Answer:
6/10 and convert that to 3/5 so 3/5 divided by 1/5 will still equal 3/5. so the answer is 3
Step-by-step explanation:
Answer:
Step-by-step explanation:
6/10 gives the decimal 0.6 so Isaac walks 0.6 miles in 1/5 of an hour, his pace held constant. That means Isaac walks 0.6 x 5 = 3 miles in a full hour
(6/10 miles) / (1/5 hour)0.6 miles / (1/5 hour)0.6 miles x 5 / (1/5 hour x 5)3 miles / 1 hourHi I hope you can help me im struggling with this. ((: I'll give you a brainy thing if your right

QUESTION:How many paper cups can be filled completely using all of the water from the full water cooler
ANSWER CHOICE:
36
108
144
216
Answer:
108
Step-by-step explanation:
find the volume of the cooler:
V=πr²h
π×6²×16= 1809.56
find the volume of the cup:
V=πr²(h/3)
π×2²×(4/3)= 16.76
divide the volume:
1809.56/16.76= 107.969
Assuming that the cooler is full to the max, and cups are filled almost to the top, the cooler contains 108 cups of water.
The function f(x) = -x² + 8x-7 is translated five units down. Write the new equation in vertex form and state the vertex.
Answer:
The resulting equation in the vertex form is [tex](y-4)=-(x-4)^2[/tex] having the vertex at the point (4,4).
Step-by-step explanation:
The given function is f(x) = -x² + 8x-7.
As the given function is translated 5 units down, so, subtract 5 units in the given function.
The resulting function, y = f(x) -5
[tex]\Rightarrow y= - x² + 8x - 7 - 5 \\\\\Rightarrow y = - x² + 8x - 12[/tex]
Now converting the obtained equation to vertex form,
[tex]y= - x² + 8x - 12 \\\\\Rightarrow y = -(x^2-8x+12) \\\\[/tex]
Adding and subtraction 4 as
[tex]y= -(x^2-8x+12+4-4) \\\\\Rightarrow y= -(x^2-8x+16-4) \\\\\Rightarrow y= -((x-4)^2-4) \\\\\Rightarrow (y-4)=-(x-4)^2[/tex]
The vertex of the above equation is (4,4).
Hence, on translating five units in the downwards direction, the resulting equation in the vertex form is [tex](y-4)=-(x-4)^2[/tex] having the vertex at the point (4,4).
On translating five units in the downwards direction, the resulting equation in the vertex form is (y-4)=-(x-4)² having the vertex at the point (4,4).
The given function is f(x)= -x²+8x-7.
A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other.
When the shape is moved down by k units, then replace y with y - k.
The function f(x) = -x² + 8x-7 is translated five units down.
That is, y=f(x)-5
y=-x² + 8x-7-5
y=-x² + 8x-12
Subtract 4 on both the sides of an equation, we get
(y-4)=-x² + 8x-12-4
(y-4)=-x² + 8x-16
(y-4)=-(x²-8x+16)
(y-4)=-(x-4)²
Hence, on translating five units in the downwards direction, the resulting equation in the vertex form is (y-4)=-(x-4)² having the vertex at the point (4,4).

Solve the equation 6x+3y=3
Answer:
x=−1/2 y+ 1/2
Step-by-step explanation:
Let's solve for x.
6x+3y=3
Step 1: Add -3y to both sides.
6x+3y+−3y=3+−3y
6x=−3y+3
Step 2: Divide both sides by 6.
6x /6= −3y+3/6
x=−1/2 y+ 1/2

Solve for x: 7 + 4x = 13+ X. Select one: a. x = 1 1/5 b.x=2 x 2 C. X= 4 d. x = 6 2/3
Answer:
7+4x=13+x
4x-x=13-7
3x=6
3 3
x =2
Step-by-step explanation:
because when 7 crosses the equal to sign it becomes negative and when the x from the other side crosses the equal sign it also will become negative which will become 4x-x=13-7
which is 3x=6 so u divide both sides by the coefficient of x which is three which will give u 2
Perpendicular lines create obtuse angles where they intersect.
True
False
Answer:
The answer is false
Step-by-step explanation:
Perpendicular lines create four 90 degree angles thus if you connect the edges you make a square that has four 90 degree corners. Lines that can crate obtuse angles are called intersecting angles. And parallel never touch so they don't make any angles

A garden store sells plants in flats there are six plants in each tray each flat has six trays the garden store sold 16 flats on Saturday and 21 flats on Sunday how many plants did the garden sell in all
Answer:
1332 plants
Step-by-step explanation:
A garden store sells plants in flats there are six plants in each tray each flat has six trays the garden store sold 16 flats on Saturday and 21 flats on Sunday how many plants did the garden sell in all
From the above question
1 tray = 6 plants
6 tray = 1 flat
Hence,
1 tray = 6 plants
6 tray = x plants
= x = 6 × 6 plants
= 36 plants
Hence, 1 flat = 36 plants
We are told: the garden store sold 16 flats on Saturday and 21 flats on Sunday how many plants did the garden sell in all
Total number of flats sold = 16 flats + 21 flats = 37 flats
That number of plants sold =
1 flats = 36 plants
37 flats = x plants
x = 37 × 36 plants
x = 1332 plants

5.2x-y=4.1 1.5x+y=6.7
how to solve this problem
Answer: x=1.6
y=4.2
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
we will add both equations and you see that the y is getting cancelled
6.7x=10.8
x=10.8/6.7= 1.6
now in any equation we will replace x with 1.6
5.2(1.6)-y=4.1
8.3-y=4.1
-y= 4.1-8.3
-y=-4.2 multiply by -1
y=4.2
Answer:
x = 1.61 (Estimated)
y = 4.28 (Estimated)
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
5.2x − y = 4.1
−y = −5.2x + 4.1
y = 5.2x − 4.1
Solve for x:
1.5x + y = 6.7
1.5x + 5.2x − 4.1 = 6.7
6.7x − 4.1 = 6.7
6.7x = 10.8
x = 1.61194
Solve for y:
y = 5.2x − 4.1
y = 5.2 × 1.61194 − 4.1
y = 4.28209

Answer:
x=3
Step-by-step explanation:
for 17.
we have that x=8 as one solution
then we have
x-8=0
so we know that
[tex]f(x)=(x-8)(something)[/tex]
[tex]\frac{f(x)}{x-8}=something[/tex]
so we divide and get that
[tex]something = x^{2} -6x+9x[/tex]
and we can factor it as
[tex](x-3)(x-3)[/tex]
so the other solutions are
x-3 =0
x = 3

Anyway, the image should be read first while this text explains the second part. Now you have the second equation, it can be factored down.
