Answer:
10m
Step-by-step explanation:
we can use the cross multiply method.
300m = 270m
x m = 90m
270x = 300 x 90
270x = 2700
x = 10
so the buliding is 10m tall

Which system models this situation? h = 3t 10 and h = -16t2 15t 6 10t 3 and h = -16t2 6t 15 -16t2 3t 10 and h =-16t2 15t 6 -16t2 10t 3 and h = -16t2 6t 15.
The system of equations that model this situation are [tex]h = -16t^{2}+15t +6[/tex] and [tex]h = 3t +10[/tex].
As we know,
Projectile motion formula,
[tex]h = -16t^{2}+vt +h_{0}[/tex].....(1)
Where, t = time since the measuring tape was thrown.
h = height in feet above the ground.
What is a projectile motion?Projectile motion is a form of motion experienced by an object or particle that is projected near the Earth's surface and moves along a curved path under the action of gravity only.
It is given that:
v =15 feet/sec
h₀ = 6 feet
So, (1) will become,
[tex]h = -16t^{2}+15t +6[/tex]
Also, h = distance of worker's arm from the ground + speed of bucket * time(t)
[tex]h = 3t +10[/tex]
Therefore, the system of equations that model this situation are [tex]h = -16t^{2}+15t +6[/tex] and [tex]h = 3t +10[/tex].

The perimeter of a square is 24 inches. Complete the equation and solve to find the length of each side, s.
Answer:
s = 6
Step-by-step explanation:
We know a square has all equal side lengths. So we would divide the square by four to get one side length.

Linear graph and parabola. They intersect at negative 1, negative 5 and 2, negative 2
Group of answer choices
y = x2 − 6
y = −x − 4
y = x2 + 6
y = x + 4
y = x2 + 4
y = −x + 4
y = x2 − 6
y = x − 4
An explanation would also be appreciated!
Answer:
y = x^2 - 6 and y = x - 4
Step-by-step explanation:
It's x^2 - 6, because the parabola was moved 6 down, and positive slope, so in the linear, x is positive

Please help me with these questions in algebra 1 and show work:
Answer:
I’m not gonna show you a graph but these instructions should help…
For the first equation.
You have
5y = -3x + 15
So we have to put it in y=mx + b format.
We can isolate y.
Divide 5 on both sides.
y = -3/5 x +3
You have your equation right htere.
The y intercept (b) here is 3 following the format y=mx +b
So now you plot a point on (0,3) since thats your Y- intercept, first point of contact on the y axis. Now for the slope. Slope goes by rise / run. Think of it as you get out of bed, you have to get up first before you run off to whatever you do.
Now you can just follow the instructions give, -3/5 is -3 rise and 5 run. Since a -3 rise is going down, we do down since its a negative slope here.
Starting from (0,3) you go down 3 units, then at that point go to the RIGHT 5 units. You should have a plotted point on, (5,0). Now following the postulate, if two lines exists in a plane that a line is created, draw a line using the 2 points from (0,3) to (5,0). (Draw throguh the whole thing, not segment and make sure it fills up the whole coordinate plane)
That is your equation.
For the second equation its the same thing, but this time it’s an inequality.
It’s the same gist and the equation is already simplified due for you!
Start on the y- intercept which is -2, or (0,-2)
Now since it’s a positive slope, because its 1/2, rise 1, run 2. From (0,-2) rise up 1 and then run two units to the RIGHT.
You should end up with, (2, -1)
Construct a line throught he two points (not segment line, fill the whole plane).
Now since its an inequality, we don’t stop there.
It’s a less then sign so when constructed the line that fills the whole plane.
You have to shade the bottom RIGHT of your screen that has a line throguh it.
So basically a line is made though two points and you have the whole plane covered. Shade in the bottom part WITHOUT crossing over the line.
Mercury has a mass of 3.30 * 10 23 kg.
Mars has a mass of 6.42 x 10 23 kg.
How many times more massive is Mars than Mercury?
51x 10 23 kg
51
1.95 10 23 kg
1.95
Answer:
Option (4)
Step-by-step explanation:
Mass of Mercury = 3.3 × [tex]10^{23}[/tex] kg
Mass of Mars = 6.42 × [tex]10^{23}[/tex] kg
Therefore, ratio of the masses of Mars and Mercury = [tex]\frac{6.42\times 10^{23} }{3.30\times 10^{23}}[/tex]
= 1.95
[tex]\frac{\text{Mass of Mars}}{\text{Mass of mercury}}=1.95[/tex]
Mass of Mars = 1.95 × (Mass of Mercury)
Therefore, mass of Mars is .95 times more than Mercury.
Option (4) will be the answer.

[tex]C = \frac{1}{4}n( \: a(1) \: + \: a(2) \: ) \\ [/tex]
Multiply sides by 4
[tex]4 \times C = 4 \times \frac{1}{4}n( \: a(1) + a(2) \: ) \\ [/tex]
[tex]4C = n( \: a(1) + a(2) \: )[/tex]
Divided sides by n
[tex] \frac{4C}{n} = \frac{n}{n}( \: a(1) + a(2) \: ) \\ [/tex]
[tex] \frac{4C}{n} = a(1) + a(2) \\ [/tex]
Subtract sides - a (2)
[tex] \frac{4C}{n} - a(2) = a(1) + a(2) - a(2) \\ [/tex]
[tex] \frac{4C}{n} - a(2) = a(1) \\ [/tex]
[tex]a(1) = \frac{4C}{n} - a(2) \\ [/tex]

which point on the number line represents the product (-4 )(-2)(-1)
Answer:
Shown in the image
Step-by-step explanation:
The number line
It's a graphic representation of the real numbers, usually centered at the value 0 and where the positive numbers running to the right, the negative numbers running to the left.
The product (-4)(-2)(-1) can be operated by multiplying the signs apart from the magnitudes. Recall an odd number of negative signs results in a negative number:
(-) * (-) * (-) = -
The product of the magnitudes is 4*2*1=8. Thus the result is -8.

?% of $8,000,000 = $1,600,000
Answer:
20%
Step-by-step explanation:
To solve, we can calculate how much 1,600,000 is of 8,000,000 as a decimal and then solve from there.
Let's say our missing value is x.
x of 8,000,000 = 1,600,000
"x of something", in this case, can be rephrased as "x * something", so we have
x * 8,000,000 = 1,600,000
divide both sides by 8,000,000 to isolate x
x = 1,600,000/8,000,000 = 0.2
to convert from a decimal to percentage, multiply by 100
0.2 * 100 = 20
20% is our answer
