Answer 1

Answer:

The proofing is given below:

Step-by-step explanation:

[tex]Sec 5\theta = cosec 7\theta\\\\cosec (90 - 5\theta) = cosec 7\theta\\\\Now\ on\ comparision \\\\90 - 5\theta = 7\theta\\\\90 = 7\theta + 5\theta\\\\90 = 12\theta\\\\\frac{90}{12} = \theta\\\\0.75 = \theta[/tex]

Hence, it is proved

If Sec 50 = Cosec 70, Prove That 0 = 7.5

A factory makes 450 pies every day.
The pies are chicken pies or steak pies.
Each day Milo takes a sample of 15 pies to check.
The proportion of the pies in his sample that are chicken is the same as the proportion
of the pies made that day that are chicken.
On Monday Milo calculated that he needed exactly 4 chicken pies in his sample.
Work out the total number of chicken pies that were made on Monday.​

Answers

Step by step:

Each day it takes a sample of 15 pies - on Monday he needed 4:

4/15 = x/450 (450 being the total for each day)

4 x 450 = 1800
1800 divided by 15 = 120

120 is the amount of pies that were made on Monday

Find the surface area of the rectangular prism.

Answers

First of all I wanna point out a minor mistake!

this is not a rectangular prism, the base of this picture is actually the side facing us and the back side. Making this a triangular prism.

We can start by finding the 2 triangles which are the bases.

Each triangle have area:10*24/2

Now because there are 2 same triangles we can get rid of the /2 and get the area of the triangles in the diagram is 10*24=240

We could do the other three sides 1 by 1, let's start with the side on the left of the shape. It has area 24*19=456 because the bottom is a rectangle so we could just use the 19.

Now we can do the side that is diagonal and on the right. It has area of 26*19=494.

Now just 1 more side the bottom, it has area of 10*19=190. Everything is in cm^2 as a unit because we are dealing with area.

Now we just need to add everything together.

240+456+494+190= 1380

Hope it helps! any questions about my answer please just leave in the comment I will get to it when I have time.

Answer:

your answer is 1380

Step-by-step explanation:

A quadratic equation has a
discriminant equal to 5. What
does this tell you about the
solution(s) to the equation?

Answers

Answer:

[tex]\boxed {\boxed {\sf 2 \ real \ solutions }}[/tex]

Step-by-step explanation:

The quadratic formula is:

[tex]{x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}[/tex]

The discriminant of a quadratic is just the expression under the square root, or [tex]b^2-4ac[/tex]. This can tell us the number of solutions a quadratic has.

If the discriminant is:

Positive = 2 real solutions Equal to Zero = 1 real double/repeated solution Negative = 0 real solutions, but 2 imaginary solutions

Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.

Answers

Answer:

the first one is 57

the second one is 60

3rd one is 13

4th one is 9

Step-by-step explanation:

hope this helps :) have a nice day !!

**please let me know if this was wrong**

Answer:

1) In the second step, it was supposed to multiply 9 and 2 and 36 by 3 instead of adding 9 and 3 to each other because multiplication and division comes before adding, according to pemdas.  

2) In the second step, they were supposed to multiply 6 and 4 instead of subtracting 27 and 6 because multiplication comes before subtraction, according to pemdas.

3)

(43 - 20) - 2 · 5

43 - 20 = 23

23 - 2 · 5

2 · 5 = 10

23 - 10 =

13

4) 81 ÷ (13 - 4)

13 - 4 = 9

81 ÷ 9

81 ÷ 9 =

9

5) 7 · 8 - 3 · 6 + 1

7 · 8 = 56

3 · 6 = 18

56 - 18 + 1

56 - 18 = 38

38 + 1 =

39

6)

7)

8)

Step-by-step explanation:

Section 1: Explain the error in each problem below.

1) Pemdas says multiplication and division comes before adding, so you must solve the multiplication in the problem first before the addition.  

2) Again, as pemdas says, multiplication comes first before subtraction, so you must solve the multiplication in the problem first before the sutraction.

Section 2: Simplify the following expressions.

3) (43 - 20) - 2 · 5

Pemdas says to solve the parenthesis first.

43 - 20 = 2323 - 2 · 5

Now multiplication comes next (because there's no exponents).

2 · 5 = 1023 - 10

Now subtraction.

23 - 10 = 13

4) 81 ÷ (13 - 4)

Pemdas says to solve the parenthesis first.

13 - 4 = 981 ÷ 9

Now division comes next.

81 ÷ 9 = 9

5) 7 · 8 - 3 · 6 + 1

Pemdas says to solve the multiplication first.

7 · 8 = 56 3 · 6 = 1856 - 18 + 1

Now subtraction and addition.

56 - 18 = 3838 + 1 = 39

6)

Section 3: Insert grouping symbols to make the statements true.

Reena bought a mobile phone for 16,240 that included a GST of 12%. Find the price of the mobile phone before the GST was added.​

Person who answers will be marked brainliest

Answers

Answer: 14500

Step-by-step explanation:

Let the price of the mobile phone before the GST was added be represented by x.

Therefore,

x + (12% × x) = 16240

x + 0.12x = 16240

1.12x = 16240

x = 16240/1.12

x = 14500

The price of the mobile phone before the GST was added was 14500

Of those who like to fish, what percent are ages 13-18?

Answers

Answer:

B.) 42.9

Step-by-step explanation:

The percent that we are trying to find out is 12/28

I know this because if you add the 12 and 16 which is the total amount of people given then it leaves us with an amount of 28 people. Since we are trying to find the percent of the number of people who like fish we have to divide the total by 12 (the number of people who like fish)

Anyways 12 divided by 28 = 42.857etc.

If we simplify this then that gives us our answer of B.) 42.9

B. 42.9%
trust me it’s right
