a. 5 5/6
b. 5 1/6
c. 5 2/3
d. 5 7/6
Answer:
[tex]A.5^{\frac{5}{6}}[/tex]
Step-by-step explanation:
[tex]We\ are\ given:\\(\sqrt{5})(\sqrt[3]{5})\\To\ simplify\ the\ given\ expression\ we\ may\ use\ the\ following\ two\\ 'Laws\ Of\ Exponents'.\\1.\sqrt[n]{a}=a^{\frac{1}{n}}\\2.m^a*m^b=m^{(a+b)}\\With\ these\ two\ equations\ we\ can\ proceed\ with\ our\ problem:\\Hence\ following\ Law\ 1,\\\sqrt{5}=5^{\frac{1}{2}} \\\sqrt[3]{5}=5^{\frac{1}{3}}\\Hence,\\\sqrt{5}*\sqrt[3]{5}=5^{\frac{1}{2}}* 5^{\frac{1}{3}}\\Hence,\\5^{\frac{1}{2}}* 5^{\frac{1}{3}}\\Now,\ by\ using\ Law\ 2,\\[/tex]
[tex]5^{(\frac{1}{2}+\frac{1}{3})}\\=5^{(\frac{3+2}{6})}\\=5^{\frac{5}{6}}\\[/tex]

Emma is 10 years old. She asked her father how old he was. Her father answered: "When you will be my age, I will be 70." How old is Emma's father?
Answer:
Emmas father would be 40 years old
Step-by-step explanation:
if the father is 40 years old right now emma will be his age in 30 years.
in 30 years emma will be as old as he was when she was ten (10+30=40)
after the 30 years emmas father who was once 40 years when she asked how old he was would be 70 years old (30+40=70)
He is 40 years old.
Equation: (f+e)/2 = father's age. Here f=70 and e=10.
So, (70+10)/2 = 80/2 = 40.
Solution can be wrong. But answer is right. Answer is definitely 40 years old
Micah who is not yet 15 years old, is two years older than DeMonte.
How old is DeMonte?
x = the age of Micah
y = the age of DeMonte
Answer:
DeMonte is 12
Step-by-step explanation:
If Micah is not yet 15 than he is 14 so 14 - 2 is 12 since DeMonte is two years younger than Micah.
At 8:00, the temperature was 15 degrees Celsius (°C). Three hours later, the temperature was -15°C. By how many degrees Celsius did the temperature change?
Answer:
30 degrees
Step-by-step explanation:
If you were to draw a number line, 15 and -15 are both 15 units away from 0. So, 15 + 15 =30

Also,How do I factorise these?
x²-49
x²-9
x²-16
Answer:
Step-by-step explanation:
x2 - 49
Both are squares so
Square root (x2) - Square root (49)
= x - 7
The other two answers are x - 3 and x - 4
Answer:
Use the formula (x-a)(x+a)=x^2 - a^2
so what is the square root of 49, 9, and 16? By finding the square root you get a, and you can just plug it into the formula. For example the first one, 7 is the square root of 49. So, (x-7)(x+7)

Answer:
IT's -3.6 & 14.4 so D is the correct answer
Step-by-step explanation:
x= -3.6 y= 14.4
HOW I SOLVED IT
-3.6 x 3 = -10.8 2 x 14.4 = 28.8 - 10.8 = 18 so correct since it must equal to 18
-2/3 x -3.6 =2.4 + 12 = 14.4 so correct since y = 14.4

Find the slope of the line that passes through (8,6) and (4,15)
two supplementary angles are in a ratio of 7:11. find the measures of each angle
Answer:
70° and 110°
Step-by-step explanation:
Supplementary angles sum to 180°
sum the parts of the ratio, 7 + 11 = 18 parts
Divide 180° by 18 to find the value of one part of the ratio.
180° ÷ 18 = 10° ← value of 1 part, thus
7 parts = 7 × 10° = 70°
11 parts = 11 × 10° = 110°
The 2 angles are 70° and 110°

