Answer:
Each student gets 1.75 ft of ribbon
Step-by-step explanation:
r × 4 = 7
First, divide the given factor by itself in order to get the variable by itself.
4 ÷ 4
Next, divide the product by the given factor bc what you do to the left, you must do to other side.
7 ÷ 4
Last, right down your new equation and find you solution.
New Equation: r = 1.75
Answer:
Step-by-step explanation:
f(x) =2x+1 and g(x)=x²-7, find (f-g) (x)
help!!
Answer:
(f-g)(x)=2x+1-x^2+7
=2x-x^2+8
=-(x^2-2x-8)
=-(x^2-4x+2x-8)
=-{x(x-4)+2(x-4)}
=-(x+2)(x-4)
Which one is it?
a) <
b) =
c) >
Answer:
B) =
Step-by-step explanation:
When you calculate the equation on the left (32 + 4 = 36) then the one on the right (6 × 6 = 36), and they will be both be equal.

Keith and his little brother, Sean, carried the bags of groceries into the house after their
grandmother went shopping. Because Keith is older, he carried 3 times as many bags as
Sean.
Pick the diagram that models the ratio in the story.
Keith
Sean
Keith
Sean
If Keith carried 6 bags of groceries, how many bags were there altogether?
bags
Answer:
8 bags altogether
Step-by-step explanation:
Again, without a photo, I can't choose the diagram. Very sorry.
k is Keith, s is Sean
k = 3s
substitute in bags Keith carried and solve for s
6 = 3s
divide both sides by 3
s = 2
Keith carried 6, Sean carried 2,
6 + 2 = 8 bags total

If f(x) = 3x + 2, what is f(5)?
Answer:
17
Step-by-step explanation:
f(x) = 3x + 2
Let x=5
f(5) = 3*5 + 2
Multiply first
= 15+2
Then add
= 17
6
(
f
+

)
6(f+4) + 2(f+4)
Use the distributive property:
6f+24 + 2f + 8
Now combine like terms:
8f +32
The answer is 8f + 32
Answer:
8 f + 32
Step-by-step explanation:
6 ( f + 4 ) + 2 ( f + 4 )
Distribute
6 × f + 6 × 4 + 2 × f + 2 × 8
6 f + 24 + 2f + 8
Collect like terms

Eric kept a record of the number of hours it rained each day from Monday to Saturday in a particular week. This information was shown through the following Bar Graph.
How does the Bar Chart misrepresent the data?
A. The scale along the vertical axis is divided into unequal intervals.
B. The categories along the horizontal axis are missing Friday.
C. The widths of the bars are not equal.
D. The heights of the bars representing Monday and Thursday are not same.
Answer:
The answer is B because the title says each day but Friday is missing. Also, the graph is not set up properly as they should be closer together so it could possible be C but, I doubt it.
Answer:
B. well its just not there
Toula has just baked a cake in the shape of a rectangle. She
wants to divide the cake into two right-angled triangles by
cutting along a diagonal of the cake. Toula is then going to place
a cake ribbon around the outside of each of the two triangular
pieces of cake. If the length of the cake is 32 cm and its width is
24 cm, how much cake ribbon will she need to buy, giving your
answer to an appropriate accuracy.
Ellie made an octagon and used a ruler so each side is the same length. Her octagon has a perimeter of 80 inches. What is the length of each side? ___ (your answer) inches
Answer:
Each side is 10 inches because the perimeter is 80 inches, you will have to divide 80 by 8 because octagon is a shape with 8 sides. So 80 divided by 8 is 10..... So the answeer is 10 inches.
Step-by-step explanation:
80÷8=10

Find the volume of the sphere.
Either enter an exact answer in terms of 1 or use 3.14 for and round your final answer to the nearest
hundredth.5
Answer:
The volume of the sphere is 523.60
Step-by-step explanation:
The formula for volume of a sphere is :
V = [tex]\frac{4}{3} \pi r^{3}[/tex]
The radius of this sphere is 5, so let's plug that into our equation.
V = [tex]\frac{4}{3}[/tex] · [tex]\pi[/tex] · [tex]5^{3}[/tex]
≈ 523. 59878
Rounded to the nearest hundreth that is 523.60.
Hunter is 9 years older than 3 times the age of his nephew.
Hunter is 33 years old. How old is his nephew?
Answer:
Hunter's nephew is 8 years old.
Step-by-step explanation:
We could set up an expression to represent the situation, then solve for the nephew's age. The age of the nephew should be represented by X.
3x + 9 = 33
To get 3x by itself, subtract 9 from both sides.
3x + 9 - 9 = 33 - 9
3x = 24
To get X alone, divide by 3 on both sides.
24 divided by 3 is 8. Hunter's nephew is 8 years old.
Find the value of each variable
Answer:
Z = 65 Y = 115
Step-by-step explanation:
z+115 = 180
z=65
y + 65 +100+80= 360
y+245 = 360
y=115
Answer:
y = 115°
z = 65°
Step-by-step explanation:
*IMPORTANT* Straight line = 180° & Squares = 360°
1) 180° - 115° = 65°
z = 65°
2) 360° - 100° - 80° - 65° = 115°
Also, interior angles = exterior angles

PLEASE HELP! Math (recursive sequences)
Answer:
a₄ = 123
Step-by-step explanation:
a₁ = 1
a₂ = (1)² + 2
a₂ = 3
a₃ = (3)² + 2
a₃ = 11
a₄ = (11)² + 2
a₄ = 123
Plot the coordinates of the point:
(a) whose co-ordinate is -5 and which lies on y axis.
(b) Which lies on x and y-axis both.
(c) whose abscissa is 3 and which lies on x-axis in cartasian plance.
Answer:
First, a regular point is written as a coordinate pair (x, y).
If the point lies on the x-axis, then we have y = 0
if the point lies on the y-axis, then x = 0
And x is the abscissa, y is the ordinate.
The points will be graphed at the end.
a)
Ordinate = -5, then y = -5
and it ies on the y-axis, then x = 0
So this point is represented by A = (0, -5)
b)
Lies on the y-axis and in the x-axis, then x = 0 and y = 0, so the point is represented by B = (0, 0)
c)
The abscissa is 3, so x = 3, and the point lies on the x-axis, so y = 0
Then this point is represented by C = (3, 0)

Answer:
Step-by-step explanation:
Write an equation of the line that passes through the point (4,5) and has a slope of -2.
Answer:
y = - 2x + 13
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 )
Here m = - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute (4, 5) into the partial equation
5 = - 8 + c ⇒ c = 5 + 8 = 13
y = - 2x + 13 ← equation of line
Answer:
Step-by-step explanation:
slope=-2
now using slope intercet formof equation of straight line,we get
y=mx+b
or, y=-2x + b
y + 2x =b
2x + y=b ...................... eq(i)
since the line passes through the point (4,5) it satisfies the equation (i)
y=5 and x=4 so,
equation is 2x +y =b
2*4 + 5=b
8+5=b
13=b
substituting the value of b in eq(i)
2x + y=b
2x + y=13
2x + y-13=0 is the required equation of the line.
