Answer:
a = -40/3
Step-by-step explanation:
(7a - 4) = (4a - 44)
7a - 4 = 4a - 44
7a = 4a - 44 + 4
7a = 4a - 40
7a - 4a = - 40
3a = - 40
3a/3 = -40/3
a = -40/3 or -13.3333 repeating

A 40 kg-skier is standing at the top of a 12-meter high slope. What is her potential energy? PE = m x g x h (g = 10m/s2) A. 6000J B. 48J C. 4800J D. 400J
Answer:
The correct option is;
C. 4800 J
Step-by-step explanation:
The given parameters are;
The mass of the skier = 40 kg
The height of the slope = 12 meter
The acceleration due to gravity, g = 10 m/s²
The potential energy, PE, is given by the formula PE = Mass, m × Acceleration due to gravity, g × Height, h
Substituting the values, gives
The potential energy, PE = 40 kg × 10 m/s² × 12 m = 4800 kg·m²/s² = 4800 J
The potential energy, PE = 4800 J

find the greatest number by which 90,120 and 150 are exactly divisible
Answer:
30
Step-by-step explanation:
Prime factors of 90 = 2 x 3^2 x 5
Prime factors of 120 = 2^3 x 3 x 5
Prime factors of 150 = 2 x 3 x 5^2
Common prime factors with lowest exponent: 2, 3, 5
HCF(highest common factor) = 2 x 3 x 5 = 30
Answer:
30
Step-by-step explanation:
30 is divisible by 90, 120 and 150

Answer: B
Step-by-step explanation:
Assume that y varies directly with x. If y=9 when x=−3, find x when y=6. Enter in any fractions using a / (e.g. "1/2" is the same as 1^/2).
Answer: 2
Step-by-step explanation:
This is a direct proportion. Since y varies as x. This will be:
y = kx
where,
y = 9
x= 3
9 = 3k
k = 9/3
k = 3
Find x when y=6
y = kx
6 = 3x
x = 6/3
x = 2

Using the model, approximate the number of ice cream cones sold when it is 85°F. Round your answer to the nearest whole number.
Answer:
76.1
Step-by-step explanation:
y = ice cream
z = Tempreature
y = 1.8(85) - 76.9
1.8(85) = 153
153 - 76.9 = 76.1
Answer:
76
Step-by-step explanation:
y = 1.8(85) - 76.9
y = 153 - 76.9
y = 76.1
and when you round to the nearest whole number,
y = 76

LCM(84,90) = 1260
Answer:
HCF = 2 * 3
LCM = 2 *2 * 3 * 3 * 5 * 7
Step-by-step explanation:
A) 84 = 2 * 2 * 3 * 7
90 = 2 * 3 * 3 * 5
HCF = 2 * 3
B) 84 = 2 * 2 * 3 *7
90 = 2 * 3 * 3 * 5
LCM = 2 *2 * 3 * 3 * 5 * 7

A rectangle has a width of 9 units and a length of 40 units. What is the length of a diagonal? 31 units 39 units 41 units 49 units
Answer: 41 units
Step-by-step explanation: took the quiz
The length of the diagonal is 41 units.
To find the length of a diagonal.
What is rectangle?A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees.
Let a right triangle with legs length 9 units and 40 units and hypotenuse is the diagonal length c.
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]9^{2} +40^{2} =c^{2}[/tex]
[tex]81+1600=c^2\\1681=c^2[/tex]
sqrt both sides
41=c
So, the length of the diagonal is 41 units.

The graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2 what is the zero of f ?
Answer:
Check the explanation.
Step-by-step explanation:
As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.
As the slop-intercept form is given by:
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept.
substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.
[tex]y = mx+b[/tex]
[tex]-10=\frac{5}{2}\left(-2\right)+b[/tex]
[tex]-\frac{5}{2}\cdot \:2+b=-10[/tex]
[tex]-5+b=-10[/tex]
[tex]-5+b+5=-10+5[/tex]
[tex]b=-5[/tex]
And the equation of the line in the slope-intercept form will be:
[tex]y = mx+b[/tex]
putting b = -5 and slope = m = 5/2
[tex]y = mx+b[/tex]
[tex]y=\frac{5}{2}x+\left(-5\right)[/tex]
[tex]y=\frac{5}{2}x-5[/tex]
Determining the zero of function.
As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.
so let us determine the value of x (zero of function) by setting y = 0.
[tex]0=\frac{5}{2}x-5[/tex]
[tex]\frac{5}{2}x-5=0[/tex]
[tex]\frac{5}{2}x=5[/tex]
[tex]5x=10[/tex]
[tex]x=2[/tex]
Therefore, the zeros of the function will be:
x = 2Given that point P is equidistant from the vertices of ΔDEF, what is EF? EF =

The tens digit of a two digit number is five more than the units digit. Seven times the sum of the digits of this number is 3 less than the number itself. Find the number.
Answer:
94
Step-by-step explanation:
Let the unit's digit = [tex]y[/tex]
Let the ten's digit = [tex]x[/tex]
Then the number will be equal to [tex]10x+y[/tex]
Now, using the given statement:
[tex]x=y+5 ..... (1)[/tex]
[tex]7(x+y) = 10x+y-3\\\Rightarrow 7x+7y=10x+y-3\\\Rightarrow 6y-3x=-3 ..... (2)[/tex]
Now, using the equation (1) in equation (2):
[tex]6y-3(y+5) =-3\\\Rightarrow 3y-12=0\\\Rightarrow y =4[/tex]
By equation (1):
[tex]x = 4+5 \\\Rightarrow x =9[/tex]
Therefore, the number is :
[tex]10x+y= 10\times 9 +4 = \bold{94}[/tex]
