Step-by-step explanation:

Answer:

A- 16 songs a day

B- 32 songs in the weekend

Step-by-step explanation:

A- if she songs "jingle bells" 5 times, the sings"silver bells" twice as many times, that would just be like multiplying  5 x 2, which equals 10, then add the 5 times she sings jingle bells, that would be 15. then she sings "silent night" one time which adds on to the other songs to get 16 songs a day

B- the weekend has 2 days in it so you would just multiply 16 x 2 which gives you 32

Answer:

33

Step-by-step explanation:

.6 * 55 = 33

Answer:

$33

Step-by-step explanation:

Cross multiply 60/100=x/55

=>60(55)=100x

=>3300=100x

divide both sides by 100 to get x by itself=> 33=x

LOVE YOUR PFP!!!

Step-by-step explanation:

Answer:

1. Two less than 3/2 of a number (x) is no more than 5 1/2 is last

2. Seven subtracted from 4 times a number (x) is more than 13 is second

3. Four added to 3 times a number (x) is less than 19 is third

4.The sum of two times a number (x) and -2 is at least 8 is first

Step-by-step explanation:

got it right

Expand the binomials, then simplify, then invoke the Pythagorean identity:

(p sin(B) - r cos(B))² + (r sin(B) + p cos(B))²

= (p² sin²(B) - 2pr sin(B) cos(B) + r ² cos²(B)) + (r ² sin²(B) + 2pr sin(B) cos(B) + p² cos²(B))

= p² (sin²(B) + cos²(B)) + r ² (cos²(B) + sin²(B))

= p² + r ²

Answer: 50 miles per hour

Step-by-step explanation:

Find out the length of the normal route.

Distance = Speed * time

= 48 * 40/60

= 32 miles

The detour is 8 miles longer so the length is;

= 32 + 8

= 40 miles

What speed should he travel at to make it in 48 minutes. Remember speed is in miles per hours.

Speed = Distance/ time

= 40 / (48/60)

= 50 miles per hour

Answer:

50 miles per hour :)

Step-by-step explanation:

Distance = Speed * time = 48 * 40/60 = 32 miles

Detour is 8 miles longer so = 32 + 8 = 40 miles

In 48 minutes. Remember speed is in miles per hours.

Speed = Distance/ time

50MPH= 50 miles per hour

Answer:

63 books in each boxes

1 book left which need a box

Step-by-step explanation:

James has 568 books

He plans to put them into 9 boxes

Therefore the number of books n each boxes can be calculated as follows

= 568/9

63 remainder 1

Hence there would be 63 books in each boxes and 1 book would be left which need another box

Answer:

(1). E ; (2). C ; (3). H ; (4) A ;

Step-by-step explanation:

(1). m = [tex]\frac{1}{2}[/tex]

(2). m = 2

(3). m = - [tex]\frac{1}{2}[/tex]

(4). m = - 2

Answer:

ECHA

Step-by-step explanation:

1.) E

m = 1/2

2.) C

y2 - y1/x2 - x1 = m

-4 - (-8)/3 - 1 = m

8 - 4/3 - 1 = m

4/2 = m

m = 2

3.) H

y2 - y1/x2 - x1 = m

-3 - (-6)/-4 - 2 = m

6 - 3/-6 = m

3/-6 = m

-1/2 = m

4.) A

m = -2

Answer:

The Right Answer is  X=10

Answer:

-8, -3, 2 ad 7

Step-by-step explanation:

This graph shown is a polynomial function. The solution is the point where the curves cuts the x axis. From the diagram we can see that the curves cuts the x axis at four points.

The points are at x1 = -8, x2 = -3, x3 = 2 and x4 = 7

Hence the real solutions to the function f(x) = 0 are -8, -3, 2 ad 7

Step-by-step explanation:

x=2, x+2=4 I think that is the right answer

The condition which satisfy the congruency of the given triangle is

BC≈QR.

Two triangles are said to be congruent if all the corresponding sides are equal and all the corresponding angles are equal. The symbol of congruency is '≅'

here, we have,

from the given information, we get,

To show that triangle ABC ≈ triangle PQR by SSS,

In this type of congruency, all the sides of the triangle ABC is equivalent to the all the sides of the triangle PQR.

Given, AC≅PR, AB≅PQ.

The another one condition is BC≅QR.

Hence, the condition which satisfy the congruency of the given triangle is BC≈QR.

Answer:

[tex]25x^{2} - 9y^{2}[/tex]

Step-by-step explanation:

5x*5x=[tex]25x^{2}[/tex]

3y*3y= [tex]9y^{2}[/tex]

The proportionality is 0.45, then the equation is C = 0.45 n. The number of peppers you buy for $20 will be 44.44. Then the table is completed below.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Let 'C' be the cost and 'n' be the number of peppers. Then the proportionality is given as,

C ∝ kn

At n = 5, the cost C = 2.25, then we have

2.25 = k (5)

k = 2.25 / 5

k = 0.45

Then the equation is given as,

C = 0.45 n

The number of peppers you buy for $20 will be given as,

20 = 0.45 n

n = 44.44

Then the table is completed below.

Number of peppers             Cost

              1                              $0.45

             2                              $0.90

             3                              $1.35

             4                              $1.80

             5                              $2.25

            10                              $4.50

            15                              $6.75

           20                              $9

          100                              $45
