lin and her brother each dreated a scale drawing of their backyard, but at different scles. lin used a scale of 1 inch to 1 foot. her brother used a scale of 1 inch to 1 yard
1. express the scales for the drawings without units
2.whose drawing is larger? how mnay times as large is it? explain or show your reasoning
Answer:
Kindly check explanation
Step-by-step explanation:
Given:
Lin's drawing = 1 inch to 1 foot
Brother's drawing = 1 inch to 1 yard
1.) express the scales for the drawings without units
Convert both foot and yard to inch
1 foot = 12 inches
1 yard = 36 inches
Hence,
Lin's drawing : 1 : 12
Brother's drawing : 1 : 36
2.) whose drawing is larger? how mnay times as large is it? explain or show your reasoning
Lin's drawing is larger, this is because in Lin's drawing every 12 inch in the actual drawing represents 1 inch in the scale drawing( model)
While the brother's drawing is smaller with 36 inches in the actual drawing represented as 1 inch in the scale drawing.
(1/12) ÷ (1/36)
1/12 * 36/ 1
= 36 / 12
= 3. ; 3 times larger

Give an exact answer.
0.5(5 - 7b) = 8 - (4b + 6)
Answer:
b=-1
Step-by-step explanation:
Let's solve your equation step-by-step.
0.5(5−7b)=8−(4b+6)
Step 1: Simplify both sides of the equation.
0.5(5−7b)=8−(4b+6)
0.5(5−7b)=8+−1(4b+6)(Distribute the Negative Sign)
0.5(5−7b)=8+−1(4b)+(−1)(6)
0.5(5−7b)=8+−4b+−6
(0.5)(5)+(0.5)(−7b)=8+−4b+−6(Distribute)
2.5+−3.5b=8+−4b+−6
−3.5b+2.5=(−4b)+(8+−6)(Combine Like Terms)
−3.5b+2.5=−4b+2
−3.5b+2.5=−4b+2
Step 2: Add 4b to both sides.
−3.5b+2.5+4b=−4b+2+4b
0.5b+2.5=2
Step 3: Subtract 2.5 from both sides.
0.5b+2.5−2.5=2−2.5
0.5b=−0.5
Step 4: Divide both sides by 0.5.
0.5b/0.5=−0.5/0.5
b=−1

Durng lunch hour at a local reastrunt 90% of custmors order a meat entree and 10% order a vegetarian entree of the custmors who order a meat entree 80% order a drink of the custmors who order a vegitarian entree 40% order a drink what is the percent of custmors who order a drink for there entree
Answer:
First, here we must use the decimal notation for the percentages.
if we have a percentage x%, the decimal notation will be:
x%/100%.
Then for example, if x% = 90%.
the decimal notation will be:
90%/100% = 0.90
Data that we have:
90% order a meat entree, and 80% of these, order a drink.
So the percentage here that orders a drink is:
(0.9*0.8)*100% = 0.72*100% = 72%
10% order a vegetarian entree, and 40% of those order a drink, so the percentage here that orders a drink is:
0.1*0.4*100% = 0.04*100% = 4%.
Then the total percentage that orders drinks is 72% + 4% = 76%
76% of the customers that order an entree (meat or vegetarian) also order a drink.

Step-by-step explanation:
Step 1: Define
7x² - 3x - 6
x = 3
Step 2: Substitute and Evaluate
7(3)² - 3(3) - 6
7(9) - 9 - 6
63 - 15
48
Answer: 48
Step-by-step explanation: Plug in all x for 3
7(3)^2 Do exponent first then multiply. This equals 63
3x3 is 9
Then there is -6
63-9-6
This equals 48
Mr. Ha-Ha is a circus clown at the town carnival. He starts the day with 68 pieces of candy. At the end of the day he has given away 383 pieces of candy. How many more pieces of candy did he have to get to be able to give away that many pieces?

Answer: B
Step-by-step explanation:
Use the formula cos(A-B) = cosA cos B + sin A sin B.
if you use the Pythagorean theorem to find the other sides of Triangle A and B and use them to find the cosine of A and B, you should get:
(4/5)(sq rt of 5/3) + (3/5)(2/3)
(4 sq rt of 5/15) + (6/15)
4 sq rt of 5 + 6/15
An investor invested a total of $14,000. She divided the money into three different accounts. At the end of the year, she had made $670 in interest. The annual yield on each of the three accounts was 4%, 5%, and 6%. If the amount of money invested in the 5% account was the same as the combined amount invested in the 4% and the 6% accounts, determine how much was invested in the account that paid 6% interest.
Answer:
$2000
Step-by-step explanation:
Given the following :
Total amount invested = 14000
Total interest earned = 670
Amount invested in 4% (0.04) account = a
Amount invested in 6% (0.06) account = b
Amount invested in 5% (0.04) account = a + b
a + b + (a + b) = 14000
2a + 2b = 14000
a + b = 7000 - - - (1)
Simple interest = principal * rate * time
(a * 0.04) + (b * 0.06) + [(a+b) * 0.05] = 670
0.04a + 0.06b + 0.05a + 0.05b = 670
0.09a + 0.11b = 670 - - - - (2)
from (1)
a = 7000 - b
0.09(7000 - b) + 0.11b = 670
630 - 0.09b + 0.11b = 670
= 630 + 0.02b = 670
0.02b = 670 - 630
0.02b = 40
b = 40/ 0.02
b = $2000
Amout invested in 6% account = $2000

71 ×10 ^ 3 Scientific Notation
Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
7.1×1047.1×104
The required regular notation of 71 ×10³ Scientific Notation is71,000.
Given that,
Scientific notation is given of 71 ×10³ regular notation of the number is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
here,
Scientific notation = 71 ×10³
Regular notation = 71 ×10³
71 ×10³ = 71 * 10 * 10 * 10
71 ×10³ = 71000
Thus, the required regular notation of 71 ×10³ Scientific Notation is71,000.

3.) 4x + 6 = 14
Answer:
x=2
Step-by-step explanation:
4x + 6 = 14
4x = 14 - 6
4x = 8 (divide both sides by 4 to get x)
4x/4 = 8/4
x = 2
Answer:
Subtract 6 from both sides of the equation
4+6−6=14−6
Simplify
Subtract the numbers
4x+6−6=14−6
4=14−6
Subtract the numbers again
4x=14−6
4=8
Divide both sides of the equation by the same term
4=8
4 4
Cancel terms that are in both the numerator and denominator
x= 8

What is the equation of a line through point (-4,5) that is perpendicular
to the line with equation y= -6x+4?*
Answer:
set two equation of line y=ax+b and y=cx+d
when these two lines are perpendicular to each other, then a*c=(-1)
set answer is y=ax+b
we can know that a=1/6
bring in a=1/6 and(-4,5)
5=(1/6)*(-4)+b
=>5=(-2/3)=b
=>b=5 2/3
answer is y=(1/6)x+5 2/3
