if the original recipe calls for 50 portions, 6oz each and the new recipe calls for 100 portions at 5oz each, what is the recipe

kvv77 [185]

By using multiplication and division of integers, it can be calculated that

Conversion factor of the recipe = $\frac{500}{300}$ = 1.6

What is multiplication and division of integers?

At first it is important to know about integers

Integers are those numbers which has no fractional part. Integer can be positive, negative and zero is also an integer.

Repeated addition is called multiplication. Multiplication is used to find the product of two or more integers.

What is division?

Division is the process by which value of single unit can be calculated from the value of multiple unit.

The number to be divided is known as dividend, the number by which the dividend is divided is the divisor, the result obtained is the quotient and the remaining part is the remainder.

There is a well known formula for division

Divisor x Quotient + Remainder = Dividend.

This is a word problem where multiplication and division of integers is required

The original recipe calls for 50 portions, 6oz each

Required yield of the original recipe = 50 $\times$ 6 = 300 oz

The new recipe calls for 100 portions at 5oz each

Required yield of the new recipe = 100 $\times$ 5 = 500 oz

Conversion factor of the recipe = $\frac{500}{300}$ = 1.6

A spotlight on the ground shines on a wall 12 m away. If a man 2 m tall walks from the spotlight toward the building at a speed

N76 [4]

Answer:

the length of his shadow on the building is decreasing at the rate of 0.525 m/s

Step-by-step explanation:

From the diagram attached below;

the man is standing at point D with his head at point E

During that time, his shadow on the wall is y = BC

ΔABC and Δ ADE are similar in nature; thus their corresponding sides have equal ratios; i.e

$\dfrac{AD}{AB} = \dfrac{DE}{BC}$

$\dfrac{8}{12} = \dfrac{2}{y}$

8y = 24

y = 24/8

y = 3 meters

Let take an integral look at the distance of the man from the building as x, therefore the distance from the spotlight to the man is 12 - x

∴

$\dfrac{12-x}{12}=\dfrac{2}{y}$

$1- \dfrac{1}{12}x = 2* \dfrac{1}{y}$

To find the derivatives of both sides ;we have:

$- \dfrac{1}{12}dx = 2* \dfrac{1}{y^2}dy$

$- \dfrac{1}{12} \dfrac{dx}{dt} = 2* \dfrac{1}{y^2} \dfrac{dy}{dt}$

During that time ;

$\dfrac{dx}{dt }= 1.4 \ m/s$ and y = 3

So; replacing the value into above ; we have:

$-\dfrac{1}{12}(1.4) = - \dfrac{2}{9} \dfrac{dy}{dt}$

$\dfrac{dy}{dt} = \dfrac{\dfrac{ 1.4} {12 } }{ \dfrac{2}{9}}$

$\dfrac{dy}{dt} = {\dfrac{ 1.4} {12 } }*{ \dfrac{9}{2}}$

$\dfrac{dy}{dt} =0.525 \ m/s$

Thus; the length of his shadow on the building is decreasing at the rate of 0.525 m/s

Find the measure for LQR.

Charra [1.4K]

Answer:

Option A

$m\angle LQR=126^o$

Step-by-step explanation:

step 1

Find the value of b

we know that

$m\angle MQR=m\angle LQX$ ----> by vertical angles

substitute the given values

$(-3b+63)^o=(90-12b)^o$

solve for b

$12b-3b=90-63\\9b=27\\b=3$

step 2

Find the measure of angle LQR

we know that

$m\angle LQR+m\angle MQR=180^o$ ---> by supplementary angles (form a linear pair)

$m\angle MQR=(-3b+63)^o$

substitute the value of b

$m\angle MQR=(-3(3)+63)=54^o$

substitute in the expression above

$m\angle LQR+54^o=180^o$

$m\angle LQR=180^o-54^o=126^o$
