Answer:
Step-by-step explanation:
21 feet below is written as -21
9 feet up is written as +9
So we have -21 + 9 = -12 or 12 feet below sea level
Hey hope someone can figure this out hopefully it's not that hard.
A chocolate box has the shape of a prism with a base that is a
rhombus. Each side length of the rhombus is 3.6 cm.
The angles between adjacent sides of the base are 60° and 120°.
The prism is 10.8 cm long.
a) Draw a net for this box.
b) How is your net different from the cardboard net from
which the box is made? Explain.
Part (a)
See the diagram below for the net for this box. We have two rhombuses that are the two bases of the rhombic prism. The six rectangles form the lateral sides.
In geometry, a net is effectively the outer surface of a 3D object, but it has been laid flat on a plane. Think of unwrapping a present without throwing any pieces away. The net would be the wrapping laid out flat. As another example, a net of a cardboard box would be laying the box flat. So you're unfolding the box. This is mentioned in part (b).
====================================================
Part (b)
The main difference from this net compared to a net for a cardboard box is that everything is a rectangle for a cardboard box. This is because a cardboard box folds up into a rectangular prism.
So in the diagram below, you'll replace each rhombus with a rectangle. You'll make all four angles 90 degrees.

Answer:
x = 8, y = 4
Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , thus
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{3} }{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
x × [tex]\sqrt{3}[/tex] = 8[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
x = 8
--------------------------------------------------------------
To find y use the tangent ratio in the right triangle and the exact value
tan60° = [tex]\sqrt{3}[/tex] , thus
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{4\sqrt{3} }{y}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by y )
4[tex]\sqrt{3}[/tex] = y × [tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
y = 4

Step-by-step explanation:
(4x^2 −2x−6)- (7x−9)
=(4x^2-2x-6-7x+9)
=(4x^2-9x+3)
4x^2-9x+3is the answer
Answer:
4x² - 9x + 3
Step-by-step explanation:
(4x² - 2x - 6) - (7x - 9)
4x² - 2x - 6 - 7x + 9
4x² - 2x - 7x - 6 + 9
4x² - 9x + 3

1 Which is the equation of a line that has a slope of and passes through point (2, -3)? O y = 1/2 X - 4 O y-x-2 O y=;x+2 O y=zx+3
Answer:
y = (1/2)x - 4
Step-by-step explanation:
every equation has a slope of (1/2)
Then we should only consider the passing through point.
y = (1/2)x - 4
R.H.S : (1/2)x - 4. (substitute x= 2)
= -3
= L.H.S
it is passing through point (2,-3)
The equation of the line is y = (1/2)x - 4.
The correct option is (A).
What is slope?A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
As per the given data:
We are given the slope of the line.
We are also given the point through which the line passes.
Slope of the line = 1/2
Point through which the line passes = (2, -3)
From the slope-intercept form, the equation of any line can be written as:
y = mx + c
where m is slope and c is the y intercept
m = 1/2
y = (1/2)x + c
Line passes through (2, -3)
-3 = (1/2) × 2 + c
c = -4
The equation of the line is y = (1/2)x - 4
Hence, the equation of the line is y = (1/2)x - 4

Si la probabilidad de que un recién nacido sea niño es de 1 de dos opciones, representado en fracción 1/2, ¿Cuál es la probabilidad de que un recién nacido sea niña?
Answer:
1/2 o 50%
Step-by-step explanation:
debemos partir de la presuncion que un bebe puede ser niño o niña uinicamente, o sea la P(niño) + P(niña) = 1
no existen los bebes que son niños y niñas al mismo tiempo, eso quiere decir que es una opcion o la otra
P(niña) = 1 - P(niño) = 1 - 1/2 = 1/2 = 0.5 = 50%

What is the equation of the line that passes through the point (3, -3) and has a
slope of o?
Answer:
y = -3
Step-by-step explanation:
point = (3, -3)
slope (aka m) = 0
y = mx + b
-3 = (0)(3) + b
b = -3
y = (0)x - 3
y = -3

Determine the constant of proportionality for the graph.
PLEASE HELP ME!!!!
Answer:
[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
On your recent question- you stated that when the x value was 10, the y value was 2. The graph started at the origin. To find the constant of proportionality, use the equation [tex]\frac{rise}{run}[/tex]. In this case, the "run" was 10, since it went +10 from 0. The "rise" was 2, since it went +2 from 0.
[tex]\frac{2}{10} = \frac{1}{5}[/tex] simplified.

slope from two points
Answer:
[tex]\frac{12}{7}[/tex]
Step-by-step explanation:
use the formula [tex]\frac{y - y'}{x - x'}[/tex]
so you would get
[tex]\frac{4 - (-8)}{0 - (-7)}[/tex]
Those negatives becomes a positive and you get 4+8 = 12 and 0+7 = 7
you final answer would be [tex]\frac{12}{7}[/tex]
Answer: I am pretty sure the answer is D.
Step-by-step explanation:
so this is how u find the slope from two points... You have (-7,-8) and (0,4) you then take -7 and subtract that by 0 so -7-0 and then -8-4. and -7-0/-8-4 = 7/12. plz tell me if I am wrong.

09) The ratio of the number of jackfruit in baskets P, Q
and R is 6:2:5. The total number of jackfruit
in basket Pis 48 more than the number of
jackfruit in basket Q. Calculate the total number
of jackfruits in the three baskets.
A 121 B 144 C 156 D 169
Answer:
156 jackfruits
Step-by-step explanation:
Let there are 6x jackfruit in baseket P, 2x in basket Q and 5x in basket R.
The total number of jackfruit in basket P is 48 more than the number of jackfruit in basket Q. ATQ,
6x = 48 + 2x
Solving for x.
6x - 2x = 48
4x = 48
x = 12
Jackfruits in basket P = 6x = 6(12) = 72
Jackfruits in basket Q = 2x = 2(12) = 24
Jackfruits in basket R = 5x = 5(12) = 60
Total no of jackfruits = 72 + 24 + 60
= 156
So, there are 156 jackfruits in the three baskets.
