Answer:
The mother is wrong
Step-by-step explanation:
What we do here will be to add the fractions of the cakes that we have
Mathematically, that will be;
14/12 + 5/6 = 24/12 = 2
This means that the mother is wrong and the cakes can actually be made into 2
The domain for the equation y = 3x + 14 is listed below. Find the range for the given domain.
D:{-5,0,4}
R:
Answer:
R:{-1,14,26}
Step-by-step explanation:
The domain of a function is all the x-values of the function. The range of a function is all the y-values of the function. Therefore, we must plug in every x-value in the function to get our outputs to create our range:
Given: y=3x+14
When x=-5:
y=3(-5)+14
y=-15+14
y=-1 (this is the first point of the range)
When x=0:
y=3(0)+14
y=0+14
y=14 (this is the second point of the range)
When x=4:
y=3(4)+14
y=12+14
y=26 (this is the last point of the range)
Therefore, our range is R:{-1,14,26}
The range for the given domain {-5, 0, 4} in the equation y = 3x + 14 is
{ -1, 14, 26 }.
We have,
To find the range for the given domain of {-5, 0, 4} in the equation
y = 3x + 14, we substitute each value of the domain into the equation and determine the corresponding range values.
When x = -5:
y = 3(-5) + 14
y = -15 + 14
y = -1
When x = 0:
y = 3(0) + 14
y = 0 + 14
y = 14
When x = 4:
y = 3(4) + 14
y = 12 + 14
y = 26
Therefore,
The range for the given domain {-5, 0, 4} in the equation y = 3x + 14 is
{ -1, 14, 26 }.

help me find the perimeter plzzz!
Answer:
2m-4
Step-by-step explanation:
double both of them and just simplify
the first one will become (6m-12) and the second will become (-4m+8)
subtract 6m and -4m so it's 2m
subtract -12 and 8 so it's -4
so the answer is 2m-4
Answer:
B. 2m - 4
Step-by-step explanation:
When simplifying the expression (3m - 6) + (3m - 6) + (-2m + 4 ) + (-2m + 4) while trying to find the perimeter, you will find your answer to be 2m - 4.

A scale on a map shows that 2.5 centimetres represents 15 kilometres what number of actual kilometres are represented by 17.5 centimetres on the map
Answer:
105km
Step-by-step explanation:
From the above question, the scale is
2.5 cm = 15km
Therefore,
17.5 cm = x
We Cross Multiply
2.5cm × x = 15km × 17.5 cm
x = 15km × 17.5cm/2.5
x = 262.5/2.5
x = 105 km
Therefore, the number of actual kilometres that are represented by 17.5 centimetres on the map is 105 kilometres.

The measure of angle Q is 75 degrees. Find the measure of angle P
Answer:
m<P = 30°
Step-by-step explanation:
∆PQR has two equal sides. An isosceles ∆ has two equal sides and the angles opposite the two equal sides are congruent to each other.
Thus, we can conclude that ∆PQR is an isosceles ∆ with two equal base angles, <P and <Q.
Since m<Q = 75°, therefore, m<R = 75°.
m<P = 180 - (75 + 75) (sum of ∆)
m<P = 30°

And I is throwing money at birthday party. She has $100 to spend. She buys a cake for $30, a giant balloon for $20, and 10 cups that each cost the same price. Create and solve any equation to determine the cost of each cup.
Answer:
$5 per cupStep-by-step explanation:
Step one:
given data
total amount = $100
cost of cake=$30
cost of balloon=$20
let the cost of 1 cup be x
so cost of ten cups = 10x
Step two:
The expression for the total amount is given as
100=30+20+10x
100=50+10
100-50=10x
50=10x
divide both sides by 10
x=50/10
x=$5
the cost of one cup is $5
the cost of ten cups is 5*10= $50

4 workers can make 32 widgets in an hour how many widgets can five workers make in 90 minutes
Answer:60
Step-by-step explanation:
32 divided by 4 is 8 8 an hour per worker 90 mins is hour and a half 8 times 5 40 each person can make 4 in 30 min so 20
40+20=60
sorry i am a bad explainer
60 widgets can five workers make in 90 minutes.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
4 workers can make 32 widgets in an hour .
1 hour = 60 mint.
now,
4 workers work 60 mint. to make 32 widgets
so, 1 workers work 60 mint. to make =32/4
=8 widgets
1 workers work 1 mint. to make =8/60 widgets
i.e. 1 workers work 90 mint. to make =8*90/60 widgets
5 workers work 90 mint. to make =8*90*5/60 widgets
solving we get,
5 workers work 90 mint. to make =60 widgets
hence, 60 widgets can five workers make in 90 minutes.

A blueprint of a plot of land has a scale of 1 1/4 cm to 3 1/4 m the length of the land is 20 cm on the blueprint if i represents the length of the actual peace of land. What is i
Answer:
52metre
Step-by-step explanation:
Let us use proportion in solving this question, the land has a scale of 1 1/4 cm to 3 1/4 m then the proportion is
( 1 1/4)/ (3 1/4 ) =[blueprint of the plot of land/length of the actual peace of land]
But we need to convert those mixed fractions to improper fraction for easy simplification
1 1/4= [(4×1)+4]= 5/2
3 1/4=[(4×3)+1)]=13/4
Then we can proceed with simplification as
(5/2)/(13/4)=[blueprint of the plot of land/length of the actual peace of land]
But we were given length of the actual peace of land as 20 cm, then
(5/2)/(13/4)=[blueprint of the plot of land/20]
If we cross multiply we have
[blueprint of the plot of land] ×13/4 =5/2 ×20
[blueprint of the plot of land] =(5/2 ×20)÷(13/4)
= 50/(13/4)
=(4×13)/50
= 52
Therefore, the length of the actual peace of land is 52metre
