Answer:
mB=46
Step-by-step explanation:
2x+30+7x-3=90
Combine like terms
9x+27=90
Subtract by 27 on both sides
9x=63
Divide by 9 on both sides
x=7
mB=(7x-3)
Substitute 7 for x
mB= 7(7)-3
mB= 49-3
mB=46
Answer:
The measure of B is 46°
Step-by-step explanation:
To solve this equation, you need to add the two equations, and set them equal to 90° since they are complementary angles
2x+30+7x-3=90
You also need to add like terms, so 2x+7x and 30+-3, or 30-3
9x+27=90
Then you need to isolate the variable by subtracting 27 from both sides
9x+27-27=90-27
=
9x=63
Then you need to divide both sides by 9 to get x=7
Since we know what x is, we plug x into the equation (7x-3) and we will now have 7(7)-3.
To solve this, we multiply 7 and 7, and subtract 3 to get 46.
So the answer is mB=46

What’s the y intercept
Answer:
y-intercpet is In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.

As you can see, he uses one square for Stage 1, three squares for Stage 2 and six for Stage 3.
How many squares should he use for the sixth stage?
Answer:
21 squares
Step-by-step explanation:
1 = 1
2 = 3
3 = 6
The pattern follows squares use in the previous stage + new stage = squares use the new stage
Squares used in stage 2 = Squares used in stage 1 + stage 2
= 1 + 2
= 3 squares
Squares used in stage 3 = Squares used in stage 2 + stage 3
= 3 + 3
= 6 squares
Squares used in stage 4 = Squares used in stage 3 + stage 4
= 6 + 4
= 10 squares
Squares used in stage 5 = Squares used in stage 4 + stage 5
= 10 + 5
= 15 squares
Squares used in stage 6 = Squares used in stage 5 + stage 6
= 15 + 6
= 21 squares
4 = 10
5 = 15
6 = 21

The equation of a circle is (x−2)2+(y+6)2=100. Find the equation of a circle that is externally tangent to the given circle and has a center at (14, 3).
Answer:
(x-14)^2+(y-3)^2=9
Step-by-step explanation:
equation of a circle is (x-h)^2+(y-h)^2=r^2
so center is (14,3) and is tangent externally means
(x-14)^2+(y-3)2=3^2
(x-14)^2+(y-3)^2=9 answer
The equation of a circle is externally tangent to the given circle and has a center at (14, 3) is [tex](x-14)^2 + (y-3)^2=9[/tex]
The standard formula for finding the equation of a circle is expressed as:
[tex](x-a)^2+(y-b)^2=r^2[/tex]
where
(a, b) is the centre
r is the radius
Given the center at (14, 3)
If the equation of a circle is externally tangent to the given circle and has a center at (14, 3), then the radius will be 3
Substitute the radius and the centre into the expression above to have:
[tex](x-14)^2 + (y-3)^2=3^2\\(x-14)^2 + (y-3)^2=9[/tex]
Hence the equation of a circle is externally tangent to the given circle and has a center at (14, 3) is [tex](x-14)^2 + (y-3)^2=9[/tex]

Let us take ,
First integer be x .Second integer be y .Also let us consider x > y .
According to first Condition :-
⇒ x - y = 1.
⇒ x = y + 1. .............(i)
According to second Condition :-
⇒ x × y = 30 .
⇒ ( y + 1 )y = 30 . [ From (i) ]
⇒ y² + y = 30.
⇒ y² + y - 30 = 0 .
⇒ y² + 6y - 5y -30 = 0.
⇒ y ( y + 6 ) -5 ( y + 6 ) = 0 .
⇒ ( y + 6 ) ( y - 5 ) = 0 .

(Type integers or fractions as the answer.) like top to down
Answer:
$22
Step-by-step explanation:
Hi here is the explanation
We just do the opposite of the question
We just add the values
So 3+8=11
Now multiply. Since when we have the total and we spent haslf of it, we divide, so now we multiply by reciprocal, the opposite
11*2=22 (2 is the reciprocal)
Now let’s see we did it right
22*1/2=11
Now let’s subtract to find the remaining
11-3=8
As you can see, we are right as they had $8 left.
