The percent of the total calories in each brownie comes from fat will be;
⇒ 35.84%
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The wrapper said each brownie was 451 calories, and had 252 calories of fat.
Now,
Since, The wrapper said each brownie was 451 calories, and had 252
calories of fat.
Hence, Total calories = 451 + 252
= 703 calories
And, The calories of fat = 252 calories
Thus, The percent of the total calories in each brownie comes from fat is find as;
⇒ Percent = 252/703 × 100
= 35.84%
Therefore, The percent = 35.84%

The expression that shows how many sweatshirts were not adult sizes is s - 19 .
Given :
the lacrosse team sold s team booster sweatshirts, and 19 of them were adult sizes.
Expression :
An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.
Expression = number of sold sweatshirts - number of adult sizes.
= s - 19.
This gives the number of sweatshirts that are not adult sizes
if s = 25
then not adult sizes sweatshirts = s - 19
= 25 - 19

Let point A be (2,7) and point B be (-6,-3). What point is on the segment connecting A and B such that the distance from the point to B is 4 times the distance from the point to A?
Answer:
The point on the segment connecting A and B that is 4 times as far from B as it is from A is (-8, 8).
Answer:
or the distance to be 4 times the distance from B as A the segment must be divided into (4+1) = 5 segments
so we want the point that is 1/5 of the way from A to B
x from A to B is 2 to - 6 = -8 units 1/5 * -8 + 2 = 0.4
y from A to B is 7 to -3 = -10 units 1/5 * -10 + 7 = 5

The ratio r:h is 5:8 and the ratio h:u is 4:7. Work out the ratio r:h:u in its simplest form
The simplest form of the ratio r:h:u is 5 : 8 : 14.
What is the ratio?
A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.
We have,
r : h = 5 : 8 .........(i)
h : u = 4:7 ........(ii)
Multiplying the (i) and (ii) by numbers that will make 'h' have the same value in the ratios
Multiplying (i) by 1
(r : h)*1 = (5 : 8)*1
= r : h = 5 : 8
Multiplying (ii) by 2
(h : u)*2 = (4:7) *2
= 8 : 14
the ratio r : h : u in the simplest form = 5 : 8 : 14.
Hence, the simplest form of the ratio r:h:u is 5 : 8 : 14.

a car is traveling at 50 mph due south at a point 1 mile north of an intersection. a police car is traveling at 40 mph due west at a point 1 mile east of the same intersection. at that instant, the radar in the police car measures the rate at which the distance between the two cars is changing. what does the radar gun register?
If a car is traveling at 50 mph due south at a point 1 mile north of an intersection. the radar gun register at -62.6 mph.
What is distance?Distance can be defined as how far an object is from another object.
Distance of the first car north of the intersection point =y
Distance of the police car west of the intersection =x
Distance between the cars =s
s² =x² +y²
x=1.4 miles or 0.25 miles
y =1/2 miles or 0.50 miles
Pythagoreans theorem
Distance between cars
s =√x²+y²
s=√(0.25 miles)² +(0.50 miles)²
s =0.559 miles
Hence,
ds/dt = [0.25 miles/ 0.559 miles (-40 mph)] + [0.50 miles/0.559 miles (-50 mph)
ds/dt = -17.89 + -44.7
ds/dt = - 62.59mph
ds/dt =- 62.6 mph (Approximately)

A plane angle is measured in degrees, with the letter ° typically used to indicate that one full rotation is equal to 360 degrees. Although it is not a SI unit—the radian is the SI unit of angular measure—it is mentioned as an accepted unit in the SI brochure.
Angles are measured in terms of radians. Angles are measured using the degree and radian units. In calculus and the majority of other branches of mathematics, angles are typically or generally measured in radians.

A. how fast was she going in miles per hour?
B. At that rate, how long will it take her to go 4.5 miles?
The cyclist takes 0.36 hours to travel 4.5 miles.
What is distance?The actual length covered by the body is defined as distance travelled, whereas displacement is the straight path between the initial and final points.The imperial and customary systems use the unit miles per hour (symbol: mph) to measure speed. It represents the number of statute miles traveled in one hour.Here given that,
The distance travelled by the cyclist 3.75 miles.
Time = 0.3 hour
Distance / Time = Speed
By substituting,
3.75 / 0.3
= 12.5 miles per hour is the speed.
2) Distance = 4.5 miles, speed = 12.5 miles per hour.
Distance / Speed = Time
Time = 4.5 / 12.5
