The expression that is equivalent to the expression illustrated is 1/12g - 18.
What is an expression?It should be noted that an expression is used to show the relationship between the variables.
The expression will be illustrated as:.
= 5/4g - 3 - 7/12g - (1/3g + 15)
= 5/4g - 3 - 7/12g - 1/3g - 15

For the square ABCD, it is known that | AB| = | AC| and |DA| = |DC| and corner ABC =
corner CDA. One of the corners of this square is 150 degrees. Find the sizes of the three remaining angles of the square ABCD.
Answer:
∠BAD = 150°∠ABC = 48°∠BCD = 114°∠ADC = 48°Step-by-step explanation:
Given quadrilateral ABCD with AB≅AC, DA≅DC, ∠ABC≅∠ADC, and one of the corner angles equal to 150°, you want the measures of all corner angles.
SetupThe given congruent angles and sides are marked in the attached diagram. If we let ∠ACB = x and ∠ACD = y, we can write some equations involving the sums of the various angles.
First of all, we note that both triangles are isosceles. That means ...
∠ABC≅∠ACB = x∠DAC≅∠DCA = yThe sum of angles in ∆ACD must be 180°, so we have ...
x + 2y = 180°
We know that the isosceles triangle base angles cannot exceed 90°, so the angles at corners B and D cannot be 150°. That leaves two possibilities:
(a) Corner angle C is 150° ⇒ x + y = 150°
(b) Corner angle A is 150° ⇒ (180°-2x) +y = 150°
Solution(a) Corner C is 150°
This makes the system of equations for x and y be ...
x +2y = 180°x +y = 150°Subtracting the second from the first gives y = 30°, and substituting that value for y gives x = 120°. We already know x is the base angle of an isosceles triangle, so cannot have that value. This possibility is eliminated.
(b) Corner D is 150°
This makes the system of equations for x and y be ...
x +2y = 180°(180° -2x) +y = 150°The second of these equations can be rearranged to ...
2x -y = 30°
Adding twice this to the first equation, we have ...
2(2x -y) +(x +2y) = 2(30°) +(180°)
5x = 240°
x = 48°
Substituting for x in the second equation gives ...
2(48°) -y = 30°
96° -30° = y = 66°
As we noted in the solution part (a), corner angle C is the sum of x and y:
∠BCD = x +y = 48° +66° = 114°
Corner anglesThen the corner angles are ...
∠BAD = 150°∠ABC = 48°∠BCD = 114°∠ADC = 48°The attached figure is drawn to scale.

Answers:
a) 32500
b) 0.00604
c) 2.4 * 10^6
d) 1.47 * 10^(-3)
===================================================
Explanation:
The exponent over the 10 tells us how many spaces to move right or left. If the exponent is positive, we move right. If negative, we move left. Think of a number line.
For part (a), the exponent is 4. So we move the decimal point 4 spaces to the right.
The 3.25 then becomes 32500
--------------
In part (b), the exponent -3 means we move 3 spots to the left to go from 6.04 to 0.00604
---------------
Part (c)
Place the decimal point between the first two digits and erase the zeros to get 2.4
Then we need to move the decimal point 6 spots to the right to get back to 2,400,000 again
Therefore we can say 2,400,000 = 2.4*10^6
---------------
Part (d)
Place the decimal point just after the first nonzero digit, and erase the zeros to the left to get 1.47
We must move the decimal point 3 spots to the left to go from 1.47 back to 0.00147 again
It means 0.00147 = 1.47*10^(-3)

What is slope interception form?
Y=mx+b, where m is the slope and b is the y-intercept, is the slope intercept form. The graph of the linear equation can be drawn on the x-y coordinate plane using this form of the equation.
For the given question we are given,
slope (m) = 2/3
and we are also given the point that the line passes through to be,
(-1,3).
that is
(x,y)=(-1,3)
x=-1
y=3
we, know that slope interception form is of the form,
y=mx+c
substituting the value of m (slope) and the point (-1,3) we get
3=(2/3)*(-1)+b
= 3= -2/3 +b
= 3+2/3=b
= (9+2)/3=b
= 11/3=b
from this we get b=11/3
now substituting this again in
y=mx+b
we get
y=(2/3)x+(11/3)
Hence the second option [tex]y=\frac{2}{3}x +\frac{11}{3}[/tex] is correct.

