Answer:

5 batches

Step-by-step explanation:

fist to find how many cupcakes you need multiply the amount of people times amount of cupcakes per person

(if rule is 5 per person)

14x5=70

then you want to find how many batches to make

70/16=4.375

but you and make 0.375 batches so just make 1 more batch

so you should tell your dad to bake 5 batches

Answer:

I think the answer is 5.75 miles.

Step-by-step explanation:

If the drone flies 2,530 ft in 5 seconds, that means that in one minute it flies 30,360 ft. And 30,360 divided by 5,280 is 5.75.

There are 5.74 miles does the drone fly in a minute.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Ashley flies a drone 2,530 ft in 5 s.

Now,

Since, Ashley flies a drone 2,530 ft in 5 s.

We know that;

1 minute = 60 seconds

Hence, Number of miles in 1 minutes = 2530/5 × 60

                                                          = 30,360 ft

Since, We know that;

1 ft = 0.000189 miles

Hence, we get;

⇒ 30360 × 0.000189

⇒ 5.74 miles

Answer:

x=3

x=−3

Step-by-step explanation:

2x^2 - 5 = 13

Subtract 13 from both sides.

2x^2 - 5 - 13 = 0

Subtract 13 from −5 to get −18.

2x^2 - 18 = 0

Divide both sides by 2.

x^2 - 9 = 0

Consider x^2−9. Rewrite x^2−9 as x^2−3^2. The difference of squares can be factored using the rule: a^2−b^2=(a−b)(a+b).

(x−3)(x+3)=0

To find equation solutions, solve x−3=0 and x+3=0.

Answer:

Volume: 762 in³

LA: 448 in²

SA: 544 in²

Step-by-step explanation:

So first, the volume, the formula to find the area is base x height, so we have to find the base first:

8 x 12 ÷ 2 = 48

48 x 14  = 672

So the volume of the prism is 762 in³

Now, the lateral area, which is basically the surface area without the bases, or, in this case, the triangles:

10 x 14 = 140 x 2 = 280

12 x 14 = 168

168 + 280 = 448

So the LA = 448 in²

Now, for the surface area:

12 x 8 = 96 (usually, it would then be ÷ 2, but because there are two triangles, it isn't necessary)

96 + 448 (the LA) = 544

So the SA = 544 in²

hope this is right:)

Answer:

The coordinates of the midpoint between the two

points is (-1,4)

Step-by-step explanation:

Here, we want to find the midpoint between the two given points

To do this, we are to use the midpoint formula

We have this as;

m = (x1 + x2)/2, (y1 + y2)/2

(x1,y1) = (-7,9)

(x2,y2) = (5,-1)

(x,y) = (-7 + 5)/2, (9-1)/2

= (-2/2, 8/2) = (-1,4)

Answer:

3

Step-by-step explanation:

Given the function : y = x/3 + 1

If an input value, x is given as 6 ;

Output value, y can be obtained by Substituting the value x = 6 into the function and calculating the value of y

Calculation goes thus ;

y = 6/3 + 1

y = 2 + 1

y = 3

Output, y = 3

The figure of triangle LNM.

To find:

The Law of Sines for the given triangle.

Solution:

Law of sines: In triangle ABC,

[tex]\dfrac{\sin A^\circ}{a}=\dfrac{\sin B^\circ}{b}=\dfrac{\sin C^\circ}{c}[/tex]

Similarly, the Law of Sines for the given triangle LNM is:

[tex]\dfrac{\sin L^\circ}{l}=\dfrac{\sin N^\circ}{n}=\dfrac{\sin M^\circ}{m}[/tex]

Therefore, the correct option is b.

Note: Consider we need to find the circumference and area of the given circle.

Given:

A circle with radius 7.1 m.

To find:

The circumference and area of the given circle.

Solution:

Circumference of a circle is:

[tex]C=2\pi r[/tex]

Putting [tex]r=7.1,\pi=3.14[/tex], we get

[tex]C=2(3.14)(7.1)[/tex]

[tex]C=44.588[/tex]

[tex]C\approx 44.6[/tex]

Therefore, the circumference of the circle is 44.6 m.

The area of the circle is:

[tex]A=\pi r^2[/tex]

Putting [tex]r=7.1,\pi=3.14[/tex], we get

[tex]A=3.14(7.1)^2[/tex]

[tex]A=158.2874[/tex]

[tex]A\approx 158.3[/tex]

Therefore, the area of the circle is 158.3 sq. m.

Given:

I have walked 20% of the way to school.

I have 1200 metres more to walk than when I have 20% of the walk remaining.

To find:

The distance from home to school.

Solution:

Let x be the distance from home to school.

I have already walked 20% of the way to school and i have 1200 metres more to walk than when I have 20% of the walk remaining.

It means 1200 is [tex]100\%-20\%-20\%=60\%[/tex] of the total distance from home to school.

[tex]1200=\dfrac{60}{100}x[/tex]

[tex]1200=0.6x[/tex]

[tex]\dfrac{1200}{0.6}=x[/tex]

[tex]2000=x[/tex]

Therefore, the distance from home to school is 2000  metres.

How far, in metres, is it from my home to my school is 2,000 metres.

First step is to formulate

1200/(1-2×20%)

Second step is to find how far in metres

Distance=1200/(1-0.4)

Distance=1200/0.6

Distance=2,000

Inconclusion how far, in metres, is it from my home to my school is 2,000 metres.

Answer:

2.75feet

Step-by-step explanation:

Given data

Volume= 11.39 cubic feet

Length= 2.3 feet

Width= 1.8 feet

Depth= ???

The expression for the volume is  

Volume= Length*Width*depth

11.39=2.3*1.8*d

11.39=4.14d

d= 11.39/4.14

d= 2.75

Hence the depth is 2.75feet

Answer:

The population mean = sample mean = x`= 67.5

Population standard deviation = 13.369

Sample standard deviation= 4.225

Step-by-step explanation:

AS the population mean is not given we will calculate it from the sample.

The mean of the sampling distribution is equal to the population mean .

The sample mean is calculated by

x`= ∑x/n= 75,+ 62, +69,+65,+66,+64, +67,+70,+74 + 63/10

x`=675/10= 67.5

The standard deviation of the sample is equal to

u = σ/ √n   where σ is the population standard deviation and n is the number of observations.

Calculating the sample mean

s= √∑xi²/n- (∑x/n)²

s= √(45741/10)- (675/10)²

s= 4.2249

σ= u*√n= 4.229 *√10

σ=13.360

Step-by-step explanation:

The value of x is 10.

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

From the triangle it can be assume that ΔPSR is similar to ΔPQR.

Then, the ratio of corresponding sides of triangles are proportion.

So, PQ/ PS = QR/ RS
