Pls help me I’m stuck on this

Given:

Distance between Lily and Wilder = 810 miles

They drive towards each other with Lily driving at 55 mph and Wilder driving at 80 mph.

To find:

After how many hours will they meet?

Solution:

Lily driving at 55 mph and Wilder driving at 80 mph towards each other. So, the relative speed is:

Relative speed [tex]=(55+80)\text{ mph}[/tex]

                         [tex]=135 \text{ mph}[/tex]

We know that,

[tex]Time=\dfrac{Distance}{Speed}[/tex]

[tex]Time=\dfrac{810}{135}[/tex]

[tex]Time=6[/tex]

Therefore, Lily and Wilder will meet after 6 hours.

Your answer should be 12 feet, we do 4 * 15 which is 60, then divide by 5 which means 12 is your answer, or A.

Answer:

1120 in³

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

V = area of base × height , then

V = 80 × 14 = 1120 in³

Answer:

a 25 questions, 4 points   b 19 questions

Step-by-step explanation:

a 96:100 = 24 : x

x = (100 x 24)/96 = 25 questions

100 : 25 = 4 points

b 76:100 = x : 25

x = (76 x 25)/100 = 19 questions

Answer:

Question 1:

There are 25 questions on the test.

Each question is worth 4 marks each.

Question 2:

Your friend answered 19 questions correctly

Step-by-step explanation:

Question 1:

question answered = 24

percent earned = 96%

total number of points = 100%

[tex]\frac{questions answered }{percentage earned}[/tex] x 100

[tex]\frac{24}{96}[/tex] x 100 ⇒ 0.25 x 100 ⇒ 25

there are 25 questions on the test

[tex]\frac{100}{25} = 4[/tex]

each question is 4 marks each

Question 2:

percent earned by your friend = 76%

(percent earned by your friend x total number of question) ÷ 100

76 x 25 ÷ 100

1900 ÷ 100

= 19

Answer:

Here we don't have the options, so i will answer in a general way.

Every sentence that has the general structure like:

"something is greater than something"

"something is smaller than something"

"Something is no greater than something"

"something is no smaller than something"

There are a lot of other sentences, for example the ones like:

"N is at least equal to M" written as: N ≥ M

"N is at most equal to M" written as: N ≤ M

And there may be other ways to represent inequalities in sentences, but this is the most general way

Then the given sentence:

"One-half + k greater than 18"

This is written as:

1/2 + k > 18

Which is an inequality.

Answer:

1550 mL

Step-by-step explanation:

Total capacity of water = 4 Litre

4 L = 4 * 1000 mL = 4000 mL

200mL cups filled = 1 ; 200 mL

750mL cups filled = 3 ; 750 * 3 = 2250 mL

Total = (200 + 2250) mL = 2450 mL

Water left in filter :

Answer:

11699 square centimeters

Step-by-step explanation:

In ΔIJK, j = 800 cm, k = 240 cm and ∠I=173°. Find the area of ΔIJK, to the nearest square centimeter.

When given two sides of a triangle and an angle, the area of the triangle is calculated as:

1/2jksintheta

theta = 173°

Hence:

Area of triangle =

1/2 × 800 × 240 × sin 173

= 11699.456967 square centimeters

Approximately = 11699 square centimeters

Answer: I did the math in my head and I think it’s B

Step-by-step explanation:

Answer:

(the volume of the hemisphere has no units, so i will suppose that it is 6m^3)

For a sphere of radius R, the volume is:

V = (4/3)*pi*R^3

Where pi = 3.14

And a hemisphere is half of a sphere, then the volume of a hemisphere of radius R is:

V = (1/2)*(4/3)*pi*R^3

We know that the volume of the hemisphere is 6 m^3, then we have the equation:

6 m^3 = (1/2)*(4/3)*3.14*R^3

Now we can solve this for R.

6 m^3 = 2.1*R^3

∛(6 m^3/2.1) = R = 1.41 m

The radius of the hemisphere is 1.41m

Now we want to find the surface of a sphere with this radius (if the radius is the same, then the diameter is the same)

For a sphere of radius R, the surface is:

S = 4*pi*R^2

Then the surface of this sphere is:

S = 4*3.14*(1.41 m)^2 = 24.971 m^2

The correct relationship between the pair of angles m ∠AXC and m ∠BXC are,

A. They are supplementary angles,

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Measure of angle m ∠AXC and m ∠BXC are,

m ∠AXC = 100 deg.

m ∠BXC = 80 deg.

Hence, We get;

m ∠AXC + m ∠BXC

= 100 + 80

= 180 degree

Thus, The correct relationship between the pair of angles m ∠AXC and m ∠BXC are,

A. They are supplementary angles,

Answer:

We know that for every (3/4) cups of sugar, she uses (1/2) cups of flour.

Now let's find how much flour she needs to use for each case:

If she uses (1/8) cups of sugar, how much flour she uses?

First, we need to count how many times we have (3/4) cups of sugar in (1/8) cups of sugar, which is the quotient:

(1/8)/(3/4) = 4/(3*8) = 4/24 = 1/6

This means that we need to use (1/6) times (1/2) cups of flour.

this is:

(1/6)*(1/2) cups of flour = (1/12) cups of flour.

If she uses (4/3) cups of sugar, we need to count how many times we have (3/4) cups of flour in that amount, this is:

(4/3)/(3/4) = (4*4)/(3*3) = 16/9

Then we need to se (16/9) times (1/2) cups of flour, this is:

(16/9)*(1/2) cups of flour = (16/18) cups of flour = (8/9) cups of flour

If she uses (1/2) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:

(1/2)/(3/4) = 4/(2*3) = 4/6

Then she needs to use (4/6) times (1/2) cups of flour

this is:

(4/6)*(1/2) cups of flour = 4/(6*2) cups of flour = (1/3) cups of flour.

If she uses (1/4) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:

(1/4)/(3/4) = 4/(4*3) = 4/12

Then she needs to use (4/12) times (1/2) cups of flour

this is:

(4/12)*(1/2) cups of flour = 4/(12*2) cups of flour = (1/6) cups of flour.

If she uses (1/5) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:

(1/5)/(3/4) = 4/(5*3) = 4/15

Then she needs to use (4/15) times (1/2) cups of flour

this is:

(4/15)*(1/2) cups of flour = 4/(15*2) cups of flour = (2/15) cups of flour.
