Answer: 2.79 x 10 to the 5th power
Step-by-step explanation: Your welcome :)
Answer:
2.79 x [tex]10^{5} }[/tex]
Step-by-step explanation:
7.9 x [tex]10^{4}[/tex] = 79000
2 x [tex]10^{5}[/tex] = 200000
79000 + 200000 = 279000
279000 = 2.79 x [tex]10^{5} }[/tex]
Hope this helps, I'm sorry about the earlier question but I fixed it:)

How do you find the angle measure?
Answers
Answer:
∠ XYZ = 41°
Step-by-step explanation:
∠ XYZ = ∠ 3x + 20 ( corresponding angles ) , thus
8x - 15 = 3x + 20 ( subtract 3x from both sides )
5x - 15 = 20 ( add 15 to both sides )
5x = 35 ( divide both sides by 5 )
x = 7
Thus
∠ XYZ = 8x - 15 = 8(7) - 15 = 56 - 15 = 41°

Express the statement "A rectangular field with an area of 120m' has it length 12mn longer than the width" as quadratic equation.
Answers
Answer:
The quadratic equation is x^2 -12x -120 = 0
where x represents the length of the field
Step-by-step explanation:
We want to make an expression in terms of a quadratic equation;
Let the length of the field be x mm , then the width will be (x-12) mm
Mathematically , the area of the field will be L * B
Thus;
x * (x-12) = 120
That gives;
x^2 -12x = 120
x^2 -12x -120 = 0

Answers
Solve the system by substitution.
-9x-10y=12
−3x+3=y
X=2
Y= -3
Answer:
[tex]x=2\\y=-3[/tex]
Step-by-step explanation:
We have:
[tex]-9x-10y=12\\-3x+3=y[/tex]
Since we already have a variable value ([tex]y[/tex]) in the second equation, it would be easiest to substitute the value for [tex]y[/tex] in the first equation:
[tex]-9x-10(-3x+3)=12[/tex]
Distribute [tex]-10[/tex] into [tex](-3x+3)[/tex]:
[tex]-9x+30x-30=12[/tex]
Combine like terms:
[tex]21x-30=12[/tex]
Add [tex]30[/tex] to both sides of the equation:
[tex]21x=42[/tex]
Divide by the coefficient of [tex]x[/tex], which is [tex]21[/tex]:
[tex]x=2[/tex]
_
Now that we have our [tex]x[/tex] value, we can substitute that in to the second equation to find our [tex]y[/tex] value:
[tex]-3(2)+3=y[/tex]
Multiply:
[tex]-6+3=y[/tex]
Combine like terms:
[tex]-3=y[/tex]

Write the equation of a line that is perpendicular to 2x-7y=13 and which passes through the point ( -3,8).
Answers
Given parameters:
Equation of the line given 2x - 7y = 13
Coordinates of points = -3, 8
Unknown:
Equation of a line perpendicular = ?
Solution;
To find the equation of this line, simply find the negative inverse of the given line.
m = [tex]-\frac{1}{m}[/tex]
2x - 7y = 13 , this is an equation of a straight line
let us write it in the form y = mx + c so as to derive the slope
y and x are coordinates
m is the slope
c is the y intercept
2x - 7y = 13;
-7y = -2x + 13
divide through by -7;
y = [tex]\frac{2}{7}x[/tex] + [tex]\frac{13}{7}[/tex]
The slope of this line is [tex]\frac{2}{7}[/tex];
Now the slope of a line perpendicular to it will be [tex]-\frac{7}{2}[/tex];
the equation of the line will be;
y = [tex]-\frac{7}{2} x + C[/tex]
Since the coordinate of this line is (-3,8) , let us find C;
y = 8 and x = -3;
8 = [tex]-\frac{7}{2}[/tex] (-3) + C
multiply through by 2;
16 = 21 + 2C
16 - 21 = 2C
-5 = 2C
C = [tex]\frac{-5}{2}[/tex]
Now the equation of the line is;
y = [tex]-\frac{7}{2} x + \frac{5}{2}[/tex]

[tex] {30}^{2} \div {100}^{2} + {3}^{2} [/tex]
Answers
Answer:
3mStep-by-step explanation:
The length of the ramp will be the longest side of the right-triangular shape (the hypotenuse). The height and the horizontal length will be the other two sides (adjacent and opposite).
Acording to the theorem;
hyp² = opp²+adj²
Given
opp = 30cm = 0.3m (convert to metres)
adj = 3 m
Substitute
hyp² = 0.3²+3²
hyp² = 0.09+9
hyp² = 9.09
hyp = √9.09
hyp = 3.0145 m
Hence the estimated length of the ramp in meters is 3m
