Answer:
x = - 13
Step-by-step explanation:
- 0.4(x + 3) = 4 ( divide both sides by - 0.4 )
x + 3 = - 10 ( subtract 3 from both sides )
x = - 13

A solid's volume is 10 cubic inches. The solid is dilated by a scale factor of 3.5. Kiran says, "I calculated the volume of the image as 35 cubic inches, but I don't think that's right."
A. What might Kiran have done wrong?
B. What is the volume of the image
Answer:
she forgot the exponent on 3.5^3
Step-by-step explanation:
10 x 3.5^3 = 428.7428.75 u^3
The term "dilation" refers to a transformation. The volume of the dilated cube is 428.75 in³.
What is dilation?The term "dilation" refers to a transformation that is used to downsize an item. Dilation is a technique for making items appear bigger or smaller. The picture produced by this transformation is identical to the original shape.
As it is given that the volume of the cube is 10 cubic inches, therefore, the side of the cube is,
[tex]\text{Volume of the cube} = a^3\\\\ 10 = a^3\\\\a =\sqrt[3]{10}[/tex]
Now, we know that dilation always applies to dimensions, therefore the new dimension of the dilated cube will be,
[tex]\text{Side of the dilated cube} = \sqrt[3]{10} \times 3.5\rm\ in[/tex]
Further, the volume of the dilated cube can be written as,
[tex]\rm \text{Volume of the Dilated cube} = Side^3\\\\[/tex]
[tex]= (\sqrt[3]{10} \times 3.5)^3\\\\ = (\sqrt[3]{10})^3 \times (3.5^3)\\\\= 10 \times 3.5^3\\\\= 10 \times 42.875\\\\= 428.75\rm\ in^3[/tex]
A.) The mistake that Kiran made is that she didn't take the cube of the scale factor.
B.) The volume of the dilated cube is 428.75 in³.

A store pays a 5% commission on the first $300 of a sale. If the sale is
greater than $300, the store pays a 9% commission on the amount
above $300. Which is the commission on a $900 sale?
Answer:
$69
Step-by-step explanation:
First, we want to focus on the first $300
Multiply 300 by 0.05 to get the commission
300 x 0.05 = 15
Now, we solve for the first 300, let's solve for the remaining sales, which is 600 because 900 - 300 = 600
Multiply 600 by 0.09
600 x 0.09 = 54
Add the two sales commission numbers together
15 + 54 = 69

£150 is invested at 5% compound interest for 2 years. How much will be in the account at the end of the investment?
Answer:
165
Step-by-step explanation:
5% of 150 british pounds = 7.5 British pounds
2 years = 7.5 BS per year
7.5 + 7.5
= 15 british pounds
15 british pounds + 150 british pounds =
165 british pounds
y=6x+2
y=3x+1
solve with substution
6x + 2 and 3x + 1 are both equal to y, so they are both equal to each other.
6x + 2 = 3x + 1
3x = -1
x = -1/3
And plugging -1/3 in for x yields y = 0.

Question 5
Reduce: 12/14
the question is in the picture i attached. the right answer gets brainlist :) <3
Answer:
∠ 4 = 130°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 is an exterior angle of the triangle , so
∠ 4 = ∠ 1 + ∠ 2 ( substitute values )
11x + 9 = 6x + 6 + 4x + 14 , that is
11x + 9 = 10x + 20 ( subtract 10x from both sides )
x + 9 = 20 ( subtract 9 from both sides )
x = 11
Then
∠ 4 = 11x + 9 = 11(11) + 9 = 121 + 9 = 130°
your friend may have only calculated ∠ 1
∠ 1 = 6x + 6 = 6(11) + 6 = 66 + 6 = 72°

Find the value of x.
Answer:
x = 7
Step-by-step explanation:
The dashes on the lines show they are equal in length.
Therefore, by inspection of the diagram, we can see that the measures of the sides of the smaller triangle (with base 5x) are half the measures of the sides of the larger triangle (with base 70).
Therefore, creating an equation with this information:
5x = 1/2 x 70
⇒ 5x = 35
⇒ x = 7
Solution:
Note that:
2(Perimeter of smaller triangle) = Perimeter of larger triangle.This means that...
2(5x) = 70Simplify the equation and solve for x.
2(5x) = 70=> 10x = 70=> 10x/10 = 70/10=> x = 7The value of x is 7.

Which of the following probabilities is equal to approximately 0. 2957? Use the portion of the standard normal table below to help answer the question.

Probability of an event is the measure of its chance of occurrence. The event out of the listed events whose probability is 0.2957 is given by : Option C: [tex]P(0.25 \leq Z \leq 1.25)[/tex]
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z-score.
If we have
[tex]X \sim N(\mu, \sigma)[/tex]
(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] )
then it can be converted to standard normal distribution as
[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]
(Know the fact that in continuous distribution, probability of a single point is 0, so we can write
[tex]P(Z \leq z) = P(Z < z) )[/tex]
Also, know that if we look for Z = z in z tables, the p-value we get is
[tex]P(Z \leq z) = \rm p \: value[/tex]
Using the z-table, we get the needed probabilities as:
Case 1:
[tex]P(-1.25 \leq Z \leq 0.25) = P(Z \leq 0.25) - P(Z \leq -1.25) \approx 0.5987 - 0.1056 = 0.4931[/tex]
Case 2:
[tex]P(-1.25 \leq Z \leq 0.75) = P(Z \leq 0.75) - P(Z \leq -1.25) \approx 0.7734- 0.1056=0.6678[/tex]
Case 3:
[tex]P(0.25 \leq Z \leq 1.25) = P(Z \leq 1.25) - P(Z \leq 0.25) \approx 0.8944 - 0.5987=0.2957[/tex]
Case 4:
[tex]P(0.75 \leq Z \leq 1.25) = P(Z \leq 1.25) - P(Z \leq 0.75) \approx 0.8944 - 0.7734 =0.1210[/tex]
Thus, the event out of the listed events whose probability is 0.2957 is given by : Option C: [tex]P(0.25 \leq Z \leq 1.25)[/tex]

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The figure is shown.
Let the unknown side = y
Now, For upper triangle, we can use Pythagoras theorem as;
⇒ 25² = y² + 16²
⇒ 625 = y² + 256
⇒ y² = 369
⇒ y = √369
⇒ y = 19.2
Hence, The value of x is find as by using Pythagoras theorem as;
⇒ 19.2² + x² = 22²
⇒ 368.6 + x² = 484
⇒ x² = 484 - 368.6
⇒ x² = 115.4
⇒ x = √115.4
⇒ x = 10.7 units
