A shape is shown on the centimetre grid below.
Work out the area of the shape after it has been enlarged by scale factor 2.
State the units of your answer.
Answers
Answer:
The area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
Step-by-step explanation:
The Area is basically a measure of how much space in square units there is inside an object.
As the shape is shown on the centimeter grid.
The shape clearly occupies the space of 5-centimeter squares.We also know that If the scale factor > 1, the image is enlarged.
As we know to determine the area of the shape after it has been enlarged by scale factor 2, all we need to do is to multiply the area of the original shape by 2.
The area of original shape = 5 cm²
The area of the shape after the dilation by a scale factor 2 = 5 × 2 = 10 cm²
Thus, the area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²

Step-by-step explanation:
Let [tex]x[/tex] be the temperature on the first day
Second day temperature
[tex]x+7[/tex]
Third day temperature
[tex]x+7-10[/tex]
Fourth day temperature was [tex]1^{\circ}\text{F}[/tex]
[tex]x+7-10+6=1\\\Rightarrow x+3=1\\\Rightarrow x=1-3\\\Rightarrow x=-2^{\circ}\text{F}[/tex]

Step-by-step explanation:
4(x-1) = 2(6-2x)
x=2
Answer:
x=2
Step-by-step explanation:
4(x-1)=2(6-2x)
4x-4=12-4x
Add 4 to both sides
4x=16-4x
Add 4x to both sides

A ladder is placed against a wall such that the top is 8 feet above the ground. If the ladder is 10 feet long, how far away from the wall is the base of the ladder
Answers
Answer:
6 feet
Step-by-step explanation:
Consider the right triangle formed by the wall, ladder and ground.
Let the distance the ladder is from the wall be d , then
Using Pythagoras' identity in the right triangle
The square on the hypotenuse ( ladder) is equal to the sum of the squares on the other 2 sides ( wall and d ), then
d² + 8² = 10²
d² + 64 = 100 ( subtract 64 from both sides )
d² = 36 ( take the square root of both sides )
d = [tex]\sqrt{36}[/tex] = 6
That is the ladder is 6 feet away from the wall

The downward-sloping line has a y-intercept of 1 and a slope of -2, so its equation is ...
y = -2x +1
The graph is shaded on and above that line, so the inequality it represents is ...
y ≥ -2x +1
__
The upward-sloping line has a y-intercept of +4 and a slope of +2, so its equation is ...
y = 2x +4
The graph is shaded on and below that line, so the inequality it represents is ...
y ≤ 2x +4
Then the system of inequalities is ...

Payton spent half of her weekly allowance on clothes. To earn more money, her parents let her clean the oven for $8. What is Payton weekly allowance if she ended with $15
Answers
Answer:
Payton's weekly allowance is $14.
Step-by-step explanation:
If she ended up with $15 after earning $8, then we to subtract 15 by 8.
15 - 8 = 7
If Payton spent half of her allowance before earning more money from her chore, then her allowance must be 7 times 2.
7 x 2 = 14.
Therefore, Payton's weekly allowance is $14.

Superstar Music Club Equation: [tex]\$3.50x[/tex]
Solution: 2
Step-by-step explanation:
Given that:
1st choice music club:
Charges for one song = $1
Charges for sign - up = $5
Let the number of songs = [tex]x[/tex]
Total cost = [tex]\$5+\$1\times x = \$(x+5)[/tex]
Superstar music club:
No sign up fee and
Charges for one song = $3.50
Total cost = [tex]\$3.50x[/tex]
Given that, cost of each music club becomes equal:
Putting them same:
[tex]x+5=3.5x\\\Rightarrow 2.5x = 5\\\Rightarrow \bold{x =2}[/tex]

Deon throws a ball into the air. The height h of the ball, in meters, at time t seconds is modeled by the function h(t)=-5t^2+14t+3 When will the ball hit the ground
Answers
Answer:
The time the ball will hit the ground is 1.4s
Step-by-step explanation:
Given;
function of the ball's motion; h(t)= -5t²+ 14t + 3h
The final velocity of the ball, v , is given as;
v = dh/dt
v = -10t + 14
When the ball hits the ground, the final velocity, v = 0
v = -10t + 14
0 = -10t + 14
10t = 14
t = 14 / 10
t = 1.4s
Therefore, the time the ball will hit the ground is 1.4s

Answer:
7 pink flowering plantsStep-by-step explanation:
Total number of plants = 15Total cost = $96Cost of pink flowering plant = $8Cost of purple flowering plant = $5Let x and y be the number of plants bought. Then we have equations:
8x + 5y = 96x + y = 15 ⇒ y = 15 - xSubstituting y in the first equation:
8x + 5y = 968x + 5(15 - x) = 968x + 75 - 5x = 963x = 96 - 753x = 21x = 7Correct option is the second one

The tape diagram represents the ratio of the numbers of planets in two different solar systems. There are 8 planets in Solar System B. How many planets are in Solar System A?
Answers
The correct answer is 6 planets
Explanation:
The image presented shows the ratio of planets in solar system A vs those in solar system B. In this way, the general ratio is 3 : 4 or 3 to 4; this means for each 4 four planets in solar system B there are 3 planets in solar system A and vice versa. Now, to find the total of planets in system A if there are 8 planets in system B, follow this process:
8 planets / 4 = 2 planets - This means each of the sections in the diagram represents 2 planets
2 section x 3 = 6 planets as in the solar system A there are 3 sections and each of this represents 2 planets, the total of planets in this system are 6
This result can also be found by converting the ratio to a fraction and multiplying this by the 8 planets
8 planets x [tex]\frac{3}{4} = \frac{24}{4} = 6[/tex]

[tex]6x - 21 + 21 = 3 + 21[/tex]
[tex]6x = 24[/tex]
