A kangaroo hops 2 kilometers in 3 minutes. At this rate how long does it take the kangaroo to travel 3 kilometers?
Answers
Answer:
4 minutes 3 seconds
Step-by-step explanation:
Step one:
Given data
A kangaroo hops 2 kilometers in 3 minutes
The rate/speed is
rate/speed= 2/3 km per minute
Required
the time taken to cover 3 km
Step two:
We know that
rate= distance/time
2/3= 3/t
cross multiply we have
2t=3*3
2t=9
divide both sides by 2
t= 9/2
t= 4.5 minutes
t= 4 minutes 3 seconds
solve for a.
a + (-7) = -17
A. a = -24
B. = -10
C. a = 10
D. a = 24
Answers
Answer:
the answer is A
Step-by-step explanation:
-17 - (-7) = -24
a = -24
Answer:
b) a = -10
Step-by-step explanation:
a + (-7) = -17
simplify
a - 7 = -17
add 7 to both sides of the equation
a - 7 + 7 = -17 + 7
a = -17 + 7
a = -10
Clare has a recipe for yellow cake she uses 9 1/3 cups of flour to make 4 cakes. Noah will follow the same recipe. He will make c cakes using f cups of flour. What equation would show the relationship between cake and flour?
Answers
Answer:
[tex]c=\frac{3}{7}f[/tex]
Step-by-step explanation:
Clare uses [tex]9\frac{1}{3}[/tex] cups of flour to make 4 cakes.
Noah follows the same recipe so the ratio of the ingredients used will be proportional.
If Noah uses f cups of flour for c cakes,
[tex]\frac{c}{f} =\frac{4}{9\frac{1}{3}}[/tex]
[tex]\frac{c}{f} =\frac{4}{\frac{28}{3}}[/tex]
[tex]\frac{c}{f} =\frac{4\times 3}{28}[/tex]
[tex]c=\frac{3}{7}f[/tex]
Therefore, relation between cake and flour used is,
[tex]c=\frac{3}{7}f[/tex]
The cost price of a car is 450 naira and the selling price is 504 naira what is the percentage again
Answers
Answer:
12%
Step-by-step explanation:
The car is sold at a gain because its selling price is greater than cost price
Profit = [(selling price - cost price) / cost price ] x 100
[tex]\frac{504 - 450}{450}[/tex] x 100
[tex]\frac{54}{450}[/tex] x 100 = 12%.

At dinner, the meal cost $24 and the sales tax was $1.32. What was the tax rate? Write your answer as the percent with no % sign
Answers
Answer:
5.5
Step-by-step explanation:
Sales tax = tax rate × Cost of meal
Sales tax = $1.32
Tax rate = x%
Cost of meal = $24
Sales tax = tax rate × Cost of meal
1.32 = x% × 24
1.32 = x/100 × 24
1.32 = 24x/100
1.32 * 100 = 24x
132 = 24x
x = 132/24
x = 5.5%
= 5.5

Select the correct answer. Which number has a terminating decimal expansion? A. 2/7 B.√12 C. 5/8 D. 2/11
Answers
Answer:
Option C is correct option.
Step-by-step explanation:
We need to determine which number has a terminating decimal expansion.
Terminating decimal
A decimal number that contains a finite number of digits after the decimal point is called terminating decimal .
for example 0.123 is terminating decimal as it has finite number of digits after decimal point.
Now, we will look at each option to find the terminating decimal
A. 2/7
Converting in decimal form: 0.28571....
As it doesn't contain finite numbers after decimal point, so 2/7 is not terminating decimal.
B.√12
Converting in decimal form: 3.46410....
As it doesn't contain finite numbers after decimal point, so √12 is not terminating decimal.
C. 5/8
Converting in decimal form: 0.625
As it contain finite numbers after decimal point, so 5/8 is terminating decimal.
D. 2/11
Converting in decimal form: 0.18181....
As it doesn't contain finite numbers after decimal point, so 2/11 is not terminating decimal.
Therefore, Option C is correct option.

Which relationships describe the angle pair x° and 157°? Select each correct answer. O complementary angles 1570 O supplementary angles o adjacent angles vertical angles
Answers
Answer:
Supplementary angles and adjacent angle
Step-by-step explanation:
Both angles x° and angle 157° are supplementary ; this is because the sum of both angles should add up to 180°.Looking closely, each both angles will combine to form angle on a Straight line which from angle theorem adds up to 180°.
Also both angles x° and 157° are adjacent angles most simply because they share a common vertex(this can be interpreted as the point of intersection of the two lines which makes up the diagram.)

how do you solve systems by graphing
Answers
Answer:
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system.

The graph of y = f(x) is the solid black graph below. Which function represents the dotted graph?
Answers
Answer:
C (The lower left one)
Step-by-step explanation:
I saw that the vertex was equal to (-1,1) and that is the only answer that makes sense
The graph of the function y = x shifted 1 unit up and moved 1 unit to the left
so the new function is now y = (x + 1) + 1.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
By observing the figure we conclude that it shifted 1 unit up and moved 1 unit to the left.
If the original graph was y = x now it is y = (x + 1) + 1.

Janice rolls a fair number cube sixty times. She rolled the number four 12 times.
What is the experimental probability of rolling the number four?
Answers
Answer:0.5
Step-by-step explanation:
60➗12
Probability of an event is the measure of its chance of occurrence. The experimental probability of Janice rolling the number four is 0.2
What is experimental probability?Experimental probability calculates the probability of some event from the results of experiments.
For an event E, we get the experimental probability of that event
[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]
where, [tex]P_e(E)[/tex] is denoting experimental probability of occurrence of E.
For this case, we're specified that:
The event in consideration is "Rolling the number 4"
The times she rolled the number 4 is: 12
She got four 12 times in 60 rolls of the considered cube.
Thus, we have:
E = Rolling the number 4 on the considered cubeNumber of times E occured = 12Number of times experiment was done = 60Thus, we get:
[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}} = \dfrac{12}{60} = \dfrac{1}{5} = 0.2[/tex]
Thus, the experimental probability of Janice rolling the number four is 0.2
