Answer:
72 kph
Step-by-step explanation:
The first sentence tells you the speeds are proportional. So, you can write the proportion ...
kph/mph = 120/75 = x/45
Multiplying by 45 gives x:
x = (45)(120/75) = 72
72 kph is 45 mph.

What is the total cost of a jar of jelly with a radius of 3 cm and a height of 10 cm if the cost is 0.04 cents per cm³? Use 3.14 for π. (Round to the nearest hundredth). 11.30 37.68 3.60 12.00
Answers
Answer: 11.30
Step-by-step explanation:
We wouod solve this using the formula:
= πr²h
= 3.14 × 3² × 10
= 3.14 × 9 × 10
= 282.6cm³
Since the cost is 0.04 cents per cm³, the total cost will then be:
= 282.6 × 0.04 cents
= 11.30 cents

Solve the simultaneous equations by substitution
2x+7y=5
x+y=5
Answers
Answer:
x = 6
y = -1
Step-by-step explanation:
i solved the second equation for 'y' to get 'y = 5 - x'
now i substituted that expression into the first equation for 'y'
2x + 7(5 - x) = 5
2x + 35 - 7x = 5
-5x = -30
x = 6
find 'y':
6 + y = 5
y = 5 - 6
y = -1
y=-1 and x=6
followed by the substitution method

Patty rolls a six-sided number die 120 times. How many times should she expect to roll a
prime number?
Answers
Answer is 60 times.
Explanation:
Prime numbers in a die are 2, 3 and 5 (i.e. 3 numbers)
Total outcomes can be 1, 2, 3, 4, 5 and 6 (i.e. 6 numbers)
Probability
= Number of preferred outcomes/ Total number of outcomes
= 3/6
= 1/2
= 0.5
Probability of getting a prime number while throwing the dice 120 times
= 0.5 × 120
= 60 times

Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and a half centimeters and three and a half centimeters. The altitude of the trapezoid is 4 centimeters.
Answers
Answer:
[tex]10cm^2[/tex]
Step-by-step explanation:
We are given that
Two parallel sides of trapezoid are
[tex]a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm[/tex]
[tex]b=3\frac{1}{2}=3+0.5=3.5 cm[/tex]
Height of trapezoid, h=4 cm
We have to find the area of the trapezoid.
We know that
Area of trapezoid=[tex]\frac{1}{2}(a+b)h[/tex]
Where a and b are two parallel sides
h=Height of trapezoid
Using the formula
Area of trapezoid=[tex]\frac{1}{2}(1.5+3.5)\times 2[/tex]
Area of trapezoid=[tex]10cm^2[/tex]

Answer:
13.7ft^2
Step-by-step explanation:
Area for triangle:
The formula for the area of a triangle in this scenario is area=(b*h)/2
The base length is 3.6ft and the height is 4.8ft. We can now substitute these values into the equation. So:
area=(3.6*4.8)/2
area=8.64ft^2 for the triangle
Area for semi-circle:
The formula for the area of a circle is area=pi*r^2. To find the area of the semi-circle, we can half the area of the circle at the end.
The question says to use 3.14 for the value of pi.
The diameter is given as 3.6ft, so to find the radius, we simply divide the diameter by 2; so 3.6/2=1.8ft for the radius
Now, we can just substitute these values into the equation above. So:
area=3.14*(1.8)^2
area=3.14*3.24
area=10.1736ft^2 (DO NOT ROUND THIS ANSWER!!).
However, this area is for the COMPLETE circle. We want the area for the semicircle shown above. Therefore, divide the circle area by 2. So:
10.1736/2=5.0868ft^2 for the semicircle.
Total area of shape
Now we have the area of the two separate shapes, we can simply add them together. So:
8.64ft^2 + 5.0868ft^2 = 13.7268ft^2 altogether (unrounded)
Now, finally we must round to 1/10, or to 1 decimal place. Therefore, the final value for the area would be 13.7ft^2.
Hope this helped!!

A clothes shop has some special offers.
T-shirts are buy one get one free and jumpers are 3 for 2.
The normal price of a T-shirt is £5.20 and the normal price of a jumper is £10.50.
How much does it cost to get 6 jumpers and 6 T-shirts using this offer as appropriate?
Answers
Answer:
£57.60
Step-by-step explanation:
The price of a T-shirt = £5.20
The price of a jumper = £10.50
To get 6 T-shirts, since there is an offer of buy one get one free; then the number of T-shirt to be paid for would be:
[tex]\frac{n}{2}[/tex] = [tex]\frac{6}{2}[/tex] = 3
The price of 3 T-shirts = £5.20 x 3
= £15.60
To get 6 jumpers, since there is an offer of buy 3 get 2 free; then the number of jumper to be paid for is 4.
The price of 4 jumpers = £10.50 x 4
= £42.00
Total cost of 6 jumpers and 6 T-shirts = £15.60 + £42.00
= £57.60

y=mx+b
m=slope=(y2-y1)/(x2-x1)
use the points (0,9) and (9,0)
(0-9)/(9-0) = -9/9 = -1
so m=-1
b is the y-intercept which is where x=0
the line crosses the y axis at y=9
so b=9
plugging in m and b into y=mx+b,
you get y=-x+9
