(w2x−3)÷10⋅z when w=−6, x = 1.2, and z=−6/7

Enter your answer as a simplified mixed number in the box.

Answers

Step-by-step explanation:

W=-6, x=1.2, and z=-6/7

(W²x-3)÷10-z

we substitute

((-6²)(1.2)-3)÷10-(-6/7)

((-36)(1.2)-3) ÷10-(-6/7)

(-43.2-3) ÷10(6/7)

(-46.2)÷60/7

-46.2÷60/7

-46.2*7/60

-46.2/1*7/60

-323.4/60

-5.39

Required value of (w²x−3)÷10⋅z when w=−6, x = 1.2, and z=−6/7 is (-4.69)

What is the value of of (w²x−3)÷10⋅z when w=−6, x = 1.2, and z=−6/7 ?

We know,

By BODMAS rule,

B - Bracket

O - Of

D - Division

M - Multiplication

A - Addition

S - Subtraction

We should maintain the following sequence,

Bracket - Of - Division - Multiplication - Addition - Subtraction

We are applying BODMAS rule.

Here,[tex]( {w}^{2} x - 3) \div 10 . z[/tex] and w=−6, x = 1.2, and z=−6/7

We are putting value of w,x,z in given expression and get

[tex]( {( - 6)}^{2} \times 1.2 - 3) \div 10 ( - \frac{6}{7} ) \\ = -(36 \times 1.2 - 3) \div \frac{60}{7} \\ = -(43.2 - 3) \div \frac{60}{7} \\ = -40.2 \div \frac{60}{7} \\= -40.2 \times \frac{7}{60} = -4.69[/tex]

Therefore, Required value of the given term is (-4.69)

The ratio of boys to girls in the sixth grade is 3:5. If there are 20 more girls than boys, how many total students are in the sixth grade?

Answers

Answer:

80

Step-by-step explanation:

.375, .525, .25 difference. 20/.25 =80

There are 80 students in the sixth grade.

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

Thus, a = px, b = qx

We have been given that ratio of boys to girls in the sixth grade is 3:5. If there are 20 more girls than boys, then

Now we need to do as;

b = 20 + g

3x = 20 + 5x

x  = 10

Now The students  are 8p

8 x 10 = 80

The temperature in Doha, Qatar on 1 June is 40°C. Over
the next two days this temperature increases by 10%
followed by a decrease of 10%. Find the temperature in
Doha on 3 June.

Answers

Answer:

39.6°C

Step-by-step explanation:

10% of 40°C is 40 × 10/100

=4

temp on 2 June = 40+4 = 44°C

now 10% of 44°C is 44 × 10/100

=4.4

temp on 3 June = 44 - 4.4 = 39.6°C

The measures of the angles of a triangle are shown in the figure below. Solve for x.
(6x+3)°
27°

Answers

Answer:

x = 10

Step-by-step explanation:

1. The sum of all angle measures in any triangle is equal to 180 degrees.

This means that 90 + 6x + 3 + 27 = 180

2. (Solving)

Step 1: Combine like terms.

[tex](6x)+(90+3+27)=180[/tex] [tex]6x + 120 = 180[/tex]

Step 2: Subtract 120 from both sides.

[tex]6x + 120 - 120 = 180 - 120[/tex] [tex]6x = 60[/tex]

Step 3: Divide both sides by 6.

[tex]\frac{6x}{6}=\frac{60}{6}[/tex] [tex]x = 10[/tex]

Therefore, x = 10.

f(2) = 32 - 40 + 14 - 3

f(2) = 3

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that A chef preheats an oven. It starts at room temperature, 68°F, and heats up to 23°F per minute.

The equation will be written as:-

y = 23x + 68
