Step-by-step explanation:

Just subtract the functions

Answer:

Undercast refers to a forecasting error when estimated numbers turn out to be lower than realized numbers. The estimates that are valued can include sales, expenses, income, cash flows, or any other financial account or metric.

[tex]\\ \rm\longmapsto \overline{z}=-\sqrt{3}-2[/tex]

Answer: 3/20

Concept:

When encountering questions that ask for [how much longer A comparing to B], the basic operation would be the value of A subtracted by the value of B.

Solve:

Given information

Maggie study time = 2/5 hours

Julie study time = 1/4 hours

Given expression deducted from the concept

Maggie (study time) - Julie (study time)

Substitute values into the expression

2/5 - 1/4

Find the denominators' Least Common Multiple (LCM)

First five multiples of 5: 5, 10, 15, 20, 25

First five multiples of 4: 4, 8, 12, 16, 20

Since [20] is the first term that appears in both multiples, it would be the LCM of 4 and 5

Convert the fractions to common denominator

2/5 = (2 × 4) / (5 × 4) = 8 / 20

1/4 = (1 × 5) / (4 × 5) = 5 / 20

Simplify by subtraction

=8/20 - 5/20

=(8 - 5) / 20

Answer:

(-1,1)

Step-by-step explanation:

First split it into 2 functions, when x≥0 let f1(x)=x1+x and when x<0 let f2(x)=x1−x now we have 2 functions that are continuous on their domains.

Step-by-step explanation:

1. 20

2. 100

3. 25

4. 45

5. 50

Answer:

opt. 2

Step-by-step explanation:

take (4,0) as solution

0= -1/2(4)+2

  = -2+2 = 0

let "L" represent the length of the rectangle

let "W" represent the width of the rectangle

Area of the rectangle = LW

68= LW --------eqn 1

Area of a square = L/2 ×L/2

34= L^2/4

136=L^2

L= 11.67

From eqn 1 , W=68/L

W=68/11.6619

W=5.83

Answer:

2300

Step-by-step explanation:

when rounding 2259 to the nearest hundred look at the digit in the tens place, if the number is 5 or higher, you round up to 2300, if its 4 or less, you round down to 2200. hope this helps!

Answer:

X=67°,Z=113°,Y=0°

Step-by-step explanation:

2.1=

X+113°=180°(being straight angle)

Or, X=180°-113°

Or,X=67° answer

Now,

Z=113°(being alternative angle)

Again,Y+Z+X=180°(being co-interior angle)

Or, Y+113°+67°=180°

Or,Y+180°=180°

Or,Y=180°-180°

=Y=0° answer

x + 8 = 15

Subtracting 8 from both sides,

x = 15 - 8

=> x = 7

Answer:

[tex]3( \frac{7}{5}x + 4) - 2( \frac{3}{2} - \frac{5}{4} x) \\ \\ \frac{21}{5} x + 12 - 3 + \frac{5}{2} x \\ \frac{21}{5} x + \frac{5}{2} x + 9 \\ \frac{67}{10}x + 9[/tex]

Answer:

The easiest approach is to realise that one hour is 3 times longer than 20 minutes. The longer the time, the more they will pave.

215 of a mile, in 20 minutes, how much in 60 minutes?#

They will pave 3 times more.

215×31=615 of a mile

615=25 of a mile

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by 20) and them multiply by 60 to find how much in one hour.

Look at what happens:

215÷20×60

=215×120×603

=215×3 ← exactly the same maths.

=25
