Answer:
The value of x is 25.
Step-by-step explanation:
Answer:
112+3x^2-7 = 180
105+3x^2 = 180
3x^2 = 180-105
3x^2 = 75
x^2 = 25
x = [tex]\sqrt{25}[/tex]
x = 5

Answer:
1888 × [tex]10^{8}[/tex]
or
188.8 × [tex]10^{9}[/tex]
or
18.88 × [tex]10^{10}[/tex]
Step-by-step explanation:
Lets look at this in a more simple way:
[tex](5.9[/tex] × [tex]10^{6} )[/tex] × [tex](3.2[/tex] × [tex]10^{4} )[/tex]
First, let's move [tex]10^{6}[/tex] and switch it's places with 3.2:
(5.9 × 3.2) × ([tex]10^{6}[/tex] × [tex]10^{4}[/tex])
Then, let's simplify:
18.88 × [tex]10^{10}[/tex]

*Two buses were coming from two different places situated just in the opposite
direction. The average speed of one bus is 5 km/hr more than that of another on
and they had started their journey in the same time. If the distance between
places is 500 km and they meet after 4 hours, find their speed.
Answer: 60 km/hr and 65 km/hr
Step-by-step explanation:
o-----------------------------------←500→-------------------------------------o
Bus 1: rate = r + 5 Bus 2: rate = r
time = 4 time = 4
distance = d distance = 500 - d
Use distance = rate x time
Bus 1: d = 4(r + 5) Bus 2: 500 - d = 4(r)
d = 4r + 20 -d = 4r - 500
d = 500 - 4r
Solve the System of Equations using the Substitution method:
4r + 20 = 500 - 4r
8r + 20 = 500
8r = 480
r = 60
Bus 1: rate = r + 5 Bus 2: rate = r
= 60 + 5 = 60
= 65
Distance between both buses = 500km
Time taken by them to meet each other = 4hr
Let speed of bus A be v km/hr.
ATQ, speed of bus B is 5km/ hr more than that of bus A.
∴ Speed of bus B will be (v + 5) km/hr.

★ As we know that,
Speed = Distance/Time ... (I)Assuming both buses as point masses,
Relative speed of object A wrt object B when the object B moves in the opposite direction of A is given by
[tex]\boxed{\bf{v_{AB}=v_A+v_B}}[/tex]Relative speed of bus A wrt B :
[tex]:\implies\:\sf{v_{AB}=v_A+v_B}[/tex]
[tex]:\implies\sf\:v_{AB}=v+(v+5)[/tex]

The gravity on the surface of the moon is 0.17 of the surface gravity on Earth. If Jack weighs 156 pounds on Earth, what would be his weight on the moon? (Will give brainliest)
Answer:
Jack will weigh 26.52 pounds
Step-by-step explanation:
x = 156 (Your weight on Earth)
y = 0.17 (Surface Gravity)
z = Your weight on the moon
x * y = z
156 * 0.17 = 26.52
Jack will weigh 26.52 pounds.
If Jack weighs 156 pounds on Earth his weight on the moon will be 26.52 pounds.
What is gravitational force?All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.
It is given that,
Gravity on the surface of the moon = 0.17
Weighs of Jack on Earth = 156 pounds
Mass of Jack,
W=mg
156 pounds = m × 9.81 [ g on earth = 9.81 m/s²]
m = 15.902 kg
The weight of Jack on the moon is,
W= 15.902 kg × 0.17
W=2.565 N
Thus, if Jack weighs 156 pounds on Earth his weight on the moon will be 26.52 pounds.

