Step-by-step explanation:

I will apply equivalent fractions here or enlargement is also allowed

let find the factor,k

3/0.25=k

12=k

to get x

x/0.5=12

x=12*0.5

x=6cm

Answer: 325 students

Step-by-step explanation:

13 students were absent and this is 4% of the school's total enrollment.

If 13 students represent 4% of the students, assume that x represents 100% of the students:

4% * x = 13

0.04x = 13

x = 13/0.04

x = 325 students

There are 325 students in this school.

The answer selected is correct

Step-by-step explanation:

Answer:

785

Step-by-step explanation:

flowers needed to surround the garden = circumference of the garden / space

circumference of a circle = 2nr

n = 3.14

r = radius

The radius is in ft and the space is in inches. i would convert the ft to inches to aid comparability

1ft = 12 inches

125 x 3 = 375

2 x 3.14 x 375 = 2355

flowers needed = 2355 / 3 = 785

Answer:

∠ 1 = 102°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ 1 is an exterior angle of the triangle , then

∠ 1 = 33° + 69° = 102°

Answer:

102

Step-by-step explanation:

exterior angle rule:

an exterior angle of a triangle is equal to the two opposite interior angles

so m1= sum of opposite interior angles (69 and 33)

69+33=102

so m1 = 102

Answer:

T=116

Step-by-step explanation:

That is a 90 degree angle and a 26 degree angle, so 26+90=116. 360 is the total degrees in all, so 360-116=224. t degrees is 116.

Step-by-step explanation:

t = 90° + 26° { Being vertically opposite angles }

t = 116 °

Answer:

to find the value of x have to know that they would all add up to 180 degrees. so subtract 98 from 180. then you would have to find the angel of the part on the left.

Step-by-step explanation:

Answer:

X = 41

Step-by-step explanation:

this triangle is isosceles triangle, so

X + X + 98 = 180 ( being triangle)

2X + 98 = 180

2X = 82

therefore : X = 41

Answer:

57in^2

Step-by-step explanation:

Divide the shape into 2 recatngles.

Imagine a line cuts away a rectangle of length 12in by width 4in. from a square  of length (12-9)in. and width (7-4)in

This gives you 2 different shapes

Find their area

Rectangle one has an area of = 12in x 4in = 48in^2

Square has an area of = (12-9) in x (7-4) in = 3x 3 inch = 9in.^2

Find their sum to find the area of the whole compound shape:

48+9 = 57in^2

Hope this helps

Answer:

0 i think

Step-by-step explanation:

Answer:

The answer is -69,420 ! 69,420 - 69,420 = 0. next you multiply it and its 0 again then you add it 69,420 then subtract it equals 0 then subtract again it equals -69,420 then multiply it equals -69,420 then you have to add 69,420 it equals 0 again then you subtracted 69,420 and that means its -69,420!

Answer:

2  1/2

Step-by-step explanation:

30/ (5+7)

solve using system of operations

PEMDAS

Parenthesis

Exponent

Multiplication/Division

Addition/Subtraction

30/(5+7)

parenthesis first so

5+7 = 12

30/12

then division

30/12= 2  6/12

6/12 can be simplified by 6 so

6/6 = 1 and 12/6 = 2

So your answer would be 2  1/2

The quotient of 30 and the sum of 5 and 7 is 2.5

From the question we are to write the information as an expression:

Simplify the result

[tex]\frac{30}{5+7} =\frac{30}{12} = 2.5[/tex]

Hence  the quotient of 30 and the sum of 5 and 7 is 2.5

Answer:

[tex]a_{n}[/tex] = 3n + 77

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 80 and d = a₂ - a₁ = 83 - 80 = 3 , then

[tex]a_{n}[/tex] = 80 + 3(n - 1) = 80 + 3n - 3 = 3n + 77
