Answer:

B. 7√2

Step-by-step explanation:

One of the trigonometry formulas to find a missing side is:

sin θ = opp/hyp

Substituting those values in with the ones we have, we will get:

sin (45deg) = x/14

√2/2 = x/14

14(√2/2) = x

x = 7√2

3.  a. 6:2 and 9:3

    b. 3:2 and 1:3

Step-by-step explanation:

1.  circle every 3 mustard seeds, 5 chili power and 1 salt

2. So draw two circles and five squares to represent 1 batch of chocolate milk and to represent 2 do the same thing (make sure to circle the two separate batches)

Answer:

Step-by-step explanation:

3 angles in a triangle always add up to be 180.
So, angle prq = 180 - 49 - 80 = 51

Angle qrx is supplementary to prq => angle qrx = 180 - 51 = 129

Answer:

2:27 PM.

Step-by-step explanation:

4:35 PM - 2hr 8 min

(35 - 8 = 27

4 - 2 = 2)The subtraction. It doesn't work like these 2 everytime.

= 2:27 PM.

[tex]Answer:[/tex]

No. They are not equivalent because sure, we can multiply them by 5,000 to get these 2 numbers, but 7 is not divisible by 5,000

Therefore, they are not equivalent ratios.

Answer: Picking the first option and constantly adding on and on you will eventually make way more than what the second option proposes, therefore picking the first option is the obvious choice.

Step-by-step explanation:

Well let’s see it starts off slow for instance 1, 2, 4, 8, 16 and so on adding that on for a month will eventually leave you with more.

Answer:

y = ½x + 5

Step-by-step explanation:

slope of the line is : a= (8-5)/(6-0) = ½ it's the coefficient of x too.

y = ax + b → y = ½x + b

consider the point (0,5) → 5 = ½(0) + b → b = 5

so equation of the line is: y = ½x + 5

Answer:

Step-by-step explanation:

(6,8)  ; (0,5)

At y-intercept x is o.

y=intercept = b = 5

Equation of line in slope intercept form: y = mx + b

y = mx + 5

In this, Plugin the values of the point (6 ,8)

8 = 6m + 5

8 - 5 = 6m

3 = 6m

Divide both sides by 6

3/6 = 6m/6

1/2 = m

Equation of the line:

[tex]y = \dfrac{1}{2}x+5[/tex]

Answer:

2 ounces

[tex]0.125*16=2[/tex]

Multiply mass by 16 to find.

Answer:

A

Step-by-step explanation:

3/4*(-4/3) + 1/2 = -1 + 1/2 = -1/2

First, B is not the answer, because if x = 0, the whole equation would've been 0.

A) -4/3 ; -1/2

Replace x and y with the 2 fractions, we have : 3/4 x (-4/3) + 1/2 = -1/2
-1 + 1/2 = -1/2 (true)
So, A is correct

But to make sure, we'll go over C and D also.

C) 4/3 ; 1/2

Replace x and y : 3/4 x 4/3 + 1/2 = 1/2
1 + 1/2 = 1/2 (not true)

So this is not the answer

D) 4 ; 3/2

Replace x and y : 3/4 x 4 + 1/2 = 3/2
3 + 1/2 = 3/2 (not true)

So, A is correct.

Answer:

y=25,000(0.89)^6

Step-by-step explanation:

Answer:

a: y= 25,000(0.89)^6

Step-by-step explanation:

Hey there!

[tex]|\displaystyle\frac{x-1}{2} |=7[/tex]

Let's say that x-1 is negative:

[tex]\displaystyle\frac{-x+1}{2} =7[/tex]

The first step is to multiply both sides by 2:

[tex]\text{-x+1=14}[/tex]

Now, move 1 to the right, using the opposite operation:

[tex]\text{-x=14-1}[/tex]

[tex]\text{-x=13}[/tex]

Divide both sides by -1:

[tex]\text{x=-13}[/tex]

I hope you find my answer helpful.

Good luck!

Have a great day!

The equivalent values for the ratio 2 to 3 to 8 is 28kg, 42kg and 112kg

Given the following parameters

Total weight = 182kg

If the weight is divide in the ratio 2:3:8, th3n the total ratio will be;

total ratio = 2 + 3 + 8

Total ratio = 13

For the ratio of 2;

Portion =2/13 * 182

Portion = 28kg

For the ratio of 3;

Portion =3/13 * 182

Portion = 42kg

For the ratio of 8;

Portion =8/13 * 182

Portion = 112kg

Hence the equivalent values for the ratio 2 to 3 to 8 is 28kg, 42kg and 112kg

Answer:  2

Step-by-step explanation:

The circumference of a circle is 2*radius*pi.

We can set up an equation as we know the circumference as 4pi.

4pi = 2*radius*pi

Divide both sides by pi:

4 = 2*radius

Divide both sides by 2:

radius = 2

Answer:

2 ft

Step-by-step explanation:

The equation for circumference is:

[tex]C=2\pi r[/tex]

We can plug in the given value for circumference to solve for the radius.

[tex]4\pi=2\pi r[/tex]

Divide both sides by 2π

[tex]\frac{4\pi}{2\pi}=r\\r=2\ ft[/tex]

Answer:

6. C. 4x-7

7. B. 417.6

8. 138.98

Explanation:

6) (7x-5) - (3x-2)

7x-5 - 3x+2

distribute the -1 from the middle into (3x-2) which only changes the signs

7x-5 - 3x+2

collect like terms (7x and -3x) as well as (-5 and 2)

Answer---> 4x-3

7) 0.5x+78.2=287

-78.2 -78.2

move the constant to the right side and change it's sign

0.5x=287-78.2

--> 0.5x= 208.8

Subtract the numbers on the right hand side

0.5x= 208.8

------ --------

0.5x 0.5x

divide both side of the equation by 0.5

8) Given: Graham's monthly bank statement with deposits and withdrawals:

-25.20,−25.20,52.75,-22.04,−22.04,-8.50,$94.11

If Graham's balance in the account was $47.86 at the beginning of the month .

Then the account balance at the end of the month =

=47.86+(-25.20+ 52.75- 22.04- 8.50+ 94.11)

=47.86+(52.75 + 94.11 − 25.20− 22.04− 8.50)

=47.86+(146.86− 55.74)

47.86+(91.12)=47.86+91.12= 138.98

Thus, the account balance at the end of the month= $138.98

Answer:

The radius of the circle is about 5

Step-by-step explanation:

The formula for the radius of the circle with a area is:

- R= the square root of the area divide by pi ( π)

or - R= the square root of A/ π

Plug in 78.5 into the formula

then you get the radius which is 5.

Answer:

x = 20; angles = 58°

Step-by-step explanation:

Since the given triangle is an isosceles triangle & the 2 opposite angles are equal, then even the opposite angles of the equal opposite sides will be equal.

So,

3x - 2 = x + 38

3x - x = 38 + 2

2x = 40

x = 40/2

x = 20

Angles:

■ 3x - 2

= 3(20) - 2

= 60 - 2

= 58°

■ x + 338

= 20 + 38

= 58°

=》Both the angles are equal & each measure 58°
