Andrea was asked to find the value of –32 × 9 × 5/4 . How can Andrea make this problem easier to compute?
Answer:
divide the 32 by 4:
then the equation becomes:
8 x 9 x 5 = 360
this is the same as 32 x 9 x 5/4 = 360
The value of given expression is -360.
What is Equation?An equation is a statement that proves that two expressions connected by the equals sign "=" are equal.
In algebra, an equation is a condition on a variable. It only applies to a specific variable value.
Algebra takes into account two prominent families of equations: linear equations and polynomial equations.
Given -32 x 9 x 5/4
since equation is in multiple form
32 is divided by 4 completely
32/4 = 8
and equation become
-8 x 9 x 5
follow the multiplication we get
-360.
Hence the product is -360.

Find the are of the shaded region
Answer:
[tex] 379.69 \: {ft}^{2} [/tex]
Step-by-step explanation:
Area of the shaded region = Area of the square with side 25 ft - Area of the semicircle with radius (25/2) = 12.5 ft.
[tex] = {(25)}^{2} - \frac{1}{2} \times \pi \times {(12.5)}^{2} \\ \\ = 625 - \frac{1}{2} \times 3.14 \times 156.25 \\ \\ = 625 - 245.3125 \\ \\ = 379.6875 \: {ft}^{2} \\ \\ = 379.69 \: {ft}^{2} [/tex]

In class A, 15 out of the 30 students are girls, and in class B, 24 out of the 40 students are girls. Which class has a higher percentage of girls?
Answer:
Class B
Step-by-step explanation: 15 out of 30 is 50% and 24 out of 40 is 60% because 24 out of 40 is also the same as 12 out of 20. 20*5 = 100, so 12*5= 60. 60>50
If triangle ABC is an equilateral triangle and the measure of angle A is
5x, what is the value of x?
Answer:
A not enough
Step-by-step explanation:
I need to know this ASAP I need to get through this lesson before Friday
Answer:
It is C.
Step-by-step explanation:
So,A triangle is equal to 180 and you would add up the numbers you already have which equal 145.180-145= 35° and thats why the last letter would be 35° in your answer and be correct which would be that m<F=35° is the same as ABC in the last letter. Since,<B is the second letter in ABC and so is <E in DEF and have the same degree that would be the same as well so I hope that helps:)
Answer:
c
Step-by-step explanation:
the angles in a triangle have to add up to 180°
65 + 80 = 145
180-145 = 35
the missing angle is 35°
choice c matches because it has 2 of the same angle measures, which means they all have to be the same

Paul wants to place an ad in a newspaper. The newspaper charges $10 for the first 2 lines of
text and $3 for each additional line of text. Paul's ad is 8 lines long. How much will the ad cost
Answer:
$38
Step-by-step explanation:
$10 × 2= $20
Therefore the first two lines cost $20
$3 for each additional line of text
since the total lines are 8 lines therefore 8 -2=6
$3 × 6=$18
Tolat cost: First two lines + additional lines
$20+$18= $38

Michael has a jar of dimes and nickels there are 152 dimes and nickels in the jar that total $11
Answer:
Michael has 84 nickels and 68 dimes in a jar.
Step-by-step explanation:
Let n = number of nickels
Let d = number of dimes
n + d = 152
5n + 10d = 1100
(5n + 10d = 1100)/5
n + 2d = 220
- n + d = 152
d = 68
n + 68 = 152
- 68 - 68
n = 84
Michael has 84 nickels and 68 dimes in a jar.

A large emerald with a mass of 982.7 grams was recently discovered in a mine. If the density of the emerald is 2.76 grams over centimeters cubed, what is the volume? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.
Answer:
356.05 cm³
Step-by-step explanation:
We are looking for the volume. The formula is density = mass / volume.
If we plug in our numbers, our formula would be 2.76 = 982.7 / V.
Multiply both sides by V and your formula would be (V) 2.76 = 982.7.
Divide both sides by 2.76 and you would get V = 356.05.
The volume of the given large emerald is required.
The volume of the given large emerald that was discovered in the mine was 356.05 cm³. The calculations to find this value is shown below.
Densitym = Mass of object = 982.7 grams
[tex]\rho[/tex] = Density of the material the object is made of = 2.76 grams over centimeters cubed
The relation between mass, volume and density is given by
[tex]V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{982.7}{2.76}\\\Rightarrow V=356.05072\approx 356.05\ \text{cm}^3[/tex]

The solution to which system of equations has an y-value of 0?
(A) x + 2y=-1; y = 3x + 3
(B) 3x – y=2; x + 2y=-1
(C) y= 3x + 3; 2x + 3y=01
Answer:
A)
Step-by-step explanation:
The only system of equation (A) has a y-value of 0.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
To find the solution with a y-value of 0, we need to substitute y=0 in each equation of the system and solve for x.
(A) x + 2y = -1
x + 2(0) = -1
x = -1
y = 3x + 3
y = 3(-1) + 3
y = 0
The solution to system A has a y-value of 0.
(B) 3x - y = 2
3x - 0 = 2
x = 2/3
x + 2y = -1
(2/3) + 2y = -1
2y = -1 - (2/3)
2y = -5/3
y = -5/6
The solution to system B does not have a y-value of 0.
(C) y = 3x + 3
y = 3x + 3 implies that y cannot be 0, so this system cannot have a solution with a y-value of 0.
(D) 2x + 3y = 0
2x + 3(0) = 0
2x = 0
x = 0
x + 2y = -1
0 + 2y = -1
y = -1/2
The solution to system D does not have a y-value of 0.
Therefore, the solution to system A has a y-value of 0.
