Answer:

B. −24

Step-by-step explanation:

The coefficients of a polynomial are the numerical factor of each term .

The next polynomial: −24*x^7*y^3 only have one term and its numerical factor, that is, its coefficient is -24. Notice that minus sign is included

Answer:

Area: $\frac{8}{15}$ feet²

Perimeter: $\frac{44}{15} =2 \frac{14}{15}$ feet

Step-by-step explanation:

The formula of finding the area of a rectangle or square is width multiplied by length.

The formula of find the perimeter of a rectangle or square is width+width+length+length

Area: $\frac{4}{5} *\frac{2}{3} = \frac{8}{15}$ feet²

Perimeter:

$\frac{4}{5} +\frac{4}{5} +\frac{2}{3} +\frac{2}{3} =$

$\\\\\frac{12}{15} +\frac{12}{15} +\frac{10}{15} +\frac{10}{15} =\\\\\frac{24}{15} +\frac{20}{15} =\\$

$\frac{44}{15} =2 \frac{14}{15}$

If triangle ksd~wat, what is the measure of w? Let K=16, D=34 and T=51

valentinak56 [21]

You have mentioned that two of the angles of ΔKSD are ∠K=16° and ∠D=34°. So that would mean that ∠S=130°, because∠K+∠D+∠S=180°. That's because all the angles of any triangle must total 180°. But you also say that ∠T=51°. But since no angle of ΔKSD can equal 51°, neither can any angle of ΔWAT equal to 51°. Therefore ∠T=51° is impossible!

Answer:

7. ∠CBD = 100°

8. ∠CBD = ∠BCE = 100°; ∠CED = ∠BDE = 80°

Step-by-step explanation:

7. We presume the angles at A are congruent, so that each is 180°/9 = 20°.

Then the congruent base angles of isosceles triangle ABC will be ...

∠B = ∠C = (180° -20°)/2 = 80°

The angle of interest, ∠CBD is the supplement of ∠ABC, so is ...

∠CBD = 180° -80°

∠CBD = 100°

8. In the isosceles trapezoid, base angles are congruent, and angles on the same end are supplementary:

∠CBD = ∠BCE = 100°

∠CED = ∠BDE = 80°

Answer:

One cup of coffee is $3.25

Step-by-step explanation:

Create a system of equations where c is the cost of a cup of coffee and d is the cost of a donut

2c + 4d = 10.5

c + 5d = 8.25

Solve by elimination by multiplying the top equation by -5 and the bottom equation by 4

-10c - 20d = -52.5

4c + 20d = 33

Add them together and solve for c

-6c = -19.5

c = 3.25

So, a cup of coffee is $3.25

Christopher borrowed $22,000 for 7 years. At the end of the loan, he had paid a total of $27,390. Find the interest rate on the

oee [108]

Step-by-step explanation:

okay so we know i = prt

in this scenario

p = 22,000

r = ?

t = 7

i = 27,390

the equation for r is (i/p*t)

so now let's plug in what we know

r = 27,390/22,000 * 7

r = 1.245 / 7

r = 8.715
