Answer:

They sold 120 milkshakes that day

Step-by-step explanation:

We can set up a proportion

$\frac{48}{m} \: = \frac{2}{5}$

48 × 5 = 2m

2m = 240

m = 120

Note: If you have some value, , and it is of the total amount, you can find the value by doing the equation

$\frac{v}{x} \times 100$

For #1. 3x + x +7 = 180 degrees
4x + 7 = 180
4x = 173
so x = 43.25

For #2. 2x + 5 = 110 degrees
2x = 105
so x = 52.5

For #3. 1 and 3, 2 and 4, 5 and 8, 6 and 7.

What is sec 0 when tan 0 = V3? Đ. (1, 0) sec 0 = [?]

adoni [48]

Answer:

secθ = - 2

Step-by-step explanation:

Using the identity

sec²θ = 1 + tan²θ

= 1 + ( $\sqrt{3}$ )² = 1 + 3 = 4 ( take the square root of both sides )

secθ = ± $\sqrt{4}$ = ± 2

Since secθ < 0 in the third quadrant , then

secθ = - 2

What is the value of y in the solution to the system of equations?<br> *x+3y=1<br> 2x – 3y = -30

Delvig [45]

Answer:

$\large\boxed{y=\dfrac{32}{9}}$

Step-by-step explanation:

$\underline{+\left\{\begin{array}{ccc}x+3y=1\\2x-3y=-30\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad3x=-29\qquad\text{divide both sides by 3}\\.\qquad x=-\dfrac{29}{3}\\\\\text{put the value of x to the first equation}\\\\-\dfrac{29}{3}+3y=1\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\left(-\dfrac{29}{3\!\!\!\!\diagup_1}\right)+(3)(3y)=(3)(1)\\\\-29+9y=3\qquad\text{add 29 to both sides}\\\\9y=32\qquad\text{divide both sides by 9}\\\\y=\dfrac{32}{9}$
