Answer:
The majority of theorems in mathematics take the form of compound statements. These statements are called conditional and biconditional statements.
The conditional statement from the sentence above is:
If x is an engineer then x is resourceful.
Put in a mathematical form we can refer to the Implication as:
If Xe then R. Or
Xe implies R. Or
Xe if R.
The Hypothesis is stated as
Xe ⇒ R
The statement Xe in an implication Xe ⇒ R is called its hypothesis, premise, or antecedent, and R the conclusion or consequence.
Implications are critical in expressing a logical argument. If an implication is found to be true, then the consequences must be as well when the hypothesis satisfied. This is why is also referred to as a conditional statement.

The length of the subway is 900 miles.If 1 inch represents 45 miles ,what is the length of the subway on the map
Answer:
Step-by-step explanation:
The length of the subway is 900 miles.
So if 1 inch is 45....we want to find it for 900 miles
900/45 = 20
So it will be 20 inches for 900 miles
Check by using ratio
1 : 45
2 : 90
3 : 135
4 : 180
5 : 225
6 : 270
7 : 315
8 : 360
9 : 405
10 : 450
11 : 495
12 : 540
13 : 585
14 : 630
15 : 675
16 : 720
17 : 765
18 : 810
19 : 855
20 : 900
1 - 20 = inches
45 - 900 = miles
So for 900 miles, it will be 20 inches long

Akira and Hideo are twins with different jobs. Akira earns five-eighths of what Hideo earns, but Akira’s expenses are half of Hideo’s. Akira ends up saving 40% of his income. What percentage of his income does Hideo save?
9514 1404 393
Answer:
25%
Step-by-step explanation:
Apparently, we're to assume that anything not spent is saved.
Let Hideo's income be 1. Then Akira's income is 5/8. Akira's expenses are 60% = 3/5 of that value, so ...
Akira's expenses = (3/5)(5/8) = 3/8 . . . . . of Hideo's income
Hideo's expenses are twice this amount, so ...
Hideo's expenses = (2)(3/8) = 3/4 . . . . . of Hideo's income
That means Hideo saves 1 -3/4 = 1/4 = 25/100 = 25% of his income.
Hideo saves 25% of his income.
Immediate help ASAP whats the value of f(8)
Answer:
[tex] \large \boxed{f(8) = 27}[/tex]
Step-by-step explanation:
Goal
Find f(8)Given
Equation[tex]f(x) = \frac{1}{2} {x}^{2} - ( \frac{1}{4} x + 3)[/tex]
Step 1
Substitute x = 8 in the equation and replace f(x) with f(8).[tex]f(8) = \frac{1}{2} {(8)}^{2} - ( \frac{1}{4} (8) + 3)[/tex]
Step 2
Evaluate the value of f(8).[tex]f(8) = \frac{1}{2} (64) - ( \frac{8}{4} + 3) \\ f(8) = 32 - ( \frac{2}{1} + 3) \\ f(8) = 32 - (2 + 3) \\ f(8) = 32 - (5) \longrightarrow 32 - 5 \\ f(8) = 27[/tex]
Hence, the value of f(8) is 27.

Answer:
True
Step-by-step explanation:
Cuz if u substitute (3,-3/2) it would work
Y = 1/2x - 3
-3/2 = 1/2(3)-3
-3/2 = 1.5 - 3
-3/2 = -1.5
& -3/2 is -1.5 as a decimal lol

Step-by-step explanation:
The price of all rail tickets increased by 5 %.
The price of a rail ticket from London to Ipswich increased by £2.30
Work out the price of the ticket before the increase.
Answer:
Step-by-step explanation:
New price = (1 + 5%) x old price
New price = 1.05 x old price
old price = 2.3 / 1.05
Old price = £2.19
9514 1404 393
Answer:
£46
Step-by-step explanation:
The increase is ...
0.05 · price = £2.30
Multiplying by 20 gives ...
price = 20(£2.30) = £46.00
The price of the ticket before the increase was £46.00.