A company makes spherical tanks that store chemicals. Their standard model has a diameter of 6 meters, but a customer needs a larger tank whose capacity is 2.5 times the volume of the standard model. What is the approximate diameter of this larger tank? Round to the nearest tenth.
Answer:
The approximate diameter of the larger tank is 8.10 meters
Step-by-step explanation:
Here, we want to calculate the diameter of the larger tank
The volume of a sphere
V = 4/3 * π * r^3
Let us calculate the volume of the standard model
That will be;
Since diameter is 6 and r = d/2
r = 6/2 = 3 meters
V = 4/3 * π * 3^3 = 36 π m^3
Now, the volume of the larger tank is 2.5 times of this;
The volume of the larger tank is 2.5 * 36 π = 90 π m^3
So we can calculate the radius of this before we calculate its diameter
4/3 * π * r^3 = 90 π
4r^3/3 = 90
r^3 = 270/4
r^3 = 67.5
r = 3x√(67.5)
r = 4.07 m
Diameter here is 2 times this
= 4.07 * 2 = 8.14
Answer:
8.1

Here is a list of numbers:
6, 16, 6, 18, 16, 3, 8 ,9 ,6
State the median.
Answer:
8
Step-by-step explanation:
You have to list the numbers in the correct order then fond the one that falls in the middle, if there are 2 numbers that fall in the middle, then you add those 2 then divide by 2.
Hope it helps! Merry Christmas!
Answer:
8
Step-by-step explanation:
Arrange the set of numbers from least to greatest:
3,6,6,6,8,9,16,16,18
Start from both ends and cross them off until you're left with just one.
6,6,6,8,9,16,16
6,6,8,9,16
6,8,9
8
The median is 8 because that's what you're left with.

6. The measures of two angles are (4x + 19) and (7x -29)°. What is the value of x if
these angles are congruent?
Answer:
The value of x is 16
Step-by-step explanation:
Given two angles are:
(4x + 19) and (7x -29)°
Two angles being congruent means that their numerical values will be equal
Putting both expressions equal
[tex]4x+19 = 7x-29[/tex]
Subtracting 7x from both sides
[tex]4x+19-7x = 7x-29-7x\\-3x+19 = -29[/tex]
subtracting 19 from both sides
[tex]-3x+19-19 = -29-19\\-3x = -48[/tex]
Dividing both sides by -3
[tex]\frac{-3x}{-3} = \frac{-48}{-3}\\x = 16[/tex]
Hence,
The value of x is 16
Some pencils are to be shared between Grade 7, Grade 8 and Grade 9 students in the
ratio 3:5:6 respectively. If Grade 8 students receive 196 more than Grade 7 students, find
the total number of pencils shared.
Answer:
1312
Step-by-step explanation:
if grade 8 has 196 more, that means 196 represents two cause 5 is 2 more than 3, so then you divide 196 in half to get 98, then add 196 and 98, so grade 7 gets 294 pencils, the to find how many for grade 8 you take 294 plus 196 and get 460 so grade 8 gets 460, and for grade 9 you add 460 and 98 to get 558, then just add, 294, 460, and 558 and you get 1312. hope this helps

Since you know a line is = 180*
if angle EFG is 125, we can get angle EFD = to 180-125=55
And since we know that the line ED is congruent to line EF, angle EDF is = 55
180-55*2= 70
angle DEF=70
A certain drug is made from only two ingredients: compound A and compound B. There are 5 milliliters of compound A used for every 4 milliliters of compound
B. If a chemist wants to make 621 milliliters of the drug, how many milliliters of compound A are needed?
Answer:
884
Step-by-step explanation:
We know the ratio of A to B is 5:8
let x = the multiplier
then
5x = amt of compound A
and
8x = amt of compound B
:
5x + 8x = 884
13x = 884
x = 884/13
x = 68 is the multiplier
therefore
5(68) = 340 millilters of compound A needed
:
:
Confirm our answer. Find the amt of B
8(68) = 544 ml of B
340 + 544 = 884
