Hi there.

The answer is definitely "D" because on the graph it shows there are only 29 students that did the test.

Hi Niceygraham200ov46fq,

Your answer would be D. This is because of the fact that there is clearly only 29 people on this. Therefore, your answer will be 29.

If b/a=c/b=d/c=2/3, find the value of a:b:c:d

leva [86]

Answer:

the ratio would be 6.75:4.5:3:2

Step-by-step explanation:

replace d and c with

d=2 and c=3

Then using proportion multiplication, you will find that b is 4.5

now replace all b with 4.5.

Then again using proportion multiplication, you will get a is 6.75.

Plug in a, b, c, d in the ratio and you get 6.75:4.5:3:2

Help me solve please! The math club has 57 members who are in sixth or seventh grades. There are twice as many sixth graders as

saul85 [17]

We know there is 57 members are in the math club and there is twice as many sixth grades than the seventh. To find out how many sixth graders are in the club, we do:

x = seventh graders
2x = sixth graders

2x + x = 3x

57=3x
57 ÷ 3 = 3x ÷3
19 = x

So there is 19 seventh graders and 19×2= 38 sixth graders

Solve 3x + 2 = 15 for x using the change of base formula log base b of y equals log y over log b. −1.594 0.465 2.406 4.465

disa [49]

Answer:

The value in 3x + 2 = 15 for x using the change of base formula is 0.465 approximately and second option is correct one.

Solution:

Given, expression is $3^{(x+2)}=15$
