Can someone help me asap thx

Answer:

Step-by-step explanation:

You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.

You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.

That leaves you with one unknown angle. ? = 180°-40°-55° = 85°

You can buy 10 magazines in $60.

A unit rate means a rate for one of something.

Given that, the cost of 4 magazines is $24.00

For 4 magazine → $24

So, for 1 magazine = 24/4 = $6

So, in $60,

60/6 = 10

Hence, you buy 10 magazines in $60.

radius of cone and hemisphere are the same

volume of half sphere=(1/2)*(4/3)*[tex]\pi r^{3}[/tex]

                                    =(1/2)*(4/3)*3.14*[tex]4^{3}[/tex]                       (4*4*4=64)

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:

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.

3) (43 - 20) - 2 · 5

Pemdas says to solve the parenthesis first.

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

Now subtraction.

4) 81 ÷ (13 - 4)

Pemdas says to solve the parenthesis first.

Now division comes next.

5) 7 · 8 - 3 · 6 + 1

Pemdas says to solve the multiplication first.

Now subtraction and addition.

Answer:

Part A- an= an-1-5.9

Part B- -18.5,-24.4

Step-by-step explanation:

y=2+3x

putting value on second equation we get..

x-2(2+3x)=-6

x-4+6x=-6

7x=-2

×=-2/7

& y=2+3(2/7)

y=2+0.87

y=2.87..Ans..

Answer:

x= 2/5

y= 3.2

Step-by-step explanation:

y-3x=2

y=3x+2

replace y with 3x+2 in second equation;

x-2(3x+2)= -6

x- (6x+4)= -6

x-6x-4= -6

-5x-4+4=-6+4

-5x= -2

x= 2/5

y=3x+2

y=(3×2/5) +2

y= 3.2

Answer: The length of the hypotenuse (c) is 5

Step-by-step explanation:

Use the Pythagorean Theorem

a² + b² = c²

a & b are the legs (b is the base)

c = hypotenuse

a = 4

b = 3

a² + b² = c²

4² + 3² = c²

16 + 9 = c²

25 = c²

√c² = √25

c = 5

y ----> the area (in square meters) left to paint

we know that

Hiro paint at a rate of 8 square meters per hour

The rate is equal to the slope of the linear equation

we have the point (3, 28) ---> After 3 hours of painting, he had 28 square meters left to paint.

therefore

Answer: Each pair of gloves costs $15 and each pair of hat costs $10.

Step-by-step explanation:

Let x = Cost per pair of gloves

y= Cost per hat.

As per given, we have

[tex]5x+2y=95 \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)[/tex]

Multiply (ii) by 2 , we get

[tex]8x+2y=140\ \ \ \ (iv)[/tex]

Eliminate (i) from (iv), we get

[tex]3x=45\\x=15[/tex]

Put this in (ii), we get

[tex]4(15)+y=70\\60+y=70\\y=10[/tex]

Hence, each pair of gloves costs $15 and each pair of hat costs $10.

Answer:

Answer:

They can have infineyely many solutions :)

The solution to the system of equation is (7, 2)

Using the simultaneous equation:

5x + 3y = 41

2x + 3y = 20

using elimination method

Subtract equation 1 from 2 to have:

5x - 2x = 41 - 20

3x = 21

x = 21/3

x = 7

Substitute x = 7 into equation 1 to get y

5x + 3y = 41

5(7) + 3y = 41

35 + 3y = 41

5y = 41 - 35

3y = 6

y = 6/3

y = 2

Hence the solution to the system of equation is (7, 2)
