Answer:
If the two triangles are congruent (not just similar), then QS and TV would be equal. Thus, 3v + 2 = 7v - 6.
Solving this equation for v: 4v = 8, and v = 2.
Then QS = 3(2) + 2, or 8, and TV should be the same: 7(2) - 6 = 8.

Step-by-step explanation:
In a survey about favorite breakfast foods, 3/8 of those surveyed chose cereal , 0.125 chose yogurt, 0.1875 chose fruit, 5/8 chose toast which got the least number of votes.
The given question is a comparison of fractions and decimals to determine the smallest number. When all values are converted to decimals for easier comparison, we find that the smallest number is 0.125, which represents the people who chose yogurt as a breakfast food, hence, yogurt got the least number of votes.
Explanation:The given values in the problem represent different proportions of people's choices for breakfast. The question wants to find the breakfast food with the least number of votes. To do this, we need to understand the numerical values. All are fractions and decimal numbers that represent parts of 1 whole (or 100 percent). Here, the numbers are 3/8 for cereal, 0.125 for yogurt, 0.1875 for fruit, and 5/8 for toast. Converting all to either decimals or fractions for comparison, we get 0.375 for cereal, 0.125 for yogurt, 0.1875 for fruit, and 0.625 for toast.
Comparing these numbers, 0.125 (yogurt) is the smallest number. Therefore, among the given choices, the least number of people chose yogurt for their breakfast food.

What is fraction?"A number expressed as a quotient, in which a numerator is divided by a denominator. "
What is unitary method?"It is a method of finding the value of a single unit, and based on that value we can find the required value."
For given question,
A satellite makes 4 revolutions of the earth in one day.
⇒ 1 day = 4 revolutions
We need to find the number of revolutions in 6 1/2 days.
We can write the fraction [tex]6 \frac{1}{2}[/tex] as,
[tex]6 \frac{1}{2}[/tex] days
= [tex]\frac{13}{2}[/tex] days
= 6.5 days
By unitary method, for 6.5 days the number of revolutions would be,
= 6.5 × 4
= 26
Therefore, a satellite makes 26 revolutions of the earth in 6 1/2 days.

A photographer uses a light meter to measure the intensity of light from a flash bulb. The intensity for the flash bulb,I, in lux, is a function of the distance from the light, d, in meters, and can be represented by I(d)=10/d^2, d>0 determine the approximate instantaneos rate of change in the intensity of light at exactly 3m from flash bulb. determine the approximate instantaneos rate of change in the intensity of light at exactly 3m from flash bulb.
The approximate instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb is -20/27 lux per meter.
Explanation:The photographer uses a light meter to measure the intensity of light from a flash bulb. The intensity of the flash bulb, I, in lux, can be represented by the function I(d) = 10/d^2, where d is the distance from the light in meters.
To determine the approximate instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb, we need to find the derivative of the intensity function with respect to d. Taking the derivative, we get dI/dd = -20/d^3.
Substituting d = 3 into the derivative, we get dI/dd = -20/3^3 = -20/27.
Therefore, the approximate instantaneous rate of change in the intensity of light is -20/27 lux per meter at exactly 3m from the flash bulb.
The approximate instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb is approximately -0.741 lux/m.
Explanation:To determine the instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb, we need to find the derivative of the intensity function with respect to distance.
The intensity function is given as I(d) = 10/d^2, where d is the distance from the light in meters. To find the derivative, we can use the power rule for differentiation.
Taking the derivative of the intensity function gives us: dI/d(d) = -20/d^3.
At exactly 3 meters, the instantaneous rate of change in the intensity of light can be calculated by substituting d=3 into the derivative equation: dI/d(d) = -20/3^3 = -20/27. Therefore, the approximate instantaneous rate of change in the intensity of light at exactly 3m from the flash bulb is approximately -0.741 lux/m.

( C = 5b+200 ) this equation is used to find C, the total cost for painting a quantity of books (b) . What equation is equivanlent when solved for B in terms of C
To solve the equation C = 5b + 200 for b in terms of C, subtract 200 from both sides of the equation and then divide both sides by 5.
Explanation:To solve the equation C = 5b + 200 for b in terms of C, we need to isolate the variable b. First, subtract 200 from both sides of the equation:
C - 200 = 5b
Next, divide both sides of the equation by 5:
b = (C - 200)/5
So, the equivalent equation when solved for b in terms of C is b = (C - 200)/5.

Factor the polynomial: 8t^2 + 8t - 72
Final answer:
To factor the polynomial [tex]8t^2 + 8t - 72,[/tex] we first extract the common factor of 8, then factor the trinomial [tex]t^2 + t - 9[/tex] using the technique of finding two numbers that multiply to -72 and add up to 1, which are 9 and -8. Finally, we group and factor by grouping to get the factored form, 8(t - 8)(t + 9).
Explanation:
To factor the polynomial [tex]8t^2 + 8t - 72,[/tex], we will first look for the common factors and then apply factoring techniques. First, we can take out the common factor of 8:
8[tex](t^2 + t - 9)[/tex]
Next, we factor the trinomial inside the parentheses. We need two numbers that multiply to 8 * -9 = -72 and add up to 1. These numbers are 9 and -8. So, we can split the middle term based on these numbers:
[tex]t^2 - 8t + 9t - 9[/tex]
We group the terms to factor by grouping:
[tex](t^2 - 8t) + (9t - 9)[/tex]t(t - 8) + 9(t - 1)Now we factor out the common binomial factor:
(t - 8)(t + 9)
Therefore, the factored form of [tex]8t^2 + 8t - 72,[/tex] is 8(t - 8)(t + 9).

The hot summer fair is coming to town! Admission to the fair costs 12.99 and each ride costs 1.75. You have 35 to spend at the fair including admission.
The correct answer is:
12 rides
Explanation:
You have $35 to spend. Taking away the admission price, $12.99, we have
35-12.99 = $22.01 left.
Each ride costs $1.75. This means you can ride
22.01/1.75 = 12.577 or 12 rides. (This does not round up, as you would not have enough money to ride 13 rides.)

A telecommunication company has 7 satellites, two of which are sending a week signal. If two are picked at random without replacement, find the probability that both are sending a week signal
Hence, the probability that both are sending a weak signal is [tex]\frac{1}{21}.[/tex]
What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
The probability of an event is a number between [tex]0[/tex] and [tex]1[/tex], where, roughly speaking, [tex]0[/tex] indicates the impossibility of the event and [tex]1[/tex] indicates certainty.
Since, [tex]\frac{2}{7}[/tex] is the probability that the first satellite sends a weak signal.
And leaves six, and one is sending a weak signal.
So, the probability that the second also sends a weak signal it has the probability [tex]\frac{1}{6}[/tex].
By Combining these and we get
[tex]\frac{2}{7}[/tex]×[tex]\frac{1}{6}[/tex] = [tex]\frac{1}{21}[/tex] .
Hence, the probability that both are sending a weak signal is [tex]\frac{1}{21}.[/tex]
