Answer:

8 cookies left to be baked

Step-by-step explanation:

Len bakes 1/3 of 30 cookies

To find 1/3 of 30, divide 30 by 3 then multiply by 1:

$\implies \frac{30}{3} \times1=10 \times 1=10$

Therefore, Len bakes 10 cookies

<u>Sallesh</u>

Sallesh bakes 2/5 of 30 cookies

To find 2/5 of 30, divide 30 by 5 then multiply by 2:

$\implies \frac{30}{5} \times2=6 \times 2=12$

Therefore, Sallesh bakes 12 cookies

<u>Cookies left to bake</u>

To calculate how many cookies are left to bake, subtract the found number of cookies Len and Sallesh have baked from 30:

30 - 10 - 12 = 8

So there are 8 cookies left to be baked.

In the diagram, the measure of angle 8 is 124°, and the measure of angle 2 is 84°. A transversal intersects 2 lines to form 8 an

BARSIC [14]

Clockwise from the top left, the angles are ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7, ∠8 are 96°, 84°, 96°, 84°, 56°, 124°, 56°, 124° respectively. Then the correct option is A.

<h3>What is an angle?</h3>

Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

In the diagram, the measure of angle ∠8 is 124°, and the measure of angle ∠2 is 84°.

Angle ∠1 and ∠2 are supplement angles.

∠1 + ∠2 = 180°

∠1 + 84° = 180°

∠1 = 96°

Similarly, angles ∠7 and ∠8 are supplement angles.

∠7 + ∠8 = 180°

∠7 + 124° = 180°

∠7 = 56°

By the property of the opposite angles, we have

∠1 = ∠3 = 96°

∠2 = ∠4 = 84°

∠5 = ∠7 = 56°

∠6 = ∠8 = 124°

Clockwise from the top left, the angles are ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7, ∠8 are 96°, 84°, 96°, 84°, 56°, 124°, 56°, 124° respectively.

Then the correct option is A.

Ginger make pies and sells them for $14 each. What equation if y represents the money and x represents the number of pies sold

BlackZzzverrR [31]

Answer:

y = 14x

Step-by-step explanation:

The equation is as follows:

Let us assume x be the number of pieces sold

And, the y be the money

Also the selling price be $14 each

So, the equation is

y = 14x

Evaluate the Riemann sum for f(x) = 3x − 1, −6 ≤ x ≤ 4, with five subintervals, taking the sample points to be right endpoints.

Verdich [7]

Answer:

The Riemann sum equals -10.

Step-by-step explanation:

The right Riemann Sum uses the right endpoints of a sub-interval:

$\int_{a}^{b}f(x)dx\approx\Delta{x}\left(f(x_1)+f(x_2)+f(x_3)+...+f(x_{n-1})+f(x_{n})\right)$

where

$\Delta{x}=\frac{b-a}{n}$

To find the Riemann sum for $\int\limits^{4}_{-6} {3x-1} \, dx$ with n = 5 rectangles, using right endpoints you must:

We know that a = -6, b = 4 and n = 5, so

$\Delta{x}=\frac{4-\left(-6\right)}{5}=2$

We need to divide the interval −6 ≤ x ≤ 4 into n = 5 sub-intervals of length $\Delta{x}=2$

$a=\left[-6, -4\right], \left[-4, -2\right], \left[-2, 0\right], \left[0, 2\right], \left[2, 4\right]=b$

Now, we just evaluate the function at the right endpoints:

$f\left(x_{1}\right)=f\left(-4\right)=-13=-13$

$f\left(x_{2}\right)=f\left(-2\right)=-7=-7$

$f\left(x_{3}\right)=f\left(0\right)=-1=-1$

$f\left(x_{4}\right)=f\left(2\right)=5=5$

$f\left(x_{5}\right)=f(b)=f\left(4\right)=11=11$

Finally, just sum up the above values and multiply by 2

$2(-13-7-1+5+11)=-10$

The Riemann sum equals -10
