Answer:
The total hours of exercising is 2 hours and 15 minutes.
27 minutes is your total of him playing soccer. i got this by getting the minutes from the total time, so 135 and I divided it by 5 and got 27 or you could even know that 1/5 of an hour is 12 and multiply that by 12 and 1/5 of 15 is 3 so it equals 27 minutes!
Answer:
28.8 minutes
Step-by-step explanation:
Total hours the student exercised = 2hours 15 minutes. = 2.4 hours.
Given that:
1/5 of this came from soccer, so we must find 1/5 of 2.4:
1/5 x 2.4 = 0.48 hours.
We can write this as minutes = 28.8 minutes.
So, the student plays soccer for 28.8 minutes.
hope this helps.
Good Luck

In year 3, it is expected that the total value of clothing sales will reach $32 million. If the total value of azco sales remain the same as year 2, what percentage of sales would clothing account for in year 3
Answer:
32 million / x million year 3 * 100%
Step-by-step explanation:
Since they mention that the total value of azco sales remain the same as year 2, therefore the earnings for year 2 and 3 are the same.
Which means that the percentage of sales profits would be 32 million dollars divided by the profits of year 3, which we do not know because the statement does not tell them but they tell us that they do not change with respect to year 2.
Therefore the percentage would be:
32 million / x million year 3 * 100%

Answer:
Number that fits in the green box is 4.
Step-by-step explanation:
Coordinates of a point P are (5, 4)
Rule for the rotation of a point (x, y) 270° counterclockwise about the origin is,
(x, y) → (y, -x)
By this rule, image of the point P(5, 4) will be,

How does the value of b affect the graph of y=m+b?
Answer:
b is the intercept of the graph. When x is 0, b is the y-value.
b affects the y-values, rather than the x-values. That means that it translates the graph up or down the y-axis by b units.

Jafar will get $12400 more if his salary is increased by 31%. Jafar's salary is 20% less of his colleague Ali's salary. What is Ali's salary?
Answer:
Ali's salary is $50000.
Step-by-step explanation:
Let Jafar's salary be x.
(31/100)*x = 12400
x = (12400*100)/31
x = 400*100
x = $40000
Let Ali's salary be y.
y-[(20/100)*y] = 40000
y-(y/5) = 40000
(5y-y)/5 = 40000
4y = 200000
y = $50000

boxes A and B contain some counters
box A contains more counters than box B
box A: 4k counters
Box B: k+9 counters
what is the smallest possible value of K
Step-by-step explanation:
If we take 4 as k then
4k = 4(4) = 16 boxes
k + 9 = 4 + 9 = 13 boxes
Answer:
4
Step-by-step explanation:
Box A = 4k
Box B = k+9
Box A > Box B
=> 4k > k+9
Subtracting k to both sides
=> 4k-k > 9
=> 3k > 9
Dividing both sides by 3
=> k > 3
So, The smallest possible value of k is 4
In a local ice sculpture contest, one group sculpted a block into a rectangular-based pyramid. The dimensions
of the base were 3 m by 5 m, and the pyramid was 3.6 m high. Calculate the amount of ice needed for this
sculpture
Answer:
Step-by-step explanation:
To calculate the amount of ice needed for this sculpture, we would apply the formula for determining the volume of a rectangular base pyramid which is expressed as
Volume = 1/3 × base area × height
Since the base is rectangular, base area = length × width = 3 × 5 = 15 m
Given that height = 3.6m, therefore, the amount of ice needed for this sculpture is
1/3 × 15 × 3.6 = 18 m³
Answer: To calculate the amount of ice needed for this sculpture, we would apply the formula for determining the volume of a rectangular base pyramid which is expressed as Volume = 1/3 × base area × heightSince the base is rectangular, base area = length × width = 3 × 5 = 15 mGiven that height = 3.6m, therefore, the amount of ice needed for this sculpture is 1/3 × 15 × 3.6 = 18 m³

What is 6.5982 rounded to 3 decimal places?
Answer:
6.598
Step-by-step explanation:
=> 6.5982
While rounding to 3 dps, we look at the digit in ten thousandths place. If it is greater than 5, we'll add 1 in the thousandths place but if it is smaller than 5, we won't add anything.
=> Here, the digit in ten thousandths place is less than 5. So, after rounding off to 3 dps the number becomes
=> 6.598
Answer:
6.598.
Step-by-step explanation:
The number listed has four decimal places. To have three decimal places, it must cut off the last number. Since the last number is less than five, we round down to make the answer 6.598.

