Answer:
64°
Step-by-step explanation:
So supplement angles are equal to 180, so first our two angles added together will be 180:
x + x = 180
Now one of these angles is 6 greater than half:
x + (x/2 + 6) = 180
Then we will solve for x:
x + (x/2 + 6) = 180
x + x/2 + 6 = 180
x + x/2 = 174
[tex]\frac{3}{2}[/tex]x = 174
x = 116
Plug it back in:
x + (x/2 + 6) = 180
/\
x/2 + 6
(116)/2 + 6
64
To check:
116 + 64 = 180 ✓

"Find the total area of the shape"
How should I solve this? The answer is 31.9 cm²
Answer:
31.9 cm² (3 s.f.)
Step-by-step explanation:
[tex]\boxed{area \: of \: sector = \frac{θ}{360º} \times \pi {r}^{2} }[/tex]
∠AOD
= 360° -60° - 120° -45° (∠s at a pt.)
= 135°
Area of shape
[tex] = \frac{60°}{360°} (\pi)({2}^{2}) + \frac{120°}{360°} (\pi)(3^{2} )+ \frac{45°}{360°}(\pi)( 5 {}^{2}) + \frac{135°}{360°} (\pi)(3 {}^{2} )[/tex]
[tex] = \frac{1}{6} (4\pi) + \frac{1}{3} (9\pi) + \frac{1}{8} (25\pi) + \frac{3}{8} (9\pi)[/tex]
[tex] = \frac{4}{6} \pi + \frac{9}{3} \pi + \frac{25}{8} \pi + \frac{27}{8} \pi[/tex]
[tex] = \frac{61}{6} \pi[/tex]
= 31.9 cm² (3 s.f.)

2. A coupon has been issued for crackers at the local grocery store. The crackers originally retail for $3.79 a box and the coupon is good for 10% off the price marked on the shelf. When you arrive at the store the crackers are already marked down by 15%. What is the price you will pay for the box of crackers?
Answer:
$3.54
Step-by-step explanation:
$3.79-25% (because you add the 15% + 10%)
which is $3.54
Answer:
$2.90
Step-by-step explanation:
start with original price
$3.79
marked down 15%
3.79 × .15 = .5685 or .57
3.79 - .57 = 3.22 price on shelf
minus 10% coupon
3.22 × .1 = .322 or .32
$3.22 - .32 = $2.90

Use the graph to determine the following.
a. the function's domain
b. the function's range
c. the x-intercepts, if any
d. the y-intercept, if any
e. the function values, f(1) and f(4).
Assume that the graph of the function
continues its trend beyond the displayed coordinate grid.
From the graph of function,
a. Domain = (-∞, ∞)
b. Range = [-2, -∞)
c. x-intercept = NA
d. y-intercept = (0, -4)
e. f(1) = -3 and f(4) = -4
What is domain of a function?"It is a set of points which for which the function is well defined."
What is the range of the function?"It is the set of all possible output values."
What is intercept?"It is a point at which the graph of the function intersects the x-axis or y-axis."
For given example,
From the graph of a function we can observe that, function takes all values of x
So, domain = (-∞, ∞)
The value of the function starts from -2 and it tends towards -∞.
So, Range of f(x) = [-2, -∞)
From the graph of a function we can observe that the graph of a function does not intersect the x-axis.
So, for given function has no x-intercept.
The graph of the function intersects y-axis at (0, -4).
So, y-intercept = (0,-4)
We need to find the value of f(1) and f(4)
From the graph,
for x = 1,
⇒ f(1) = -3
for x = 4,
⇒ f(4) = -4
Therefore, from the graph of function,
a. Domain = (-∞, ∞)
b. Range = [-2, -∞)
c. x-intercept = NA
d. y-intercept = (0, -4)
e. f(1) = -3 and f(4) = -4

Find the slope of the line that passes through (7, 10) and (5, 13).
Answer:
it is -3/2
Step-by-step explanation:
use rise/run or y/x to find slope. Start with the lower x value, so the run (movement on the x axis) is 2 so plug that in, rise/2. Fine the rise whish is -3, plug that in and you get -3/2

A store buys a TV for $100. They sell it for a 70% mark-up. What is the new cost of the TV?
Answer:
170
Step-by-step explanation:
Since the TV is worth $100 initially but has a 70% markup, it means they increased the price by the percent markup
100 x .70 = 70
100 + 70 = $170
The new cost of the TV sold at this store is equal to $170.
Given the following data:
Cost price = $100Markup = 70%To determine the new cost of the TV sold at this store:
How to calculate markup price.We would calculate the markup price by multiplying the cost price by the markup.
[tex]Markup\;price = \frac{70}{100} \times 100\\\\Markup\;price = 0.7\times 100[/tex]
Markup price = $70
Now, we can find the new cost of the TV:
[tex]New\;cost = Markup\;price + Cost\;price\\\\Total\;cost = 70 + 100[/tex]
Total cost = $170.
