Answer:
[tex] \frac{14}{5} [/tex]
Step-by-step explanation:
1) Use this rule : a ÷ b/c = a × c/b.
[tex] \frac{7}{2} \times \frac{4}{5} [/tex]
2) Use this rule: a/b × c/d = ac/bd.
[tex] \frac{7 \times 4}{2 \times 5} [/tex]
3) Simplify 7 × 4 to 28.
[tex] \frac{28}{2 \times 5} [/tex]
4) Simplify 2 × 5 to 10.
[tex] \frac{28}{10} [/tex]
5) Simplify.
[tex] \frac{14}{5} [/tex]
Therefor, the answer is 14/5. And is decimal form it would be, 2.8.

i need help finding the area of these two
Answer:
50 cm² and 56 cm²
Step-by-step explanation:
The area (A) is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )
(2)
A = [tex]\frac{1}{2}[/tex] × (8 + 2) × (5 + 5)
= 0.5 × 10 × 10
= 5 × 10
= 50 cm²
(3)
A = [tex]\frac{1}{2}[/tex] × (12 + 2) × (4 + 4)
= 0.5 × 14 × 8
= 7 × 8
= 56 cm²

Answer:
Step-by-step explanation:
6) Let John's sister age be x
John's age = [tex]\frac{1}{2}x+7[/tex]
[tex]\frac{1}{2}x+7 = 35\\[/tex] {Subtract 7 from both sides}
[tex]\\\frac{1}{2}x=35-7\\\\\frac{1}{2}x=28\\\\x=28*2[/tex]
x = 56
His sister's age = 56 years
7) Longest side is hypotenuse. Use Pythagorean theorem.
hypotenuse² =base² + altituse²
15² = 12² + 9²
225 = 144 + 81
225 = 225
So, Pythagorean theorem is satisfied. So, 15cm , 12 cm ,9 cm will make a right angled triangle.
9) q = -1
7p + 5q -3 = 0
7p + 5*(-1) - 3 = 0
7p -5 - 3 = 0 {Combine like terms}
7p - 8= 0
7p = 8 {Divide both sides by 7}
p = 8/7
10) 8 - 3(x + 1) = 5 {Distributive property: a(b + c) = a*b + a*c}
8 - 3x - 3 = 5 {Combine like terms}
-3x + 5 = 5 {Subtract 5 from both sides}
-3x = 5 - 5
-3x = 0
x = 0
11) -20x⁴ - 7x³ + 5x² + 20 - ( 8x⁴ -7x² + 29x - 17)
= -20x⁴ - 7x³ + 5x² + 20 - 8x⁴ + 7x² - 29x + 17
= -20x⁴ - 8x⁴ - 7x³ + 5x² + 7x² - 29x + 20 + 17
= -28x⁴ -7x³ + 12x² - 29x + 37
kali runs 12 laps around a track each day. Each lap around the track is 400 meters. How many days will it take Kali to run the total of 12 kilometers?
Answer: 2.5 days
Step-by-step explanation:
First we should convert 12 kilometers to meters so that is 12000 meter. Now we know that she runs 12 laps each day and each lap is 400 meters so lets find out how much she runs in one day. 12 laps*400meters= 4800 meters
So an easy way to figure out how many days is to divide 4800 meters she runs each day from the total 12,000 meters she needs to run so 12,000/400=2.5.
It will take kali a total of 2.5 ( two and a half days) to run 12000 meters or 12 kilometers

Step-by-step explanation:
You are planning a trip to Yellowstone National Park, and know that you can save money by driving
and staying with family along the way. The first leg of your journey will be 426 miles from Portland,
OR to Boise, ID where your aunt lives. After visiting with her, you will drive 388 more miles to
Yellowstone. Estimate the number of miles you will drive to get to Yellowstone National Park by
first rounding to the tens place.
Answer:
the number of miles that you would drive to go the yellowstone is 814 miles
Step-by-step explanation:
The computation of the number of miles that you would drive to go the yellowstone is shown below:
= First leg of the journey from portland + more drives to yellow stone
= 426 miles + 388 miles
= 814 miles
Hence, the number of miles that you would drive to go the yellowstone is 814 miles

180 - 145 = 35 degrees
Answer:
35 degrees
Step-by-step explanation:
A triangle is 180 degrees and 45 and 100 is already there.
So... 180-45-100=35
That is how you get 35 degrees

On Monday, a museum had 350 visitors. On Tuesday, it had 680 visitors. Estimate the percent change in the number of visitors to the museum. Use pencil and paper. Estimate how many people would have to visit the museum on Wednesday to have the same estimated percent change between Tuesday and Wednesday as between Monday and Tuesday. Explain your answer.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that On Monday, a museum had 350 visitors while on Tuesday, it had 680 visitors. The percent change in the number of visitors to the museum will then be:
= (680 - 350)/350 × 100
= 330/350 × 100
= 94.29%
The number of people that'll have to visit on Wednesday to have the same estimated percent change will be:
= 680 + (94.29% × 680)
= 680 + (0.9429 × 680)
= 680 + 641
= 1321

Convert: a) 8250 g =________________kg b) 10 3/4 l =______________ ml c) 6 m 5 cm =_____________ cm d) 9 km 50 m =____________m *
Answer:
See answers below
Step-by-step explanation:
Convert: a) 8250 g =________________kg b) 10 3/4 l =______________ ml c) 6 m 5 cm =_____________ cm d) 9 km 50 m =____________m *
a) Note that 1000g = 1kg
8250g = x
1000 * x = 8250
1000x = 8250
x = 8250/1000
x = 8.25kg
b) 10 3/4 l to ml
1l = 0.001ml
10 3/4 l = x
Cross multiply
1 * x = 10 3/4 * 0.001
x = 43/4 * 0.001
x = 0.043/4
x = 0.01075ml
c) 6m 5cm to cm
Since 1m = 100cm
6m 5cm
= 6(100) + 5
= 600 + 5
= 605cm
d) 600km 50m to m
1000m = 1km
x = 9km
x = 9000m
600kn 50m
= 9000m + 50m
= 9050m
Explain how to draw a circle with a circumference of π2 inches. OPTIONS : The circle has a diameter of π2 inches, so use a diameter of about 1.6 inches. The circle has a radius of π inches, so use a radius of about 3.1 inches. The circle has a radius of 2π inches, so use a radius of about 6.2 inches. The circle has a diameter of π inches, so use a diameter of about 3.1 inches.
Answer:
he circle has a radius of π inches, so use a radius of about 3.1 inches.
Step-by-step explanation:
The circumference of a circle can be described as the linear distance round the circle
The circumference of a circle = 2nr
n = 3.14
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
diameter = 2r
If diameter = n2
diameter = 3.14 x 2 = 6.28
Radius = 1/2 x diameter = 6.28/2 = 3.1
The height in meters of a toy rocket at t seconds can be found by the
function h(t) = -5t2 + 40t + 1.2 Find the height of the toy rocket 4 seconds
after it is launched.
Answer: 81.2
Step-by-step explanation:
h(t) = -5t² + 40t + 1.2
h(4) = -5(4)² + 40(4) + 1.2 We plug 4 seconds as t, and solve h(4)
h(4) = -80 + 160 + 1.2
h(4) = 80 + 1.2
h(4) = 81.2
