Answer:
The roast weighed 1.375 kg
Step-by-step explanation:
Here, we want to know what the roast lamb will weigh in kilograms given its cooking time.
From the question, we are told that to cook 250 grams, 20 minutes is need.
So let’s make a relationship here,
Firstly let’s express 1 hour and 50 minuets in minutes, that will be 60 + 50 = 110 minutes( 1 hour is 60 minutes)
Now;
let’s have our relationship;
20 minutes = 250 grams
110 minutes = x grams
By cross multiplication;
20 * x = 250 * 110
20x = 27,500
x = 27500/20
x = 1,375 grams
But, mathematically 1000g = 1kg
So 1,375 will be 1375/1000 = 1.375 kg

Rupert buys a bicycle with a marked price of £ 12500.He gets a rebate of 10% on it. After getting
the rebate ,tax is charged at the rebate of 8%. Find the amount he will have to pay for the bicycle.
Answer:
£ 12,150
Step-by-step explanation:
Marked price of bicycle = £ 12500
Rebate = 10%
Amount of rebate = 12500*10/100 = £1250
Rebated price = 12500 - 1250 = £ 11,250
Tax = 8%
Amount of tax = 11250*8/100 = £ 900
Total amount paid for bicycle = Rebated price + amount of tax
= £ 11,250 + £ 900
= £ 12,150

An entry level designer's annual pay is $49,868 based on 52 weeks per year. Due to the economy, his company is having to cut back on the number of weeks that it employs its designers. If the firm cuts the work year to 50 weeks but keeps the same rate of pay, how much should the designer expect his annual pay to decrease? Round your answer to the nearest dollar.
Answer: his pay will decrease by $1,918
Step-by-step explanation:
49868/52 = 959
959 × 50 = 47950
49868 - 47950 = 1918

One week, Wyatt earned $70.40 at his job when he worked for 4 hours. If he is paid the same hourly wage, how many hours would he have to work the next week to earn $281.60?
Answer: 8 hours
Step-by-step explanation: he gets 70.40$ to work for 4 hours so you'll have to multiply 4 by 70.40 to represent it's doubling to 8 and you'll get 281.60
70.40x4=281.60
so add this 4 to the other 4 it makes 8 because that's how much it would take to get there 4 steps up to really =8

what steps could be used to solve the equation 1 + 3x = -x + 4.
Answer:
Combing like terms
Step-by-step explanation:
Answer: x = 3/4
Step-by-step explanation:
1+3x = -x+4
or, 1-4 = -x-3x
or, -3 = -4x
or, 4x = 3
or, x = 3/4
so, x = 3/4

find the pattern for the following sequence, then use the pattern to show the next two terms. 1, 1, 2, 3, 5, 8, 13...
Answer I believe the next two terms are 21 and 34!
Step-by-step explanation:
the sequence is 1,1,2,3,5,8,13...
So for the first number, 1 + 0 is 1, for the next sequence 1 + 1 is 2, 1 + 2 is 3.
Add the number with the number behind it to get your next number!

The formula for the volume of a pyramid is V=⅓Bh, where B is the area of the base of the pyramid and h is the height of the pyramid.
What is the volume of this pyramid in cubic inches?
Answer:
80
Step-by-step explanation:
v=lwh/3= 5*6*8/3 = 80
The volume of this pyramid in cubic inches is 80 inch³.
What is Volume?Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies.
The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
We have,
V = (1/3) (b) (h)
So, the Volume of Pyramid is
= 1/3 x base aera x height
= 1/3 x 5 x 6 x 8
= 5 x 2 x 8
= 80 inch³

Step-by-step explanation:
[tex]\frac{\sqrt{1-\cos ^2\left(x\right)}}{\sin \left(x\right)}+\frac{\sqrt{1-\sin ^2\left(x\right)}}{\cos \left(x\right)}[/tex]
LCM is [tex]\cos \left(x\right)\sin \left(x\right)[/tex]
Adjust fractions:
[tex]\frac{\sqrt{1-\cos ^2\left(x\right)}\cos \left(x\right)}{\sin \left(x\right)\cos \left(x\right)}+\frac{\sqrt{1-\sin ^2\left(x\right)}\sin \left(x\right)}{\cos \left(x\right)\sin \left(x\right)}[/tex]
Combine:
[tex]\frac{\sqrt{1-\cos ^2\left(x\right)}\cos \left(x\right)+\sqrt{1-\sin ^2\left(x\right)}\sin \left(x\right)}{\sin \left(x\right)\cos \left(x\right)}[/tex]
--------------------------------------------------------
We will take a look at [tex]\sqrt{1-\cos ^2\left(x\right)}\cos \left(x\right)[/tex].
Using the identity that [tex]\cos ^2\left(x\right)+\sin ^2\left(x\right)=1[/tex], we know that [tex]1-\cos ^2\left(x\right)=\sin ^2\left(x\right)[/tex].
Therefore, [tex]\sqrt{1-\cos ^2\left(x\right)}\cos \left(x\right)=\sqrt{\sin ^2\left(x\right)}\cos \left(x\right)=\sin \left(x\right)\cos \left(x\right)[/tex]
-----------------------------------------------------------------------------------------------
Similarly, [tex]1-\sin ^2\left(x\right)=\cos ^2\left(x\right)[/tex] so
[tex]\sqrt{1-\sin ^2\left(x\right)}\sin \left(x\right)=\sqrt{\cos ^2\left(x\right)}\sin \left(x\right)=\cos \left(x\right)\sin \left(x\right)[/tex]
-------------------------------------------------------------------------------
We will finally end up with
[tex]\frac{\sin \left(x\right)\cos \left(x\right)+\cos \left(x\right)\sin \left(x\right)}{\sin \left(x\right)\cos \left(x\right)}[/tex]
Add:
[tex]\frac{2\sin \left(x\right)\cos \left(x\right)}{\sin \left(x\right)\cos \left(x\right)}[/tex]
Cancel out sin(x):
[tex]\frac{2\cos \left(x\right)}{\cos \left(x\right)}[/tex]
Cancel out cos(x):
