Answers

Answer 1

Answer: $(0.100-0.15)x=76.49$

$0.85x=76.49$

$x= (76.49)/(0.85)$

$x=89.99$

$$89.99$

A) 21
B) 27
C) 31
D) 34

Answers

Answer: A) 21

Step-by-step explanation:

From the given figure, we can see that angles $64^(\circ)$ and $(3x+1)^(\circ)$ are vertically opposite angles.

Since, vertically opposite angles are equal, therefore we have

$64^(\circ)=(3x+1)^(\circ)\n\n\Rightarrow64=3x+1\n\n\text{Subtract 1 on both sides, we get}\n\n\Rightarrow3x=63\n\n\text{Divide 3 on both sides, we get}\n\n\Rightarrow x=21$

Hence, the value of x = 21.

The answer is a, 21. 21x3 is 63. 63 + 1 = 64.

The ratio of miles to hours in activity 1 is 14;2 which can be reduced to 7:1 How is simplifying the ratio similar to division??

Answers

It is similar to division because when you reduce 14:2 you just divide 14 by 2 and 2 by 2

At one store Julia save $10 with the coupon for 20% off her total purchase at another store the $24 she spent on books is 40% of her total bill how much did Julia spend it all at the two stores

Answers

At the first store, Julia spent 50 dollars. Since 20 percent is 100 divided by 5, you multiply the 10 dollars by 5 to get 50 dollars.

At the second store, Julia spent. Since 12 dollars is 20 percent, multiply 12 dollars by 5 to get 60 dollars.

50+60= 110. Julia spent 110 dollars altogether.

Which of the following represents exponential growth? $y = 2x + 5$
$y - x = 4$
$x = 3$
$y = 5 * 2^(x)$

Answers

Answer:

y = 5 × $2^(x)$

Step-by-step explanation:

Exponential growth equations are usually in the form y = a × $b^(x)$ .

So, y = 5 × $2^(x)$ is the best fit for that format.

Have a great day!

The exponential growth:

$y=a\cdot b^x$

Therfore your answer is $y=5*2^x$

--------------------------------------------------------

y = 2x + 5 it's a linear function in slope-intercept form

y - x = 4 → -x + y = 4 it's a linear function in standard form

x = 3 it's a vertical line

To find the volume of a sphere:
$(4)/(3) *3.14*R^3$

3.14≈π

Now since its telling us to use π, then we do our formula by multiplying by π.

π=3.14 (Approximate amount)

So:

$4/3*3.14*9^3=3052.08$

So you are correct.

When Radius=9, you plug in for R. :)

Yes your answer is correct.
9 = R , for radious
Sphere Formula = s = 4, Pi r powered by 2 , volume below :

Volume of a sphere = V = (4/3)x(3.14)x(r^3)

now we have to multiply by pi = 3.14 which gets us
3052.08 | in powered by 3

so again yes you were right

(9x100)+ (8x10)= 7(1/1000) as a decimal

Answers

71.1000 that must be the answer

Final answer:

The given equation (9x100) + (8x10) = 7(1/1000) as a decimal is 980 = 0.007.

Explanation:

To convert the given expression into a decimal, we first need to evaluate the arithmetic expression on the left-hand side: (9x100) + (8x10). This can be done by simplifying the multiplication operations first, then performing the addition. Multiplying 9 by 100 gives us 900, and multiplying 8 by 10 gives us 80. Adding these two results together, we get 980. So the left-hand side of the equation becomes 980.

Next, let's convert the right-hand side of the equation, 7(1/1000), into a decimal. To do this, we need to divide 1 by 1000. Dividing 1 by 1000 gives us the decimal 0.001. Finally, we multiply this decimal by 7, giving us 0.007.

Therefore, the given equation (9x100) + (8x10) = 7(1/1000) as a decimal is 980 = 0.007.
