Answer:

100

Step-by-step explanation:

Ok I will sub!

Answer:

Neither.

Step-by-step explanation:

    Parallel lines have equivalent slopes while perpendicular lines have opposite reciprocal slopes. (Opposite meaning different signs and reciprocal meaning flipped fraction)

[tex]wx:~m=\frac{4-3}{6-(-3)}\\wx:~m=\frac{1}{9}\\\\yz:~m=\frac{-6-(-4)}{8-6}\\yz:~m=\frac{-2}{2}\\yz:~m=-1[/tex]

These lines are neither parallel nor perpendicular.

Answer:

equation: a/.5b=h

h=9

Step-by-step explanation:

a=1/2bh

divide both sides by 1/2b to get h alone

a/.5b=h

a/.5b=h

54/0.5(12)=h

54/6=h

9=h

Answer:

D. y = 4x - 6

Step-by-step explanation:

The equation that is perpendicular to the line MN should have a slope that when multiplied by the slope of line MN will result to negative one. Therefore,

Therefore,

m₁ × m₂ = -1

Using the 2 coordinates of MN let's find the slope,

(-7, 6)(5, 3)

Therefore,

m₁ = 3 - 6 / 5 - (-7) = -3 / 12 = - 1 / 4

The equation that represent a line perpendicular to the line MN is

y = 4x - 6 because the slope slope(m₂) is 4.

From our formula,

4 × - 1 / 4 = - 1

So, option D meets the requirement.

Answer:

D. y = 4x - 6

Step-by-step explanation:

Answer:

sqrt(x) where x is between 81 and 100; example sqrt(88). See explanation for more examples.

Step-by-step explanation:

9=sqrt(81) and 10=sqrt(100)...

So the square root(x) is between 9 and 10 if x is between 81 and 100.

Here are examples:

sqrt(82)

sqrt(83)

sqrt(85.6)

sqrt(92)

sqrt(94)

sqrt(97)

sqrt(99)

sqrt(99.6)

So again the answer is just anything in form sqrt(x) where x is between 81 and 100. The reasoning is because sqrt(81)=9 and sqrt(100)=10 which puts the values we stated between those values.

Lidal : 9 rolls for £3.51

1 roll for 3.51/9 = £0.39

Oldi : 4 rolls for £1.52

1 roll for 1.52/4 = £0.38

so, Oldi has the best value for money when buying toilet rolls.

Answer:

the slope=-1 the slope perp=1

Step-by-step explanation:

to find slope perpendicular you just have to multiply your slope by something and have it equal -1

for example

1/2x=-1

the slope perpendicular to a line with the slope of 1/2 would be -2 beacause 1/2x-2=-1

so the slope x perpendicular slope = -1

Answer:

30%

Step-by-step explanation:

total boxes of pizza = 20

he gave away 14 boxes

so pizza left is 20 - 14 = 6 boxes

to calculate percentage = 6 / 20 * 100

= 6 * 5

= 30%

Answer:

5

Step-by-step explanation:

q = 6

r = 19

4q^2

= 4 x q^2

= 4 x 6^2

= 4 x 6 x 6

= 144

qr

= q x r

= 6 x 19

= 114

qr + 25

= 114 + 25

= 139

4q^2 - ( qr + 25 )

= 144 - 139

= 5

Answer:

i think 15 if thats on your answer sheet

Step-by-step explanation:

Given, consecutive / adjacent angles in a parallelogram are supplementary or make 180°. So, here (5a + 34)° & (3a + 26)° are supplementary angles.

=》5a + 34 + 3a + 26 = 180

=》5a + 3a + 34 + 26 = 180

=》8a + 60 = 180

=》8a = 120

=》a = 120/8

=》 a = 15

Answer:

see explanation

Step-by-step explanation:

Given

cotθ = [tex]\frac{4}{5}[/tex] = [tex]\frac{adjacent}{opposite}[/tex]

Use Pythagoras' identity to calculate the hypotenuse h

h² = 4² + 5² = 16 + 25 = 41 ( take square root of both sides )

h = [tex]\sqrt{41}[/tex]

θ is in quadrant III where sinθ < 0 and secθ < 0

sinθ = [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{5}{\sqrt{41} }[/tex] = -  [tex]\frac{5\sqrt{41} }{41}[/tex]

cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = - [tex]\frac{4}{\sqrt{41} }[/tex]

secθ = [tex]\frac{1}{cos0}[/tex] = - [tex]\frac{\sqrt{41} }{4}[/tex]

Answer:

D- Recording the reaction time of participants in a study who were asked to press a button as soon as they see a certain picture on a screen.

Step-by-step explanation:

The situation is an example of an observational study is "Recording the reaction time of participants in a study who were asked to press a button as soon as they see a certain picture on a screen:.

When researchers monitor the effect of a risk factor, diagnostic test, therapy, or other intervention without attempting to influence who is or is not exposed to it in observational studies.

For example: Consider someone standing on a popular street in a New York neighborhood asking passers-by how many dogs they have, then analyzing the data to see if more pet food businesses are needed in the area.

As we know that in an observational study, the sample whose test/survey is been taken is completely random.

Therefore, the situation that is an example of an observational study is " Having customers fill out a questionnaire about their favorite brand of toothpaste".

Answer:

step 3

Step-by-step explanation:

when you multiply an even amount of negative numbers you will always get a positive result thus the answe would be 16.6 + 4.15 as in positive numbers

Answer:

let h(t)= 0 (because when it reaches the ground h=0)

0=-16t^2+116

16t^2=116

divide both sides by 16

t^2= 7.25

square root both sides to find t

t=2.69sec
