1200 bricks each of 0.075m3 volume are required to construct a wall of length 25m and height 9m. Find the breadth of the wall.
Here's the solution,
Volume of wall :
=》total bricks × volume of each brick
=》1200 × 0.075 m³
=》90 m³
volume of wall :
=》lenght × width × height
=》25 × 9 × width
=》225 × width
now, by equating the volumes, we get
( since they are volume of same wall )
=》225 × width = 90
=》width = 90 ÷ 225
=》width of wall = 0.4 m

Answer:
x = 4
Step-by-step explanation:
Here, given that the two triangles are similar, we want to find the value of x
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
Thus, we have it that;
ED/EF = XY/YZ
5/2x-1 = 10/14

Answer:
p = 5/12
Step-by-step explanation:
-14+6p = -9-6p
Add 6p to each side
-14+6p+6p = -9-6p+6p
-14 +12p = -9
Add 14 to each side
-14+12p = -9 +14
12p =5
Divide by 12
12p/12 = 5/12
p =5/12

Answer:
[tex]46^{\circ}[/tex]
Step-by-step explanation:
Since the pair of angles are complimentary (add up to [tex]90^{\circ}[/tex]), as denoted by the right angle, we have the following equation:
[tex]44+x=90,\\x=90-44,\\x=\boxed{46^{\circ}}[/tex]
Answer:
46°
Step-by-step explanation:
ok first of all the angle looks like a 90° meaning 90 - 44 = 46
and the angle cant be above 120° anyways because 120 + 44 = 164
and the angle is way to small, 164° is almost a straight line, and so is 165° and 175° for the other answers
Write an equation for..
“The child’s tickets cost $4 each and the adult’s ticket cost $8 each. Write an equation that would represent the total cost, T, of purchasing a child’s tickets, c, and an adult’s tickets, a.”
Answer:
cxa=t cause you are mulltipling to find the total cost
Answer:
Step-by-step explanation:
A child´s ticket costs $4 and adults ticket costs $8. If we want one of each we need to add both numbers together, 4 plus 8 equals 12. The total cost of a child ticket and an adult ticket is $12.
The questions asked to write an equation; the equation would be:
C+A=T it could also be written as A+C=T, T=A+C or T=C+A.

What is Right Angled Triangle?Right angled triangle are those triangle for which one of the angle is 90 degrees.
For any angle, X, in a right triangle, trigonometric ratios are defined as,
sin X = opposite side / hypotenuse
cos X = adjacent side / hypotenuse
tan X = opposite side / adjacent side
Given is a table which represents the sine, cosine and tangent of two angles in a right angled triangle.
Let x and y be the two angles.
sin x = 0.819, cos x = 0.573 and tan x = 1.428
x = sin⁻¹ (0.819) = cos⁻¹ (0.573) = tan⁻¹ (1.428) = 54.98° ≈ 55°
The sum of the interior angles of a triangle is 180°.
In a right triangle, one angle is already 90°.
Sum of the other two angles = 180° - 90° = 90°.
One angle is got to be 55°.
Then the other angle will be 90° - 55° = 35°.
The sine of 55° is equal to the cosine of 35° and the sine of 35° is equal to the cosine of 55°.
This is because that the opposite side of one angle will be the adjacent side of the other angle.
And the hypotenuse is constant.
sin 55=opposite side/hypotenuse and cos 35=adjacent side/ hypotenuse
Opposite side of 55° and adjacent side of 35° are same.
So they have the same values.
Hence the measures of the angles are 55° and 35°.

Leah rolls two 6-sided number cubes. What is the probability that she rolls a sum equal to 10?
A. 1/11
B. 10/36, or 5/16
C. 2/36, or 1/18
D. 3/36, or 1/12
Answer:
D. 3/36, or 1/12
Step-by-step explanation:
The probability of rolling a sum equal to 10 on two six-sided number cubes is 3/36.
This is because of the 36 total outcomes, only 3 have a sum of 10.
In other words, the probability of rolling a sum equal to 10 is 3 in 36, or 3 out of 36 (3/36).
