In order to know how much of the 3/8 is in the 1/4, you calculate the quotient between 1/4 and 3/8, just as follow:

1/4 ÷ 3/8

you can convert the previous quotient into a multiplication by inverting the second fraction:

1/4 ÷ 3/8 = (1/4) x (8/3) = 8/12 = 2/3

Hence, 2/3 is what 3/8 is in 1/4

over three successive Collins build 1/3, 1/5 and 1/4 of the brickwork of his new garage. What fraction must he complete on the f
garri49 [273]

Answer:

1 - 1/3 - 1/4 - 1/5

Step-by-step explanation:

Let's take it one step at a time.

Day 1 he completes 1/3 of the garage, so you subtract 1/3 from 1 which means he left 2/3

Day 2 he completed 1/4 more, so you again subtract, this time though 2/3 - 1/4, or in other words 1 - 1/3 - 1/4

So you do this one more time.  1 - 1/3 - 1/4 - 1/5

Can you handle this or do you need help with fraction subtraction.

Uma função f é dada por f(x) = ax + b, em que a e b são números reais. Se f(–1) = 3 e f(1) = –1, determine o valor de f(3).
ale4655 [162]
F(x) = ax + b
Usa-se a informacao dada para criar um sistema de 2 equacoes com 2 variaveis. Resolve-se o sistema pare determinar os valores de a e b.Uma vez que se sabe os valores de a e b, escreve-se a funcao f com os valores de a e b. Finalmente calcucla-se f(3) usando a funcao f.


f(-1) = 3

a(-1) + b = 3

f(1) = -1

a(1) + b = -1

O sistema de equacoes e o seguinte.
Resolvemo-lo par adicao. 
A variavel a e eliminada.



-a + b = 3
a + b = -1

2b = 2

b = 1

a + 1 = -1

a = -2

Agora sabemos the a = -2 e b = 1.
Escrevemos a funcao f usando os valores the a e b calculados..



f(x) = -2x + 1

f(3) = -2(3) + 1 = -6 + 1 = -5

f(3) = -5

Find the volume of a right circular cone that has a height of 15.6 cm and a base with a radius of 7.8 cm. Round your answer to t
sergey [27]

Answer:

356.8cm3

Step-by-step explanation:

Volume of a cone= 1/3 * base area * height.

Note: don't be confused by right circular cone ; a cone is gotten from a cylinder by dividing it into three parts. One from the right vertex slanted to the middle of the base; another from the left vertex slanted to the middle of the base and the remaining portion with the surface base at the top.

Going forward; base area =pi * raduis * raduis [ area of a circle; the base is a circle]

Volume= 1/3 * (3.142 * 7.8 * 7.8 *5.6) = 356.83cm3

Volume= 356.8cm3 [ to the nearest tenth].

Tenth means 1/10= 0.1; that is value after the decimal point.

Alfonso graphs the inequality x greater-than negative 8 using the steps below.
Musya8 [376]

Answer:

B-The graph is incorrect. He should have shaded to the right of –8.

Step-by-step explanation:

We examine the steps Alfonso follows in graphing the inequality x > -8.

Step 1: Draw a number line, and place an open circle at –8.

A number line going from negative 13 to negative 3. An open circle is at negative 8.

The first step is correct, since we use an open circle for > or < and a closed circle for \leq \:or\: \geq.

Step 2: Shade to the left of –8 to represent the infinite solutions to x greater-than negative 8.

This step is incorrect since <u>values to the left are always less than.</u>

He should have shaded to the right of -8.

<u>The error made is Option B. </u>

CHECK:

x=-7

-7>-8 (TRUE)
