a woman is looking for a bigger square office. she finds an office twice the area of her square office. if the perimeter is 88ft
UNO [17]

Answer:

Option C is the correct answer.

Step-by-step explanation:

Perimeter of current office = 88 ft

We have perimeter = 4a , where a is the side of square.

Equating

4a = 88

a = 22 sqft

Area of current office = a x a = 22 x 22 = 484 square feet.

Area of new office is twice the area of current office.

Area of new office = 2 x 484 = 968 square feet.

Option C is the correct answer.

Order the group of quadratic functions from widest to narrowest graph. y = 6x2, y = −4.5x2, y = −x2
melamori03 [73]
To solve this problem you must keep on mind the following information: By definition, a quadratic function has the following form: 
 y=ax^{2}+bx+c

 Where a
 is the leading coefficient.
 If the leading coeficient is closer to zero, the parabola is widest,if it has a larger positive or negative value, the parabola is narrowest.
 Therefore, by knowing the information above, you have that the answer is:
 y=- x^{2}  \\ y=-4.5 x^{2}  \\ y=6 x^{2}

A study was conducted on the effects of long-term marriage (more than 10 years). Researchers gathered data from a random sample
True [87]

Answer:

The correct option is;

We cannot infer a cause and effect relationship because the multiple variables were included

Step-by-step explanation:

The criteria required in order to establish a cause and effect relationship includes the following;

1) There must be a temporal precedence between the cause and the effect such that the cause must take place before the effect

In the question, it is not clearly stated weather there was a divorce (the likely cause) takes place before the event

2) In the vent that the cause occurs, the effect must occur

Therefore, all those who are not married are expected to be deceased for there to be a cause and effect relationship

3) The cause and effect relationship must not be explicable by other factors

In the question, it is stated that those who were married were more likely to be active physically, maintain an healthy weight and were nonsmokers, which are factors that contribute to longevity.

Alex is 1.6 m tall and Noah is 1.5 times as tall as Alex. How much taller is Noah in centimeters?​
nika2105 [10]

Answer:

80 centimeters taller

Step-by-step explanation:

First, convert Alex's height from meters to centimeters by multiplying by 100 because there are 100 centimeters in one meter to get 160 centimeters. Now multiply 160 centimeters by 1.5 to get Noah's height, 240 centimeters. Finally, since we need to find their difference in height, subtract Alex's height of 160 centimeters from Noah's height of 240 to get 80 centimeters.

nevsk [136]

Answer:

GCF

Step-by-step explanation:

Each row will have the same number of plants.  So we want to know what's the biggest number we can divide 45, 81, and 63 by.  That means we need to find the greatest common factor.  In this case, it's 9.  Each row can have at most 9 seeds.
