A man started a journey at 09:30 h and arrived at his destination in the same time zone, at 13:30 h on the same day. If his average speed was 30km/h, then the distance, in km, for the journey was
Answer:
120km
Step-by-step explanation:
We multiply 30km (thats how fast he was moving per hour) by the number of total hours during the journey, which is 4, 30 x 4 is 120km.

Answer:
∠1 = 103°
Step-by-step explanation:
supplementary angle to 136° = 180° - 136° = 44°
∠1 = 180° - 33° - 44° = 103°
Step-by-step explanation:
Let the unnamed angle in the triangle be x.
x + 136 = 180 (Sum of angles on the same straight line)
x = 180 - 136
= 44
Angle 1 + x + 33 = 180 (Sum of angles in a triangle)
Angle 1 + 44 + 33 = 180
Angle 1 + 77 = 180
Angle 1 = 180 - 77
= 103
A cat can eat 1/4 of a bag of food in 1/2 of a week. How much food can the cat eat in 1 week
Answer:
1/2 of a bag in a full week
Step-by-step explanation:
If they can eat a fourth of a bag and a half of a week then they can eat a half of a bag and a full week because to have is 1/4+1/4 which equals 1/2

What are my zeros (x^2 - 8x + 1)?
Answer:
x= 7.87298334621 x=.12701665379
Step-by-step explanation:
This is in standard form so we have to factor this into
x^2-8x + 16 + 1 = 16
(x-4)^2 = 15
(x-4) = [tex]\sqrt{15\\}[/tex]
x-4= ± 3.87298334621
x-4 = 3.87298334621 x-4= -3.87298334621
x= 7.87298334621 x=.12701665379

An architect is constructing a model in the shape of a triangle that has one side length of 9 centimeters and another side length of 8 centimeters. Which
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Sides:\ 9cm\ and\ 8cm[/tex]
The question is incomplete, as what is required is not state. However, a possible question could be to determine the possible side length of the third side.
To do this, we make use of the triangle inequality theorem which states that:
Given three sides (a, b and c) of a triangle, the following inequalities exist.
[tex]a + b > c[/tex]
[tex]a + c > b[/tex]
[tex]b + c > a[/tex]
Let a and b represent the two sides such that:
[tex]a = 9[/tex]
[tex]b = 8[/tex]
The inequalities become:
[tex]9 + 8 > c[/tex]
[tex]9 + c > 8[/tex]
[tex]8 + c > 9[/tex]
Solve for c in each:
[tex]9 + 8 > c[/tex]
[tex]17 > c[/tex]
[tex]c < 17[/tex]
[tex]9 + c > 8[/tex]
[tex]c > 8 - 9[/tex]
[tex]c > - 1[/tex]
[tex]8 + c > 9[/tex]
[tex]c >9 - 8[/tex]
[tex]c >1[/tex]
The value of c must be positive, so, we consider;
[tex]c >1[/tex] and [tex]c < 17[/tex]
Rewrite:
[tex]1 < c[/tex] and [tex]c < 17[/tex]
Combine both
[tex]1 < c < 17[/tex]
Hence, the value of c is:
[tex]c = (1,17)[/tex]
NO LINKS!! PLEASEE HELPP QUICK I POSTED THIS SO MANY TIMES AND NOBODY ANSWERS PLSSS HELP MEEE Write the slope-intercept inequality for the graph below. If necessary, use <=
fors or >= for >
Answer:
y ≤ -2x - 2
Step-by-step explanation:
Slope- intercept form is y = mx + b, m being the slope and b being the y-intercept.
The slope is the rise of the line over the run. We can choose two points that are exactly on the line. Let's try points (-1, 0) and (0, -2). The line slopes down, so we already know the slope is negative. From point (-1, 0), the line goes down 2 units and over 1 unit. So, the slope is -[tex]\frac{2}{1}[/tex]. We can also simply say that the slope is -2.
The line intersects with the y-axis at point (0, -2), so the y-intercept is -2.
Because the shading is on the left side of the line and the line is solid, we can tell that y is less than or equal to -2x - 2. So, the equation is-
y ≤ -2x - 2

Does -6^2 = (-6)^2? Explain your answer.
PLEASE HELP!!!!!!!
Answer:
No it doesn't
You see when something is in parenthesis () that means it isolated as a whole. When it says (-6)^2 that means Negative six squared. When it says -6^2 that means only the 6 will be squared since they are not parenthesized. So by isolating the two figures both of those numbers together will be squared whereas when they arent isolated only one of them will be squared.
(-6)^2 = -6 x -6 = 36
-6^2= - x 6 x 6= -36
Answer:
-6^2 is same as (-6)^2
Therefore, - 6^2 is - 6×-6 WHICH IS EQUALS TO 36
(-6)^2 = - 6×-6=36
36=36 is the answer.

