Answer:

z ≥ -10

Step-by-step explanation:

When the circle is filled it means the direction its going (less than or greater than) or equal to in this case the line is going farther than -10 so its greater than or equal to -10. Z would be your variable so its z ≥ -10

What is the measure of angle A in the triangle?<br> Enter your answer in the box.<br> mZA=

stepladder [879]

Answer:

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

A + B + C = 180

2x-10 + 70+ x+30 = 180

Combine like terms

3x +90 = 180

Subtract 90 from each side

3x+90-90=180-90

3x= 90

Divide by 3

3x/3= 90/3

x=30

We want to find angle A

A = 2x-10

=2*30 -10

=60-10

By selling a cow for Rs 144, there is a profit of the same percentage as its cost price. Find the cost price.

hjlf

Answer:

Step-by-step explanation:

<h2><u>☼︎</u><u>Answer:</u></h2>

The cost price of cow = Rs.80

Explanation:

<h2><u>☼︎</u><u>Given :-</u></h2>

By selling a cow for Rs 144, there is a profit of the same percentage as its cost price.

The cost price.

The cost price of cow = Rs.x

<h2><u>☼︎</u><u>Solution :-</u></h2>

$\sf x + x \: of \: x\%= 144 \\ \\ \sf \implies x + \frac{x \times x}{100} = 144 \\ \\ \sf \implies {x}^{2} + 100x - 14400 = 0 \\ \\ \sf \implies x(x - 80) + 180(x - 80) = 0 \\ \\ \sf \implies x + 180 = 0 \\ \\ \sf \implies x = - 180 \\ \\ \sf \therefore \: {\boxed{ \sf \pink{x = 80}}}$

<h2><u>Hence: </u></h2>

The cost price of cow =<u>R</u><u>s</u><u>8</u><u>0</u>

Find the 77th term of the arithmetic sequence 8, 26, 44, ...

Sindrei [870]

Answer: 1,376

Step-by-step explanation: All we need to do is take our explicit formula and plug in the information we need to know for the problem.

Explicit formula - $a_{n} = a_{1} + (n - 1) d$

We are trying to find the 77th term of this sequence so we first have $a_{77}$ .

We know $a_{1}$ is 8 because that's the first term in our arithmetic sequence.

The variable <em>n</em> represents the number of terms we're trying to solve for which is 77. So that will be 77 - 1 and then we are going to multiply that by our common difference which is 18.

So plugging into the formula, we have $a_{77} = 8 + (77 - 1)18$

So now we can go ahead and simplify this

information and see what we get.

So simplifying inside parentheses first, we get 76 and we multiply that by 18 to get 1,368.

So therefore we have $a_{77} = 8 + 1,368$ which is 1,376.
