What two integers have a sum of -19 and a product of 84?

Answer:

RULES:

Half of your diameter is ALWAYS your radius.

15 divided by 2 = 7.5 cm

6.5 divided by 2 = 3.25 in.

3 divided by 2 = 1.5 ft

8 divided by 2 = 4 m

Answer:

[tex]x = 0[/tex]

Step-by-step explanation:

Write the number in exponential form with the base of 2:

[tex] {2}^{x - 3} = {2}^{ - 3} [/tex]

Since the bases are the same, set the exponents equals.

[tex]x - 3 = - 3[/tex]

Cancel equal terms on both sides of the equation:

[tex]x = 0[/tex]

[tex]2 {}^{x - 3} = \frac{1}{8} [/tex]

To Find value of 'x'

[tex]2 {}^{x - 3} = \frac{1}{8} \\ \\ \implies2 {}^{x - 3} = 2 {}^{ - 3} \\ \\ \\ Since \: Bases \: Are \\ Equal \: We \: Need \\ To \: Evaluate \\ The \: Powers \\ \\ \implies \: x - 3 = - 3 \\ \\ \implies x = - 3 + 3 \\ \\ \implies \: x = 0[/tex]

The number of games, the friends have to play is an illustration of combination.

They have to play 28 games to ensure that they all play

Given

[tex]n = 8[/tex] --- number of friends

[tex]r = 2[/tex] --- only two friends can play at a time

For everyone else to play, we will make use of the following combination formula;

[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]

So, we have:

[tex]^8C_2 = \frac{8!}{(8 - 2)!2!}[/tex]

[tex]^8C_2 = \frac{8!}{6!2!}[/tex]

Expand

[tex]^8C_2 = \frac{8 \times 7 \times 6!}{6! \times 2 \times 1}[/tex]

[tex]^8C_2 = \frac{8 \times 7}{2 \times 1}[/tex]

[tex]^8C_2 = 4 \times 7[/tex]

[tex]^8C_2 = 28[/tex]

Hence, the 8 friends have to play 28 games to ensure that everyone else plays

Trust I'm taking the same test.

Ryan runs a total of 94.5 miles over the course of 18 days.

Speed is the ratio of the given distance and time.

It shows how fast an object is moving at a given time.

The formula is Distance / Time.

We can find the distance or time when the required values are given using this formula.

We have,

We can approach this problem by using arithmetic progression.

The first term is 1.5 miles, and the common difference is 0.3 miles.

So,

The nth term is given by:

an = a1 + (n-1)d

where a1 is the first term, d is the common difference, and n is the number of days.

We want to find the total distance Ryan runs over 18 days, which is the sum of the first 18 terms of the arithmetic progression:

S18 = (n/2) (a1 + an)

where n is the number of terms and a1 and an are the first and last terms, respectively.

Substituting the values we have:

a1 = 1.5 miles

d = 0.3 miles

n = 18

an = 1.5 + (18-1)0.3 = 6 miles

S18 = (18/2)(1.5 + 6) = 94.5 miles

Therefore,

Ryan runs a total of 94.5 miles over the course of 18 days.

Answer:

1.5 pounds of chocolate

Step-by-step explanation:

A single batch of ice cream takes [tex]\frac{3}{8}[/tex] of a pound of chocolate. For every added batch, we add another [tex]\frac{3}{8}[/tex] pound, or multiply [tex]\frac{3}{8}[/tex] by the number of batches.

In this case, we are making 4 batches, so we need to multiply [tex]\frac{3}{8}[/tex] by 4.

[tex]4\cdot \frac{3}{8}[/tex]

[tex]\frac{4}{1}\cdot \frac{3}{8} =\frac{3}{2}[/tex]

[tex]\frac{3}{2}=1.5[/tex]

We need 1.5 pounds of  chocolate to make 4 batches of ice cream.

The formula for the volume of a prism is V=Bh , where B is the base area and h is the height.

Step-by-step explanation:

*see attachement below for the diagram

Answer:

(252π + 20) cm²

Step-by-step explanation:

The surface area of the resulting solid = curved surface area of the cylinder + area of 1 base of the cylinder + 2(slant height of the cone)

✔️Curved surface area of cylinder = 2πrh

r = ½(12) = 6 cm

h = 18 cm

C.S.A = 2*π*6*18 = 216π cm²

✔️Area of 1 base = πr²

r = ½(12) = 6 cm

Area = π*6²

Area = 36π

✔️Slant height of the cone = 10 cm

✅The surface area of the resulting solid = 216π + 36π + 2(10)

= (252π + 20) cm²

Answer:

72 divided by 12 = 6 feet

Step-by-step explanation:

Since there are 12 inches in ONE FOOT you have to divide the total number of inches by the inches that are in a foot which is 12.

Answer:

110-degrees

Step-by-step explanation:

these are alternate exterior angles which are equal *congruent

Answer:

Since 110° and ? are alternate exterior angles, take the 110° and subtract 180°. Remember, 180° is a straight angle. So, 180°-110°= 70°.

The missing angle is 110°, I just solved for the remaining angle to help you figure it out more easily.

Answer:

The total distance traveled by the toy car is 14 m

Step-by-step explanation:

Given;

initial velocity of the car, u = 0

final velocity of the car, v = 4 m/s

time of motion, t₁ = 3 s

constant deceleration of the car, -a = 0.5 m/s²

time of motion, t₂ = 4 s

The total distance traveled by the car, is the area of triangle ABC (check the image uploaded).

[tex]Total \ distance = Area = \frac{1}{2} |BC| \times H\\\\Total \ distance = \frac{1}{2} \times 4\times 7\\\\Total \ distance = 14 \ m[/tex]

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

[tex]\frac{1}{2} \times 100 = 50[/tex]

Add both skateboarding and walking

[tex]30\% + 50\%\\\\= 30 + 50\\\\= 80[/tex]

Now, subtract that from a whole percent

[tex]100 - 80 = 20\\\\20\%[/tex]

Convert it to a decimal

[tex]20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2[/tex]

Answer:

x = 20

Step-by-step explanation:

(6x - 10) and (3x + 50) are vertical angles and are congruent, then

6x - 10 = 3x + 50 ( subtract 3x from both sides )

3x - 10 = 50 ( add 10 to both sides )

3x = 60 ( divide both sides by 3 )

x = 20
