express fractions below having equal denominators: a) 2/5, 7/10, 9/40. b) 17/25, 23/40, 67/120
Answer:
Step-by-step explanation:
a) 5 = 5
10 = 2 * 5
40 = 2 * 2 * 2 *5
Least common denominator = 2*2*2*5=40
Now find equal fractions with denominator 40
[tex]\frac{2}{5}=\frac{2*8}{5*8}=\frac{16}{40}\\\\\frac{7}{10}=\frac{7*4}{10*4}=\frac{28}{40}\\\\\frac{9}{40}[/tex]
Fractions with equal denominators:
[tex]\frac{16}{40} ; \frac{28}{40} ; \frac{9}{40}[/tex]
b) 25 = 5* 5
40 = 2 * 2 * 2 * 5
120 = 2 * 2 * 2 * 3 * 5
Least common denominator = 8*25*3=600
[tex]\frac{17}{25}=\frac{17*24}{25*24}=\frac{408}{600}\\\\\frac{23}{40}=\frac{23*15}{40*15}=\frac{345}{600}\\\\\frac{67}{120}=\frac{67*5}{120*5}=\frac{335}{600}\\\\[/tex]
Solve for X:
-7x + 15 > -20
Answer:
14
Step-by-step explanation:
because when you solve the equation you subract 15 from both sides and then divide -7 from the answer
Answer:
x < 5
Step-by-step explanation:
-7x + 15 > -20Step 1 :- Move constant to the right-hand side and change their sign.
-7x > -20 -15Step 2 :- Calculate the difference.
-7x > -35Step 3 :- Divide both side of the inequality by -7 and flip the inequality sign.
-7x / x < -35 / 7x < 535 POINTS. PLS HELP
What is the approximate volume of the composite figure? Use 22/7 for pi. Round to the nearest hundredth. Enter your answer in the box.
Answer:
188.57 cm³
Step-by-step explanation:
Half sphere = 1/2 volume sphere
Sphere = 4/3 * 22/7 * 3³
Sphere = 4/3 * 22/7 * 27/1
Sphere = 2376/21 = 113.14
113.14 / 2 = 56.57
Cone = 22/7 * 3² * h/3
Cone = 22/7 * 9/1 * 14/3
Cone = 2772/21 = 132
132 + 56.57 = 188.57 cm³

Round this value however you need to.
=====================================================
Explanation:
The given set of values is {11, 86, 46}
Add up the numbers to get 11+86+46 = 143
Then divide by 3 to get 143/3 = 47.667 approximately. We divided by 3 because there are 3 values in the given set.
Okey hey, hi, hello, all I want to know is how to put this dang thing on the number line but I have searched everywhere and no one can help me !!!!!!!!
Can you ?
Your graph would be correct if the given equation was |x| = 5
This is because |x| describes the distance x is from zero, and asking |x| = 5 means we want to find which values are 5 units away from zero: those two values being 5 and -5.
--------------
However, your teacher gave you instead |x| = -5. The distance cannot be negative, so |x| is never negative. Therefore, |x| = -5 has no solutions
The graph will simply be an empty number line with no points plotted on it.

Which of the following represents an image of △LMN under a dilation with a scale factor of 14/?
HELP ME NOW!! RED IS THE ONE I GOT WRONG!
Answer:
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
Dilation is the increase or decrease in size of a figure by a factor k. If k > 1, then the dilation is an increase whereas if k<1, then the dilation is a decrease.
From the diagram, since triangle LMN is dilated by a factor of 1/4, hence the size of LMN is reduce. Therefore:
L'M' = (1/4)LM, L'N' = (1/4)LN, N'M' = (1/4)NM
Also, the distance from point P to N' is one-fourth of the distance from point P to N.
The correct option is highlighted in the image attached.
-4.3 + x equals 0 selected place on the number line to positive value of x
Answer:
x is equal to 4.3
Step-by-step explanation:
since it's -4.3 + x is equal to 0
you take -4.3 to the other side of the equal sign which makes it positive and x is equal to 4.3

Calculate the following
S2+54+18+46+237
Note that you can make the work very easy by being smart in deciding how to
group the operations
Answer:
S2 + 355
Step-by-step explanation:
Given the expression to evaluate :
S2+54+18+46+237
Since the values are bound by the addition operator, we take the sum of the like terms ;
S2 + (54+18+46+237)
S2 + 355

new community center. How I Find the prime factorization of the number 24
Answer:
2*2*2*3
or
2^3 * 3
Step-by-step explanation:
24 = 4*6
But 4 and 6 aren't prime
24 = 4*6 = (2*2) * (2*3)
All these numbers are prime
24 = 2*2*2*3 or with exponents = 2^3 * 3
Erin calculated the average speed of her most recent run to be 120/16 miles per hour how is this friction expressed as a decimal
Answer:
[tex]\dfrac{15}{2}[/tex]
Step-by-step explanation:
The average speed of the Erin is 120/16 mph
Here,
Numerator = 120
Denominator = 16
mph = miles per hour
We need to find an expression expressed as a decimal.
So,
[tex]\dfrac{120}{16}=\dfrac{2\times 3\times 2\times 2\times 5}{2\times 2\times 2\times 2}\\\\=\dfrac{15}{2}[/tex]
So, the final answer is [tex]\dfrac{15}{2}[/tex].

Solve the equation -3h + 6 = -15 for h.
Answer:
h = 7
Step-by-step explanation:
-3h + 6 = -15
Get rid of the 6 by subtracting it from both sides.
-3h + 6 - 6 = -15 - 6
-3h = -21
Get rid of the -3 by dividing it from both sides.
-3h/-3 = -21/-3
h = 7
