ALMN AQRS. Solve for y. L 2x+11 /(y+10)° N (2y-40) Q S M R 3x-9
Answer:
50
Step-by-step explanation:
Since it's given that these are similar triangles then the measure of angles are equal
2y - 40 = y + 10 transfer like terms to the same side of equation
2y - y = 10 + 40 do the calculation (notice how the terms changes sign from + to - and from - to + when they are transferred)
y = 50

a knife is four times the cost of a spoon. 12 spoons and 16 knives cost £105.64. work out the cost of 1 knife
Answer:
£5.56Step-by-step explanation:
let K be the cost of a knife
S Ben the cost of a spoon
The statement “a knife is four times the cost of a spoon”
means K = 4S
means S = (1÷4)K
the statement “12 spoons and 16 knives cost £105.64”
means 12S + 16K = 105.64
⇔ 12(1÷4)K + 16K = 105.64
⇔ 3K + 16K = 105.64
⇔ 19K = 105.64
⇔ K = 105,64÷19

Ade think of a number.he double it and then subtract five.the results cannot less than 100 . find the range of value of x
Answer:
[tex]x > \frac{105}{2}[/tex]
Step-by-step explanation:
Let's say that the number is [tex]x[/tex].
He doubles the number and then subtracts five to get the number to be [tex]2x - 5[/tex]. If the result cannot be less than 100, then we can write the inequality [tex]2x - 5[/tex] > [tex]100[/tex]. Now, solving for x, we get [tex]x > \frac{105}{2}[/tex].

Martha bought a 0.35-kilogram bottle of spice. spice. She uses 80 grams a week. Is one bottle of spice enough for 6 weeks? Explain.
Answer:
She has not got enough spice for 6 weeks.
Step-by-step explanation:
Remark
0.35 kg = 0.35 * 1000 grams / kg = 350 grams.
Since she will use 6 * 80 = 480 grams for 6 weeks, and since 350 is less than 480, she does not have enough spice for six weeks.

Change from radians to degrees 7pi/4
The conversion of [tex]\dfrac{7\pi}{4}[/tex] in degrees will be equal to 315°
What is a radian?Radian is a unit of angle, equal to an angle at the centre of a circle whose arc is equal in length to the radius.
Here the given angle in radian is [tex]\dfrac{7\pi}{4}[/tex]
Angle in degrees is converted by multiplying it with [tex]\dfrac{180}{\pi}[/tex].
So the angle in degrees will be:-
[tex]=\dfrac{7\pi}{4}\times \dfrac{180}{\pi}[/tex]
[tex]=\dfrac{7\times 180}{4}[/tex]
Angle=315°
Therefore the conversion of [tex]\dfrac{7\pi}{4}[/tex] in degrees will be equal to 315°

The diameter of a circle is 7 cm, What is it's area/circumference????!
HELP!!!!
Answer:
Below in bold.
Step-by-step explanation:
Circumference = π * diameter
= π * 7
= 20.99 cm to nearest hundredth.
Radius of the circle = 1/2 * diameter = 7/2
= 3.5cm.
Area = π r^2
= π * 3.5^2
= 38.48 cm^2 to nearest hundredth.

◈ The diameter of a circle is 7 cm. What is its area? How about its circumference?
[tex]\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}\diamond[/tex]
We're asked to find the circle's circumference, which can be found using the formula below:-
[tex]\textsf{Formula for Circumference of a Circle:- \boxed{\bold{C=\pi d}}}[/tex]
Where:-
[tex]\bold{C=Circumference}[/tex][tex]\pi[/tex] = pi [3.14][tex]\bold{d=diameter}[/tex]As per provided information (d=7cm), we can easily find the circumference by substituting 7 for d:-
↬ [tex]\sf{C=\pi (7)}[/tex]
On simplification,
↬ [tex]\sf{C=7*3.14}[/tex]
Remember, 3.14 is pi.
On further simplification,
↬ C=21.98 cm.
So we conclude that the circumference of the given circle is:-
C=21.98 cm.
Now, how about the area?
[tex]\textsf{Formula for Area of a Circle:-\boxed{\bold{A=\pi r^2}}}[/tex]
Where:-
A=arear=radius (it's squared, which means it's multiplied times itself)Notice that we only have the diameter and not the radius.
We can easily find the radius by dividing the diameter by 2:-
3.5
So the radius is 3.5.
Substitute the value of r into the formula, which results in:-
↬ [tex]\sf{A=\pi (3.5)^2}[/tex]
On simplification,
A=12.25πOn further simplification,
A=12.25•3.14 (3.14 is pi)
On further simplification,
A=38.465 cm²
