If (x,83) is a solution to the equation 2y=1/2(98x+38), find x.
Answer:
X= 2y/49 - 19/49
Answer:
because (x; 83) is a solution to the equation
2y=1/2(98x+38)
=> 2.83 = 1/2(98x + 38)
<=> 4.83 = 98x + 38
<=> 332 = 98x + 38
<=> 98x = 294
<=> x = 3
-8x + 40 > -16 pls step by step
Answer:
x <7
Step-by-step explanation:
Subtract 40 from both sides.
-8x>-16-40
2 Simplify -16-40 to -56.
-8x>-56
3 Divide both sides by -8−8.
[tex]x < \frac{56}{8} [/tex]
4 Two negatives make a positive.
[tex]x < \frac{56}{8} [/tex]
5 Simplify 56/8 to 7

An iron ball has a density of 4 g/cm3.
The volume of the ball is 15 cm3.
What is the mass of the ball?
========================================================
Explanation:
m = mass
v = volume
d = density
The formula we use is
d = m/v
Multiplying both sides by v allows us to solve for m
d = m/v
d*v = m
m = d*v
Now plug in the given density (d = 4) and the given volume (v = 15) and simplify:
m = d*v
m = 4*15
m = 60 grams
Note how,
d = m/v
d = 60/15
d = 4
which helps confirm our answer

Three of the paths in a city park form a right triangle, as shown on the map. Each unit on the map represents 10 meters. The city plans to plant trees along these paths.
The perimeter of the triangle is 188.1 m
How to find the perimeter of the triangle?
The perimeter of a triangle can be determined by adding the three lengths of the triangle.
From the image, the coordinates of vertices of the triangle are:
(-3, 3), (-3, -2) and (3, 3)
distance between (-3, 3) and (-3, -2) is:
3-(-2) = 5 (we use y coordinates only because x are the same)
= 50 m (Each unit on the map represents 10 meters)
distance between (-3, 3) and (3, 3) is:
3-(-3) = 6 (we use x coordinates only because y are the same)
= 60 m
distance between (3, 3) and (-3, -2) is:
= √(50² + 60²) (Pythagoras)
= 78. 1 m
Perimeter = 50 + 60 + 78.1 = 188.1 m

(1 point) Question 7 options: 1) It is symmetric and has no gaps. 2) It is not symmetric and has a peak at $5.00. 3) It is a cluster from $1.00 to $5.00 and has gaps. 4) It is a cluster from $1.00 to $5.00 and has a peak at $5.00.
Answer:
A. It is symmetric and has no gaps.
Step-by-step explanation:
Given

Select the true statement
From the attached plot, we can see that
The plot is bell shaped (by tracing the number of dots on each dataset) There is no gap between each dataset (from 4 to 7)Since (1) all bell shaped distribution are symmetric and (2) there is no gap between the dataset, then (a) is correct.

The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)
Answer:
94.86 miles per hour
Step-by-step explanation:
The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)
The appropriate customary unit is calculated as:
1 km = 0.62 miles
153 km = x
Cross Multiply
x = 153 × 0.62 miles
94.86 miles
Therefore, the appropriate customary unit is 94.86 miles per hour
ok ik but i need help with this i think i got it tho -275=2x -50
Answer:
-112.5
Step-by-step explanation:
2x - 50 = -275
2x = -225
x = - 112.5
Answer:
x = -225/2 (or) -112.5
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ -275 = 2x - 50
Then the value of x will be,
→ -275 = 2x - 50
→ 2x - 50 = -275
→ 2x = -275 + 50
→ 2x = -225
→ x = -225/2
→ [ x = -112.5 ]
Hence, value of x is -112.5.

A park has a triangular sandbox. Todd wants to create a smaller sandbox at his backyard having the same angles as the park sandbox. Drawings of both sandboxes are shown. 18 ft 20 Park Sandbox 8+ Todd's Sandbox What is the perimeter, in feet (ft), of Todd's sandbox?
Answer:
the perimeter is
104/5 feet or 20 4/5 ft
Step-by-step explanation:
The perimeter is a loop that surrounds, circumscribes, nor defines a two-dimensional shape and a one length.
Perimeter Calculation:A park's sandbox measures [tex]20 \ \text ft[/tex] in diameter at its base.
Todd's sandbox has a [tex]4 \ \text ft[/tex] base.
Now [tex]\frac{4}{20}=\frac{1}{5}\\\\[/tex]
As a result, the scale factor for smaller sandboxes is [tex]\ \frac{1}{5}\\\\[/tex]
[tex]\to 14 \times \frac{1}{5} = 2.8\\\\\to 18 \times \frac{1}{5}= 3.6\\\\[/tex]
As a result, in Todd's sandbox, the missing lengths (in feet) are 2.8 and 3.6.
Todd's sandbox has a perimeter of [tex]4 + 2.8 + 3.6 = 10.4[/tex] feet.

The spinner is shown has eight congruent sides the spinner is spun 200 times. What is a reasonable prediction for the number of times the spinner will land on 2 or 3
Answer:
50 times
Step-by-step explanation:
Total number of faces = total possible outcomes = 8
Number of 2 or 3 on spinner = required outcome = 2
Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes
P(2 or 3) = 2 / 8 = 1/ 4
From 200 ; prediction for the number of 2 or 3
1/4 * 200

16 girls and 14 boys put their names in a bag. One name is drawn from the bag. What is the probability that a boy's name will be pulled
Answer: [tex]\dfrac{7}{15}[/tex]
Step-by-step explanation:
Given
There are 16 girls and 14 boys
The favorable chances that a boy name comes up are 14
Probability is given by the ratio of favorable chances to the total chances
So, the probability that a boy's name will be pulled is
[tex]\Rightarrow P=\dfrac{14}{14+16}\\\\\Rightarrow P=\dfrac{14}{30}\\\\\Rightarrow P=\dfrac{7}{15}[/tex]
