Answer:
Graph D
Step-by-step explanation:
The slope of the data is 2.5 because 2.5 cups of flour are used for every ounce of butter. Some points on the graph we can use is (0,0) and (10,4).
(0,0): When there are 0 cups of flour, there are 0 ounces of butter.
(10,4): When there are 10 cups of flour, there are 4 ounces of butter.
Slope=m
[tex]m=\frac{Change(y)}{Change(x)}[/tex]
[tex]m=\frac{10-0}{4-0}[/tex]
[tex]m=\frac{10}{4}[/tex]
[tex]m=2.5[/tex]
Graph D is the only graph containing the point (10,4) and (0,0). So, Graoh D is the correct graph.
A five question multiple choice test has 4 choices for each question and only 1 correct answer each. What is the probability of guessing at least 3 out of the 5 questions correctly?
Answer:
Prob = 13/1024 = 0.0127
Step-by-step explanation:
Prob {A correct answer} = Correct option / Total options = 1/4
Prob {A wrong answer} = Wrong options / Total options = 3/4
Prob [3 answers correct] = P (3 correct ,& 2 wrong) or P (4 correct ,& 1 wrong) or P (5 correct, & no wrong)
= [ (1/4) x (1/4) x (1/4) x (3/4) x (3/4) ] + [ (1/4) x (1/4) x (1/4) x (1/4) x (3/4) ] + [ (1/4) x (1/4) x (1/4) x (1/4) x (1/4) ]
( 9/1024 ) + ( 3/1024 ) + ( 1/1024 )
13/1024 = 0.0127

===========================================================
Explanation:
The diagram shows that PT = 4 and QR = 5. Since QR is a radius of the circle, this means that the other radii segments TR and RS are also 5 units long.
Note how PR = PT+TR = 4+5 = 9, and how this segment is the hypotenuse for the right triangles PQR and PRS.
Picking either triangle, we have one known leg of 5 units (the radius mentioned earlier) and the other is unknown. The unknown leg is tangent to the circle, and recall that a tangent segment is always perpendicular to the radius at the point of tangency. So that's why we have right triangles.
Apply the pythagorean theorem to find the length of PQ and PS (both are the same length)
a^2 + b^2 = c^2
a^2 + 5^2 = 9^2
a^2 + 25 = 81
a^2 = 81 - 25
a^2 = 56
a = sqrt(56)
a = sqrt(4*14)
a = sqrt(4)*sqrt(14)
a = 2*sqrt(14)
The exact length of PQ and PS is 2*sqrt(14) units.
---------
We have enough to find the perimeter of quadrilateral PQRS. We add up the exterior sides. That means we ignore the interior segment PR.
perimeter = PQ+QR+RS+SP
perimeter = 2*sqrt(14)+5+5+2*sqrt(14)
perimeter = 10+4*sqrt(14)
Answer is choice B

Caroline has 12 cherries and 13 strawberries. What percentage are the cherries?
Answer:
12/25=48%
Step-by-step explanation:
total=denominator=12+13=25
numerator=no of cherries=12
12/25=x/100
1200=25x
x=48%
A percentage is a number or ratio that represents a fraction of 100.
Percentage formula = (Required number / Total number) x 100
The percentage of cherries is 48%.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
Example:
50% = 50 /100 = 1/2
25% = 25/100 = 1/4
We have,
Number of cherries = 12
Number of strawberries = 13
The total number of fruits:
= 12 + 13
= 25
Percentage formula = (Required number / Total number) x 100
The percentage of cherries:
= (Number of Cherries / Total number of fruits) x 100
= (12 / 25) x 100
[ 25 x 4 = 100 ]
= 12 x 4
= 48%
Thus,
The percentage of cherries is 48%.