Answer:
x < 4
Step-by-step explanation:
3x - 3 < 9
3x < 12
x < 4
Answer: x < 4
Step-by-step explanation:
3x < 9 + 3
you’re going to add the two (9+3= 12) numbers.
3x < 12
Then divide both sides of the inequality by 3.
3x < 12 = x < 4.
A man has a 10m X 10m square garden. In the center is a 2m X 2m square patch which he cannot use. He divides his usable space into four congruent rectangular patches, each of which measures
Answer:
4m X 6m
Step-by-step explanation:
This is because if there is a 2m square in the middle, there is 8 m of usable space left along both sides of the garden.
Because the 2m square was in the middle, there is 8/2 = 4m along each width of the 4 small rectangles.
Becuase 4m is the width, there is 10 - 4 = 6m along each rectangle's length.
The 4m is the width, there is 10 - 4 = 6m along each rectangle's length. the area he will use is 4m x 6m.
What is reflexive property of congruence?The reflexive property of congruence says that the considered geometric quantity, whether it be angle, line segment, or shape etc, is congruent to itself.
Given information; A man has a 10m X 10m square garden. In the center is a 2m X 2m square patch we need to find which he cannot use.
He divides his usable space into four congruent rectangular patches.
If there is a 2m square in the middle, there is 8 m of usable space left along both sides of the garden.
The 2m square was in the middle, there is 8/2 = 4m along each width of the 4 small rectangles.
The 4m is the width, there is 10 - 4 = 6m along each rectangle's length.

Find the value of x.
Answer:
x=6.09cm
Step-by-step explanation:
Working out AB:
7.5²+4.9²
= √80.26
AB= 8.96cm
To work out x:
AB is the opposite, where BC is the adjacent. This means that we have to use TOA.
x=8.96/Tan(55.8)
x= 6.09cm
Answer:
6.1 cm
Step-by-step explanation:
Use the Pythagorean theorem for triangle ABD to find the hypotenuse.
7.5^2+4.9^2=c^2. After solving you get that the missing length is about 9 cm. The hypotenuse of ABD is also a leg for ABC so you can use a trigonometric function, tangent, to find x. Set up the equation for opposite and adjacent sides to angle measure 55.8. The equation is tan(55.8)=9/x. In order to isolate the variable you multiply both sides by x to get (x)tan(55.8)=9, then divide both sides by tan(55.8), this leaves you with x=9/tan(55.8). You can then plug this into the calculator to get x is approximately 6.1 cm.

Answer: b) The mixture has the intended number of pounds and costs more than the intended amount.
Step-by-step explanation: At the point D, there is an equal amount of milk and dark chocolate—they each have 25 pounds. This correlates with the equation of line b: x+y=50. 25+25=50
Since the variable y is the amount of Milk Choclate and the variable x is the amount of Dark Chocloate, the equation of line a: 4x + 2y = 130 can be used. So then you plug in the amount of milk chocolate as “x” and amount of dark chocolate “y“. 4(25) + 2(25) =150.
150 is not equal to 130, so even though it has the intended number of pounds, it costs $150 instead of $130, so it costs more than the intended amount
So be is the answer

Kira drew traingle pqr and stu so that angle p is congruent to angle s, angle q is congruent to angle t, pr equals 12, and su equals 3. Are triangles pqr and stu similar? If so identify the similarity postulate or theorem that applies
Answer:
The similarity postulate theorem is;
Similar - AA
Step-by-step explanation:
We are told that angle p is congruent to angle s, angle q is congruent to angle t.
Thus it is an AA similarity theorem because AA similarity theorem states that: If two angles in one triangle are congruent/respectively equal to two angles of another triangle, then the 2 triangles are similar.
For example, if we assume ΔABC and ΔDEF to be two triangles such that ∠A = ∠D and ∠B = ∠E. Then the two triangles are equiangular and thus they are similar by AA.
Answer: similar AA is correct

which term of the AP:3,15,27, 39,.....will be 132 more than its 54th term
Answer:
n=65th term
Step-by-step explanation:
AP:3,15,27,39......
From the AP
a=3
a+d=15
a+2d=27
3+d=15 (1)
3+2d=27 (2)
Subtract (1) from (2)
We have,
2d-d=27-15
d=12
54th term=a+(n-1)d
=3+(54-1)12
=3+(53)12
=3+636
=639
The term is 132 more than the 54th term
132+54th term
=132+639
=771
Find the term
771=a+(n-1)d
771=3+(n-1)12
771-3=12n-12
768=12n-12
768+12=12n
780=12n
n=780/12
=65
n=12
The term which is 132 more than the 54th term is the 65th term

which line is perpendicular to the line y= -1/3 x - 2 and passes through the point (1,4)?
Answer:
y = 3x + 1
Step-by-step explanation:
y= -1/3x
perpendicular so y = 3x + b
the line goes through (1,4), so substitute to find the value b , which is where the line intersects with the y axis.
4 = 3*1 +b
so b = 1
y = 3x + 1
Choose the slope and y-intercept that
correspond with the graph.
Answer:
slope = 2 and y- intercept = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (2, 2)
m = [tex]\frac{2+2}{2=0}[/tex] = [tex]\frac{4}{2}[/tex] = 2
The y- intercept is the value of the y- coordinate at the point where the line crosses the y- axis, that is
y- intercept = - 2
