Answer:
40 feet tall
Step-by-step explanation:
6/2 =3
?/2 =20
*2 *2
? = 40
you do inverse operations because 6 divided by 2 is 3... the ? is the variable for how tall the building is... ? divided by 2 = 20 so you multiply 2 and 20 to get the total height

Step-by-step explanation:
victor are 60 de lei si merge la florarie pentru a-i cumpara mamei sale un buchet de flori. daca ar cumpara 9 garoafe si 4 trandafiri, ar plati 47 de lei. daca ar cumpara doar trandafiri, toti banii i-ar ajunge pentru 12 bucati. insa el cumpara 13 flori (garoafe si trandafiri) si ramane cu 5 lei rest, cate garoafe si cati trandafiri a cumparat victor?
Answer:
Număr de trandafiri = x = 5 trandafiri
Numărul este garoafe = y = 8 garoafe
Step-by-step explanation:
Pasul 1
Să reprezentăm:
Costul garoafelor = c
Costul trandafirilor = r
Victor are 60 de lei și merge la florărie să-i cumpere mamei sale un buchet de flori.
Dacă ar cumpăra 9 garoafe și 4 trandafiri, ar plăti 47 de lei.
Prin urmare,
9c + 4r = 47 ..... Ecuația 1
Dacă ar cumpăra doar trandafiri, toți banii ar fi suficienți pentru 12 bucăți.
Prin urmare,
12 trandafiri = 60 lei
1 trandafir = r lei
Cross Multiply
12r = 60 lei
r = 60 lei / 12
r = 5 lei
1 trandafir costă 5 lei
Înlocuim 5 cu r în ecuația 1
9c + 4 × 5 = 47
9c + 20 = 47
Colectează ca termeni
9c = 47 - 20
9c = 27
c = 27/9
c = 3 lei
Costul unei garoafe este de 3 lei
Pasul 2
Dar cumpără 13 flori (garoafe și trandafiri) și rămâne cu 5 lei rămași,
60 lei - 5 lei = 55 lei
Asta înseamnă că a cheltuit 55 de lei pe 13 flori.
Lasă
Număr de trandafiri = x
Numărul este garoafe = y
x + y = 13 ......... Ecuația 1
x = 13 - y
Din moment ce, Costul unei garoafe = 3 lei și 1 trandafir = 5 lei
3x + 5y = 55 ...... Ecuația 2
Înlocuim 13 - y cu x în ecuația 2
3x + 5y = 55
3 (13 - y) + 5y = 55
39 - 3y + 5y = 55
Colectează ca termeni
- 3y + 5y = 55 - 39
2y = 16
y = 16/2
y = 8
Rezolvarea pentru x
x = 13 - y
x = 13 - 8
x = 5
Prin urmare:
Număr de trandafiri = x = 5 trandafiri
Numărul este garoafe = y = 8 garoafe

Find the measure of each interior angle and each exterior angle of a regular 90-gon.
Answer:
Interior angle
176 degrees
Exterior
4 degrees
Step-by-step explanation:
Exterior angle
For any polygon, the measure of the total exterior angle is 360
To get the individual exterior angle, we divide the total by n, which is the number of sides, 90 in this case
We have this as;
360/90 = 4
Interior
To get the measure of each interior angle, we use the formula below;
[(n-2)180]/n
n in this case is 90
So we have
[(90-2)180]/90
= (88 * 180)/90
= 2 * 88 = 176

x = 21
angle ABE = 3(21)-8 = 55
The probability of rolling a 2 on a number cube is 1/6 . If you were to roll the
cube 30 times, you would expect to get a 2 around 5 times (1/6 · 30 = 5).
You simulate 30 rolls. How many 2s would make you question your model?
A. 14
B. 5
C. 2.
D. 8
Answer: a
Step-by-step explanation:
If a cube is rolled by 30 times then 5 times 2s will make the question the model.
What is probability?Probability is the occurrence of any event or how likely an event can happen.
Mathematically probability = the number of desired outputs by the number of the possible outcomes.
In the number cube, there are six faces above each of them written one to six later.
The probability of getting 2 at once time will be 1/6 since the number of desired output is only one and possible outcomes are six.
Mathematically(Theoretically) if we roll the cube 30 times then the number of 2s will be 1/6 × 30 = 5 times.
If experimentally if we roll dice and the number of 2s came 5 times then our question will become a model.
So by 5 times, 2s will make the question model.

Answer:
He'll pay $110.25
Step-by-step explanation:
To find the area, we divide the shape into two parts at approximately the middle line. The top shape is a trapezoid of base length 7 feet and height 6 feet, while the bottom shape is a parallelogram with one side equal to 4 feet.
Area of trapezoid = (7 + 4)/2 x 6
Area of trapezoid = 33 sq ft
Area of parallelogram = 4 x 4
Area of parallelogram = 16 sq ft
Total area = 49 sq ft
Cost = 2.25 x 49
Cost = $110.25

What is the equation of the line that passes through the point (-5,5) and has a
slope of -1?
Answer:
y = - x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 1 , then
y = - x + c ← is the partial equation
To find c substitute (- 5, 5 ) into the partial equation
5 = 5 + c ⇒ c = 5 - 5 = 0
y = - x ← equation of line