Not sure what does "Zero" mean. But I'll move with y-intercept, slope and slope intercept form.
The y-intercept is (0,4) because the graph passes through (0,4)
For the slope, look at the grid and the line, it's -2. Or we can solve this by using the ordered pairs.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
(0,4) and (3,-2) both are the part of the graph, therefore.
[tex]m=\frac{-2-4}{3-0} \\m=-\frac{6}{3}\\m=-2[/tex]
So the slope is -2 and for the slope intercept form, it must be the equation.
We know that m = -2 and b = 4 because b is the y-intercept from y = mx+b where m is the slope and b is the y-intercept.
Thus, [tex]y=-2x+4[/tex] from the y = mx + b.
Sara owns a tree farm. Variety A of a pine tree is shipped to her at 12 inches tall and grows at a rate of 14 inches per year. Variety B of a pine tree is shipped to her at 2 inches tall and grows at a rate of 16 inches per year.
Which equation can be used to determine the number of years, x, at which the trees will be an equal height?
14 + 12x = 16 + 2x
14 + 12, x, = 16 + 2, x
16 + 12x = 14 + 2x
16 + 12, x, = 14 + 2, x
12 + 16x = 2 + 14x
12 + 16, x, = 2 + 14, x
12 + 14x = 2 + 16x
12 + 14, x, = 2 + 16, x

What’s -6y + 4x=5 in ymx+b
Answer:
[tex]\boxed {y = \frac{2}{3}x - \frac{5}{6}}[/tex]
Step-by-step explanation:
First you need to solve the expression in order to get the expression in Slop-Intercept Form:
[tex]y = mx + b[/tex]
-The following equation:
[tex]-6y + 4x = 5[/tex]
Solve:
[tex]-6y + 4x = 5[/tex]
[tex]-6y + 4x - 4x = 5 - 4x[/tex]
[tex]-6y = 5 - 4x[/tex]
[tex]\frac{-6y}{-6} = \frac{5 - 4x}{-6}[/tex]
[tex]y = \frac{5 - 4x}{-6}[/tex]
[tex]\boxed {y = \frac{2}{3}x - \frac{5}{6}}[/tex]
Therefore, the expression in Slope-Intercept Form is [tex]y = \frac{2}{3}x - \frac{5}{6}[/tex].

Amber worked 2.2 hours on Monday and 5.9 hours on Tuesday. Her pay rate is $9.50 per hour. How much will Amber be paid for two days?
Answer:
$76.95
Step-by-step explanation:
Amber worked for 2.2 hours on Monday and she makes $9.50 per hour, so that means you multiply 9.50 x 2.2 and it equals 20.9, then it says she works 5.9 hours on Tuesday, so that means you multiply 9.50 x 5.9 and it equals 56.05, so in total you add 20.9 from Monday and 56.05 from Tuesday and it equals 76.95, which means $76.95 is how much Amber will be paid.
Answer:
76.95

A quadratic function for a parabola has axis of symmetry x = -2, points (-3, 2) and (0,11) and opens upward. What is the value of a? What is the vertex?
Answer:
Let's see what to do buddy..
Step-by-step explanation:
_________________________________
STEP (1)
We know that the quadratic functions form are like this :
[tex]y = a \: {x}^{2} + b \: x + c [/tex]
The quadratic function opens upward so ;
[tex]a > 0[/tex]
The axis of parabolic symmetry passes through the vertex of the parabolic.
So we know that x vertex is equal to -2.
The vertex's x is finding from this equation:
[tex]x = - \frac{b}{2a} \\ [/tex]
So we have :
[tex] - 2 = - \frac{b}{2a} \\ [/tex]
Multiply the sides of the equation by 2a :
[tex]b = 4a[/tex]
_________________________________
STEP (2)
A quota passes through points (-3,2) and (0,11) , so points (-3,2) and (0,11) must be true in the quota equation.
[tex]y = f(x) = a{x}^{2} + bx + c \\ \\b = 4a \\ \\ y = f(x) = a {x}^{2} + 4ax + c [/tex]
[tex]f( - 3) = 2 \\ \\ a ({ - 3})^{2} + 4a( - 3) + c = 2 \\ \\ 9a - 12a + c = 2 \\ \\ - 3a + c = 2 \\ \\ \\ \\ f(0) = 11 \\ \\ a ({0})^{2} + 4a(0) + c = 11 \\ \\ c = 11 [/tex]
[tex] - 3a + c = 2 \\ \\ c = 11 \\ \\ - 3a + 11 = 2 \\ 11 \: goes \: to \: the \: other \: side \: \\ \\ - 3a = 2 - 11 \\ - 3a = - 9 \\ divided \: the \: sides \: of \: the \: equation \: by \: - 3 \\ a = 3[/tex]
And we're done.
Thanks for watching buddy good luck.
