Answer:

ΔPQR is not similar to ΔMRN.

Step-by-step explanation:

From the triangle PQR and MRN, Applying th basic proportionality theorem, we get

\frac{RM}{RP}=\frac{RN}{RQ}

Substituting the given values, we get

\frac{10}{18}=\frac{7}{21}

\frac{5}{9}{\neq}\frac{1}{3}

Therefore, the basic proportionality theorem does not hold, hence the given triangles PQR and MRN are not similar that is ΔPQR is not similar to ΔMRN.

Describe the error in the work shown. 62​ + 3 + 5 x 2 ​ ​ 36 + 8 x 2 ​36 + 16 52
makkiz [27]

Answer:

There is an error in the application of the DMAS rule, The answer as per the DMAS rule is 75.

Step-by-step explanation:

There is an error in the implication of the DMAS rule of Mathematics.

DMAS rule determines the arrangement of mathematical functions to be performed in an expression where multiple functions are present.

The DMAS Rules describes the following arrangement of the mathematical functions.

1st Division

2nd Multiplication

3rd Addition

4th Subtraction

Applying the above rule the solution is as follow

62​ + 3 + 5 x 2 ​ ​

First, we need to solve the Multiplication because there is no division

62​ + 3 + 10

Now perform the addition function

65 + 10

75

A line has a slope of –5 and a y-intercept of (0, 3). What is the equation of the line that is perpendicular to the first line a
neonofarm [45]
Slope-intercept form:
y=mx+b
m=slope
b=y-intercept

Data of the first line:
m=-5
b=y-intercept=3  (y-intercept=it is the value of "y" when x=0)

y=-5x+3

A line perpendicular to the line y=mx+b will have the following slope:
m`=-1/m

Therefore: the line perpendicular to the line y=-5x+3 will have the following slope:
m´=-1/(-5)=1/5

Point-slope form of a line: we need a point (x₀,y₀) and the slope (m):
y-y₀=m(x-x₀)

We know, the slope (m=1/5) and we have a point (3,2) therefore:
y-y₀=m(x-x₀)
y-2=1/5(x-3)     (point-slope form)
y-2=(1/5)x-3/5
y=(1/5)x-3/5+2
y=(1/5)x+7/5    (slope-intercept form)

Answer: the line perpendicular to the first line will be: y=(1/5)x+7/5
