solve for x 0.61^2x+1=39.2^2x+1​

Answers

Answer 1

If you mean,

[tex]0.61^{2x + 1} = 39[/tex]

then the answer is going to be

[tex]x = \frac{log39}{2log \: 0.61} - \frac{1}{2} [/tex]

but if you mean,

[tex]0.61 ^{2} x + 1[/tex]

then, the answer is going to be, x = 102.123085.

Abishola has an overall GPA of 2.7 over her first three years with 90 credits. She is taking 30 credits her senior and wants her final GPA to be 3.0. Is this possible? If she achieves all A’s her senior year, what will be her final GPA?

(a) 3.025 (b) 3.1 (c) 3.0 (d) 2.94 (e) 2.86 (f) none of the above

Answers

Answer:

(a) 3.025

Step-by-step explanation:

The computation is shown below:

In the case when Abishola acheives all As in the senior year, so the final GPA  Is  

The net GPA is 3

So,

(2.7 × 90 + 30 × x) ÷ 120 = 3

30x = (360 - 2.7 × 90)

x = (360  - 2.7 × 90) ÷ (30)

= 3.9

As she can score till 4 so 3.9 could be possible  

In the case when she score 4 on her final year so her GPA is  

= (2.7 × 90 + 30 × 4) ÷ 120

= 3.025

4. In one semester, Doug and Laura spent a combined 230 hours in the tutoring lab. If Doug
spent 10 hours less than twice the hours Laura did, how many hours did Doug spend in
the lab?

Answers

Answer:

80 hours

Step-by-step explanation:

let d represent doug, let l represent laura

first, set up a system of equations representing the problem:

since doug spent 10 less than twice the hours laura did, and we know that the total amount of hours they spent together is 230:

l=2d+10

d+l=230

then solve:

*first i rearranged the equations so i can solve this system of equations using elimination method*

l-2d=10

l+d=230

*subtract*

3d=240

d=80

so, doug spent 80 hours in the lab

y = -1

so

b = -1

now the slope

m = rise/run

m = 3/2

so

y = 1.5x - 1

Answers

Answer:

60

step-by-step explanation:

Answer: 60

Step-by-step explanation: Basically just multiply the whole number by 2 :)

Whenever you see something times 0.5, just know that its going to be that number times 2 (like another half of that number if you understand)

Why? Because 0.5 is basically like a one half (1/2) and you flip the stuff. since 0.5 is a half, here's a tip. Whenever you're dividing with decimals, use the formula KCF (keep, change, flip) (what my teacher taught me before)
