Answer: Janey has $115, and Teresa has $230.
Step-by-step explanation:
Set x be the money that Janey have, then Teresa have 2x.
x + 2x = 345
3x = 345
x= $115
2x= 2(115)= $230
N 1846 the depth of the river was 5 feet deep. In 1847 it dropped to 3.2 feet. This year, 1848, it rose to 6.6 feet. Find the percent change in river depth
Answer:
40.4%
Step-by-step explanation:
Given data
Initial depth= 5feet
Final depth= 5-3.2+6.6= 8.4feet
Hence the percent change
% change= FInal-initial/final*100
% change= 8.4-5/8.4*100
% change= 3.4/8.4*100
% change= 0.404*100
% change=40.4%
Hence the percent change is 40.4%
Percentage change between two measurement is the proportion of
change between the measurement expressed as a percentage.
The percentage change in the river depth in in 1848 is 106.25%
Reasons:
The given parameters are;
The depth of the river in the year 1846 = 5 feet
In the year 1847, the depth = 3.2 feet
In 1848 the depth = 6.6 feet
[tex]\displaystyle Percentage \ change = \mathbf{ \frac{Current \ depth - Previous \ depth}{Previous \ depth}}[/tex]
Which gives;
[tex]\displaystyle Percentage \ change = \frac{6.6 -3.2}{3.2} \times 100 = \mathbf{106.25 \%}[/tex]
The percentage change in the river depth in the current period = 106.25%

This relationship is y = 3x.
Because y is always x multiplied by 3.
Thus this relationship is the only proportional one because it is in the form y = kx, where k is the constant of proportionality.
The relationship is also known as direct variation because it goes through (0,0) has a constant variation, and is a linear relationship.

The radius of a circle is 4 centimeters. What is the angle measure of an arc bounding a sector with area 2 square centimeters?
Answer:
Measure of the arc = 14.32°
Step-by-step explanation:
Radius of a circle = 4 cm²
Area of the circle = πr²
Here, r = radius of the circle
Area of the circle = π(4)²
= 16π cm²
= 50.265 cm²
Since, area of a sector = [tex]\frac{\theta}{360}(\text{Area of the circle})[/tex]
Here, θ = Central angle subtended by the arc Or measure of arc
Area of the sector given as 2 cm²
2 = [tex]\frac{\theta}{360}(50.265)[/tex]
θ = 14.32°
Therefore, measure of the arc = 14.32°.

The momentum of a variable is represented by the rate of change. The rate of change for the situation is 3 miles per hour.
What is the rate of change?The momentum of a variable is represented by the rate of change, which is used to quantitatively express the percentage change in value over a specific period of time.
Given the distance covered in one hour is 3 miles, while the distance covered in 2 hours is 6 miles. In the given case, the rate of change for the situation, therefore,
Rate of change = (6miles-3miles)/(2hours-1hour) = 3miles/hour.
Hence, the rate of change for the situation is 3 miles per hour.

Gravity pulls the metal down at 10 N, but the metal pieces RISES! At least how much force is needed to make it move upward?
Answer: Greater than 10 N
Step-by-step explanation:
Given
Gravity force on metal is 10 N
But the metal piece is rising i.e. there must be an upward force greater than 10 N
Suppose the force is F
So, we can write
[tex]\Rightarrow F>10\ N[/tex]
Any force greater than 10 N is sufficient for the metal to move upwards
The greater the amount of force faster will be the movement

Three teachers buy prizes to put in the prize bin at school. Mrs. Maiers spends $7.68 on stickers. Mr. Lang spends $11.52 on balloons. Mrs. Connor spends $17.64 on pencils.
Answer: $12.28
Step-by-step explanation:
Here's the complete question:
Three teachers bought prizes to put in a bin at school. Mrs. Maier spent $7.68 on stickers. Mr. Lang spent $11.52 on balloons. Mrs. Connor spent $17.64 on pencils. The teachers divided the cost evenly. How much did each teacher pay?
Cost of stickers = $7.68
Cost of balloons = $11.52
Cost of pencils = $17.64
Total spent = $7.68 + $11.52 + $17.64 = $36.84
The amount that each teacher will pay when the total cost is evenly shared will be:
= $36.84 / 3
= $12.28

ZABC is bisected by BD. If m DBC = 65°,
then m ZABC = [?]°
Enter
Answer:
m∠ABC = 130°
Step-by-step explanation:
BD is the angle bisector of angle ABC .
Therefore, ∠ABD ≅ ∠DBC
Measure of angle DBC = 65°
Therefore, m∠ABD = m∠DBC = 65°
m∠ABC = m∠ABD + m∠DBC
= 65° + 65°
= 130°
