The equation for the number of beats per minute is 55 beats per minute

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of beats be = A

Now , the value of A = 220 beats

The total time required for Sam to have 220 beats = 4 minutes

So , the number of beats of Sam in 1 minutes is calculated by

The equation will be

The number of beats of Sam in 1 minutes is = total number of beats  / total time required for Sam to have 220 beats

The number of beats of Sam in 1 minute is = 220 / 4

The number of beats of Sam in 1 minute is = 55 beats per minute

Therefore , Sam would have 55 beats every minute or 55 beats per minute

And for the period of 4 minutes , Sam would have

Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4

Number of beats for 4 minutes = 55 x 4

Number of beats for 4 minutes = 220 beats in 4 minutes

Hence , The equation for the number of beats per minute is 55 beats per minute

Answer:

Step-by-step explanation:

let the first angle be 5x

second be 4x

and third be 1x

as we know that by adding all the sides of triangle we get 180°

therefore  ,

5x+4x+1x=180°

10x=180°

hence ,  

x=18°

first angle - 18*5 = 90°

second angle - 18*4=72°

third angle - 18°

HOPE THIS HELPS YOU !!!

Answer:

18°, 72°, 90°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the parts of the ratio, 5 + 4 + 1 = 10 parts

divide to find the value of one part of the ratio

180° ÷ 10 = 18° ← value of 1 part of the ratio , thus

5 parts = 5 × 18° = 90°

4 parts = 4 × 18° = 72°

Thus the angles of the triangle are 18°, 72° and 90°

Answer:

D, (13, 4.5)

Step-by-step explanation:

(question asked for midpoint so my bad if this isnt what you wanted)

to calculate the median of a vector, you would have to do a simple calculation to get the answer

for the x coordinate, (9 + 17) / 2 would be 13

for the y coordinate, 5 + 4 / 2 would be 4.5

combining those would give you the answer (13, 4.5)

So %44 of your class students chose pizza.

The percentage of the class chose pizza = 44%

"It is a number or ratio that can be expressed as a fraction of 100."

For given example,

Total number of students = 25

the number of students who chose pizza as their favorite food = 11

So, the percentage of the class chose pizza would be,

⇒ (11/25) × 100 = 44%

Answer: what is $9.27 tho????

Answer:

0.19

Step-by-step explanation:

Answer:  D = r*t + r*t   372 3/4 = (63 * 2 3/4) + (57 * 3 1/2)

  OR

D1 + D2 = Total  173 1/4 + 199 1/2 = 372 3/4

D1 = r1 *t1       63 * 2 3/4 = 173 1/4

D2 = r2 * t2      57 * 3 1/2 = 199 1/2

Step-by-step explanation:

The trip is in two segments, so calculate the distance driven in each portion, then add the two distances together to get the total.

Another way to write the expression would be  D = r*t + r*t  

The total distance that Wendy drove to Cleveland will be 372.75 miles.

For the first 2 3/4 hours of her trip, she drove an estimated 63 mph. Then, the distance traveled will be:

= 63 × 2 3/4

= 173.25 miles.

For the second portion of her trip, which took her 3 1/2 hours, she drove at an estimated rate of 57 mph, the distance will be:

= 57 × 3 1/2

= 199.5 miles

The total distance traveled will then be:

= 173.25 miles + 199.5 miles

= 372.75 miles.

y = 6.93

Step-by-step explanation:

Given the Vertex and ficuas of a parabola as :

Vertex (0,0) ; focus(0,2) ; depth = 5 inches

Width of parabolic heater at its widest point :

General equation of a parabola:

4p(x - h) = (y - k)²

(h, k) = Vertex

hence,

h =0 ; k = 0 ; p = 2 ; x = 5

(y - k)² = 4p(x - h)

(y - 0)² = 4*2(6 - 0)

(y-0)(y-0) = 8(6 - 0)

y² = 48 - 0

y² = 48

y = 6.928

y = 6.93
