Answer:

2)16.5

Step-by-step explanation:

step1:v/2.2 -0.1=7.4

add 0.1 on both sides

step2:v/2.2=7.5

multiply by 2.2 on both sides

step3:v=16.5

2) v/2.2 - 0.1 = 7.4

v/2.2 = 7.4 + 0.1

v /2.2 = 7.5

v = 7.5 * 2.2

v = 16.5

6) -14.3 = -1.4 -3d

-14.3 + 1.4 = -3d

d= 4.3

Answers

-- As the line moves from left to right, it rises. So you know that
its slope is positive.
(All 4 choices have positive slopes, so that doesn't help.)

-- From the place where the line crosses the x-axis to the place
where it crosses the y-axis, it moves 2 units forward and also
rises 2 units. So you know that its slope is (2/2) = 1 .
(A. and C. both have slopes of 2, so it can't be either of those.)
(B.and D. both have slopes of 1,so it could be either of those.)

-- The line does not go through the origin. So you know that
its y-intercept is not zero.
(A. has no y-intercept, so that can't be it.)

-- The line crosses the y-axis at y=2, so you know that its y-intercept is 2 .
(B. has y-intercept of -2, so that can't be it.)
(C. and D. both have y-intercept of 2, so it's one of those.)
(But the slope has to be 1, and C. has slope of 2.)
(So it must be D.)

The answer is D. The rise over run is 2/2 which is y=x and it is shifted up 2 on the x axis so D

3 to the 10th power = 3 to the 7th power times x to the 3rd power (solve for x)

Answers

Answer:

Step-by-step explanation:

Rewriting this sentence as an algebraic equation, we get:

3^10 = 3^7 * x^3.

Dividing both sides by 3^7 simplifies the problem:

3^3 = x^3

Here this x corresponds to the 3 in 3^3. Thus, the solution is x = 3.

Final answer:

Using exponent rules and logarithms, the given equation can be simplified and solved to find that x equals 3.

Explanation:

The subject of the question falls into the field of Mathematics, specifically exponent rules, which are used in High School level algebra. In the mathematics problem provided ('3 to the 10th power = 3 to the 7th power times x to the 3rd power'), we need to solve for x using the knowledge of exponents.

First, it's helpful to know that when two expressions with the same base (in this case, 3) are set equal to each other, their exponents must also be equal. Since we know that 3 to the 7th power times x to the 3rd power equals 3 to the 10th power, we can break this down further. This leads to the equation 7 + 3log(x) = 10, where 'log' represents the logarithm.

By simplifying the equation, we get 3log(x) = 10-7, so 3log(x) = 3. Therefore, log(x)=3/3, hence log(x)=1. If we apply anti logarithm on both sides, we'll find that x = 3 to the power of 1, so x = 3. In other words, 3 to the 3rd power will equal3 to the 10th power divided by 3 to the 7th power. Hence, the value of x is 3.

#SPJ3

Beulah used 3/5 pounds of dough, 3/4 pound of sugar, & 2/3 pounds of sprinkles to make donuts. How many pounds of donuts did Beulah make?

Answers

Number of pounds of dough used = 3/5 pounds.

Number of pounds of sugar used = 3/4 pounds

Number of pounds of sprinkles used = 2/3 pounds.

Total number of pounds of donuts = Number of pounds of dough used + Number of pounds of sugar used + Number of pounds of sprinkles used.

Plugging values.

Total number of pounds of donuts = 3/5 + 3/4 + 2/3.

We need to add all those fractions.

In order to add fracions, we need to find common denominator (lcd).

We have 5,4 and 3 in denominators.

Least common denominator(lcd) of 5, 4 and 3 is 60.

We need to make each denominator equals 60.

Multiplying first fracion by 12 in top and bottom, we get

3*12/5*12 = 36/60

Multiplying first fracion by 5 in top and bottom, we get

3*15/4*15 = 45/60

Multiplying first fracion by 20 in top and bottom, we get

2*20/3*20 = 40/60.

Therefore,

3/5 + 3/4 + 2/3 = 36/60 + 45/60 + 40/60

= 121/60

Let us convert 121/60 into mixed fraction.

Dividing 121 by 60 we get quotient =2 and remainder =1.

So, the mixed fraction is 2 1/60.

Therefore, Beulah made total 2 1/60 pounds of donuts.

Final answer:

The total weight of the donuts can be found by adding together the weights of the dough, sugar, and sprinkles, which comes to approximately 2.02 pounds.

Explanation:

The total weight of the donuts Beulah made can be found by adding the weights of the ingredients - dough, sugar, and sprinkles - together. First, she used 3/5 pounds of dough, to which she added 3/4 pound of sugar. Lastly, she used 2/3 pounds of sprinkles.

Now, let's add these quantities:

3/5 + 3/4 + 2/3 = 1.2 + 0.75 + 0.67 approximately.
Alternatively use a common denominator (60 for instance) to simplify the addition:
36/60 + 45/60 + 40/60 = 121/60 =2.02 pounds approximately.

Therefore, "Beulah made about 2.02 pounds of donuts".
