Since Jenny can do 1/2 of a mile in 1/4th of an hour, she can do twice as many miles, which is 1/2

Answer: It would cost $17.5 travel 25 miles.

Step-by-step explanation:

Given: Flat rate = $15

Charge per mile = $0.10

Total cost = Flat rate + (Charge per mile) (Number of miles)

Let x= Number of miles traveled.

So Total cost = 15 +0.10x

Put x= 25 miles

Total cost = 15 +0.10(25)

= 15+2.5 = $17.5

Hence, it would cost $17.5 travel 25 miles.

Answer:

2.25 miles

Step-by-step explanation:

When driving a car time taken is 20 minutes. This is equal to 20/60 hours , 1/3 hours / 0.3 hours

When riding a bike , time taken is 45 minutes. This is 45/60 hours , 3/5 hours/ 0.75 hours

The formula for speed is : Speed = Distance covered / time taken

The statement is that the driving speed is greater than biking speed by 4.5 mph

Assuming the distance to work is x miles then;

x/ 0.3 - x/0.75 = 4.5  ------eliminate 0.3 by multiplying each term by 0.3 to get

x- 0.3/0.75 x = 1.35 -------eliminate 0.75 by multiplying each term by 0.75 to get

0.75 x - 0.3 x = 1.0125

0.45 x = 1.0125

x= 1.0125 / 0.45

x = 2.25

Answer:

B

Step-by-step explanation:

Plug the coordinates in the answer choices to see if they give you 18.

Option A:  5(5) - 2(3) = 25- 6 = 9. Not it

Option B: 5(4) - 2(1) = 20 - 2 = 18. Works.

It has to be B because we've already tested (5,3) in option A and it wasn't correct.

Answer:

$247.37

Step-by-step explanation:

The total dinner bill with a tip for the large party is $177.90.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

The gratuity for a large party is 20% of the bill, so we can calculate the gratuity by multiplying the bill by 0.2.

Gratuity = bill x 0.2

Gratuity = 148.25 x 0.2

Apply the multiplication operation, and we get

Gratuity = 29.65

To find the total bill, we add the gratuity to the original bill.

Total bill = bill + gratuity

Total bill = 148.25 + 29.65

Apply the addition operation, and we get

Total bill = $177.90

Hence, the total dinner bill with a tip for the large party is $177.90.

Answer:

a. i. 150 cm³ ii. 150 cm³

b. i. 220 cm³ ii. 120 cm³

c. i. 297 cm² ii. 220 cm²

Step-by-step explanation:

a. For the cube

Dimensions of Cube = 5cm x 5cm x 5cm

Length of side = 5 cm

i. Total surface area A = 6L² where L = length of side = 5 cm

So, A = 6 × (5 cm)²

= 6 × 25 cm³

= 150 cm³

ii. Lateral surface area A' = 4L²

= 4 × (5cm)²

= 4 × 25 cm²

= 100 cm²

b. For the cuboid

Dimensions of Cuboid = Length, l = 10cm, Breadth, b = 5cm, Height, h = 4cm

i. Total surface area A = 2(lb + lh + hb)

= 2(10 cm × 5 cm + 10 cm × 4 cm + 4 cm × 5 cm)

= 2(50 cm² + 40 cm² + 20 cm²)

= 2(110 cm²)

= 220 cm²

ii. Lateral surface area A' = 2(lh + hb)

= 2h(l + b)

= 2 × 4 cm (10 cm + 5 cm)

= 8 cm × 15 cm

= 120 cm²

c. For the cylinder

Dimensions of Cylinder = Diameter, d = 7cm and height, h = 10cm

i. Total surface area, A = 2πr(r + h) where r = radius = d/2

A = πd(d/2 + h)

= 22/7 × 7 cm(7 cm/2 + 10 cm)  

= 22cm(3.5 cm + 10 cm)

= 22cm(13.5 cm)

=  297 cm²

ii. Lateral surface area A = 2πrh

= πdh

= 22/7 × 7 cm × 10 cm

= 22 cm × 10 cm

= 220 cm²

Answer:

71 degrees

Step-by-step explanation:

1. We know that the angle is unknown as demonstrated by '?'

2. The 17 side is opposite of the unknown angle

3. The 18 side the hypotenuse (not in contact with the right angle)

4. Therefore sine will be used where, sine(degree) = opposite/hypotenuse

5. The equation should be sine(degree) = 17/18

6. Since we don't know the degree we bring sine to the left and has a negative power of 1

7. The equation now becomes degree = sine^-1 (17/18)

8. The answer to this is 70.811... which equals 70 degrees and 48 minutes which rounds to the nearest degree of 71

Answer:

Value of discriminant is 20

Step-by-step explanation:

Formula of discriminant is:

[tex]D=b^2-4ac[/tex]

so our equation is

[tex]-4x^2+6x-1=0[/tex]

where a = -4, b = 6 , c = -1

so our discriminant becomes,

[tex]D=b^2-4ac\\D=(6)^2-4(-4)(-1)\\D=36-16\\D=20[/tex]

Since the discriminant is positive we have two distinct real number solutions or two distinct roots, and to solve the we just use the quadratic formula and get the two different values of x.

[tex]x_1=0.191\\x_2=1.309[/tex]

Im not sure but i think its 200 times

Step-by-step explanation:

Russia is 2 × 10³ times larger than Puerto Rico.

Exponentiation is a method of writing numbers, especially larger numbers, as the power of some number. A number can be written in the exponent form as aᵇ, where 'a' is called the base and 'b' is called the power or exponent.

Total land area of Russia = 20,000,000 km² = 2 × 10⁷ km²

Total land area of Puerto Rico = 10,000 km² = 10⁴ km²

Let X be the number of times that Russia is larger than Puerto Rico.

Then we can write,

Total land area of Russia = X × Total land area of Puerto Rico

2 × 10⁷ km² = X × 10⁴ km²

X = 2 × 10⁷ km² / 10⁴ km²

X = 2 × 10⁷ × 10⁻⁴

X = 2 × 10³

Hence, about 2 × 10³ times larger is Russia than Puerto Rico.

Answer:

This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof. If you know the height of the roof and the length for it to cover, you can use the Pythagorean Theorem to find the diagonal length of the roof's slope.

Answer:

Architecture, Engineering, Astronomy, etc.

Step-by-step explanation:

Engineers use the Pythagorean Theorem by knowing the height of the roof and the length for it to cover, and it will result in the diagonal length of the roof's slope.  Architects use the Pythagorean Theorem to calculate the heights of buildings and the lengths of walls. Astronomers sometimes use the theorem to calculate the paths of spacecraft, including rockets and satellites.

Step-by-step explanation:

i honestly didn't know what form you wanted so i put it in slope-intercept form for you :D

formula for slop-intercept form:

y=mx+b

12 = -1 ( -6 ) + b          -----> filled in the m, x and y

12 = 6 + b                   -----> do PEMDAS

12 - 6 = b                    -----> moved 6 to the other side to isolate variable

6 = b                           -----> you found the y-intercept

y = -x + 6                    ------> fill the equation in :D

Answer:

These triangles cannot be proven congruent.

Step-by-step explanation:

The image shows us two triangles with two pairs of congruent sides and one non-included angle. This theorem would be SSA, however, this is not enough to show congruency because the unknown side could be in two different places on the different triangles. Therefore, with this amount of information these triangles cannot be proven congruent.
