Answer:

14b - 10ab + 34a²b - 64a²b²

Step-by-step explanation:

We have to simplify the expression

2ab + 3b + 7b + 3a × 3a × b + 4b - 8ab × 8ab + 5a × 5a × b - 12ab

= 2ab + 3b + 7b + 9a²b + 4b - 64a²b² + 25a²b - 12ab

{Since (3a × 3a × b) = 9a²b, (8ab × 8ab) = 64a²b² and (5a × 5a × b) = 25a²b}

= 2ab + 10b + 9a²b + 4b - 64a²b² + 25a²b - 12ab  

= 14b - 10ab + 34a²b - 64a²b² (Answer)

The diagram shows a circle with center C, a diameter RS, and an inscribed triangle RST.
snow_tiger [21]

Answer:

x = 26

Step-by-step explanation:

m<RTS = 4x - 14 (given)

Based on the inscribed angle theorem, the measure of the inscribed angle in a semicircle = right angle (90°)

Therefore,

4x - 14 = 90

4x - 14 + 14 = 90 + 14 (addition property of equality)

4x = 104

4x/4 = 104/4

x = 26

Answer:

1

Step-by-step explanation:

By  gradient, if you mean the "slope" of the linear function, then you have to find two points of the graph and use the "rise over run strategy". Given two coordinates, (x1, y1) and (x2, y2) of a linear function in the form y=mx+b, the slope of the line is (y2-y1)/(x2-x1). This shows the amount of "rise", or the vertical change, and the amount of "run", which is the horizontal change. Rise/Run gives the steepness of the line. The slope can also be modeled by Δy/Δx, which is the change in y over the change in x

Plugging in the given points (0,5) and (-5,0):

(y2-y1)/(x2-x1)= (5-0)/(0-(-5)) = 5/5 = 1

Tom ordered a jacket at $70, a shirt at $30, and slacks at $38. If sales tax is 6% and the shipping and handling is $10.75, what
vodomira [7]
For question 1, We need to calculate the total, find the tax, then add the shipping cost to the total. (70+30+38=138) now we find the tax (138*0.06=8.28) Now we add the tax and cost together and then the shipping and handling and we have our answer (138+8.28+10.75=157.03) So your answer is A.

For question 2, We need to calculate the total and then find the tax. So, we do this: 25.67*3=77.01. Then we add the skirt to the total (77.01+23.55=100.56). Finally, we calculate the tax cost (100.56*0.08=8.0448). So our total is (100.56+8.0448=108.6048) So the answer is A.

The company has a sample box that is a rectangular prism with a rectangular base with an area of 231⁄3 in2. The height of the pr
vodka [1.7K]

Answer:

29.17 in^3

Step-by-step explanation:

We are given that  

Base area of sample box,a=23\frac{1}{3} in^2=\frac{70}{3}in^2

Height of the sample box,h=1\frac{1}{4}=\frac{5}{4} in

We have to find the volume of the sample box.

We know that  

Volume of rectangular prism,V=ah

Where a=Area of base

Using the formula  

Volume of sample box=\frac{70}{3}\times \frac{5}{4}=29.17 in^3

Hence, the volume of the sample box=29.17 in^3
