How many batches should I tell Dad to make so we can each have 5 cupcakes?
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
Find the midpoint between the two points: (-7, 9) and (5, -1).
A. (18, -23)
B.(11, 4)
C.(13, 18)
D.(1.5, -2)
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)
Ashley flies a drone 2,530 ft in 5 s. At this rate how many miles does the drone fly in a minute? 1 mi = 5280 ft
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.
What is Multiplication?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

Solve the 2x^2 - 5 = 13
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.

An aquarium holds 11.39 cubic feet of water, and is 2.3 feet long and 1.8 feet wide. What is its depth? Round your answer to the nearest whole number.
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:
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

hassan and eva rode their bikes from the same starting point. Hassan rode his bike 5/6 of a mile, while eve rode hers 4/7 of a mile. which equation shows the mileage difference D in the distance they rode
Answer:
A
Step-by-step explanation:
5/6 > 4/7 so you'd have to subtract from 5/6 to even get to 4/7.
The equation for the mileage difference is 5/6 - d = 4/7.
What are expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:
(Mathematical Operator, Number/Variable, Expression)
Given the distance covered by Hassan = 5/6 of mile
distance covered by Eva = 4/7 of mile
5/6 = 0.833
4/7 = 0.57
since Hassan has covered more distance than Eva
so equation is 5/6 - d = 4/7
Hence option A is correct.

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.

The value of the modulus function is y = | x | - k , and as x increases , the value of y decreases and then increases
What is Modulus Function?Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Given data ,
Let the modulus function be represented as A
Now , the value of A is
y = | x | - k
where k is the factor of diminish
Now , when k = 4
The value of the modulus function is y = | x | - 4 and the graph is plotted
And , as x increases , the the value of y decreases and then increases
So , If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Hence , the modulus function is y = | x | - k

When 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.
How far, in metres, is it from my home to my school?
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

Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is inches. The heights of 10 randomly selected students are 75,62,69,65,66,64,67,70,74 and 63.
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
