Answer:
2 [tex]\frac{1}{20}[/tex]
Step-by-step explanation:
for question a)
It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)
to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.
E.g.
7 [tex]\frac{1}{4}[/tex] = 7x4 + 1 = 29
Thus, improper fraction would be [tex]\frac{29}{4}[/tex]
do same thing for other one
thus , [tex]\frac{26}{5}[/tex]
now,
[tex]\frac{29}{4}[/tex] - [tex]\frac{26}{5}[/tex]
however, you can't do this as the denominators are not the same, so multiply them by a number which would give the a common denominator (20 would be the best option for common denominator)
[tex]\frac{145}{20} -\frac{104}{20}[/tex] = [tex]\frac{41}{20}[/tex]
convert back to mixed number
2 [tex]\frac{1}{20}[/tex]
Answer:
Step-by-step explanation:
a) Step1 : write in improper form
Step 2 : Find least common denominator
Step 3: Find equivalent fractions and then subtract
[tex]7\frac{1}{4}-5\frac{1}{5} = \frac{29}{4}-\frac{26}{5}\\[/tex]
[tex]= \frac{29*5}{4*5}-\frac{26*4}{5*4}\\\\=\frac{145}{20}-\frac{104}{20}\\\\=\frac{145-104}{20}\\\\=\frac{41}{20}\\\\=2\frac{1}{20}[/tex]
b) Keep Change Flip method
[tex]4\frac{1}{4}[/tex] ÷ [tex]2\frac{1}{5} = \frac{17}{4}[/tex] ÷ [tex]\frac{11}{5}[/tex]
[tex]=\frac{17}{4}*\frac{5}{11}\\\\=\frac{85}{44}\\\\=1\frac{41}{44}[/tex]

Answer: x = 12, ∠B = 45°
Step-by-step explanation:
Angle A and Angle B are alternate exterior angles meaning that they are equal
5x - 15 = 2x + 21
3x - 15 = 21
3x = 36
x = 12
B = 2(12) + 21
B = 24 + 21
B = 45

Just trying to win the CONTEST BUT GOOOOD LUCK
Answer:
56 units, 84 units, 56 units, 140 units
Step-by-step explanation:
Since you have the ratios, you can multiply each by x, because you do not know the actual values.
2x+3x+2x+5x=336
12x=336
÷12 ÷12
x=28
Then, plug in the values of x.
So 2*28= 56
3*28=84
2*28=56
5*28=140

What is the equation of the line that passes through the point (4, -2) and has a
slope of -22
Answers
Answer: the answer is y=-22x+86
here is why:
the slope is -22 which is the m --> y=mx+b the point is (4,-2) the x=4 and y= =2
If we set up the equation:
-2= -22(4)+86
-2= -88+86
-2= -2

Complete the statements about the cone.
The height is units.
The radius is units.
The volume is Tot cubic units.
10
6
Answers
Answer:
The answers are:
The height is 6
The radius is 8
The volume is 128 π cubic units.
Step-by-step explanation:
The height is shown in the picture. So the first answer is 6.
To find the radius, you use the equation. [tex]\sqrt{slant height^{2}- height^{2} }[/tex] = radius
The slant height 10, and the height is 6. So you plug those into the equation and solve.
[tex]\sqrt{10^{2}-6^{2} }[/tex] =
[tex]\sqrt{100-36}[/tex] =
[tex]\sqrt{64}[/tex] = 8
So the radius is 8.
Now we use the equation [tex]\pi[/tex][tex]r^{2}[/tex] [tex]\frac{h}{3}[/tex] = volume.
[tex]\pi[/tex][tex]8^{2}[/tex] [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex]64 [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex] 64(2) = 128 [tex]\pi[/tex] cubic units
I hoped this helped you. I would love brainiest.
The statements about the cone is that,
The height is 6 units, the radius is 8 units and the volume is 128π cubic units.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given a cone.
We have to find the complete the statements related to the cone.
From the figure,
height of the cone = 6 units
Using the Pythagoras theorem,
Radius of the cone = √(10² - 6²) = 8 units
Volume of the cone = 1/3 π r² h
= 1/3 π × 8² × 6
= 128π cubic units
Hence the height, radius and volume of the cone are 6 units, 8 units and 128π cubic units respectively.
