Answers

Answer:

t₁ = 14

d = -2

Step-by-step explanation:

Given :-

t₆ = 4

t₁₀ = -4

To Find :-

t₁ and d

Solving :-

t₆ = t₁ + 5d = 4 -(1)

t₁₀ = t₁ + 9d = -4 -(2)

(2) - (1)

4d = -8

d = -2

t₁ + 5(-2) = 4

t₁ = 14

Solution :-

t₁ = 14

d = -2

Find the perimeter of the figure below, in feet
(Note: Diagram is NOT to scale)

Answers

Answer:

56.6 ft

Step-by-step explanation:

→ Perimeter = All sides added together

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

Answer:

56.6

Step-by-step explanation:

Perimeter is just adding all the outer value of an shape

So we add all the answers

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

but there is easier way

5.2 x 2 = 10.4

7.7 x 6 = 46.2

10.4 + 46.2 = 56.6

at the end don't forget to add "ft"

Answer = 56.6 ft

Carlos and his friends are going to out to bowl, eat dinner, and see a movie. The starts at 8:10 p.M. And they want to arrive 20 minutes before it starts. They will bowl for one hour and dinner will take 1 hour and 15 minutes. Travel time is 20 minutes to the bowling alley, 45 minutes ta the restaurant, and ten minutes to the theater. At what time should they plan to leave Carlo's house?

Answers

Answer:

They should leave Carlo's house by 4:20 PM

Step-by-step explanation:

The movie starts at 8:10 pm, they want to arrive 20 minutes before the movie starts

20 minutes before 8:10 pm = 7:50 pm.

Hence, they should arrive by 7:50 pm

Duration of their activities before the movie is calculated as:

They will bowl for one hour and dinner will take 1 hour and 15 minutes. Travel time is 20 minutes to the bowling alley, 45 minutes ta the restaurant, and ten minutes to the theater.

: 1 hour + 1 hour 15 minutes + 20 minutes + 45 minutes + 10 minutes

= 2 hour 15 minutes + 75 minutes

= 2 hour 15 minutes +1 hour 15 minutes

= 3 hours 30 minutes in total.

The time they are meant to leave is calculated as:

7:50 pm - 3 hours 30 minutes

= 4:20pm

If a sphere with diameter d is inscribed in a cube with side length e, what is the relationship between d and e?

Answers

Answer:

d = e

Step-by-step explanation:

An inscribed sphere in a cube will have a diameter equal to the edge length of the cube:

d = e

The distance between the faces of the cube is the same as the edge length.

In the above figure, m∠A = 30° and m∠B = (2x + 10)°. If angles A and B are complementary angles, what are the value of x and the measure of angle B?
A.
x = 55, m∠B = 60°
B.
x = 25, m∠B = 60°
C.
x = 70, m∠B = 150°
D.
x = 25, m∠B = 50°

Answers

Answer:

Step-by-step explanation:

option B

Complementary angles add up to 90°

m∠A + m∠B = 90

30 + 2x + 10 = 90

2x + 40 = 90

To find the value of x, we have to isolate x. To isolate x, first we have subtract 40 from both sides.

2x = 90 -40

2x = 50

Now, divide both sides by 2

x = 50/2

x = 25°

∠B = 2x + 10

= 2*25 + 10

= 50 + 10

∠B = 60°

mixo uses 250 ml of flour to make 10 pancakes. increase the quantity of flour so that she can make 25 pancakes.

Answers

so you would do 250g divided by 10 which would give you 25g. 25g is needed to make one pancake. you would then take 25g and times it by 25 to work out how many grams of flour you would need to make 25 pancakes. 25 x 25 = 625. your final answer is 625g of flour

The scatter diagram shows information about 10 cars.The 10 cars are the same type and make.

A)Show this information on the graph.

B) describe the relationship between the age and the value of the cars.

A car of the same type and make is 3 1/2 years old
C) estimate the value of the car

Answers

Answer:

a) you need to plot a cross on the graph (with the pencil) in the right place:

(x-axis: 4, y-axis: 2600)

b) the older the car is, the lower its value. there is a negative correlation between the cars age and its value.

c) you need to draw a line of best fit on the graph. where the line is at 3 1/2 years, that is its estimated value. (my guess is around £3000)

What is the solution to the linear equation: 2/5+p=4/5+3/5p

Answers

p = 1

Step-by-step explanation:

2/5 + p = 4/5 + 3/5p

2/5 + p = 3p/5

2/5 + p = (4 +3p)/5

2 + 5p = 4 + 3p

5p = 4 + 3p - 2

5p = 3p + 2

5p - 3p = 2

a store is charged $5.50 each for calculators and a delivery of $25 for the order. If stores sells the calculators for $8 each, how many calculators must be sold to produce a profit of at least $80?
