3.65x3=10.95
5.65x2=11.30
11.30+10.95=22.25
50.00-22.25=27.75

Sari has 3 times as many pencil erasers as Sam. Together, they have 28 erasers. How many erasers does Sari have?

BartSMP [9]

Let

x--------> amount of erasers that Sari has

y--------> amount of erasers that Sam has

we know that

$x=3y$ -------> equation $1$

$x+y=28$ -----> equation $2$

Substitute equation $1$ in equation $2$

$[3y]+y=28\\ 4y=28\\ y=28/4\\ y=7$

find the value of x

$x=3y\\ x=3*7\\ x=21$

therefore

the answer is

Sari has $21$ erasers

The correlation between height and weight among men age 18-74 in the U.S. is about 0.40. Say whether each conclusion below follo

zzz [600]

Answer:

Options a, b, c are correct.

Step-by-step explanation:

First let's see the equation that governs the statement, which is the following:

$r = \frac{cov (x, y)}{\sqrt{var(x) var (y)} }$

Therefore, reading options a, b, c are correct.

Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.

This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.

that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.

Please help me? it is school related i promise

nadya68 [22]

Answer:

$96.25

Step-by-step explanation:

In the morning, this worker was in for a total of 4 hours. Since the wage is $11/hr, we have to multiply 4 by 11.

11 * 4 = 44

In the afternoon, they worked for 4 hours and 45 minutes. Now, we have to multiply 4 3/4 (which is the fraction form of 4 hours and 45 mins) by 11.

11 * 4 3/4 = 52.25

Now, to find the total pay, we add together both the morning and afternoon pays.

44 + 52.25 = 96.25

Therefore, the total pay is $96.25

I hope this helps!! Have a lovely day!! :)

Show step by step......

tankabanditka [31]

Answer:

Step-by-step explanation:

Amount paid for first 100 watches = (65% of 80) *100

$=\frac{65}{100}*80*100\\\\= 65*80\\= 5200$

Amount paid for next 50 watches = (55% of 80) * 50

$= \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200$

Remaining watches = 280 -(100+ 55)

= 280 - 155 = 125

Amount paid for 125 watches = (45% of 80) *125

$= \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500$

Amount received by the watch maker = 5200 + 2200 + 4500

= £ 11900

Evaluate the expression (4x^3)^2 for x=2 A.128 B.512 C.256 D. 1024

julsineya [31]

Answer:

d:) 1024

Step-by-step explanation:

Evaluate (4 x^3)^2 where x = 2:

(4 x^3)^2 = (4×2^3)^2

Multiply each exponent in 4×2^3 by 2:

4^2 (2^3)^2

Multiply exponents. (2^3)^2 = 2^(3×2):

2^(3×2)×4^2

4^2 = 16:

2^(3×2)×16

3×2 = 6:

2^6×16

2^6 = (2^3)^2 = (2×2^2)^2:

(2×2^2)^2 16

2^2 = 4:

(2×4)^2 16

2×4 = 8:

8^2×16

8^2 = 64:

64×16
