Answers

X in the math problem is negative two

Answer:

x = -2

Step-by-step explanation:

4(x + 5) = 12

4x + 20 = 12

4x + 20 - 20 = 12 - 20

4x = -8

4x / 4 = -8 / 4

x = -2

Step-by-step explanation:

The retail price of a television set is $2500. If the buyer pays cash, the price is 10% below the retail price. If the set is bought on hire purchase, the buyer pays a downpayment of $500 and 18 monthly installments of $150.
A) Determine the difference between the hire purchase price and the cash price.
B) Calculate the difference as a percentage of the retail price.

Answers

Answer:

cash price:

10% = 250

2500 - 250 = $2,250

hire purchase:

2500 + 500 + 150(18) = $5,700

a) 5,700 - 2,250 = $3,450

NEED HELP ASAP 20 POINTS WHAT WOULD THE MEASUREMENT FOR THE EXTERIOR ANGLE (ANGLE B) BE???

Answers

Answer: I love these... Okay so the exterior angle is equal to the two remote interior angles meaning that 120 would be equal to 15x+5+22x+4 which is 70

Step-by-step explanation:

Solve the triangle. Round decimal answers to the nearest tenth.

Answers

Answer:

[tex]AB= 20.9[/tex]

[tex]A = 33.2^\circ[/tex]

[tex]C = 54.8^\circ[/tex]

Step-by-step explanation:

Given

The above triangle

Required

Complete the lengths

To do this, we make use of sine rule.

[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex]

[tex]\frac{14}{\sin A} = \frac{24}{\sin 70}[/tex]

[tex]\frac{14}{\sin A} = 25.54[/tex]

Cross multiply

[tex]\sin A * 25.54 = 14[/tex]

[tex]\sin A = \frac{14}{25.54}[/tex]

[tex]\sin A = 0.5482[/tex]

Take Arc sine of both sides

[tex]A = sin^{-1}(0.5482)[/tex]

[tex]A = 33.2^\circ[/tex]

To calculate C, we have:

[tex]C = 180 -A-B[/tex] --- angles in a triangle

[tex]C = 180 -55.2-70[/tex]

[tex]C = 54.8^\circ[/tex]

Calculate length AB using the sine rule.

[tex]\frac{AB}{sin C} = \frac{AC}{B}[/tex]

So, we have:

[tex]\frac{AB}{sin 54.8} = \frac{24}{sin 70}[/tex]

Make AB the subject

[tex]AB= sin 54.8*\frac{24}{sin 70}[/tex]

[tex]AB= sin 54.8* 25.54[/tex]

[tex]AB= 20.9[/tex] -- approximated

Answer:

  C. ... 3 1/4 cups

Step-by-step explanation:

The problem statement tells you that the other measures are combined. That means you're looking for an expression like ...

  3/8 × ((3 2/3) +(2 1/4) +(2 3/4))

This eliminates choices B and D.

If you look at the numbers in parentheses, you see that the 1/4 and 3/4 will have a sum of 1, so the only fraction in the sum will be 2/3. This eliminates choice A.

The only viable answer choice is C.

If you like, you can check to see that answer C is correct.

Researchers recorded that a certain bacteria population declined from 200,000 to 900 in 18 hours. At this rate of decay,
how many bacteria was there at 10 hours? Round to the nearest whole number,

Answers

Answer:

9,942 bacteria were there at 10 hours.

Step-by-step explanation:

Equation for population decay:

The equation for population decay, after t hours, is given by:

[tex]P(t) = P(0)(1-r)^t[/tex]

In which P(0) is the initial population and r is the decay rate, as a decimal.

Researchers recorded that a certain bacteria population declined from 200,000 to 900 in 18 hours.

This means that [tex]P(0) = 200000[/tex] and that when [tex]t = 18, P(t) = 900[/tex]. So we use this to find r.

[tex]P(t) = P(0)(1-r)^t[/tex]

[tex]900 = 200000(1-r)^{18}[/tex]

[tex](1-r)^{18} = \frac{900}{200000}[/tex]

[tex]\sqrt[18]{(1-r)^{18}} = \sqrt[18]{\frac{900}{200000}}[/tex]

[tex]1 - r = (\frac{900}{200000})^{\frac{1}{18}}[/tex]

[tex]1 - r = 0.7407[/tex]

So

[tex]P(t) = P(0)(1-r)^t[/tex]

[tex]P(t) = 200000(0.7407)^t[/tex]

At this rate of decay, how many bacteria was there at 10 hours?

This is P(10). So

[tex]P(10) = 200000(0.7407)^{10} = 9941.5[/tex]

Rounding to the nearest whole number:

9,942 bacteria were there at 10 hours.

Answers

Answer:

Question 1: Statistical

Question 2: Not Statistical

Step-by-step explanation:

Given

Question 1 and 2

Required

Are they statistical questions?

A question is said to be statistical if it can be answered through data collection and if there are variances in the collected data.

Using this yardstick, we can say that (1) is a statistical question because the frequency at which the band perform in a week can be determined by gathering data of their past practice.

This can not be said of (2) because (2) has not been done yet, there is no available data to make predictions and lastly, the variance of an unavailable data can not be determined.

Carols monthly take home pay is $1500. She spends $250 a month on food. What is the ratio of food costs to take home dollars?

Answers

Answer:

the ratio of food costs to take home dollars is 1:6

Step-by-step explanation:

The computation of the ratio of the foods cost to take home is shown below:

Given that

Monthly take home pay is $1,500

And, the spending month on food is $250

Based on the  above information

The ratio is

= $250 ÷ $1500

= 1:6

Hence, the ratio of food costs to take home dollars is 1:6

at first an athlete jogs at 4 miles per hr and then jogs at 6 miles per hour, traveling 8 miles in 1.5 hours. how long does the athlete jogs at each speed? the athlete jogged ? hours at a speed of 4 miles per hr and ? hour(s) at a speed of 6 miles per hour? ​

Answers

Answer:

The athlete jogged at 4 miles per hour for 30 minutes, and jogged at 6 miles per hour for 1 hour.

Step-by-step explanation:

Given that at first an athlete jogs at 4 miles per hour and then jogs at 6 miles per hour, traveling 8 miles in 1.5 hours, to determine how long does the athlete jogs at each speed the following calculation must be performed:

4 x 1.5 + 6 x 0 = 6

4 x 1 + 6 x 0.5 = 7

4 x 0.75 + 6 x 0.75 = 7.5

4 x 0.5 + 6 x 1 = 8

Therefore, the athlete jogged at 4 miles per hour for 30 minutes, and jogged at 6 miles per hour for 1 hour.

find the volume and surface area of each solid. you may use a calculator and use 3.14 as an approximation for pi

Answers

Answer:

Area = 452.16 cm²

Volume = 904.32 cm³

Step-by-step explanation:

The solid is a sphere, therefore,

Volume = ⁴/3πr³

Where,

π = 3.14

r = 6 cm

Volume = ⁴/3*3.14*6³

Volume = 904.319997 ≈ 904.32 cm³ (nearest hundredth)

Area = 4πr²

Area = 4*3.14*6²
