Step-by-step explanation:

By dividing each of the top numbers by 2, you get the results on the bottom. Therefore, 2 is the correct answer.

Answer:

v = 20 Sundaes

Step-by-step explanation:

Total number of sundaes = 25

Let the number of mint = m = 1/5 of total

= 1/5 of 25 = 1/5 × 25 = 5

∴ m = 5

Remainder = 25 - 5 = 20 Sundaes

let the number of chocolate = c = 1/2 of the remainder

1/2 of remainder = 1/2 of 20 = 20 ÷ 2 = 10 sundaes

∴ c = 10

let the number of vanilla = v

Therefore, finding v

25 = m + c + v

25 = 5 + 10 + v

25 = 15 + v

25 - 15 = v

v = 20 Sundaes

-[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Step-by-step explanation:

1/3 with both sides multiplied by two in order to have same denominator of both fractions, which is 6.

(1/3) x (2/2) = 2/6

Replacing 1/3 with 2/6,

the [ 1/3 - 5/6] becomes [2/6 - 5/6]

2/6 - 5/6 = -3/6

Simplify -3/6 by dividing both sides with 2,

-3/6 becomes -1/2

Answer:

86.64cm^2 (cm squared)

Step-by-step explanation:

So! This is a cube, a 6-sided shape. All the side lengths will be equal, which makes it really easy to calculate the surface area.

Since you calculate surface area by length x width, you do that once and then multiply it by six to find the total surface area.

So it'd be 3.8cm x 3.8cm = 14.44cm

and then 14.44 cm x 6 = 86.64cm^2, or cm squared.

Answer:

See explanations below

Step-by-step explanation:

Given the quadratic formula that expresses the temperature of a chemical reaction

C(t)=-12t² +8t +93

Given that C(t) = 110°, we are to find the value of t

Substitute

110 = -12t² +8t +93

-12t² +8t +93-110 = 0

-12t² +8t -17 = 0

12t² -8t + 17 = 0

Using the general formula;

t = -(-8)±√(-8)²-4(12)(17)/2(12)

t = 8±√64-816/24

t = 8±√-752/24

Since the value of t will give a complex number, hence the time doesn't exist when the reaction reaches 110°C

The temperature of the chemical does not reach 110°C

The equation is given as:

[tex]C(t)=-12t\² +8t +93[/tex]

When the reaction reaches 110 degrees, it means that:

C(t) = 110

So, we have:

[tex]110=-12t\² +8t +93[/tex]

Subtract 110 from both sides

[tex]0=-12t\² +8t +93 -110[/tex]

[tex]0=-12t\² +8t-17[/tex]

Rewrite the equation as:

[tex]12t\² -8t+17 = 0[/tex]

Using the quadratic formula, we have:

[tex]t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

So, we have:

[tex]t = \frac{-(-8) \pm \sqrt{(-8)\²-4(12)(17)}}{2(12)}[/tex]

[tex]t = \frac{-(-8) \pm \sqrt{-752}}{24}[/tex]

The square root of -752 is a complex number.

This means that, the equation does not have any solution when C(t) = 110

Hence, the temperature of the chemical does not reach 110°C

Can you like put the equation together it looks highly confusing

The solution for the given equation is 15.

The given equation is 2 = -7/4 + 1/4 x.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, 2 = (-7+x)/4

2×4 = -7+x

8 = -7+x

x = 8+7

x = 15

Therefore, the solution for the given equation is 15.

Answer:

Number of apples = 6

Number of oranges = 5

Step-by-step explanation:

At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55. He buys a total of 11 pieces of fruit.

Let

Number of apples = x

Number of oranges = y

x + y = 11 (1)

0.80x + 0.95y = 9.55 (2)

From (1)

x = 11 - y

Substitute into (2)

0.80x + 0.95y = 9.55 (2)

0.80(11 - y) + 0.95y = 9.55

8.8 - 0.80y + 0.95y = 9.55

- 0.80y + 0.95y = 9.55 - 8.8

0.15y = 0.75

y = 0.75/0.15

y = 5

Substitute y = 5 into (1)

x + y = 11 (1)

x + 5 = 11

x = 11 - 5

x = 6

Number of apples = 6

Number of oranges = 5

Answer:

a + 17 = 35

Step-by-step explanation:

The reason why that expression is correct is because there are two sides  of a rectange and one sides value is 17. In total the sides make 35 so how will you evaluate the answer

a + 17 = 35 ( something + 17 = 35)

When you add them they make 35 not when you substract them

Answer:

∠ GJK = 22°

Step-by-step explanation:

∠ HJI = ∠ JHG ( alternate angles ), then

7x - 16 = 5x + 8 ( subtract 5x from both sides )

2x - 16 = 8 ( add 16 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12 , so

∠ KJI = 7x - 16 = 7(12) - 16 = 84 - 16 = 68°

Then

∠ GJI = 90° ( vertex of a rectangle )

∠ GJK = 90° - 68° = 22°
