Answer:

Step-by-step explanation:

You can start by "filling up" all of the bigger boxes. 75*14=1050 cupcakes, which when subtracted from the total initial amount leaves 400 cupcakes for the smaller boxes. The smallest multiple of 13 smaller than 400 is 390, which is 10 smaller than 400. Therefore, there will be 10 cupcakes left over, or answer choice C. Hope this helps!

What are the integer solutions to the inequality below? 3 ≤ 3 x − 4 ≤ 2 x + 1

Nimfa-mama [501]

Answer:

$x$ can be $3$ , $4$ , or $5$

Step-by-step explanation:

Let's split the inequality and solve it piece by piece.

Case: $3$

We add $4$ to both sides to get $7$ .

We divide both sides by $3$ to get $7/3$ .

So, $x>=7/3$ .

Case: $3x-4$

We subtract 2x from both sides to get $x-4$ .

We add $4$ to both sides to get $x$ .

So, we want to find the integer solutions to $7/3$ .

$7/3= 2 1/3$ , so $x$ can be $3$ , $4$ , or $5$ .

So, $x$ can be $3$ , $4$ , or $5$ and we're done!

which equation describes a line that passes through (-5,-8) and is perpendicular to y=5/4x+10A. y=-0.8x+10B. y=-1.25x-14.25C. y×

Lesechka [4]

Let's begin by listing out the information given to us:

$(x,y)=(-5,-8)$

This is perpendicular to the line

$y=\frac{5}{4}x+10$

The equation is already in the slope-intercept form:

$\begin{gathered} y=\frac{5}{4}x+10 \\ slope(m)=\frac{5}{4} \end{gathered}$

The slope of the parallel line is given by:

$\begin{gathered} m(perpendicular)=-\frac{1}{m} \\ m=\frac{5}{4} \\ m(perpendicular)=-\frac{1}{\frac{5}{4}}=-\frac{4}{5} \\ m(perpendicular)=-\frac{4}{5}=-0.8 \end{gathered}$

We proceed by substituting the values of x & y into the new equation, we have:

$undefined$

For this item, a non-integer answer should be entered as a fraction using / as the fraction bar.

Kipish [7]

The numerical expression, 2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3 = <u>67/24</u> on simplification using the BODMAS rule.

In the question, we are asked to simplify the numerical expression:

2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3.

To simplify the expression, we will follow the BODMAS rule, where B means Brackets, O means Of, D means Divide, M means Multiplication, A means Addition, and S means Subtraction.

2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3

= 2/3 ÷ 16 + (3/4 + 1/6) ÷ 1/3 {Solving 2⁴ = 16, before proceeding BODMAS}.

= 2/3 ÷ 16 + ((9+2)/12) ÷ 1/3 {Solving Brackets by taking LCM}

= 2/3 ÷ 16 + 11/12 ÷ 1/3 {Simplifying}

= 2/3 * 1/16 + 11/12 * 3/1 {Solving divisions by taking reciprocals}

= 1/24 + 11/4 {Multiplying}

= (1 + 66)/24 {Adding using LCM}

= 67/24 {Simplifying}.

Thus, the numerical expression, 2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3 = <u>67/24</u> on simplification using the BODMAS rule.

The point (-7,4) in on the terminal side of an angle t. Find sec (t) to two decimal places.

Sliva [168]

Answer:

-1.15

Step-by-step explanation:

The tangent of the angle can be found as ...

tan(t) = (y-coordinate)/(x-coordinate) = -4/7

The secant of the angle is related by ...

sec(t)² = tan(t)² +1 = (-4/7)² +1 = 65/49

Then the secant of this 2nd-quadrant angle is ...

sec(t) = -√(65/49) = -(√65)/7 ≈ -1.15
