Answer:

DE = 80.

Step-by-step explanation:

Since the 2 lines are congruent:

5x = 3x + 32

2x = 32

x = 16

So DE = 3(16) + 32

= 48 + 32

= 80.

Two angles of a triangle are the same size. The third angle is 12 degrees smaller than the first angle. Find the measure the ang

lesya692 [45]

Answer:12, 84 and 84

Step-by-step explanation:

since we know 3 angles of a triangle = 180 degrees

1 angle = 12 degrees

12 + x + x = 180

12 + 2x = 180

2x= 180 - 12

2x = 168

x = 168/2

x = 84 degrees

Mark and clean his father's office in 30 minutes his younger sister Lynn can clean the office in 40 minutes how long will it tak

egoroff_w [7]

we are given

Mark clean his father's office in 30 minutes

so, the amount of work done by Mark in 1 minute is $\frac{1}{30}$

younger sister Lynn can clean the office in 40 minutes

so, the amount of work done by younger sister Lynn in 1 minute is $\frac{1}{40}$

total work done by them in 1 minute is $\frac{1}{30}+\frac{1}{40}$

now, we can simplify it

$=\frac{4*1}{4*30}+\frac{3*1}{3*40}$

$=\frac{4+3}{120}$

$=\frac{7}{120}$

total time taken to complete same work is $\frac{120}{7} min$ ........Answer

Answer:

$\sqrt{2^5}$

Step-by-step explanation:

First, deal with the product of the two powers of 2 inside the parentheses.

The two factors are powers of 2, so add the exponents.

$(2^{\frac{1}{2}} \cdot 2^{\frac{3}{4}})^2 =$

$= (2^{\frac{1}{2} + \frac{3}{4}})^2$

You need a common denominator, 4, to add the fractions.

$= (2^{\frac{2}{4} + \frac{3}{4}})^2$

$= (2^{\frac{5}{4}})^2$

Now you have an exponent raised to an exponent. Multiply the exponents and reduce the fraction.

$= 2^{\frac{5}{4} \times 2}$

$= 2^{\frac{10}{4}}$

$= 2^{\frac{5}{2}}$

When a fraction is an exponent, the numerator is an exponent and the denominator is the index of the root. A denominator of 2 means a root index of 2 which means square root.

$= \sqrt{2^5}$

Find the distance between the two points G(-1,-5) and H(3,-8)

almond37 [142]

Answer:

5.099

Step by step explanations:

Input Data :

Point 1(xA,yA)(xA,yA) = (4, 3)

Point 2(xB,yB)(xB,yB) = (3, -2)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2

Solution :

Distance between two points = √(3−4)2+(−2−3)2(3-4)2+(-2-3)2

= √(−1)2+(−5)2(-1)2+(-5)2

= √1+251+25

= √2626 = 5.099

Distance between points (4, 3) and (3, -2) is 5.099
