Answer:
[tex] \frac{a}{b} = 1.5 [/tex]
Step-by-step explanation:
Given that both ∆s are similar, therefore the ratio of their corresponding sides will be the same.
This means: [tex] \frac{2.1}{a} = \frac{1.4}{b} [/tex].
Since this equation is true, rewrite so that you have [tex] \frac{a}{b} [/tex]
[tex] \frac{2.1}{a} = \frac{1.4}{b} [/tex]
Cross multiply
[tex] a*1.4 = b*2.1 [/tex]
Divide both sides by 1.4
[tex] a = \frac{b*2.1}{1.4} [/tex]
Divide both sides by b
[tex] \frac{a}{b} = \frac{2.1}{1.4} [/tex]
[tex] \frac{a}{b} = 1.5 [/tex]
The value of [tex]\dfrac{a}{b}[/tex] is [tex]1.5[/tex].
Given:
Two triangles in the given figure are similar.
To find:
The value of [tex]\dfrac{a}{b}[/tex].
Explanation:
The corresponding sides of two similar triangles are proportional.
[tex]\dfrac{a}{2.1}=\dfrac{b}{1.4}[/tex]
It can be rewritten as:
[tex]\dfrac{a}{b}=\dfrac{2.1}{1.4}[/tex]
[tex]\dfrac{a}{b}=1.5[/tex]
Therefore, the value of [tex]\dfrac{a}{b}[/tex] is [tex]1.5[/tex].

Meandre has 8 pints of milk. If he drinks ¼ of a pint of milk each day, how long will the 8 pints of milk last him?
Answers
Answer:
16 days
Step-by-step explanation:
1/4 = 0.25
8 divied 32
In multiplacation
8 time 4 = 32
8 pints of milk will last for 32 days.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
Given that,
Total amount of milk Meandre has = 8 pints
Amount of milk drinking in 1 day = 1/4 pint
We have to calculate the number of days that 8 pints of milk will last.
Let x be the required number of days.
Using the concept of proportion,
(1/4) / 1 = 8 / x
1/4 = 8 / x
x = 8 × 4
x = 32
Hence total number of days that 8 pints of milk will last is 32 days.

Step-by-step explanation:
First you would do (6+9) because it's in parenthesis. (6+9)= 15. So now our equation looks like 15+4=4+? Next we will do 15+4=19. 19=4+? is the new equation. Now the final step is to do 19-4=15 which is what we will plug into the equation.

(24)^3=13,824
when you multiply 4^3 with 6^3 you get the same answer of 13,824
Answer:
Answer=D
Step-by-step explanation:
(for powers outside a bracket it splits in the numbers inside the bracket)
(4×6)^3
=([tex]4^{3}[/tex]×[tex]6^{3}[/tex]) as in D
To proof
-if we multiply them first we will get 24 and that to the power of three will equal to 13824.
-if we did as in the answer so,
[tex]4^{3}[/tex]×[tex]6^{3}[/tex]
=64×216
=13824
they are equal to each other 13824=13824 so answer D is correct.

C is the circumcenter of PQR
PC=3x+7, RC=5x-15 and QC=51-x.
what does RC equal?
Answers
Answer:
[tex] RC = 40 [/tex]
Step-by-step explanation:
Given:
PC = 3x + 7,
RC = 5x - 15,
QC = 51 - x.
Required:
measure of RC
SOLUTION:
Given that C is the circumcenter of ∆PQR, therefore, vertices P, Q, and R are equidistant from C.
So therefore,
[tex] PC = RC = QC [/tex]
Let's find the value of x using:
[tex] PC = RC [/tex]
[tex] 3x + 7 = 5x - 15 [/tex] (substitution)
Collect like terms
[tex] 3x - 5x = -7 - 15 [/tex]
[tex] -2x = -22 [/tex]
Divide both sides by -2
[tex] x = \frac{-22}{-2} [/tex]
[tex] x = 11 [/tex]
Find the measure of RC
[tex] RC = 5x - 15 [/tex]
substitute x = 11 into the equation
[tex] RC = 5(11) - 15 [/tex]
[tex] RC = 55 - 15 [/tex]
[tex] RC = 40 [/tex]
