Answer:
428
Step-by-step explanation:
Its says out of 60, 29 of them play sports
so we want to use proportions to solve for how many would play if there were 887 kids
[tex]\frac{60}{29} =2.068965517\\\frac{887}{2.068965517} = 428[/tex]
thus meaning that out of 887 kids 428 of them would play sports

Answer:
11). x = 25.8°
12). x = 67.3°
Step-by-step explanation:
11). By using sine rule in the given triangle,
cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(x) = [tex]\frac{27}{30}[/tex]
x = [tex]\text{cos}^{-1}(\frac{9}{10} )[/tex]
x = 25.84
x ≈ 25.8°
12). By applying tangent rule in the given triangle,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{43}{18}[/tex]
x = [tex]\text{tan}^{-1}(\frac{43}{18} )[/tex]
x = 67.29°
x ≈ 67.3°

PLS HELP
Answer:
x=42°
y=64°
z=68°
Step-by-step explanation:
Consider the triangle towards the right with 90° and 48° marked. The other angles must equal 42° (angles in a triangle add to 180, 42+48+90=180). This 42° angle is vertically opposite x, so x=42°.
The triangle that contains z also contains the angle 22° and 90° (because it is on a straight line with another 90° angle and the angles along a straight line add up to 180 (90+90=180)). Since the angles in a triangle add to 180, z=68°. (68+22+90=180)
The angles z, 48° and y lie along a straight line. Since the angles along a straight line equal 180 and since we know that z=68°, we can say y=64° (68+64+48=180)
Answer:
Solve for x: (use triangle sum theorem)
48+90+x=180
x = 42 (vertical angles)
Solve for y: (Find z first, then use triangle sum theorem)
68+48+z=180
y = 64
Solve for z: (triangle sum theorem)
22+90+z=180
z=68

Find the surface area of the composite figure.
Answer:
644 cm³
Step-by-step explanation:
Surface area of the composite figure = (surface area of the upper cuboid - base area of upper cuboid) + (surface area of the lower cuboid - base area of the upper cuboid)
✔️Surface area of upper cuboid = 2(LW + LH + WH)
L = 3
W = 3
H = 8
Surface area of upper cuboid = 2(3*3 + 3*8 + 3*8) = 2(9 + 24 + 24) = 114 cm²
✔️Surface area of Surface area of lower cuboid = 2(LW + LH + WH)
L = 12
W = 10
H = 7
Surface area of lower cuboid = 2(12*10 + 12*7 + 10*7) = 2(120 + 84 + 70) = 548 cm²
✔️Base area of upper cuboid = L*W
L = 3
W = 3
Base area = 3*3 = 9 cm²
✅Surface area of the composite figure = (114 - 9) + (548 - 9) = 105 + 539 = 644 cm³

A computer program found that the line c=2t−89c=2t−89c=2t−89 is a good fit for the data. Use this equation to predict how many cups of lemonade Lin might sell on a day when the high temperature is 74 degrees.
Answer:
58cups
Step-by-step explanation:
Given the equation for the line as c = 2t - 89
If the temperature is 74 degrees, then we can find the number of cups at this temperature;
Substitute t = 74 unti the expression
x = 2(74) - 89
c = 147 - 89
c = 58cups
Hence the number of cups of lemonade is 58cups

Answer:
pi
Step-by-step explanation:
to convert angles to radians you must multiply the angle measurement by the formula pi/180
180 x pi/180
the 180s cancel out and you are left with pi
Answer:
3.14159 Radian
Step-by-step explanation:
3.142rad × 180/π = 180°

Use the image to the right to answer the questions:
a. What theorems would/could you use to find x?
b. Find the value of x.
Thank you so much in advance! :)
Answer:
a. Linear pair theorem
b. x = 40
Step-by-step explanation:
a. You can use linear pair theorem. That is, two angles on a straight line are supplementary. They sum up to 180°
b. Thus:
x + (4x - 20) = 180°
x + 4x - 20 = 180
5x - 20 = 180
5x = 180 + 20
5x = 200
x = 200/5
x = 40

Answer:
B. x = 7; AB = 9, AC = 12
Step-by-step explanation:
12/4 = (x + 2)/(x - 4) (similar triangles theorem)
3 = (x + 2)/(x - 4)
Cross multiply
3(x - 4) = (x + 2)
3x - 12 = x + 2
Collect like terms
3x - x = 12 + 2
2x = 14
x = 14/2
x = 7
✔️AB = x + 2 = 7 + 2
AB = 9
✔️AC = (x + 2) + (x - 4) = (7 + 2) + (7 - 4)
AC = 9 + 3
AC = 12