if you divide both by 6
So y = 10
x=10 and y=10 is it intercepting parallel or same line?
Answer:
Parallel lines have the same slope. Because the functions \displaystyle f\left(x\right)=2x+3f(x)=2x+3 and \displaystyle j\left(x\right)=2x - 6j(x)=2x−6 each have a slope of 2, they represent parallel lines. Perpendicular lines have negative reciprocal slopes. Because −2 and \displaystyle \frac{1}{2}
2
1
are negative reciprocals, the equations, \displaystyle g\left(x\right)=\frac{1}{2}x - 4g(x)=
2
1
x−4 and \displaystyle h\left(x\right)=-2x+2h(x)=−2x+2 represent perpendicular lines.
Answer:
Intercepting.
Step-by-step explanation:
The line x=10 is a straight vertical line going through all the points where x=10, as the equation suggests.
The line y=10 is a horizontal line going through all the points where y=10.
When you graph them, they intersect in a perfect cross.
8x+6 factorise fully
Answer:
2(4x+3)
Step-by-step explanation:
We need to find what is the most common between 8x and 6. The only number here is 2 that is common between them.
That will be on the outside of the bracket.
So if we divide 2 from both terms.
8x ÷ 2 = 4x
6 ÷ 2 = 3
Let's put it all together.
2 first.
Our x term and 3 in brackets.
2 (4x+3)

Explain the prices of dividing two fractions
Answer:
When dividing two fractions, the process is very easy. You simply multiply the numerator fraction by the reciprocal of the denominator fraction. In other words:
[tex]\frac{a}{b} \div \frac{c}{d} \\= \frac{a}{b} \times \frac{d}{c} \\= \frac{a \times d}{b \times c}[/tex]

Jamal drives 3 times the hours that Danielle does. Jamal and Danielle drive for a total of 8 hours. How long did each person drive?
Answer: Danielle drive for 2 hours
Jamal drives for 2 × 3 = 6 hours
Step-by-step explanation:
Let the number of hours that Danielle used in driving to be represented by x.
Since Jamal drives 3 times the hours that Danielle does. This will be:
= 3 × x = 3x
Since Jamal and Danielle drive for a total of 8 hours. This can be formed into a equation as:
x + 3x = 8
4x = 8
x = 8/4
x = 2
Danielle drive for 2 hours
Jamal drives for 2 × 3 = 6 hours
solve: (3-x)(4x+3)<(2x-1)(3-x)

Evaluate the function at the given values.
f(x) = 6x - 4
a. f(9)
b.10-
c. f)
a. f(9)
Answer:
f(9) = 50
f(-10) = -64
Step-by-step explanation:
Given the function
f(x) = 6x - 4
f(9) = 6(9)-4
f(9) = 54-4
f(9) = 50
b)f(-10)
f(-10) = 6(-10) - 4
f(-10) = -60 -4
f(-10) = -64
A mermaid has a terrarium that measures 42 inches × 10 inches × 9 inches. She also has a box that measures 3 inches × 3 inches × 3 inches. Every minute, the mermaid fills the box with sand from her backyard and then pours the sand into the terrarium. How many minutes does it take the mermaid to fill three-quarters of the terrarium with sand?
9514 1404 393
Answer:
105 minutes
Step-by-step explanation:
The volume of the terrarium is ...
V = LWH
V = (42 in)(10 in)(9 in) = 3780 in³
The volume of a box is ...
V = (3 in)(3 in)(3 in) = 27 in³
Then the number of boxes it takes to fill the terrarium is ...
(3780 in³)/(27 in³/box) = 140 boxes
The mermaid wants to fill it 3/4 full, so only needs 3/4 this number of boxes. That is 105 boxes. At the rate of 1 per minute, ...
it will take 105 minutes to fill 3/4 of the terrarium
