Step-by-step explanation:

Little tip my teacher taught me in 5th or 6th grade ,look at which way the arrow is pointing and compare it to an inequality symbol (imagine the inequality symbol as the arrow).

In this case the arrow is pointing right , so which inequality symbol looks most like it?

Obviouslyy,the less than sign!

Also! , an closed circle means "or equal to" which is the line under the inequality symbol.

And an open circle basically means just the inequality symbol.

Answer:

-11

Step-by-step explanation:

3 x (-3) x 2 - 4 x (-3) - 5

= -18 + 12 - 5

= -11

Answer:

Step-by-step explanation:

f(x)=f(5) which means 5=x so if 5=x then we can put it into the equation of     3(x-2)

3(5-2)

Hope that helps :)

Answer:

well x = -8 so

Let's solve your equation step-by-step.

6(x−1)=9(x+2)

(6)(x)+(6)(−1)=(9)(x)+(9)(2)

6x+−6=9x+18

6x−6=9x+18

step two

6x−6−9x=9x+18−9x

−3x−6=18

step three

−3x−6+6=18+6

−3x=24

last step

−3x /−3 = -24 /−3

x=−8

Step-by-step explanation:

The answer is 35.1 cm².

Hope this helps; have a great day!

Question:-

Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.

_______________________________________________

Solution:-

In an equilateral triangle all sides are equal.

Let s = side length = 9 cm

Then, area of equilateral triangle is given as:

A = (√3/4)s²

Putting the value of s here,

A = (√3/4) * (9 cm)²

=> A = (√3/4) * 81 cm²

=> A = √3 * 20.25 cm²

We know that, √3 = 1.732

=> A = 1.732 * 20.25 cm²

=> A = 35.073 cm²

Rounding to one decimal place,

=> A = 35.1 cm²

Answer:

1) 1    2) 3   3) 5  4)7

Step-by-step explanation:

In the question it gives you the formula 2n-1

n= number or term for example 1

2x1-1=1

205 liters in 5 1/4 minutes

m = 5 1/4

20 (5 1/4) = 105

100+105= 205

Answer and Step-by-step explanation:

m_| 2(3m + 7) |_6m + 14_|

1    |      20       |       20     |

2   |      26       |       26     |

This table can be used to show that the expression are equivalent because every time the variable was plugged in, the output was the same for both equations.

Also, the first equation is the undistributed version of the second equation.

Answer:

1350 bajan dollar

Step-by-step explanation:

The exchange rate of EC dollar to Barbados currency is

1 EC dollar = 0.75 Barbados currency

EC $1800 in Barbados currency = EC $1800 x 0.75 = 1350 bajan dollar

Answer:

B

Step-by-step explanation:

They both equal 121

Answer:

A. The number of boxes that can be packed by Ryan and Daniel each increases over time. Daniel's function has a greater rate of

change than Ryan's function indicating that Daniel can pack more boxes per hour.

Step-by-step explanation:

Given

Ryan: 3 boxes per hour

Daniel: [tex]y = 4h[/tex]

Required

True statement about their functions

First, we calculate Ryan's function.

In 1 hour, he can pack 3 boxes.

In hours, he can pack 3h boxes.

So, the equation is:

[tex]y = 3h[/tex]

So, we have:

[tex]y = 3h[/tex] ---- Ryan

[tex]y = 4h[/tex] --- Daniel

Both functions represent direct proportional functions.

So, when h increases y also increases.

However, Daniel's function has a greater rate of change because[tex]y = 4h[/tex] implies that he can pack 4 boxes per hour while Ryan can pack 3.

Answer:

y=1/2x+7

Step-by-step explanation:

First find the slope of the function

Use slope formula:

10-9/6-4 =1/2

M= 1/2x

Find y-intercept:

9=1/2(4)+b

B=7

Answer:

4x+3y=134

3x+3y=120

Step-by-step explanation:

x represents boxes of black-and-white brochures, while y represents boxes of color brochures.

4x + 3y = 134

3x + 3y = 120

Step-by-step explanation:

Answer:

10.5618feet, 0.8125sec

Step-by-step explanation:

Given the height reached by the catapult expressed by the equation H=-16T^2+26T

At the maximum height, the velocity of the object is zero, hence;

v = dh/dt = 0

-32t + 26 = 0

-32t = -26

t = 26/32

t = 0.8125secs

Hence it will attain the maximum height after 0.8125second

Substitute t = 0.8125s into the expression to get the maximum height

H=-16t^2+26t

H = -16(0.8125)^2 + 26(0.8125)

H = -16(0.6602) + 21.125

H = -10.5632+21.125

H = 10.5618

hence the maximum height reached by the ball is 10.5618feet

Let R = reference angle in quadrant 2.

R = 180° - given angle.

R = 180° - 60°

R = 120°

Answer:

cosH = JH/KH

Step-by-step explanation:

coa refers to base by hypotenuse

for H,

the base is JH and the hypotenuse is KH.

In the given right angled triangle cos H is equivalent to sin K

A triangle in which one of the interior angles is 90° is called a right triangle

Here,

Cos H =  Adjacent side / Hypotenuse = [tex]\frac{JH}{KH}[/tex]

In the given option

sin K = Opposite side / Hypotenuse[tex]=\frac{JH}{KH}[/tex]

Therefore Cos H is equivalent to the sin K

Hence, sin K is equivalent to the cos H

Answer:

4.7m

Step-by-step explanation:

the length of longest iron rod which can be placed flat across the diagonal of the garden shed can be determined using the Pythagoras theorem,

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = diagonal

4² + 2.5² = 22.25²

c =√22,25 = 4.7m