Wanda uses 3.54 cups of flour to make 6 bagels. Eli uses 2.5 cups of flour to make 5 bagels. How much more flour per bagel is needed for Wanda's recipe?
Answer:
Wanda's recipe needs 0.09 more cups of flour per bagel.
Step-by-step explanation:
First, you have to find the amount flour that each of them need for one bagel by dividing the cups of flour they use by the number of bagels:
Wanda: 3.54/6= 0.59 cups of flour
Eli: 2.5/5=0.5 cups of flour
Now, you have to subtract the amount of flour Eli needs from the amount that Wanda needs:
0.59-0.5=0.09
According to thiss, the answer is that Wanda's recipe needs 0.09 more cups of flour per bagel.
Find the missing side. Round to the nearest tenth.
Step-by-step explanation:
sin x = 12/16 = 0.75
x = arc sin 0.75 = 48.6°
cos x = 36/40 = 0.90
x= arc cos 0.90 = 25.8°
cos x = 10/15 = 0.6667
x= arc cos 0.6667 = 48.2°
tan x = 30/18 = 1.6667
x = arc tan 1.6667 = 59.0°
What is the shape of the graph of the function?
h(t)=0.6⋅3.2^t
Answer:
A
Step-by-step explanation:
Here the base (3.2) is greater than 1 and the exponent (t) is positive. Thus the graph will have shape A.
The correct graph for the given function h(t)=0.6×[tex]3.2^{t}[/tex] will be upward increasing so option (A) will be correct.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given function is h(t)=0.6×[tex]3.2^{t}[/tex]
As t is increasing then the term [tex]3.2^{t}[/tex] will also go to increase since 3.2 is greater than 1.
Hence the value of the graph will go to increase as x increases so it is clear that option (A) will be correct.

Of the pizzas recently sold at Pizza Pies, 10 had pepperoni and 2 did not. Considering this data, how many of the next 6 pizzas sold would you expect to have pepperoni?
Answer:
1 pizza
Step-by-step explanation:
Of the pizzas recently sold at Pizza Pies, 10 had pepperoni and 2 did not.
This means, the total number of pizzas sold is
10 pepperoni + 2 pizzas without pepperoni = 12 pizzas
Hence, the number of 6 pizzas that would be sold without pepperoni is calculated as:
From the above question,
12 pizzas = 2 pizza without pepperoni
6 pizzas = x
Cross Multiply
12 pizzas × x = 6 Pizzas × 2 pizza without pepperoni
x = 6 Pizzas × 2 pizza without pepperoni/12 pizzas
x = 1 pizza without pepperoni
Therefore, 1 pizza would not have pepperoni out of 6 pizzas sold

Condense (cos92°)(cos133°)-(sin92°)(sin133°) into a singular trigonometric function expression, then find the exact value.
Answer:
-1/√2
Step-by-step explanation:
According to trigonometry identity
cos(A+B) = cosAcosB - sinA sinB
Given the expression
(cos92°)(cos133°)-(sin92°)(sin133°)
This can be expressed as cos(92+133) where A = 92, B = 133
(cos92°)(cos133°)-(sin92°)(sin133°)
= cos(92+133)
= cos225
= -0.7071
= -1/√2
Hence the exact value is -1/√2

find the volume
find 80% of whats left
divide by 1.75 (gas price)
sorry if its wrong but im human
will give you the steps but try to do the problem by yourself.
Start by finding the volume of the tank
Multiply 1.75 ft and 1.25 ft then covert the sum to inches by multiplying it by 12.
Then multiply that amount by the ll inches and you have the volume.
Since the tank is 20% full divide the volume by five, take the number you get from that and subtract it from the origanl volume.
Now you have the amount you need to fill.
Since it is 3.
Divide the amount you need to fill by 77 and you get the cost to fill the tank.

Step-by-step explanation:
surface area of a prism = 2(lw + wh + lh)
For the larger prism
Surface area = 2(2*10 + 2 * 12 * 10*12)
Surface area = 2(20+24+120)
Surface area = 2(164)
Surface area = 328sq.cm
For the smaller prism
Surface area = 2(3*6 + 3 * 8 * 6*8)
Surface area = 2(18+24+48)
Surface area = 2(90)
Surface area = 180 sq.cm
Surface area of the figure = 328 + 180
Surface area of the figure = 508sq. cm
