There are 4 consecutive integers with a sum of –278. What is the greatest of the 4 integers?
The greatest of the 4 consecutive integers with a sum of -278 is -68
Let n, n + 1, n + 2 and n + 3 be four consecutive integers.
The sum of four consecutive integers is -278.
⇒ n + (n + 1) + (n + 2) + (n + 3) = -278
⇒ n + n + n + n + 1 + 2 + 3 = -278
⇒ 4n + 6 = -278
⇒ 4n = -278 - 6
⇒ 4n = -284
⇒ n = -284/4
⇒ n = -71
So, the consecutive integers would would be:
n = -71
n + 1 = -70
n + 2 = -69
n + 3 = -68
here, the greatest of the 4 integers is -68
Therefore, the greatest of the 4 consecutive integers with a sum of -278 is -68

Dimension of rectangular packet = 25×15×5cm
Volume of cubical box = 75^3
Volume of cubical box = (75 * 75 * 75)cm³ = 421,875 cm³
Volume of rectangular packet = 25×15×5cm = 1875 cm³
Number of rectangular packets required /
421,875 cm³ / 1875 cm³

A triangle has sides of lengths 3.2 cm, 4.8 cm and 3.6 cm. Find the ratio of the lengths of the sides to one another
Answer:3/2
Step-by-step explanation:
i just had this on a test a triangle always equals this
The ratio of the lengths of the sides to one another is 0.8:1.2:0.9.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, a triangle has sides of lengths 3.2 cm, 4.8 cm and 3.6 cm.
The ratio of the lengths is 3.2:4.8:3.6
= 1.6:2.4:1.8
= 0.8:1.2:0.9
Therefore, the ratio of the lengths of the sides to one another is 0.8:1.2:0.9.

Mr kuldeep bought 7½ kg of and Mr Rajesh bought 5¾ kg of rice .who bought more rice and by how much.
Mr. Kuldeep bought more rice than Mr. Rajesh by 1¾ kg, or 1.75 kg more than Mr. Rajesh.
Mr. Kuldeep bought 7½ kg of rice and Mr. Rajesh bought 5¾ kg of rice. To find out who bought more rice and by how much, we need to compare the two quantities.
First, let's convert the mixed numbers into improper fractions:
7½ kg = (7 x 2 + 1)/2 = 15/2 kg
5¾ kg = (5 x 4 + 3)/4 = 23/4 kg
Now, let's compare the two fractions:
15/2 kg > 23/4 kg
Therefore, Mr. Kuldeep bought more rice than Mr. Rajesh.
To find out by how much, we need to subtract the smaller quantity from the larger one:
15/2 kg - 23/4 kg = (30 - 23)/4 kg = 7/4 kg
So, Mr. Kuldeep bought 7/4 kg or 1¾ kg more rice than Mr. Rajesh. In conclusion, Mr. Kuldeep bought more rice than Mr. Rajesh by 1¾ kg.

determine the body mass index of a person 65 inches tall with a weight of 175 pounds
The body mass index of a person 65 inches tall with a weight of 175 pounds is 29.12
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.
The body mass index (BMI) is given by:
BMI = [mass in pounds / (height in inches)²] * 703
Given mass = 175 pounds, height = 65 in, hence:
BMI = [175/65²] * 703 = 29.12

Answer:
A) ∠ABD is a right angle.
E) m∠ABD = 90°
Step-by-step explanation:
just took the test
∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Given that,
Angle A B D is a right angle.
The right angle is a 90-degree angle.
So,
m∠ABD = 90°
Hence "∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles".

The measure of an exterior angle of a triangle is always
A. Greater than its adjacent interior angle.
B. Less than its adjacent interior angle.
C.greater than either remote interior angle.
D.less than either remote interior angle.
A. Greater than its adjacent interior angle. The measure of an exterior angle of a triangle is always C. greater than either remote interior angle.
An exterior angle is formed by extending one side of a triangle. In a triangle, the exterior angle is equal to the sum of the two remote interior angles (the two angles that are not adjacent to the exterior angle).
Therefore, the exterior angle will always be greater than either one of the remote interior angles.
The exterior angle theorem states that when two sides of a triangle are adjacent, the resulting exterior angle is equal to the sum of the degrees of the two interior angles of the triangle. This theorem can be used to find the measure of an unknown angle in a triangle.

44.6% of students do not participate in a sport. To find the percentage of students who do not participate in a sport, we need to use the data from the table.
First, we can calculate the total number of students who participate in a sport by adding the numbers in the "Yes" column to the "Participates in a Sport" row. This gives us a total of 620 + 450 = 1070 students who participate in a sport.
Similarly, we can calculate the total number of students who participate in a club by adding the numbers in the "Yes" column to the "Participates in a Club" row. This gives us a total of 620 + 450 = 1070 students who participate in a club.
To find the total number of students who do not participate in a sport, we need to subtract the number of students who participate in a sport from the total number of students. This gives us a total of 1930 - 1070 = 860 students who do not participate in a sport.
Finally, we can calculate the percentage of students who do not participate in a sport by dividing the number of students who do not participate in a sport by the total number of students and multiplying by 100 to get a percentage.
Percentage of students who do not participate in a sport = (860/1930) x 100% = 44.6%
Therefore, the percentage of students who do not participate in a sport is 44.6%.

Sarah graphs the number of yards the Panthers traveled in the first 7 plays of the football game. What is the meaning of point A i need help now urgent
Answer:
The correct option is;
C. The panthers lost 3 yards on the 3rd play
Step-by-step explanation:
Given that the graph's y-axis represents the number of yards the Panthers traveled, and the x-axis represents the play number, then we have;
The coordinates of the point A are (3, -3) which shows the following;
x-coordinate = Number of play = 3rd play
y-coordinate = Number of yards the Panthers traveled = -3 yards = Loss of 3 yards
The combined meaning of the point A is that the Panthers went back (lost) 3 yards on the 3rd play.