The area of a square playground (in square feet) can be represented by x2 - 30x + 225. How many feet is the perimeter of the playground if x = 25?
Answer:
40
Step-by-step explanation:
Substitute 25 for x
[tex] {25}^{2} - 30(25) + 225 = 100[/tex]
100 is the area of the square so that means
10 is the side length of each side of the square.
Multiply 4 by 10 to get the perimeter.
[tex]4 \times 10 = 40[/tex]
I need help plz. Can anyone help me ASAP?
Answer:
6 + 4d + 11c
Step-by-step explanation:
In order to find the perimeter, you add up all the side lengths which would be expressions in this case
(10c + 10) + (c + 5) + (4d - 9)
add like terms: (10c + c) + (10 + 5 - 9) +4d
= 11c + 6 + 4d
which is the same as 6 + 4d + 11c, I just added them in a different order.

You are drawing a map of your school and want to make sure all the measurements are accurate. You decide to use a scale of 1 cm = 3 feet. In your drawing, the main hallway ends up being 12 cm long.
The drawing is a little too big so you decide to change the scale to 1 cm = 4 feet.
Keeping the length in feet the same, how many centimeters long should the main hallway be in your new drawing?
Answer:
the main hallway should be 12cm in the new drawing

write the equation, please.
Answer:
x^2+y^2 = 49
Step-by-step explanation:
This is a circle.
The generic equation of a circle is
(x-h)^2+ (y-k)^2 = r^2
where (h,k) is the center and r is the radius
The center of the circle is at the origin which is (0,0)
The radius is 7
(x-0)^2+(y-0)^2 = 7^2
x^2+y^2 = 49
Answer:
[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]
Step-by-step explanation:
we are given a circle
we want to figure out the equation of the circle
remember that,
[tex] \rm \displaystyle E _{c} : (x - {h)}^{2} + (y - k {)}^{2} = {r}^{2} [/tex]
(h,k) are the centre of the circle
we can clearly see that the centre of the circle is (0,0) and the redious is 7 units
thus substitute:
[tex] \displaystyle (x - {0)}^{2} + (y - 0{)}^{2} = {7}^{2} [/tex]
further simplification is needed:
[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]
and we are done!
The two legs of a right triangle measure 7 inches and 5 inches. Find the measure of the acute angle that is included between the longer leg and the hypotenuse. WILL GIVE BRAINIEST TO FIRST RIGHT ANSWER
Answer:
44.4 degrees
Step-by-step explanation:
Given the following
Hypotenuse = 7
Longer leg = 5 (adjacent])
Let the acute angle angle between both sides be x
According to SOH CAH TOA
Cos theta = adj/hyp
Cos x = 5/7
x= arccos (5/7)
x = arccos (0.7143)
x = 44.4degrees
Hence he measure of the acute angle that is included between the longer leg and the hypotenuse is 44.4 degrees
What’s the probability?
Answer:
[tex]\frac{1}{8}[/tex]
Step-by-step explanation:
The probability for a flip on either side of the coin is always 50% or [tex]\frac{1}{2}[/tex]
So to get the probability for the three flips just do:
[tex](\frac{1}{2}) ^{3}[/tex] or [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex]
Either way you solve it the answer is [tex]\frac{1}{8}[/tex]
What is the answer to c to the fifth power, times c to the eighth power, times c to the negative fifth power?
Answer:
c^8
Step-by-step explanation:
Expressing the above Mathematically ;
c^5 * c^8 * c^-5
From.rules of indices :
a^x * a^y = a^(x + y)
Therefore, applying the rule of indices ;
c^5 * c^8 * c^-5 = c^(5 + 8 + - 5)
c^5 * c^8 * c^-5 = c^(5 + 8 - 5)
c^5 * c^8 * c^-5 = c^8
Hence,
c^5 * c^8 * c^-5 = c^8
