What is (1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x), simplified?

(1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x)

1.6x + 7.3 – 0.6x + 2 – 7.8 + 3.4x

1.6x – 0.6x + 3.4x + 7.3 + 2 – 7.8

Answer:

B

Step-by-step explanation:

A GCF would mean you can divide both terms by that number. For A it would be ac, C would have c, and D would be b, so the only one which cannot be divided by anything except 1 is B.

answer: 105

Step-by-step explanation:

For triangle area you just have to do base × height ÷ 2 So we will do 8 × 5 = 40 then divide by 40 by 2 so 40 ÷ 2 = 20 now we have 1 triangles area we can find the rest because each of these triangles are equal so 20 × 4 = 80 now we just have to do the square so thats easily just base × height so 5 × 5 = 25 now we just add 80 and 25 so 80 + 25 = 105 so 105 is our surface area!

Step-by-step explanation:

Solve for one variable and substitute the value in to another equation.

Answer:

LSA = 2πrH

Step-by-step explanation:

The lateral surface area of a cylinder is given by the formula as:

LSA = 2πrH

where, r and H are radius and height of the cylinder respectively.

The volume of cylinder is πr^2H

and Total surface are of cylinder = LSA+ 2× base are

= 2πrH +2πr^2

You can substitute any values of r and H to find LSA of the cylinder

Given:

The expression is:

[tex]a\times a\times a\times c\times c\times c\times c\times 5\times 5\times 5\times 5[/tex]

To find:

The index form of a the given expression.

Solution:

Index form is the exponent form.

We have,

[tex]a\times a\times a\times c\times c\times c\times c\times 5\times 5\times 5\times 5[/tex]

Here, a is multiplied with itself 3 times, c is multiplied with itself 4 times and 5 is with itself 4 times. So, the power of a, c and 5 must be 3, 4 and 4 respectively.

[tex]a\times a\times a\times c\times c\times c\times c\times 5\times 5\times 5\times 5=a^3c^45^4[/tex]

Therefore, the index form of the given expression is [tex]a^3c^45^4[/tex].

Step-by-step explanation:

The market price and profit amount if the shopkeeper paid 2500 for the article​ will be 3250 and 11.05%.

Profit is made when the money generated from a commercial operation exceeds the expenses, charges, and taxes associated with operating the activity in question.

Given data;

Purchase price = 2500

Given condition;

The markup is 30% more than the purchasing price.

Mark Price is found as;

[tex]\rm MP = \frac{130}{100}\times 2500 \\\\ MP =130\times 25\\\\ MP=3250[/tex]

The marked price of an article will be 3250.

Since we are aware that discounts usually apply to mark prices, a 15 percent discount is now being offered;

[tex]\rm \frac{85}{100}\times 3250 = 2762.5 RS[/tex]

The profit in the article is found as;

Profit = 2762.5-2500

Profit = 226.25 RS

Now profit % is found as;

[tex]\% profit = \frac{276.25}{2500}\times 100 \\\\ \% profit = 11.05 \%[/tex];

Hence, the market price and profit amount, if the shopkeeper paid 2500 for the article,​ will be 3250 and 11.05%.

Answer:

Blank 1; AB

Blank 2; AC

Blank 3; BC

Step-by-step explanation:

Mathematically, the greater the angle that faces a side of a triangle, the bigger the side length of the triangle

so what this mean is that, bigger side lengths faces bigger angles

From the list of angles we have, the side that faces vertex C is the biggest

We have this as;

AB faces C and that is the biggest

the next is the side that faces angle B; we have the length as AC

the least faces angle A ; we have the length as BC

Answer:

See below directions.

Step-by-step explanation:

The condition [tex]-2\pi<\theta<2\pi[/tex] means you can get to the point by rotating no more than one revolution in either the positive or negative direction.

See the attached image to see the point [tex]\left(3,\,-\frac{3\pi}{4}\right)[/tex].  Think about how you get to that point:  start at the origin, go right (along the positive x-axis) 3 units, then turn in the negative direction (to your right!) through an angle of [tex]\frac{3\pi}{4}[/tex].

Now, go again, starting at the origin, only this time, go 3 units right, then turn through an angle of [tex]-\frac{3\pi}{4}+2\pi=\frac{5\pi}{4}[/tex].  In other words, you turn one whole revolution in addition to the [tex]-\frac{3\pi}{4}[/tex] angle.  Your point can now be described by [tex]\left(3,\,\frac{5\pi}{4}\right)[/tex].

Another description can be found by rotating in the opposite direction, so an angle of [tex]\frac{3\pi}{4}[/tex] and backing up 3 units -- specify a "radius" of -3.  The point is then [tex]\left(-3,\,\frac{3\pi}{4}\right)[/tex].

You can also try subtracting one revolution [tex](2\pi)[/tex] from the angle, but be careful not to let the angle go outside the interval  [tex]-2\pi<\theta<2\pi[/tex].

The changes you can try are:  

add [tex]2\pi[/tex] to the angle, leave r alone

subtract [tex]2\pi[/tex] to the angle, leave r alone

add/subtract [tex]\pi[/tex] (half a revolution) to the angle, make r the opposite.

Answer:

39.6 cm

Step-by-step explanation:

Applying

s = 2πrθ/360................ Equation 1

Where s = length of an arc or distance traveled by the minutes hand of the clock during the 42 munites, r = length of the minutes hand of the clock, θ = Angle traveled by the minute hand of the clock for every 42 minutes

From the question,

Given: r = 9 cm, θ = 252°

Constant: π = 22/7 = 3.14

Substitute these values into equation 1

s = (2×3.14×9×252)/360

s = 39.564

s = 39.6 cm

Just a pure guess. I got roasted a lot of times :( so I just guessed

126 groups can be made.

Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements. The number of combinations of n different things taken r at a time, denoted by

n^C_r = n!/ r!( n-r)!

Suppose we have a set of 6 letters { A,B,C,D,E,F}. In how many ways can we select a group of 3 letters from this set? Suppose we find the number of arrangements of 3 letters possible from those 6 letters. That number would be 6P3

. Consider the permutations that contain the letters A, B, and C. These are 3! = 6 ways, namely ABC, ACB, BAC, BCA, CAB, and CBA.

We calculate combinations using the combinations formula, and by using factorials and in terms of permutations. In general, suppose we have n things available to us, and we want to find the number of ways in which we can select r things out of these n things. We first find the number of all the permutations of these n things taken r at a time. That number would be

nPr.

Given:

n= 9, r=5

n^C_r= 9!/ 5! * 4!

= 9*8*7*6/ 4*3*2

=126

Hence, there are 126 ways.
