Answer:

the answer is 22.23

Step-by-step explanation:

you multiply 2.85 times 7.8 and you get 22.23

Juan needs to spend  22.23 to buy 7.8 pounds of seedless red grapes.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Juan bought 7.8 pounds of seedless red grapes for 2.85 per pound.

Here the cost of the unit pound is already given, Now to obtain the cost 7.8 pounds we have to multiply the cost of the unit pound and no. of pounds which is,

= (7.8×2.85).

= 22.23.

A. The total cost of the small popcorns

Step-by-step explanation:

Let us suppose Trinity is going to the movies with [tex]x[/tex] number of friends, we know she will pay for only her own movie ticket hence cost of movie ticket will be a constant (say [tex]a[/tex]) for her expense and cost of popcorn will be price of one popcorn (say [tex]b[/tex]) multiplied by number of friends.

considering the situation, her expense will be given by the function-

[tex]f(x) = a + bx[/tex]

Answer:

x = 10

Step-by-step explanation:

Begin by factorising the numerator/ denominator of the left side

x² - 14x + 49 = (x - 7)² ← perfect square

x² - 49 = (x - 7)(x + 7) ← difference of squares

Thus left side becomes

[tex]\frac{(x-7)^2}{(x-7)(x+7)}[/tex] → x ≠ ± 7

Cancel (x - 7) on numerator/denominator, leaving

[tex]\frac{x-7}{x+7}[/tex]

Returning to the equation, that is

[tex]\frac{x-7}{x+7}[/tex] = [tex]\frac{3}{17}[/tex] ( cross- multiply )

17(x - 7) = 3(x + 7) ← distribute both sides

17x - 119 = 3x + 21 ( subtract 3x from both sides )

14x - 119 = 21 ( add 119 to both sides )

14x = 140 ( divide both sides by 14 )

x = 10

Answer:

Step-by-step explanation:

The mean is measured as

mean = [tex]\frac{score}{count}[/tex]

After 5 tests the mean is 84, that is

[tex]\frac{score}{5}[/tex] = 84 ( multiply both sides by 5 )

score = 420

let the sixth test score be x, then

[tex]\frac{420+x}{6}[/tex] = 85 ( multiply both sides by 6 )

420 + x = 510 ( subtract 420 from both sides )

x = 90

Require to score 90 on the sixth test

Answer:

(-1,-5)

Step-by-step explanation:

Starting at (0,0), we perform the first translation:

T<5,-7> implies that we move the point 5 units to the right (in the x (horizontal) direction), and 7 units DOWN in the y <vertical) direction.

From there we do the second translation: T<-6,2>

which means: 6 units to the left (in the horizontal direction) which takes us to  "-1" for the x value, and 2 units up (vertical) which takes us to -5 for the y value.

Therefore the new location is (-1,-5)

Answer:

radius^2 = 3 * Volume / (PI * height)

radius^2 = 3 * (142 cc / 3.14159265 * 8.5)

radius^2 = 3 * (142 cc / 26.703537525 )

radius^2 = 15.9529425493

radius = 4.0 cm

Step-by-step explanation:

Final answer:

The radius of a cone-shaped paper cup with a volume of 142 cubic centimeters and height of 8.5 centimeters is approximately 4 centimeters when rounded to the nearest centimeter.

Explanation:

To determine the radius of a paper cup that is a right circular cone with a given volume, we will use the formula for the volume of a cone V = (1/3) πr²h. The volume, V, is provided as 142 cubic centimeters, and the height, h, is 8.5 centimeters.

Rearrange the formula to solve for the radius, r, as follows:

Divide both sides by π and 8.5 to isolate ¹⁄₃r² on one side.

Multiply both sides by 3 to get rid of ¹⁄₃.

Take the square root of both sides to solve for r.

Once we have the value of r, we round it to the nearest centimeter as the question asks for an approximation to the nearest whole number.

Let's perform the calculation:

V = (1/3)πr²(8.5) => 142 = πr²(8.5/3)

142 = (π × 8.5/3)r²

142 / (π × 8.5/3) = r²

r² ≈ 142 / (3.14159 × 8.5/3)

r² ≈ 15.91549431

r ≈ √15.91549431 ≈ 3.99 cm

Round r to the nearest centimeter: r ≈ 4 centimeters

Answer:

Step-by-step explanation:

what you would do is just set both functions equal to each other and then solve for x. so set x+109=x+89. then get you numbers on one side and your x's on one side. so subtract x from on side getting x-x+89=109 now you subtract 89 from both sides getting x-x=109-89 getting 0= 20 0 dosen not = 20 so you would have zero there is no value that you could plug in for x to get them both equal

Answer:

C

Step-by-step explanation:

From the given options, only option E.7.777 is a repeating decimal because its decimal part '7' repeats indefinitely.

In mathematics, a repeating decimal is a decimal fraction that after some place repeats the same sequence of digits indefinitely. From the options given: A.-0347, B.3.611, C.-1.35, D.2.153, and E.7.777, we are looking for which numbers have decimal parts that repeat.

Option A.-0347 is not a repeating decimal because the decimal part '0347' does not repeat indefinitely. Option B.3.611 and Option D.2.153 also do not have repeating decimal parts.

Option C.-1.35 does not have a repeating decimal part either. However, Option E.7.777 is indeed a repeating decimal, as the decimal part '7' repeats indefinitely.

Angle HAB and Angle FAE are congruent angles

Step-by-step explanation:

we know that

Two angles are supplementary if their sum is equal to 180 degrees

In this problem

m∠FAH+m∠HAB=180°  ----> by a linear pair

Remember that

A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. A linear pair of angles must add up to 180 degrees

m∠FAH+m∠FAE=180°  ----> by a linear pair

therefore

m∠HAB=m∠FAE -----> by vertical angles

Angle HAB and Angle FAE are congruent angles

Answer:

<HAB is congruent with <FAE

Answer:

Step-by-step explanation:

F = m / a

cross multiply

m = F /a

To solve F=ma for mass, divide both sides by acceleration to get m=F/a. For a wagon of 55 kg accelerating at 0.0255 m/s², the calculated force is 1.4025 newtons.

To solve the formula F=ma for mass (m), you need to isolate the variable m. This is done by dividing both sides of the equation by acceleration (a), thus the rearranged formula becomes m = F/a. When we apply this to a practical example, if a wagon with mass 55 kg accelerates at a rate of 0.0255 m/s², the force on the wagon can be calculated using the same formula. By substituting the values into the formula, the force F is found as F = 55 kg × 0.0255 m/s², which equals 1.4025 newtons (N).
