Answer:

b)30 boys c)1425 beats

Step-by-step explanation:

Answer:

Step-by-step explanation:

b and g are the number of boys and girls, respectively.

b:g = 3:4

b = 3x, g = 4x

3x+4x = 70

x = 10

There are 30 boys.

:::::

(380 beats)/(4 minutes) = (380/4 beats)/minute = (95 beats)/minute

15 minutes × (95 beats)/minute = 1425 beats

Answer:

x + y = 36 (1)

7x + 4y = 216 (2)

Step-by-step explanation:

Quanrity of Holiday blend = 36 pounds

Cost per pound of the blend = $6.00

Cost of chocolate chips = $7.00 per pound

Cost of pretzels = $4.00 per pound

Let

Pounds of chocolate chips = x

Pounds of pretzels = y

x + y = 36 (1)

7x + 4y = 36 × $6.00

7x + 4y = 216 (2)

The system of equation is

x + y = 36 (1)

7x + 4y = 216 (2)

5.  4:9 or 4/9  

Answer:

50th term

Step-by-step explanation:

Second term, a + d = 3

Tenth term, a + 9d = -13

a + d = 3 (1)

a + 9d = -13 (2)

Subtract (1) from (2) to eliminate a

9d - d = -13 - 3

8d = -16

d = -16/8

d = -2

Substitute d = -2 into (1)

a + d = 3 (1)

a + (-2) = 3

a - 2 = 3

a = 3 + 2

a = 5

Find the term of the sequence that has value -93.

nth term = a + (n -1)d

-93 = 5 + (n - 1) -2

-93 = 5 + (-2n + 2)

-93 = 5 - 2n + 2

-93 = -2n + 7

-93 - 7 = -2n

-100 = -2n

n = -100/-2

n = 50

50th term = -93

Answer:

9.5_<w<9.25

Step-by-step explanation:

Answer:

The third answer is correct

when you plug 1 into the equation

4(1)-9= -5

4(2)-9 = -1

4(3)-9= 3

Step-by-step explanation:

The sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex], option C is correct.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

The given series is -5+(-1)+3+7+11

The sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex]

Now let us check by plugging j values from 1 to 5

When j =1,

4(1)-9= -5

When j =2

4(2)-9 = -1

when j=3

4(3)-9= 3

Hence, the sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex], option C is correct.

Step-by-step explanation:

Corresponding angles are the same angles for both sides.

Example: if a= 12, then b also = 12.

Im positive it's alternate interior because they are both inside on alternative sides

Answer:

1. 25

Step-by-step explanation:

First, you need to place the numbers in ascending order, meaning from smallest to largest.

You calculate the range by taking the largest number and subtract the smallest from it, so in this case: 42-17 = 25

Mean (average), just add the numbers up and divide by how many numbers you have

III. Once you find the Mean and you placed them in order from smallest to largest, you can find this answer

Median (middle) - which number is in the middle so after you place them in order which is in the middle if you have an odd number of marks, but since you have 12 marks then take the 2 center numbers, add them up, and divide by 2, in other words, get the mean of the middle numbers and that will give you the median in this problem

Mode, which number appears the most times repeated

Answer:

i.  25 (range = the difference between the highest and lowest number)

ii. 30.41 (mean = sum of all numbers divided by the how many numbers there are)

iii. 6

iv. 35

v. 35

Answer: r= 1.22

Step-by-step explanation:

Formula for amount with simple interest = [tex]P(1+rt)[/tex]

, where

P= principal value , r= rate of interest , t = time.

Given: P=  $2000, t= 5 years, r= 1.25% = 0.0125

[tex]A=2000(1+0.0125\times5)\\\\=2000(1.0625)=2125[/tex]

Formula to compute compound amount : [tex]P(1+r)^t[/tex]

[tex]=2000(1+r)^5[/tex]

When both have same worth then

[tex]2000(1+r)^5=2125\\\\\\ (1+r)^5=\dfrac{2125}{2000}\\\\\\ (1+r)^5=1.0625[/tex]

taking log on both sides , we get

[tex]5\ln (1+r)=\ln 1.0625\\\\\\ 5\ln (1+r)=0.0606246\\\\\\ \ln (1+r)=0.012125\\\\\\ 1+r=e^{0.005266}\\\\\\ 1+r=1.0122\\\\ r=0.0122\\\\ \\ r=1.22\%[/tex]

Hence, Value of r= 1.22

Answer:

i think this is right $4.80

Step-by-step explanation:

Answer:

52:91

Step-by-step explanation:

To find a ratio value you need to think of it more as two numerators that together equal one whole. 4+7 is 11 so that would be the denominator. If the sum is 143, then we divide by 11 since one number is 4/11s of 143, and the other is 7/11s of 143. 143/11=13

now we multiply both:

4(13)=52

7(13)=91

Check:

91+52=143

52/91 simplifies to 4/7 or 4:7