Step-by-step explanation:
"with replacement" is important.
that means that the mixture of the marbles and therefore the chances to pull certain marbles does not change with the previous pull.
a probability is always
desired cases / totally possible cases
we have 14 marbles in the bag
4 orange
2 green
8 purple
the probability to pull an orange marble is therefore
4/14 = 2/7
the probability to pull a green marble is therefore
2/14 = 1/7
the probability to pull a purple marble is therefore
8/14 = 4/7
a.
a green marble is pulled AND then a purple marble is selected.
we need to combine both probabilities for one combined event :
1/7 × 4/7 = 4/49
b.
a purple marble and then a green marble is selected.
4/7 × 1/7 = 4/49
since we replace the marbles after every pull, both probabilities are the same, of course.
every pull has the same probability for each desired event.
c.
2 orange marbles are selected.
2/7 × 2/7 = 4/49
d.
2 non-orange marbles are pulled
there are 10 non-orange marbles. so this is
10/14 × 10/14 = 5/7 × 5/7 = 25/49
the following group of equations represents which type of system {x^2 + y^2 = 9 x^2/16 + y^2/9 =1
The given group of equations represents a system of non-linear equations.
How to know if an equation is linear or nonlinear?A mathematical equation must take the form y = m x +b in order to be classified as a linear function (in which m is the slope and b is the y-intercept). This form cannot be satisfied by a nonlinear function.
Only first degree variables and terms that contain the products of variables are present in a linear equation.
However, in the case of nonlinear equations, either the equation comprises a product of variables or at least one of the variables is not of the first degree.
If the graph of an equation is a straight line, the equation is linear. Otherwise, if the power of x is more than one, then it is nonlinear.
The given equations has the degree more than 1 and their graph is also not a straight line.
Hence, the given group of equations represents a system of non-linear equations.

suppse that you buy and exerice ball with diameter of 85 cm and your brother buys and exercise ball with 65 cm what is the diffrence bewtween the volume and surface are of both balls? round to the nearest 100
Given:
• Diameter of my ball = 85 cm
• Diameter of my brother's ball = 65 cm
Let's find the difference between the volume of the both balls and also let's find the difference between the surface area of both balls.
A ball has the shape of a sphere.
Therefore, we have the following formulas:
• Volume of a sphere formula:
[tex]V=\frac{\pi d^3}{6}[/tex]• Surface area of a sphere formula:
[tex]A=\pi d^2[/tex]Where d is the diameter.
• Now, to find the difference between the volume of both balls, we have:
[tex]V_1=\frac{\pi d^3}{6}=\frac{\pi85^3}{6}=321555.09\approx321555\text{ cm}^3[/tex]The volume of my ball is 321555 cubic cm.
[tex]V_2=\frac{\pi *65^3}{6}=143793.3\approx143793\text{ cm}^3[/tex]Volume of my brother's ball is 143793 cubic cm.
Therefore, to find the difference between the volume of both balls, we have:
V = V1 - V2 = 321555 - 143793 = 177762 cm³ = 177800 cm³
The difference between the volume of both balls is 177800 cm³
• Now for the surface area, we have:
[tex]A_1=\pi d^2=\pi *85^2=22698.01=22698\text{ cm}^2[/tex]The surface area of my ball is 22698 cm²
For surface area of my brother's ball:
[tex]A_2=\pi d^2=\pi *65^2=13273.23\approx13273\text{ cm}^2[/tex]The surface area of my brother's ball is 13273 cm².
Difference of surface areas:
A = A1 - A2 = 22698 - 13273 = 9425 cm² = 9400 cm²
Therefore, the difference between the surface area of both balls is 940O cm².
ANSWER:
• Difference between volume of both balls= 177800 cm³
• Difference between the surface area of both balls = 9400 cm²

Answer:
Explanation:
Given the function:
[tex]G(x)=x^2[/tex]The graph of G(x) is wider than the graph of F(x), so we can conclude that G(x) has been stretched vertically by a factor greater than 1 to obtain F(x).
Furthermore, G(x) was translated upwards by 2 units when we compare the vertices.

at 3:00 am the temperature was -8 degrees.By early evening, the temperature rose 25 degrees at late day the temperature dropped 5 degrees. What was the late day temperature?
According to the problem:
• At 3:00 am the temperature was -8°.
,• Then, it rose 25 degrees. ,This implies a sum.
,• At last, it dropped 5 degrees. ,This implies a subtraction.
Remember that "rising" shows a positive direction and "dropping" shows a negative direction. Following this rule, we can form the following expression
[tex]T=-8+25-5[/tex]There you can observe that the initial temperature (-8) increased (+)25, and then decreased (-)5.

Answer:
Part A: 0.8x
Part B: 80% of the original price.
Explanation:
Part A:
The store sells the boots at a sale price of 20% off, meaning the price of the shoes is 100% - 20 % = 80% of the original price. If we call x the original price, then the sale price would be
