Answer:
w+6=8 and w=2
Step-by-step explanation:
2(w+6) = 16
divide by two on both sides to remove the 2
w+6=16/2
w+6=8
-6 (remove six from both sides)
w=2
Someone help please? its late.
Answer:
It would be 10 units
you can use the midpoint formula.
The area of the region between the lines y = x + 6, x = 1 and y = 0 is:
A 49 units?
B. 49/2 units squared
C.42 units squared
D. 21 units squared
E.cannot be determined
9514 1404 393
Answer:
B. 49/2 units squared
Step-by-step explanation:
The area is that of a triangle 7 units wide and 7 units high. Its area is given by the formula ...
A = 1/2bh
A = (1/2)(7 units)(7 units) = 49/2 units squared
Miguel has a ball of modeling clay that has a diameter of 3.5 centimeters. The cylindrical container it is placed in has a base area of 7.1 square centimeters and a height of 5 centimeters. What is the volume of empty space in the container?
Answer:
48.1 cubic meters or 48100000 cubic centimeters
Step-by-step explanation:
Firstly we need to find the radius.To find that we divide the diameter by two.3.5÷2=1.75
Volume of Cylinder=Pi×radius squared×height
Lastly 3.14×1.75×1.75×5=48.1

Answer:
it's the second choice (3=3)
Answer:
y = - x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (3, 1)
m = [tex]\frac{1-3}{3-1}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , then
y = - x + c ← is the partial equation
To find c substitute (1, 3 ) into the partial equation
3 = - 1 + c ⇒ c = 3 + 1 = 4
y = - x + 4 ← equation of line
Jason purchased three different sizes of candy at the store. The
medium candy was twice as expensive as the small candy. The large
candy was $5 more than the medium candy. He spent a total of $30 on
candy. Write and solve an equation to determine the cost of the small
candy.
Answer: $5
Step-by-step explanation:
Let the small candy be represented by x.
The medium candy was twice as expensive as the small candy. This will be: = 2×x = 2x
The large candy was $5 more than the medium candy. This will be: = 2x + 5
Since Jason spent a total of $30 on
candy, the cost of the small candy will be:
x + 2x + 2x + 5 = 30
5x + 5 = 30
5x = 30 - 5
5x = 25
x = 25/5
x= 5
The small candy cost $5
what about these 2 ?
Answer:
11. A) 12
12. D)11
Step-by-step explanation:
11. We substitute x with 12 in 3(x)-11.
3(12)-11=
36-11= 25
We substitute x with 12 for the second equation (x+13).
12+13=25
Both answers match so the answer for #11 is 12.
12.We substitute x with 11 in 4(x)-4.
4(11)-4=
44-4=40
We substitute x with 11 for the second equation (2(x)+18)
2(11)+18=
22+18=40
Both answers match so the answer for #12 is 11.

Q1 - Finding simple interest
Find the simple interest on a loan of:
£7500 borrowed for 6 years at a
rate of 12% p.a.
interest = £
Answer:
£ 5400
Step-by-step explanation:
P = £ 7500
r = 12% = 0.12
t = 6 years
Simple Interest = P*r*t
= 7500 * 0.12 * 6
= £ 5400

What are the transformations on the following
function, f (x) = -2 log4 (x + 5) - 4?
Answer:
8
Step-by-step explanation:
= f (x) = -2 log 4 (x + 5) - 4
= 4 (-2 + 5) - 4
= So you do -2 + 5 because they are in ( ) so you do it first so (-2 + 5) = 3
= So now you have 4 (3) - 4
= You do 4 and (3) because when you have a 4 by a ( ) that means you multiply.
= 4 (3) which is the same as 4 × 3 which is 12.
= then you do 12 - 4 which is 8.
= 8 is your answer.
I hope this helps.

Step-by-step explanation:
A glassblower can produce several sets of simple glasses in about 3 hours. When the glassblower works with
an apprentice, the job takes about 2 hours. Write an equation that can be used to find the amount of time t, in
hours, it would take for the apprentice to make the same number of sets of glasses when working alone.
Using the together rate, it is found that it would take the apprentice 6 hours to make the same number of sets of glasses when working alone.
What is the together rate?The together rate is the sum of each separate rate.
In this problem, the rates are:
Glassblower: 1/3.Apprentice: 1/x.Together: 1/2.Hence, applying the equation for the together rate:
[tex]\frac{1}{2} = \frac{1}{x} + \frac{1}{3}[/tex]
[tex]\frac{x + 3}{3x} = \frac{1}{2}[/tex]
[tex]2x + 6 = 3x[/tex]
[tex]x = 6[/tex]
It would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

a cone is a solid made from a disc, a point not in the same plane as the discs and all points between them. true or flase?
Answer:
False.
Step-by-step explanation:
A cone is not a solid made from a disc, a point not in the same plane as the discs and all points between them.
Mathematically, the volume of a cone is given by the formula;
[tex] V = \frac{1}{3} \pi r^{2}h[/tex]
Where;
V is the volume of the cone.
r is the radius of the base of the cone.
h is the height of the cone.
Answer: true
