Answer:

$280

Step-by-step explanation:

4(30)+160

120+160

280

Answer:

280 (see below)

Step-by-step explanation:

If C = total cost and t = number of t-shirts, then for 30 shirts, plug the amount of shirts into the variable for shirts in the equation given:

C = 4t + 160

C = 4 (30) + 160

C = 120 + 160

C = 280

Answer:

1. 33

2. -120

3. -623

Step-by-step explanation:

You do what is in the parenthesis and then multiply that by the number outside.

Question seems incomplete but will be explained with assumptions

Answer and explanation:

If for example, a car travels 30 km per hour, then it would travel 60km in 2 hours and 90km in 3 hours and so on

We can apply the formula for distance as such:

Distance(d)= Speed(s) × time(t)

d=st

Where d is distance travelled say 60km

S is speed= 30km/hr

Time = 2 hrs

Also to calculate speed when distance and time is given, we can make speed the subject of the formula:

s=d/t

To calculate time when distance and speed are given, we can make time the subject of the formula:

t=d/s

Answer:

0.0043957 ; 0.105498 ; 2nd option is better

Step-by-step explanation:

Option 1:

First card :P(club) = 13/52

Second card: P(diamond) = 13/51

Third card : P(heart) = 13 / 50

Fourth card: P(spade) = 13/49

Hence,

P(club, diamond, heart, spade) = (13/52) * (13/51) * (13/50) * (13/49) = 0.0043957

Probability of winning $10 = 0.0043957

2nd option:

P(card of different suit) [order of arrangement does not matter]

(13C1 * 13C1 * 13C1 * 13C1) / 52C4

= 28561 / 270725

= 0.105498

Probability of winning $10 = 0.105498

Because the probability of winning for the second option is higher than for the first option, then the second option is better.

Answer:

1 4/5

Step-by-step explanation:

198 woman to 110 is basically a ratio, so we should put it like this: 198:110

Now, a ratio that needs to be simplified is basically a fraction, so: 198/110

Now we divide the fraction.

First, find the GCF of both numbers.

The GCF of 198 and 110 are both 22.

Now we divide, and we get 9/5, and we turn it into a mixed number, 1 4/5.

Answer:

In triangle KLM, the measure of angle K is 119 degrees, KL=23, and KM=20.

The measurement of the angle KLM is 64°.

An angle is a geometrical shape that is formed by two rays or lines, called the sides or arms of the angle, that share a common endpoint, called the vertex of the angle.

Given is a figure, we need to find the measurement of ∠KLM,

Here,

∠KLM + ∠KLJ = 180° [linear pair]

20x+4 + ∠KLJ = 180°

∠KLJ = 176-20x

Consider the triangle, KLJ,

∠KLJ + ∠KJL + ∠JKL = 180° [sum of the interior angles of a Δ)

8x+18+6x+4+176-20x = 180°

-6x = -18

x = 3

So, ∠KLM = 20(3)+4 = 64°

Hence, the measurement of the angle KLM is 64°.

Step-by-step explanation:

If Todd has to pay $14,000 in tuition for his school each year and uses $6,500 in financial aid each year all for 2 years, the money he needs to save can be modeled by:

2(-$14000 + $6500) + 2(12x) = 0.

x is the minimum amount of money he needs to save in order to cover this expense without debt.

Thus 2(-$14000 + $6500) + 2(12x) = 0 →

2(-$7500) + 24x = 0 → -$15000 + 24x = 0 →

24x = $15000 → x = $625

6x + 2y = 10 and -4x=-8  system of equations has the same solution as the system of equations 6x + 2y = 10 and 8x + 4y = 12

Two or more expressions with an Equal sign is called as Equation.

The given system of equations are

6x+2y=10..(1)

2y=10-6x...(2)

We need to find system of equation which having same solutions as above.

From equation (2)

y=5-3x

Now substitute y value in equation 1.

8x+4(5-3x)=12

8x+20-12x=12

-4x=12-20

-4x=-8

Hence, 6x + 2y = 10 and -4x=-8  system of equations has the same solution as the system of equations 6x + 2y = 10 and 8x + 4y = 12

The simplified form of expression 3 times the square root of 200 is 30√2 ( thirty times square root 2 ) .

To simplify the expression 3 times the square root of 200, we can break it down into smaller components .

First, let's simplify the square root of 200 :

√ 200 = √ ( 100 × 2 ) = √ 100 × √ 2 = 10√2

Now, we substitute this simplified value back into the original expression :

3 × √ 200 = 3 × ( 10√ 2 ) = 30√ 2

Therefore, the simplified form of 3 times the square root of 200 is 30√2 .
