A car travels at a steady speed. It covers 60km in 40 minutes. How far will it travel in 3 hours, assuming it continues at the same rate?
Answer:
270km
Step-by-step explanation:
3 hours is 180 minutes
40 minutes - 60km
180 minutes - x km
x = 180/40 * 60 = 270km (the speed is 90km/h)

Answer:
Step-by-step explanation:
This is a geometric sequence with first term a1 = 2 and common ratio r = 0.5.
an = a1 r^^n-1)
an = 2(0.5)^(n-1).
Recursive equation:
an = 0.5a(n-1) where n > 2
(1) Is climate change causing more severe storms? In a 2017 pre-Hurricane Irma
survey, 486 out of 1,080 adults answered in the affirmative. In a 2017 post-
Hurricane Irma survey, 546 out of 1,050 answered affirmatively. Establish a 90%
Confidence interval estimate of the difference (pre- minus post-hurricane) between
the proportions of adults pre-Hurricane Irma and post-Hurricane Irma who believe
climate change is causing more severe storms.
Answer:
90% Confidence Interval for difference in Proportion = (-0.106, -0.034)
Step-by-step explanation:
The formula for difference in proportions is given as:
p1 - p2 ± z × √p1(1 - p1)/n1 + p2(1 - p2)/n2
p = x/n
In a 2017 pre-Hurricane Irma
survey, 486 out of 1,080 adults answered in the affirmative.
x1 = 486
n1 = 1080
p1 = 486/1080 = 0.45
In a 2017 post- Hurricane Irma survey, 546 out of 1,050 answered affirmatively.
x2 = 546
n2 = 1050
p2 = 546/1050 = 0.52
Z score for 90% confidence interval = 1.645
Confidence Interval
=0.45 - 0.52 ± 1.645 × √0.45 (1 - 0.45)/1080 + 0.52(1 - 0.52)/1050
= -0.07 ± 1.645 × √0.0002291667 + 0.0002377143
=-0.07 ± 1.645 × √(0.000466881)
= -0.07 ± 1.645 × 0.0216074293
= -0.07 ± 0.0355442212
Confidence Interval
-0.07 - 0.0355442212
= 0.1055442212
Approximately = -0.106
-0.07 + 0.0355442212
= -0.0344557788
Approximately = -0.034
Therefore, 90% Confidence Interval for difference in Proportion = (-0.106, -0.034)

Which similarity statements are true
Please answer with explanation
Answer:
1. if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = 6/2= 3. Thus, the equation describing this direct variation is y = 3x.
2. Partial Variation, where two variables are related by a formula, such as the formula for a straight line (with a non-zero y-intercept)
example :
in the milk factory Carol makes $10 per hour but gets an extra $20 from another job. since Carol gets a $20 allowance regardless of how much she works, if we want to represent Carol's situation in the form of an equation, it would be
Y=10x + 20
therefore if she worked zero hours
(Y=10(0) + 20),
she would still make $20 unconditionally and for every hour she works, she gets $10 more including the initial $20.
thus Carol's equation would be a partial variation, since her income doesn't entirely depend on how much she works.
3. a relation is non linear because it is has a direct relationship between an independent variable and a dependent variable.
In a relation, changes in the output do not change in direct proportion to changes in any of the inputs.
relations does not create a straight line but instead creates a curve.

find the missing side lenght of the triangle below
Answer:
12
Step-by-step explanation:
5^2 + x^2 = 13^2
x = 12
Answer:
12
Step-by-step explanation:
Use Pythagorean theorem
[tex]a^2 +b^2 =c^2[/tex]
c= always hypotenuse/ longest side/ side across from right angle = 13
a= 5
[tex]5^2+b^2=13^2[/tex]
[tex]25+b^2=169[/tex]
Subtract 25 from 169
[tex]b^2= 144[/tex]
Square root both sides
b= 12

Answer:
4.5 cubic feet
Step-by-step explanation:
Volume is calculated by length ⋅ width ⋅ height.
In this situation, we need to find the volume of the box and subtract the volume of the present from the volume of the box.
2 1/2 ⋅ 2 ⋅ 1 1/2 = 7 1/2 cubic feet
Now that we have the volume of the box, we can subtract the volume of the present from it.
7 1/2-3 = 4.5 cubic feet
A ringtoss toy is composed of a rectangular prism on top of a cylinder. The rectangular prism is completely filled with water. The dimensions of the rectangular prism are shown in the diagram.
What is the volume of the rectangular prism in cubic centimeters?
165 cm3
270 cm3
348 cm3
26 cm3
Answer:
270 cm3
Step-by-step explanation:
The volume of the given rectangular prism is 270 cm³.
What is Volume?Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.
Volume is defined as the space occupied by an object inside the confines of three-dimensional space. It is also known as the object's capacity.
We have
Length = 9 cm
Width = 2 cm
Height = 15 cm
Using the formula for volume of the rectangular prism
= length x width x height
= 9 x 2 x 15
= 270 cm³
Thus, the volume of the given rectangular prism is 270 cm³.

The area of a rectangle is 12x^2 - 8x - 15. The width is (2x - 3). What is the length of the
rectangle?
Answer:
6x+5 us the length of the rectangle
Step-by-step explanation:
If A = 12x² - 8x - 15 and w = 2x - 3, then..
l = (12x² - 8x - 15)/(2x - 3)
= (2x - 3)(6x + 5)/(2x - 3)
= 6x + 5 cm
