Step-by-step explanation:
Given
(a) to (d)
Required
Which equals 13
[tex](a):\ 9 + 3 * (2 \div 3) + 6[/tex]
Solve the bracket
[tex]9 + 3 * (2 \div 3) + 6 =9 + 3 * (\frac{2}{3}) + 6[/tex]
Open the bracket
[tex]9 + 3 * (2 \div 3) + 6 =9 +2 + 6[/tex]
[tex]9 + 3 * (2 \div 3) + 6 == 17[/tex]
[tex](b):\ (9 + 3) * 2 \div 3 + 6[/tex]
Solve the bracket
[tex](9 + 3) * 2 \div 3 + 6 =(12) * 2 \div 3 + 6[/tex]
Open bracket
[tex](9 + 3) * 2 \div 3 + 6 =24 \div 3 + 6[/tex]
Divide
[tex](9 + 3) * 2 \div 3 + 6 =8 + 6[/tex]
[tex](9 + 3) * 2 \div 3 + 6 =14[/tex]
[tex](c)\ 9 - (3 * 2) \div 3 + 6[/tex]
Solve the bracket
[tex]9 - (3 * 2) \div 3 + 6 =9 - (6) \div 3 + 6[/tex]
Remove bracket
[tex]9 - (3 * 2) \div 3 + 6 =9 - 6 \div 3 + 6[/tex]
Divide
[tex]9 - (3 * 2) \div 3 + 6 =9 - 2 + 6[/tex]
[tex]9 - (3 * 2) \div 3 + 6 =13[/tex]
[tex](d)\ (9 + 3 * 2) \div 3 + 6[/tex]
Solve the bracket (the product, first)
[tex](9 + 3 * 2) \div 3 + 6=(9 + 6) \div 3 + 6[/tex]
[tex](9 + 3 * 2) \div 3 + 6=15 \div 3 + 6[/tex]
Divide
[tex](9 + 3 * 2) \div 3 + 6=5 + 6[/tex]
[tex](9 + 3 * 2) \div 3 + 6=11[/tex]
Only (c) equals 13

Bilbo found a great deal on rings. He bought a ring for 70% of the original price. If he saved $45, what was the original price?
Answer: $150
Step-by-step explanation:
If Bilbo bought the ring for 70% of the original price, this means that he saved:
= 100% - 70%
= 30%
$45 is therefore 30% of the original price.
Assuming the original price is x:
30% * x = 45
x = 45/30%
x = $150

44.95
19.73
39.82
40.31
Answer:
Option B
Step-by-step explanation:
By applying cosine rule in the given triangle ABC,
BC² = AC² + AB² - 2(AC)(AB)cos(∠A)
BC² = (26)² + (23)² - 2(26)(23)cos(47°)
BC² = 676 + 529 - 815.67
BC² = 389.33
BC = √(389.33)
BC = 19.73
Therefore, Option B will be the correct option.

A city manager made a scatter plot of the number of retail stores in a certain city over the years. The scatter plot had a trend line with an equation of y = 11x + 12, where y is the total number of retail stores and x is the number of years since 1990 Mark and his family moved to the city in 1997. Use the equation to predict how many retail stores there were in 1997.
If the number of the years will be 7. Then the number of the retail stores will be 89.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A) 18
B) 27
C) 9 square root 3
D) 24

Answer:
B
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{g}{18\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2g = 54 ( divide both sides by 2 )
g = 27 → B

20 people each bring 3 food dishes to an awards banquet. The dishes are shared equally by 180 people at the banquet. How many people share 1 food dish?
Answer:
3 people
Step-by-step explanation:
If 20 people each bring 3 food dishes to an awards banquet, the total amount of food brought will be (20 * 3) = 60foods
If the dishes are shared equally by 180 people at the banquet, then;
60foods = 180 people
1 food = x
Cross multiply
60* x = 180
60x = 180
x =180/60
x = 3
Hence 3 people will share 1 dish

Find the equation of the line shown
Answer:
y = 2x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = B(- 3, - 1 ) and (x₂, y₂ ) = A (1, 7)
m = [tex]\frac{7+1}{1+3}[/tex] = [tex]\frac{8}{4}[/tex] = 2 , then
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, 7 ) , then
7 = 2 + c ⇒ c = 7 - 2 = 5
y = 2x + 5 ← equation of line
The maintenance crew of a hotel has to monitor the temperature of the hotel pool and hot tub. To enhance comfort, the management team requests that the mean pool temperature and the mean hot tub temperatures not differ by more than 15 degrees. To estimate the difference in these mean temperatures the maintenance crew selects a random sample of 8 times to check the hot tub temperature and a random sample of 10 times to check the pool temperature. Although the sample sizes are small, the distribution of temperature for the pool and for the hot tub does not show strong skewness or any outliers. The mean pool temperature is 86 degrees with a standard deviation of 3 degrees. The mean hot tub temperature is 101 with a standard deviation of 1.8 degrees. What is the correct 95% confidence interval for the true difference in the population means (hot tub – pool)? Use the conservative df.

Step-by-step explanation:
Springs are used to measure the mass of objects. The extension of a spring, E centimeters, is
directly proportional to the mass, M kilograms, of the object hanging from the spring. A 4-kg
load stretches a spring by 2.5 cm. If a 6-kg load is hung on the spring, find the extension of the
spring in centimeters.
Answer:
The extension of the 6-kg load is 3.75 cm
Step-by-step explanation:
4/2.5 = 6/x
Cross multiply:
4x = 15
15/4 = x
x = 3.75
