Helpp
Answer:
A
Step-by-step explanation:
Two sides of an obtuse triangle measure 12 inches and 14 inches. The longest side measures 14 inches.
What is the greatest possible whole-number length of the unknown side?
2 inches
3 inches
7 inches
9 inches
Answer:
7
Step-by-step explanation:
The greatest possible whole-number length of the unknown side is 9 inches, option fourth is correct.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have:
Two sides of an obtuse triangle measure 12 inches and 14 inches. The longest side measures 14 inches.
As we know, in the triangle, the sum of the two sides is equal and greater than the third side.
Mathematically,
x + y ≥ z
Here x, y, and z are the sides of the triangle.
12 + 14 ≥ x
x ≤ 26
The greatest possible whole-number length of the unknown side is 9 inches.
Thus, the greatest possible whole-number length of the unknown side is 9 inches, option fourth is correct.

A family of four drove from San Francisco to New York. They drove the same number of miles each 6 days. How many miles did they drive each day? How can you interpret the remainder?
Answer:
Step-by-step explanation:
Approximate distance between San Francisco and New York = 2903 miles
Number of family members = 4
Approximate distance to be covered by each member per day = [tex]\frac{2903}{4}[/tex] = [tex]725\frac{3}{4}[/tex] miles
Number of days to drive = 6 days
Total distance to be covered by each member each day = [tex]\frac{2903}{4}\times \frac{1}{6}[/tex]
= [tex]\frac{2903}{24}[/tex]
= [tex]120\frac{23}{24}[/tex] miles
Therefore, each family member has to drive the car for 120 miles per day approximately.
23 miles remaining will be covered by any one of the family members on the last day.

Hey you! Yes you! You are awesome! Can you help me?
Answer:
a = -40
Step-by-step explanation:
In order for a system of equations to have infinitely many solutions, the equations must have the same line when graphed. Knowing this, it also means that the equations equal the same thing - they're just written differently. Also, remember that a constant term is just a number with no variables.
First, I would organize the second equation into standard format just like the first one (moving the x and y terms to the left side):
[tex]6x = 16 + a -15y\\6x + 15y = 16 + a[/tex]
Then, by comparing the x and y terms in both equations, we can see that the second equation is just the first equation multiplied by 3. (Notice how 2x times 3 is 6x, and 5y times 3 is 15y.) So, we would need our constant on the left hand side to do the same, to equal -8 times 3, or -24.
Thus, we would need to find what added to 16 equals -24, and we can do this with a simple algebra equation:
[tex]a + 16 = -24\\a = -40[/tex]
Therefore, a would need to equal -40 in order for the system to have infinitely many solutions.
Write an equation in point slope form of the line that passes through the point -4, 5 and has the slope of one.
Answer:
y - 5 = x + 4
Step-by-step explanation:
Use point slope form, y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line
Plug in the given point and slope:
y - y1 = m(x - x1)
y - 5 = 1(x + 4)
Simplify:
y - 5 = x + 4
So, the point slope form of the line is y - 5 = x + 4
A rectangular block of metal is 25cm long, 11cm wide and 9cm high. The metal block is melted down and all of the metal is used to make a cube. Work out the length of each side of the new cube formed
Answer:
29.03 cm
Step-by-step explanation:
Step one:
given
A rectangular block of metal is
25cm long
11cm wide and
9cm high.
The volume of the block is
= 25*11*9
= 2475cm^3
Required
The dimension of an equivalent cube
we know that volume of cube
v=l^3
24475=l^3
cube root both sides
l= ∛24475
l= 29.03 cm
Answer:
13.5cm

how do you calculate the profit
Answer:
total money - total expences = profit
Total money is the money you make, so say you made $50
Total expences is how much you paid to have that thing made, say $10
50 - 10 = 40
the profit would then be $40

Answer:
Step-by-step explanation:
-20z+8+(-6)
-20z+2
Answer:
it is (-20z+8)+(-24)
Step-by-step explanation:
the operation that is done here is multiplication. so, now you can just multiply each term, -5z times 4, 2 times 4, -6 times 4.
-5z times 4: -20z
2 times 4: 8
-6 times 4: -24

Louisa states that the solution to the equation One-fourth x minus 3 = StartFraction 3 Over 8 EndFraction x + 4 is x = 56. She verifies her solution using the steps below.
Equation: One-fourth x minus 3 = StartFraction 3 Over 8 EndFraction x + 4
Step 1: One-fourth (56) minus 3 = StartFraction 3 Over 8 EndFraction (56) + 4
Step 2: 14 minus 3 = 21 + 4
Step 3: 11 = 25
Which statement most accurately describes Louisa’s error?
Louisa made an error when determining the original solution of x = 56.
Louisa made an error when substituting the solution in for x.
Louisa made an error when multiplying 56 by One-fourth and by StartFraction 3 Over 8 EndFraction.
Louisa made an error when adding or subtracting.

Evaluate-8÷2+12×9-4×6
Answer:
Step-by-step explanation:
Use PEDMAS {Parenthesis ; Exponent ; Division ; Multiplication ; Addition; Subtraction }
8÷2 + 12*9 - 4*6 = 4 + 12*9 - 4*6 {Division}
= 4 + 108 - 24 {Multiplication}
= 112 - 24 {Additon}
= 88
Answer: 88
Step-by-step explanation:
Evaluate using PEMDAS.
P = Parenthesis; There are no parenthesis in this expression
E = Exponents; There are no exponents in this expression
M = Multiplication; 12 x 9 = 108, 4 x 6 = 24
D = Division; 8/2 = 4
A = Addition; 4 + (12 x 9) = 112
S = Subtraction; (4 + (12 x 9)) - (4 x 6)
112 - 24 = 88
